Solar Panels questions, answered by experts

DIY solar panel installations are hard to manage by yourself. You’ll likely need some help or prior experience to make the project worth the effort.

Solar roofing shingles may qualify for significant federal tax incentives through programs like the Residential Clean Energy Credit, which offers up to 30% of installation costs through 2032. State and local governments often provide additional credits, and utility companies may offer further rebates or net metering programs, depending on the state. Just look into the qualification requirements beforehand because installation, documentation, and technical standards can impact eligibility. Consult the current guidelines and a tax professional to maximize available benefits.

The best solar-panel mounting system will depend on your property layout, but you’ll typically want to try for south-facing panels to get the most sun. Roof mounting and wall mounting are both popular, but if your well setup is far away from buildings and other structures you can also set up a freestanding aluminum frame to mount your panels.

The best way to save money on solar panels is to take advantage of federal and state solar incentives. For example, the solar investment tax credit (ITC) offered by the federal government can save 30% of your total—if you can take the entire credit, which is based on income taxes owed—or an average of around $9,000. You can check the Database of State Incentives for Renewables and Efficiency (DSIRE) for state and local incentives that could save you even more.

Solar panels can pay for themselves in five to 15 years, depending on the cost of your system, how much energy it generates, whether you qualify for incentives or power buybacks, and the price of energy in your area. Solar panels pay for themselves over time as they lower electricity bills, so it will take time to recoup your initial investment. However, the longer you have your system, the more money you can save and earn.
