Trina is a reliable option that’ll fit well in a budget. Solaria makes good panels known for their classy, modern appearance. 

Whatever you choose, keep in mind that the newest and flashiest models will become progressively outdated with each year’s more advanced releases. Rather than spending a lot of money trying to keep up with the latest and greatest for only slight improvements in performance, a better long-term approach might be to choose less expensive panels that still give you the power you need.
