Solar Power Update With several posts regarding the installation of solar power at Roy Creek Ranch, one might wonder whether or not it worked. Read on and learn about our experience in an emergency situation. The Solar Array is enlarged … Continue reading →
Upgrading a Solar Power System It was time to upgrade the solar power system installed for the shop almost two years ago. I’ve been happy with original system, but it needed expansion as soon as funding permitted. I also wanted … Continue reading →
In a previous post, we selected a site, cleared trees and installed foundations. Now we were ready for framing. There were four 8-inch concrete piers defining the four corners of the array. The plan was to mount two 10-foot 4-by-4 … Continue reading →
The Solar Powered Rainwater Project began about eight months ago, although one might argue it is the culmination of my rainwater system dreams beginning in 2002.

The solar-powered rainwater system was complete — except for more panels, and a cable to isolate the rainwater power from the rest of the system. Construction on the rainwater system began in 2002, when I trenched the various wires and pipes into the ground. I needed power for the rainwater system, and tapped into an underground wire originally intended to supply power to the well.

With all the parts in stock, it was time to assemble the whole Solar Powered Rainwater Project. I cleaned out a space in the garden shed, and added plywood to the wall for attaching the various components. We would be mounting the inverter/charge controller, solar panel combiner/breakers, A/C transfer switch and related wiring.

You may recall from an earlier post that the Solar Powered Rainwater Project requires substantial battery storage. In our original calculations, we decided we would need 15,796 watt/hours of storage to provide three days of autonomy (or days without sun).

It’s been a while since I reported on the Solar Powered Rainwater Project. Since that early-April post, I’ve been gathering the rest of the parts, and we took our annual trip to the Red Power Roundup — this year at the Iowa State Fair in Des Moines. The biggest part of the delay was waiting for the inverter/charge controller. I wasn’t thrilled with the delivery delay on the device, but it turned out well in the end.

The new 250-watt solar panels arrived very quickly. I was eager to install them, but they were just a bit larger than I could handle safely on the garden shed roof. Fortunately, I didn’t have too wait long, and my neighbor Jason was available a few days later.

Major equipment purchase done, it’s time to think about the installation. The solar panels will be arriving in a day or two, and I plan to install them right away. Solar panels produce maximum power when the sun is perpendicular to … Continue reading →
