Solar Panel Costs: What Changes the Price

What changes the price

• System size, in kilowatts
• Panel, inverter and battery choice
• Roof type and the work needed
• Where you live, and local labor and permit costs
• Incentives and utility rules

How to compare quotes

Ask each company for the total price, the equipment models, the warranty terms and who handles permits. Put the quotes side by side and compare like with like.

Questions to ask every installer

• What is the total price, and what is included?
• Which panels and inverter will you use?
• What warranties do I get, and who honors them?
• Who handles permits and the utility paperwork?
• How long have you installed systems in my area?
