Welcome to skoolie! It is great to see so much enthusiasm!
Tell us exactly what you want to run with solar & that will give us something to work on to help you to decide on what you need to buy for power. I have some really good links to help you to calculate what you will need & they also explain in detail all about solar power.
We are in the process of setting up solar in our Thomas to run our internet business off grid. We have a Xantrex 1000 watt sine-wave inverter, a charge controller & we just bought (3) 90 watt panels. We are buying our AGM battery bank this week but I am still unsure what AmpHour batteries we want to purchase...
Put this in your favorites, will come in handy...be sure to check out the other links on the site also.
