Cost Structure and Financing Options
Installation quotes should break down equipment, labor, permits, and any additional services like monitoring. Look for transparent pricing and ask whether the company offers financing, power‑purchase agreements, or lease options that match your budget and cash‑flow preferences.
Quality of Equipment and Warranty Coverage
Reputable installers partner with established manufacturers and can offer product warranties of 20‑25 years plus a workmanship guarantee of 10 years. Compare panel efficiency ratings, temperature coefficients, and inverter warranties to gauge long‑term performance.
Service and Support Timeline
Ask for a detailed project schedule that includes site assessment, permitting, installation, inspection, and activation. A good installer provides a single point of contact, post‑installation monitoring, and a clear process for warranty claims.
