Choosing an installer is one of the most important decisions in a solar project. The right questions help you compare offers fairly and avoid surprises later.
About the proposal
What exactly is included in the installation scope?
Which panel, inverter, and racking models are proposed?
What assumptions sit behind the production estimate?
What is excluded or charged separately?
About warranties
Ask for each warranty in writing. Equipment warranties come from manufacturers, while workmanship warranties come from the installer. Find out how long each lasts and who you contact if something goes wrong.
About permits and timing
Confirm who handles permits and utility applications, and ask for a realistic timeline. Approval steps often take longer than the physical installation.
About support
Ask what monitoring is provided and what happens if performance drops. Clear answers here are a good sign of a team that plans for the long term.
