Enter your electricity bill and where you live to estimate the number of panels, system size, and roof space to offset your usage.
Modern residential panels are typically 380–450 W. A 100% offset aims to cover your full annual usage.
Actual panel count depends on your roof size, angle, and shading. Get matched with local installers and compare free quotes side by side.
Installing your own system for an RV, cabin, workshop, or off-grid home? Renogy sells complete kits — panels, a battery, a charge controller, and an inverter — sized from weekend setups to larger off-grid builds. It’s a go-to brand for DIY solar, and buying the kit together is simpler and cheaper than sourcing parts separately.
