Buy solar panels from a reputable retailer like Home Depot, Lowe's, or SunPower. These companies sell high-quality panels that have been tested and certified by independent laboratories. The biggest benefit of buying from a retailer is that you can get a discount on your purchase.
You can find local solar installers who will install your panels for you, usually for a price that's lower than what you would pay at a retailer. However, you may not be able to get a discount on your purchase if you go this route. If you want to know about pv solar panels in Hove, then you may pop over to this website.
