I think you're going to have to change your pricing model / plan of attack when it comes to selling in BTC. You need smaller kit. I doubt you'll be able to sell installation given who the current users of btc are.
Personally I might buy some product if you ever accept bitcoin - but I'd want it to be somewhat modular where I can choose the wattage I need and set it all up myself.
Honestly, you'd probably do better simply shipping all the parts of a panel for some lower price and letting people buy as many or few as they need.
AKA in this community, if we need solar we just buy b-grade cells for a buck a watt and assemble ourselves =P
Ha, point taken, thank you. Luckily, we can sell any of the components separately. The example I used was for a whole system being completely installed--if someone just wants to buy a factory made panel we sell those for around a buck a watt anyway, plus freight.
I think you are absolutely correct about starting with component sales (panels, batteries, inverters, etc.). I may have been overly optimistic to think someone would be willing to purchase a whole solar system with BTC right away

. Plus I have a small post count and am a complete unknown to everyone on here. Earning positive feedback from members by completing hassle-free transactions will help build my credibility with everyone. As I said in my initial post, escrow would be welcomed.
As far as putting together a solar panel from b-grade cells, I've looked into doing that in the past as a weekend project, but the pricing of cells, plus getting a soldering iron and solder, plus the wood or aluminum to build a frame, plus the plexiglass (or whatever) cover to protect the cells, plus the wire and special outdoor waterproof connectors--it was easier and less expensive to just buy a whole panel.
