I have zero experience with this, so it's all bits and pieces of information I'm getting from what I find online. I'm not sure what solar panels are the best, or what to look for when buying. How did you decide and what brand are you using?
This is a reliable company that 's competitive and been in business for a long time: The Solar Biz. My friend lives next door to them in New Mexico, they're so far from the grid you can't even find it so everything is solar including their deep wells. I've seen all the work he's done on his own place, he can help you with design and engineering questions as well as sell you the stuff.
