Hey everyone! I've been considering getting solar panels installed on my roof, but I'm a bit in the dark about how pricing works. For a panel rated at 220W, I'm curious if the cost is primarily based on the wattage, the size of the panel, or some other factors. Also, are there any hidden costs that I should watch out for? I want to avoid getting ripped off, so I'm looking for advice on what specific questions I should be asking my installer.

Typically, solar panel pricing is calculated on a cost-per-watt basis rather than per individual panel. Instead of just focusing on the 220W rating, you should ask about the total system size measured in kW (like 6kW or 10kW) and the total cost before any incentives. Generally, a fair price falls around $2.30 to $3.00 per watt before tax credits, depending on the quality of the equipment and your location. Don't forget to check for extra expenses like upgrading your main power panel, trenching costs if you're going ground mount, or any necessary roofing repairs. Also, keep an eye out for low monthly payment options that might lead to balloon payments later on. Ensure you're getting a solid warranty—aim for at least 25 years on both the panels and inverters. It’s important to request a detailed breakdown from your installer including the system size, brands used, warranties, and expected annual power production.
Thanks for the insights! I plan to install around 24 panels at 220W each, giving me about 5200W. I'm not connecting them to the grid, just using some lithium batteries. My roof is new and already inspected, so no upgrades needed there. Sounds like my main cost will just be the installation of those panels. Is there anything else I should be on the lookout for?
