Most panels include solar cells, tempered glass, encapsulant, a backsheet, a metal frame, an inverter, and a junction box. In the sections ahead, we'll walk through each part so you can better understand how solar panels work and why they're built to last for decades.
A photovoltaic system with storage consists of solar panels, an inverter (which converts energy from direct current to alternating current), a management system, and, indeed, batteries.
