Solar Panel Cost
Estimate your solar installation, then verify the proposal.
A useful solar installation estimate should consider system size, panel tier, battery needs, roof complexity, incentives, and local market factors. A useful proposal review should also verify scope, allowances, warranty, payment terms, permits, and change-order language.
What to check before signing a project proposal
- Total contract amount and whether it is actually construction cost or a professional-services fee.
- Detailed scope, materials, labor, cleanup, exclusions, and permit responsibility.
- Allowances, unit prices, and what happens when hidden conditions appear.
- Written change-order approval process.
- Workmanship or labor warranty length and what it covers.
