How much will the overall cost be for a home solar system?

The up-front cost of a typical home installation ranges from $16,200 to $21,400. Your bottom line will also be determined by maintenance costs and tax credits and other incentives. Your net savings will vary by region and by the amount of electricity you use.

What can I expect for maintenance costs?

Solar panels need to be maintained over time. This includes periodic cleaning and repairs. It is recommended that panels be cleaned twice annually at an average cost of $150 per cleaning. Any needed repairs will add to the cost. The combined costs of equipment and labor can range from $200 to as much as $3,000.11

When you own your system, you are responsible for the cost of maintenance and repairs. Alternatively, a Sunrun solar lease lets you only pay only for the power. We handle the maintenance ourselves so you don’t have to worry about it.

How can I take advantage of tax credits?

Tax credits and other incentives can help reduce your costs by thousands of dollars. The federal solar tax credit is one of the best solar incentives out there. Many states offer additional incentives that allow you to deduct a portion of your system’s cost from your state tax bill, similar to federal solar tax credit. Solar rebates are also available in some states. Consult with a tax professional to understand the credits you’re eligible for. With Sunrun, you can also set it and forget it when you lock in 25 years of affordable solar power with just one upfront payment. From paperwork to installation to maintenance, we take care of the rest.
