Powering Your Future

We need to upgrade the solar-electric system for an off-grid home. The existing array consists of two 80-watt modules rated at 21.8 Voc (open-circuit voltage) and 4.85 Isc (short-circuit current), and two 120-watt modules rated at 21.5 Voc and 7.45 Isc. The owners would like to add one 175-watt module rated at 44.4 Voc and 5.3 Isc. The array sits on a hill that's 160 feet from the batteries and inverter. We put each 80-watt module in series with one 120-watt module and wired those strings to...

Solar Water Systems

By John Patterson & Suzanne Olsen No space for a traditional two-tank solar hot water system No problem. Single-tank solar water heating systems offer great performance and high efficiency, all in one small footprint. A single-tank solar water heating system combines solar preheated water and backup heating into one tank, in contrast to a typical two-tank system, which separates these functions. Both singletank and two-tank solar hot water heating systems can save 55 to 85 on water heating...

I have an update to my conversion story. I found that my fears of exceeding the 400-amp battery current were unfounded. Canadian EV contacted me and suggested that I simply reprogram the Zilla controller for 550 battery amps. At that level, they felt there was no risk in overheating the...

It was about two years ago when my son, Alec, and I opened a solar power experiment kit that I bought for 10 from a local hobby shop. Since he loves his International Space Station replica, complete with blue solar-electric arrays, I figured his curious mind might like to see solar power up close. We found a sunny spot in the backyard and laid out all the pieces a small photovoltaic module, wiring, and a tiny DC motor with plastic fan blades. After a few seconds in the sun, the tiny fan started...

Department of Energy, 47 of the average home's energy use is for heat either domestic hot water or space heating. Using specially designed collectors, solar hot water SHW systems collect the sun's heat and store it in water. In turn, this stored energy is tapped for domestic uses like showers, laundry, dish washing, or even heating your home. Installing a solar hot water system represents one of the best renewable energy RE investments that the average homeowner can make....
