Solar Proposal

A solar proposal (also called a solar quote) is a detailed document from a solar installer that outlines the recommended system design, expected performance, pricing, financing options, and projected savings for your specific home. It is the primary tool for evaluating and comparing solar offers.

A thorough solar proposal should include: system size (kW), number and model of panels, inverter type and model, mounting method, estimated annual energy production (kWh), projected solar offset percentage, total system cost (gross and net after incentives), itemized breakdown of costs (equipment, labor, permits, etc.), available financing options with monthly payment estimates, projected electricity savings over 25 years, estimated payback period and ROI, warranty coverage details, and a preliminary system layout showing panel placement on your roof. Quality proposals are based on actual site data (from a site survey or satellite imagery analysis) and use your real utility bills to project savings. When comparing proposals from different installers, ensure you’re comparing equivalent system sizes, similar equipment quality, and the same assumptions for electricity rate escalation and production estimates. Getting at least three proposals is recommended to ensure competitive pricing and find the best fit.
