Before you hire a solar installer
- Ask for a production estimate for your roof (kWh per year) and how shading was measured.
- Ask which panels and inverter they use, and who backs the warranty if the company closes.
- Ask how your utility credits extra power you send to the grid, and whether a battery makes sense for you.
