Estimate only. A free site assessment sizes your system properly against your actual usage, roof and budget.

This tool gives a rough, indicative starting point only — it is not a quote. The right system depends on your actual usage pattern, roof, appliances and budget, which a free site assessment confirms. SolarGuide is an independent referral partner; Alumo supplies, installs, finances and warrants the systems, and all pricing is subject to a site assessment and credit approval.
