Info

Our system has been operating for a little more than two years now, and for the most part, it needs very little attention. Our batteries need water about once each season, and aside from occasional breakdowns (see sidebar), all we do is keep track of energy production and battery levels about once a day, and forget about it. We have included highlights from our log sheets over the last seven months. We rarely make what we expected on each sunny day throughout the course of the summer. There are...

Judy's pueblo-style home is about 1,800 square feet (167 m2), plus a two-car garage, and is made with Perform Wall. Perform Wall is made of 85 percent recycled Styrofoam and 15 percent Portland cement. It looks and stacks like long cinder blocks (10 feet long by 10 inches wide by 15 inches high 3 m x 25 cm x 38 cm), and has cores filled with rebar and concrete. The 10 inch Perform Wall has a laboratory tested (real) R-value of about 11. The high thermal mass due to the concrete mixture and...

Heatpump Open Loop Lake

Heat is transferred from the condensing refrigerant to the water circulating through the space heating system Heat is transferred to space via underfloor heating, radiators, etc. Pipes are laid at a depth of 3 to 5 feet 0.9-1.5 m . If the pipe is buried too deep, it reduces the ability of the incident solar energy to replenish the heat absorbed from the earth by the fluid in the collector pipe. It is important that the ground loop be absolutely watertight, since any leak in the system will be...

Solar Hot Air System Design

Solar Hot Air Design

Jim Myers on the roof with the two solar hot air collectors that AAA Solar installed for heating his home. Solar air collector systems are simpler and less expensive than solar water heating systems because air does not freeze or boil under any normal conditions on our planet. These systems don't require extraordinary chemical and control strategies associated with many liquid collector systems in harsh climates.

Bricht Day Solar Heater

Whenever the sun shines, heat energy builds up inside your attic. Even on cold winter days attics can produce air temperatures of 85 degrees or more. The Bright Day Solar Heater takes this free renewable solar heat from the peak of your attic and supplies it to the interior of your home. 512 589-8707 PO Box 92633, Austin,TX 78709

Simple Homemade Bimetallic Thermostat

Air collectors are primarily used for heating buildings. This makes sense, since buildings are usually filled with air. These systems are relatively new in the history of solar energy, first used around the 1950s. Air collector systems are also probably the most misunderstood of all solar energy applications, which led to the poor installation of thousands of systems more on that later in this article series . This is the first in a series of articles on the design, function, and installation...

As for the rest, since many people don't feel that they have the experience to undertake such a project, I plan to start construction of another RE home on our ridge as soon as possible, and it will be available for purchase. Renewable energy will be a condition of entry into the neighborhood. The hilltop sites around us are prime solar and wind locations, and I feel ever more motivation to make an environmental difference for the better. Nearly every day, new information surfaces about the...

Sanyo Modules More kWh per Watt

High efficiency HIT technology produces more energy per watt Sanyo modules outperform the competition because they maintain higher voltages at higher temperatures - which means more power and better performance Approximately 5 higher power than other crystalline modules - providing a higher rebate in some states per PTC ratings More power, less installation space required That's why SunWize GTS Grid Tie Systems rely on Sanyo modules. Prepackaged systems available from 1400 to 3000 watts. Visit...
