Residential systems are designed for typical home usage, while commercial systems handle much larger energy demands of offices, factories, and retail spaces.
Residential installations focus on aesthetics and simplicity. Commercial projects prioritize maximum output with advanced mounting systems and often require more complex permitting.
Commercial systems benefit from economies of scale, resulting in lower per-watt costs and faster ROI.
Both qualify for federal incentives, but commercial projects can take advantage of additional tax benefits like accelerated depreciation.
