Price of electricity generation solar home system

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.

Below is a breakdown of pricing for different home sizes to help you plan your investment. A 5KW solar panel system is typically sufficient for modest households with minimal energy requirements. The average cost for such a system is between $12,000 and $16,000.

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.

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.

For reference, the national average cost of solar panels is $3.03 per watt. Solar rebates help make solar more affordable by directly lowering the upfront cost of a solar installation. If you have access to solar rebates, consider yourself lucky! They are few and far between these days.

Depending on the project, an electrical panel upgrade for solar could cost between $2,000 and $3,000. If your solar system uses a string inverter, it may need to be replaced. String inverters generally last between 10 and 12 years, while solar panels last for 25 years or more. Getting a new string inverter could cost about $1,500.
