Me the ability to power AC electronics off the solar panels. The boom box was the only load that got consistent use besides the motor. I found pedaling to the rhythm of my personal music selections to be blissful it made riding even more enjoyable than it already was. I am starting a small business selling solar trikes and trailers over the Internet. Initially, I am focusing on the solar-powered recumbent tricycle. Rather than having the PV canopy over the trailer, as my first solar cycle had, the PV is over the trike, providing shade and rain cover. Recumbent trikes have two wheels in the front, and because they are very low to the ground, they are incredibly stable. Like the solar trailer, the solar trike is also a contained and mobile power station.

Once a system is installed, people seem to fantasize about more solar panels or more battery capacity. I assume that since the energy is green, people feel justified in running as much stuff as they can.

Nomad 300

In trying to cool the house, the Hoovers tried some portable swamp coolers. These helped some, and for more improvement, they changed to window-mounted swamp coolers powered by Siemens solar panels. These worked just well enough to be teasers. The water source had enough mineral salts to rapidly build deposits (mostly magnesium). Maintenance was a problem, so they decided to search for something better. In 1998, Bill came to me asking about air conditioning. For several years, I have been his consultant on their renewable energy system, and I designed the original power system for their home. When Bill discovered an Internet company selling air conditioning that could run on solar panels, I was skeptical, thinking of the energy demands of a typical compressor. The upshot of this is that Bill and Carol now have a three-ton air conditioning unit powered by solar energy and propane. House temperatures are now in the comfort zone, despite outside temperatures that are typically in the 90s...

For Function For Form For Life

Ceramic tile performs as an energy saver, as well, retaining heat and emitting It slowly, for efficient building climate control. Partnerships with Spain's pioneers In solar energy have resulted In a patented system of photovoltaic facades. Tiles clad with solar cells actually produce energy year round. Ventilated facades - photovoltaic or not - create a thermal barrier between building surface and tile, conserving energy, and reducing heating and cooling costs and noise pollution.

Water Powered PV Tracker

This is the second water-powered tracking system I have built. I first came up with the idea several years ago after installing my first solar powered pumping system on another, very low-producing well. I mounted a single 50 watt PV panel on a fixed mount, figuring this low-powered setup would approximately match the well's low water production. The well turned out to produce more water than the solar-electric system could extract each day. So I looked at using a tracking mount to boost pump output.

Passive Solar Building Design

Solar energy travels through the windows of a building, increasing the energy used by air conditioners and degrading occupant comfort. An ideal passive solar building minimizes internal energy use by optimizing its design to suit the annual path of the sun and the local climate. A primary goal in energy-efficient design for buildings in warm climates such as Shenzhen is that they must minimize solar heat gain during much of the year. Based on solar energy calculations for each window direction (north, south, east, and west), recommendations were made regarding optimum window shape and orientation, as well as shading options. The passive design incorporated knowledge of the sun's path, including sun angles during different days and azimuth angles (sun-path from a bird's-eye view) throughout each day of the year. Figure 6 shows elevations at noon on three dates for Shenzhen (latitude 22.18 N), and Figure 7 shows azimuth angles for Shenzhen throughout the day on those dates. In addition...

Letters to Home Power

Please note, too, the poster that went out with every issue. It promised-- among other coming articles-- pieces on wind, water, solar, and methane power. And that was back when the rest of the world was telling us that all the streams have already been harnessed, solar energy was tried in the 30's and didn't work, wind power is just too much trouble, and what the hell is methane anyway I like this Home Power issue and look forward to more. I have a comment about Solar Power that has nothing to do with the efforts of this magazine. I am converting to solar power when I already have commercial AC power. Because I don't believe in fossil fuel pollution or nuclear waste. It bothers me that most people involved in selling solar power insist on making a high wage, which helps to keep solar power very expensive. Therefore, the average homeowner sees no logical reason to convert from AC commercial to clean solar power. It is advised, when charging a battery, to continue charging until the...

Daybreak Energy for Your

12 VOLT WASHING MACHINE In response to A.L.'s letter in 8, we offer a solution. We have produced an AUTOMATIC WASHER CONVERSION KIT since 1983, for both 12 and 24 volts. It adapts Kenmore and Whirlpool washers (only). 120 vac power is required to run the timer and controls, but the smallest available inverter (100 watt) can handle that. The big job of running the machine is handled by a high efficiency DC motor. This eliminates the need for a 2000 watt inverter, and uses much less energy too (average 25 amps at 12V). The kit is pre-wired and simple to install. A similar conversion is available for gas driers.

Robert L Neuileb PhD and Marilyn K Neulieb MS

With study, ingenuity and determination, the sun's energy may serve many of our needs. Technologies to capture the winds and radiant solar energy are emerging. However, there is no assurance that the use of solar energy will create order on the earth. For millions of years, fires on prairies and forests alike have been started by lightning from sun-driven storms. The magic sun has repeatedly converted prairies and forests into a disordered scattering of ashes. The sun can work its magic for man, but it comes with no guarantees, only opportunities.

Using solar distillation PVs for pumping

Practically any seacoast and many desert areas can be made inhabitable by using sunshine to pump and purify water. A 10 gallon day solar still now purifies sea water for drinking, cooking and other household needs for a residence near George Town, Exuma, in the Bahamas. Solar energy does the pumping, purification, and controls seawater feed to the stills. Purify your water with Solar Energy

The multiple decks and terraces of architect Ray Kappe's exploded box design (right) expand living space by extending it outdoors. Drought-resistant native plantings add vibrancy while requiring little water or maintenance. Photovoltaics integrated into awnings and attached to trellises (above) collect solar energy while helping provide shade. Active solar technologies include a 2.4-kW rooftop solar array linked to a battery storage system that generates 60 percent to 75 percent of the home's electrical power. A solar water heater (also situated on the roof) serves the radiant floor heating and domestic water systems, and some of the solar panels double as awnings to shade roof decks.

Other means of heat storage

This means of energy storage is superior to all the above means. The classic example is petroleum. Solar energy has been stored in plant material, which decomposed into oil, and now millions of years later, with no energy loss during the storage, 10,000 kWh m3 can be released by simply burning it -an incredible energy density. The only small problem is that the rate of use exceeds the rate of geological production, given the millions of years' time span

Water storage technology

Klagenfurt University

The storage need in a solar system is often determined by the ratio of the maximum to minimum monthly solar radiation. Figure 13.1.2 gives this data for different latitudes. When the maximum-minimum ratio is less than 5, even wintertime solar energy may be enough to provide the heat load, whereas values higher than 10 mean such a large fluctuation that a seasonal storage or

Groundcoupled and geothermal heat

Geothermal heat can be used to generate electricity and heat but the geology of Central Europe limits its application for heating purposes. In spite of its huge energy potential, this environmentally friendly technology is currently only rarely used. In comparison to solar energy that reaches the Earth (5.4 x 1015 MJ a), the terrestrial heat flux through the Earth's crust is nearly 6000 times smaller (1012 MJ a). This is, however, still three times greater than the total worldwide energy consumption.

Carsten Petersdorff 1231 Concept

In high-performance houses, while the heat demand is reduced to a very low level and occurs during only a few months of the year, it does not decrease to zero. Certainly, a significant part of the space heating and major part of the hot water demand can be covered by solar energy. However, to cover 100 per cent of the demand would be economic nonsense. Such a system would be grossly over-dimensioned most of the year, having to dispose of heat. A backup heating system to cover the peaks is essential. Burning a fossil fuel is a proven means of providing this backup. Due to the small absolute quantities of fuel consumed, the environmental impact is negligible. Especially in high-performance houses, the following should be considered

Active solar heating Water

Heating DHW with solar energy in a high-performance house is sensible. In such houses, the energy needed to heat domestic water can equal or even exceed the energy needed for space heating since the latter has been so far reduced by insulation and heat recovery. Furthermore, demand for heating domestic water is a 12-month energy demand, including the high insolation summer months. Using a solar system is therefore an effective way of reducing the total primary energy demand. Increasingly, the market for solar water systems also includes systems that provide, in addition to water heating, space heating in winter.

Motorized Sources for Equalizing Charges

A lawnmower powerplant just to equalize their batteries. The very nature of wind and solar energy makes it very difficult to equalize the batteries without such a motorized power source. This generator makes excellent backup power for times when Mother Nature isn't cooperating with our energy demands.

Recommendations for Windows and Walls

As shown in Table 2, solar gain through windows accounts for approximately 40 percent of the total cooling energy load for a base case unit in Shenzhen. Over a year, the energy from direct sunlight per area incident on all building surfaces (north, south, east, and west) totaled nearly 2.53 MWh 2. Northern windows received 3 percent of the total direct annual solar energy per area, while southern windows received 33 percent, and western and eastern facing windows each received 32 percent (64 percent combined). As a result, it was desirable that building designs minimized western and eastern exposures in order to maximize energy-efficient designs. Recommendations for window design in Shenzhen follow in the next several paragraphs.

Careers in Photovoltaics Start with Training

Job placement in the solar energy field, particularly in photovoltaics, has become more like job selection for graduates of the Colorado Mountain College Solar Program. Energy Technologies Symposium and International Exposition (RETSIE) and the annual meeting of the American Solar Energy Society (ASES). Groups and organizations sponsoring CMC trainees include the PV industry, Peace Corps, Department of Defense, World Health Organization, Agency for International Development, state and local governments, university and national solar energy laboratories. In addition the CMC instructors have authored numerous technical papers published by the International Solar Energy Society and the American Solar Energy Society. Magazine articles on the CMC Solar program have appeared in PV International, Solar Age, Energy Report, Mother Earth News, and Energy Talk.

Energy performance and performance calculation

For solar wall heating and solar insulation, the same methodology can be used for characterizing the wall construction. The U-value can be calculated according to ISO 6946 (EN ISO 6946, 1996). In general, the wall construction is an inhomogeneous building element consisting of wall material, transparent insulation product and frame part. Similar to a window, the solar gains are proportional to a total solar energy transmittance (g-value) of the complete system gSWH - or, in collector terminology, a solar efficiency nSWH. The basis for the determination of this parameter is the thermal resistance network of Figure 9.4.6 the solar energy transmitted is proportional to the g-value of the transparent insulation gTI and the relation of the resistance from the wall surface to the exterior Rtii + R to the total resistance R

Saving Energy Saves Money

After space heating and cooling, the largest user of home energy is usually the hot water heater. Fortunately this energy drain can easily be reduced with only moderate expense. Some people seem to think that solar hot water was a 70's fad, and faded with the times. Not true Solar hot water was very popular in the Los Angeles area in the early 1900's, and disappeared only when the hot water heater manufacturers gave people free gas and electric hot water heaters in exchange for their old-fashioned solar units, assuring a perpetual market for their supplies of then cheap gas and electricity. Well, it may have made sense back then, but one quick glance at our utility bill tells us that we've been had. A family of four often spends 50 per month or more to operate their electric hot water heater. Solar energy is presently making hot water for thousands of people all over the world, many in climates where sunshine is limited. Solar hot water does not have to be complicated or expensive. A...

Utilities Meet Solar Challenge

O Last October, Julia Hamm, executive director of Washington, D.C.-based Solar Electric Power Association, challenged solar and utility industries to deploy solar power on a massive scale despite new economic barriers. SEPA recently issued a report demonstrating the industry has responded. The 2008 Top Ten Utility Solar Integration Rankings report identifies those utilities in the U.S. that have the most significant amounts of solar electricity integrated into their portfolio and records the increased collaboration of U.S. electric utility and solar energy industries. The overall installed solar capacity of the Top 10 ranked utilities rose from 711 megawatts to 882 megawatts, reflecting a 25 percent growth since the challenge was issued. Ninety-two utilities participated in this year's survey. Renewable portfolio standards, impending carbon policy, and fluctuating costs of power generation and fuel resources top the list of drivers towards improved perception of solar electric...

Design Principles For Sustainable Urban Housing In China

Others are about quality of life and the ability of people to live together without alienation. At the qualitative building level, the design team at MIT sought design solutions where the housing can be far more energy efficient, principally through the reduction of air-conditioning and improvements in the design of the building fabric, to reduce carbon dioxide emissions through the dependence upon climate-destructive energy sources such as coal-fired power plants, and to maximize the use of natural ventilation and solar energy for daylighting and winter heating. At an urban scale, we sought to develop plans that were more ecologically responsive in relation to water conservation and retention, wind patterns in and around buildings, and to landscape space that built a sense of community. However, rather than developing a design that might contain a large palette of available sustainability techniques, we sought to develop an understanding of those that would work best, that would be...

Heat production and distribution

The 48 single family houses in the southern tract have a micro-district heating system per house row. Solar heat and electricity produced on the house roof tops are also centrally collected and distributed. Solar energy also covers 65 per cent of the DHW need. These central units are managed by the local utility.

Experience with Appliances

Encouraging the use of energy-efficient appliances requires that standards be introduced and that consumers are aware of energy efficiency. Several energy efficiency programs have been introduced in China to date, with mixed success.The China Green Lights program addresses two major barriers to reform, the high initial cost of efficient technologies and poor quality of some of the products manufactured in China. Screw-in compact fluorescent lights have been observed to fail very prematurely, negating the life cycle savings and losing consumer acceptance. The CFC-Free Energy-Efficient Refrigerator Project aims to improve the energy efficiency of Chinese refrigerators through a series of

The Edge The Edge Ah Yes The Edge

We can look at the relatively inexhaustible resources which are available to us right now. If these can be effectively harnessed we will be all right energy wise for at least a million years. Two of these, wind and water, have been used for many years as energy saving and energy creating systems. These will be here as long as the Earth survives. Another, solar, will be around even longer. It is the opinion of many intelligent people that with proper technological engineering these three sources alone could provide all the energy that human society needs. Solar energy is also the best bet to power many extraplanetary ventures.

The lights have not replaced the candles completely as we still love the soft glow of candles. There is obviously a place for both forms of energy.

Basic Principles

Example, (4) home ventilating or cooling uses excess solar power exactly when it is needed most. (3) Water storage for irrigation has enormous potential for making the most of solar power, especially because the most water is required when there is the most sun It is ideal to store at least a two week supply of water. When your storage tank fills, allow it to overflow to some trees the GROUND stores water energy too Use drip irrigation, mulching etc. to minimize evaporation losses. (4) House or attic ventilation or cooling is a prefect way to blow off excess summertime solar power during hot weather.

However, much has happened since the fall of Said Barre and the American Blackhawk debacle of the early 1990s. Peace has come to the northern regions, now called Somaliland and Puntland, and elections in Djibouti are breathing fresh hope for peace in the ragged war-torn regions of the south. With all electricity infrastructure destroyed, and among the best solar resources in the world, many Somalis are committed to using solar energy as a new building block for their infrastructure. Given that Somalia has largely been isolated from the rest of the world over the past ten years, it has not been exposed to the solar revolution. People in rural areas have concentrated on simply surviving and avoiding conflicts. So an entire generation of people is without education and relevant skills. As bright as they are, our students have had little opportunity to access formal education. When Frank began holding introductory classes, he had to start with the basics, from DC...

A length of wire is known to have a resistance of 2W. If the wire is carrying 11A of current, how much Electro-Motive-Force or voltage E will be lost in the wire and i how much power is lost as heat in the wire Solution E IR E 11A x .2W 2.2V. . The power that is lost in the wire can be found using P IE P 11A x 2.2V 24.2 Watts W . This would be about half of the available power from a typical solar-panel.

Fuel cells

Fuel cells, like batteries, are electrochemical power sources. Whereas batteries store energy, fuel cells transform energy. A fuel cell steadily supplied with fuel generates electricity. The fuel can be virtually any chemical substance containing hydrogen. When hydrogen alone is not readily available as a fuel, it can be produced from substances such as natural gas, oil or methanol by a process called 'reforming'. Reforming, however, consumes energy, produces waste heat and is generally not emission free. Ideally, hydrogen is produced from water by electrolysis, where the electricity is generated by solar power (solar hydrogen).


The second silo now houses state-of-the-art equipment that cleans and reuses up to 200,000 gallons of fresh and salt water at a time. In comparison, the center's old facility could handle only 43,000 gallons of water. Employing salt-water brining, backwash recovery, and solar-powered processing equipment, all of the center's water is reused with the exception of water that is lost to evaporation or used for cleaning.

More on Entropy

If a system can produce energy transitions within an ultra-short time interval, then the possibility exists for free energy during this interval. Free energy may lurk in the cracks between our perceptual intervals. In order to use this energy, a collection and storage system must only receive energy from the ultra-short system. This second system may be a one-way, inductive field system with internal dynamic equilibrium.

The Role of Policy

Has been in the development of energy standards for appliances. Programs such as China Green Lights and the CFC-Free Energy-Efficient Refrigerator Project have extended the traditional technology-based efforts by reaching consumers, dealers and other stakeholders with the product information needed to make responsible choices. Furthering the success of these projects is a new, unified energy informational label developed by the China Sustainable Energy Project (CSEP). The project encapsulates three key aspects of China's policy initiatives mandatory energy efficiency standards, mandatory (and unified) energy information labeling, and voluntary energy efficiency labeling. In August of 1999, China formally launched the label, awarding the first one to refrigerators. These ideas must be transferred to the building material industry to give the necessary instruction and incentive to supply certified, quality insulation, windows, and other products.

Making solar energy pay Solar energy is a subject that often comes up. According to BC Hydro, the average B.C. household uses 122.2 kilowatts of energy per day, making the family home one of the premier energy users. There are two options when it comes to solar energy. Photovoltaic, which converts solar energy into electricity and solar hot-water heat that harnesses solar energy to heat only the water used in the home.

Floor Finishes

The concrete floor slab, representing a large thermal mass, could store solar energy during the day for release later at night. This would utilize excess solar energy at night that otherwise would not be harnessed, and could help to reduce peak heating loads late at night. However, heat transfer to and from the slab could be hampered by the use of insulating finishing materials such as carpet or woods, as shown in Figure 17. Though the heating rate from the floor was substantially improved when the slab was very thick, the consequent increased construction costs and materials did not justify the benefits.

Solar Energy Research Institute (SERI) Another one of SERI's partnership efforts is paying off. The biggest news in solar cell research this year, according to Jack Stone, Director of Solar Electric Research at SERI, is ARCO Solar's new low-cost 1 square foot solar panel. Fabricated of copper-indium-diselenide (CIS), the new panel converts 11.1 percent of the sun's energy into electricity, a 30 percent increase in prior performance levels.


Features affecting the energy use of a typical residential unit. These energy simulations were created using the DOE-2 building energy simulation program (AEC 2006). The program performed a dynamic energy balance at each hour of the simulation period, accounting for heat flows across the building's exterior surfaces, heat gains from solar energy, lights and equipment, and heat storage in the building structure. It computed indoor temperatures when the building was not conditioned, and heating or cooling loads when equipment was used to maintain aspecified indoortemperature.Simulations took into account the building geometry, equipment, materials, surroundings, occupants, and other details that affect energy usage. These simulations were performed using natural ventilation with airflow of five to ten air changes per hour (ACH) air-conditioning was used to maintain comfort conditions when natural ventilation was not sufficient. In the CFD studies presented later in this case study, the...

While multi-national corporations commit massive resources to developing photovoltaics, small companies and private inventors are putting PV power to use in small-scale, appropriate applications. Special water pumps required for solar use are among these innovations. Solar power differs fundamentally from conventional electric or engine-powered systems, so solar pumps often depart from the conventional. PV arrays produce DC power, rather than the AC from conventional sources. And, the power available varies with the sun's intensity. Since it costs less to store water (in tanks) than energy (in batteries) solar pumps tend to be low in power, pumping slowly through the duration of the solar day. This article is vague, of necessity -- the subject matter could easily fill an entire book AND a good sized catalog. Solar pumps are utilizing many new, innovative designs and specifications are ever-changing. For more information, refer to the latest catalogs from PV suppliers, and consult a...

Solar insulation

Non-transparent materials like cardboard structures or mineral wool can also be used in wall constructions for utilization of solar gains, when covered with a glazing instead of an opaque construction, see Figure 2.4.2. The efficiency of these systems is certainly rather low. The intention here is not to convert the wall into a solar collector but to use the solar gains to reduce the heat losses further down towards approaching the zero energy balance over the heating season. The absorbed solar energy is used mainly to raise the average temperature of the outer shell to the interior temperature level thus bringing down the average temperature gradient over the heating season. There will be no solar heating, but the insulation level will be increased without using too large material thickness.

Solar wall heating

With a transparent insulation element covering the outside of a massive wall, this part of the building can be converted to a solar wall heating area. Solar energy is converted to heat at the absorber and conducted with a phase delay of some hours - depending on thickness and building material -through the massive wall into the interior. This is the reason why windows and solar wall heating with transparent insulation fit very well together the solar gains of a south-oriented solar wall reach the room mainly at night time and thus extend the period with passive solar heating considerably.

The objective of the project was to build houses that are affordable for young families. Therefore, the houses were targeted to cost between 180,000 and 235,000 Euros (including VAT and the building site). The ministries in North Rhine-Westphalia coordinated their subsidy programmes for solar energy housing estates. As a result, photovoltaic and solar thermal systems were subsidized. The local energy utility also supported the solar systems.

System Operation

John and Anita are their own power company. They both watch their battery voltage and electrical consumption like hawks Generating their own electricity has taught them the lessons of conservation and energy management. They are looking forward to completing their system by adding more PVs and more batteries. Four more PV modules will make them almost totally solar powered. This will reduce their operating expenses and allow them to use more energy. Anita has a washing machine on the back porch that she's giving the eye. Since the data was collected for this report, John has moved his refrigerator freezer. This move from the warm kitchen to the much colder back bedroom has cut John's wintertime power consumption by about 40 . One such details the success or failure of AE systems rest.

Power Sources

The Pryors use two energy sources- photovoltaics and a homemade 12 VDC gasoline engine generator. The computer specified eight PV panels, each 48 Watts, for this system. However, finances forced John and Anita to make do with only four 48 Watt Kyocera photovoltaic modules. These 4 modules produce about 950 Watt-hours of energy on an average sunny day at John & Anita's location. This makes their system about 47 solar powered. One of the nice things about PVs is their expandability. John and Anita can add more panels to their system whenever they wish. The cost of the four Kyocera PV modules was 1,400.

I3 The technologies

As mentioned at the beginning of this chapter, the first objective is to ensure that the heat inside remains inside during the heating season, and that the heat outside stays outside during summer. This is the job of the envelope. For comfort and energy reasons, the envelope must be air tight, so the next job is to guarantee a supply of fresh air - hence, a ventilation system is needed. The third job is to produce and distribute the small amounts of heat still required for space and water heating. The final job is to supply the electricity. As with building heating, the first objective is to minimize the need for electricity. According to the budget of the client, electricity can then be produced from solar energy.

Exemplary buildings

The row houses in Gelsenkirchen, Germany, provided an ideal field laboratory to examine how effective different constructions and design are in achieving high performance. Of interest here was not just the energy consumed over the operational life of the buildings, but also energy consumption over the whole life cycle, from construction through 50 anticipated years of service to demolition at the end. It was also interesting to see what proportion the infrastructure (streets and utilities) make of the total energy picture of a community. The project also served as a demonstration project, promising the transition from a coal and heavy industry economy and fossil fuel dependency to a new era based on solar energy. This was one of the first of an ambitious state programme to build 50 solar communities.
