Solar Powered Rainwater Project – Completed?

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.

Solar Power Rainwater System – More Panels!

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.

Solar Powered Rainwater Project – Final Assembly

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.

Solar Powered Rainwater Project – Batteries

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).

Solar Powered Rainwater Project – Panels, Batteries and Inverters — Oh My!

In a previous Project post, we determined our power needs – 1300 watt-hours per day to pump water. Now we can calculate the battery bank capacity,  solar panel wattage, and inverter capacity needed for our installation. Let’s start with the panel … Continue reading
