The Chinese are now flooding our market with solar panels at less than a dollar a watt retail. search online or try Buy Solar Panels Online for Home | Solar Power Inverter | Residential Solar Panel at Wholesale Price or my favorite : simpleray,com. use golf cart batteries and get a maximum power point tracking charge controller (MPPT) an inverter to run ac loads and if you have a well, a 120 to 240 volt 2kva transformer to keep the water flowing. Start with a 12V system and get some 12 volt LED lights. I stayed with 12V while most people now use 24 or 48V systems.
