Technical FAQs 4

How much do commercial solar panels cost?

Generally, installing solar panels on businesses costs a bit less per watt because the systems are larger, but the total costs will be higher. In 2025, the average cost for commercial solar panels is just about $2.00 per watt. There is a lot to consider when figuring out how much you’ll spend on a solar installation.

How much does a solar system cost?

On average, solar panels cost about $9.34 per square foot of your home’s total living space. This means a solar system costs about $13,075 for a 2,000-square-foot house, including the solar tax credit. Note: Using square footage to estimate home solar system costs only offers a rough guide and will not provide a truly accurate price.

Should you install a solar energy system on your roof?

When you install a solar energy system, you’re getting more than just solar panels on your roof. Multiple pieces of equipment, such as racking, wiring, and inverters, must be installed so the solar panels can power your home.

How much do solar panels cost if I do a DIY installation?

A DIY solar installation will cost somewhere between $9,000 and $15,000, depending on the system size and equipment used. When you install solar yourself, you don’t have to pay labor costs, customer acquisition costs, or installer profit margins.
