Solar Panels, Kits, and Components: Build Your Own Power

This hub is about solar you build: panels, MPPT controllers, battery banks, and inverters, bought as matched kits (Renogy, Shop Solar Kits) or as components, mounted, wired, and expanded over time. Sizing is taught as arithmetic you can check, using NREL sun-hour data and honest efficiency factors.

Boundary, stated plainly: battery boxes you carry to an outlet and plug appliances into are power stations, and they live on our sister site, BackupPowerGuides. If it is built and mounted, it is here.
