Four Model ASP390M Solar Panels for sale
You will want to buy the following things on E-Bay to complete this system:
1) Solar charge controller. Search E-Bay for "60A 1500w mppt solar charge controller." The "Stand-Alone" brand has worked well with these panels. These cost around $190 and are well documented.
2) Power inverter. Search E-Bay for "1500W 12 inverter." The PSW series has worked well for me, and was about $190.
3) Walmart sells trolling deep-cycle 12V batteries for about $99 each. They have a two year warranty, and you can use as many in parallel as you need. I use the Everstart MAXX, which has good customer ratings and have served me well.
This system has run a 5000 BTU/hr air conditioner in my home, which cooled a 20 x 20 room space on the south side of my home in Texas.
If you want more cooling power, I also have a 3000W system which can run a 7000 BTU/hr air conditioner and can cool a 30 x 20 room space in a hot climate.
BEWARE OF UNDERSIZED SOLAR KITS!!! :The startup current for running an air conditioner is enormous, so you will want to have your solar system sized properly so that it will work. These panels have worked with the air conditioner sizes I have mentioned. Please do some homework on this before purchasing a cheap system that won't work for you!!! (Yes... this happens all the time!!...)
If you install the panels on the ground (much better than on your roof!), you can adjust them and monitor them very easily. I use four 2x4s to mount these panels in my yard - no holes need to be drilled in the panel.
