[Closed] How to choose solar products?

You can buy cheap less efficient panels and buy more of them. Or better, more efficient panels and less of them. We're in the process of getting panels and an inverter but we're in Oz. Don't expect them to save you heaps if you're all out in the day, they don't store the power, unless you're going to buy one of those Tesla units. A lot of people here expect massive savings but its all down to how you use the power. Like setting dishwashers, washing machines to be on while you're at work.

People here really rate the German panels. We're still looking into it.
