Photovoltaic (PV) systems convert sunlight into electricity, acting as power generators. Think of PV as a water pump and ESS as a reservoir – one creates resources, the other.

Generators create power on demand by burning fuel (gasoline, propane, or diesel), while power stations store energy in lithium-ion or LiFePO4 batteries, drawing from solar panels or wall outlets. This difference impacts everything from noise levels to maintenance needs.
BESS deployments generally fall into two categories: behind-the-meter (BTM) and front-of-the-meter (FTM). While BTM systems are located on the consumer's side and primarily serve onsite loads, FTM systems are utility-facing, connected directly to the grid and serve broader grid.
The best panels typically offer efficiency ratings above 20%, annual degradation rates below 0. 5%, and come backed by comprehensive warranties from financially stable manufacturers.
