1. Our main array, providing power for a 12vdc SHURflo pump, some 12vdc appliances (tv / dvd player / phone chargers), and interior LED lighting. 2. Our secondary array, solely to provide LED perimeter lighting around the house. It was tiresome going to bed and waking up in the dark. An easy fix, though. 3. Our small farm house also has a total of 55 m2 (592 ft2) of rainwater collection area, to collect the water for household use, showers, drinking, etc. The water is then routed to a single 10cm (4in) x 3 meters (10ft) PVC tube first flush system. After flushing the roof, the water is then routed to five (5) 1200 liters storage tanks (1585 gallons, total) piped together, with ball valves between the tanks. Each tank can be individually isolated from the system for repair / replacement. From the tanks, which are located adjacent to the house, the water is piped through a meter (for me to monitor our usage), a filter system, the pump, and then to the various spigots and water outlets. I know it doesn't sound like much. But, during our rainy season here, I could probably fill ten times that many tanks from the roof collection system. I am going to be expanding the system, and replacing the current tanks with two 10,000 liters tanks. That will increase our water storage capacity to almost 5,300 gallons, using just those two tanks. The SHURflo pump provides the farm with a complete pressurized water system, and a western toilet and shower. Sorry folks. I tried to use one of those composting toilets. It is NOT for me. I like feeling fresh after my morning meetings. I can live a pretty simple life. But, my toilet is going to be a proper flushing toilet, pressurized water and a bum gun to insure that. (In SE Asia, most people do not use toilet paper.) On a positive note, my toilet uses less than 3 liters on every flush. EDIT: I tried to add tags, but the system did not allow me to do so.
