What would a hybrid system save you?

Enter your current electric bill and a bit about your home, and we'll estimate how much of your cooling costs the sun could cover. This is a planning estimate — your installer will confirm exact numbers at a site visit.

Comparing a fully installed hybrid system with panels against your annual savings
Estimates only, based on typical usage patterns for your region and system count. Actual savings depend on your roof, shading, insulation, and how the system is used. Ask your installer for numbers specific to your home.

How we estimate this

Share of your bill spent on cooling

We estimate the portion of your electric bill that comes from air conditioning based on how many systems you run, then scale up slightly for each additional system.

Sun hours where you live

Every region gets a different number of usable peak sun hours per day. More sun hours means the hybrid system can carry more of the compressor's load on DC power instead of grid power.

What "coverage" means

Coverage is the share of your cooling costs the solar panels can realistically carry through sunny hours, before the system falls back to grid power at night or on cloudy days.

Which way your roof faces

A south-facing roof gets the most direct sun and the best return. East, west, or mixed-facing roofs still work well but capture less sun overall, and north-facing roofs see the least.
