It's always a pleasure doing business with these guys, you get a great product, new or used at a great price ! And the service is excellent to boot, if it's a solar panel then it's delivered to you door by a first rate carrier who's a small guy company so it's the ultimate in personal service. For a whole package you can't beat these guys !
Bought an off grid kit, Had some technical questions on what to buy, reply in 24hrs
