I think the best thing to do is to go to a solar panel retailer and supplier site such as https://www.searchingindustrial.com/media/4211/in-conversation-with-lumin-smart-grids-leading-the-way-to-clean-energy to find what you're really looking for. Here consultants will help you choose the most attractive option. And you will also see for yourself what range of panels is currently on sale. My wife was initially categorically against installing such panels - she said it was a waste of money and did not believe me. But now we are rich.
