Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone).

The optimal tilt angle for solar panels typically equals your location's latitude. For most of the continental United States, this means angles between 25-45 degrees.

To seal solar panel connections against water, you'll primarily use silicone-based sealants, butyl tape, or weatherproof junction boxes. Silicone sealants offer durability and UV resistance, while butyl tape provides flexibility for temperature changes.
