Solar panels capture the sun’s radiation and transform it into energy. This captured energy can be used to power your home, much like regular energy sources. Solar panels are often made using photovoltaic (PV) or concentrating solar-thermal power (CSP) technologies. PV panels are used most often for residential homes. The PV material absorbs sunlight, creating electrical charges to flow within the panels due to their internal electrical field. This electricity is then channeled into the building, allowing the transformed energy to power the building.

Americans save an average of $1,500, give or take, on their monthly electric bill when they switch to solar. Over the course of 25 years, this can add up to $37,500 in total savings. But know that the savings that accompany this energy alternative differ from home to home. From local electricity grid prices to the type of panels you choose, how many are installed, even the weather in your area impacts how much your solar panels help you save every month. Plus, you can claim the investment tax credit (ITC). This residential solar panel tax credit gives homeowners 30% of their installation costs.

Solar panels may cost $16,000 to $21,000. Across the United States, a new solar system costs $2.94 per watt on average. Of course, the type of solar panels, their wattage, and where you live have a significant impact on the final price tag. Homeowners in California or Washington, D.C. are more likely to pay more than a homeowner in North Carolina or Kentucky. Tax incentives, loans, solar leases, or power purchase agreements (PPAs) are all ways to help lower the initial price tag of buying and installing panels on your property.

Often, a solar system supports the home’s electric system by supplying only a portion of the overall energy supply. Depending on your current electricity system, you may need only a few panels or as many as 30 if your goal is to power your entire home with solar energy. Talking with a solar contractor is the best way to better understand your home’s current energy consumption and how you can choose the right number of panels to reduce your overall energy costs.

It depends on where you live and your home’s dependency on solar energy. Homes that rely entirely on green energy sources may benefit from having a solar battery as back-up. That way the house can receive electricity in the case the panels malfunction or need to be replaced. When looking for the right solar solution, ask your contractor for their recommendation. They will be able to make suggestions that are tailored to your situation. If they think you could benefit from a solar battery, they can point you towards the best options.

Yes, you can install solar panels on your own. However, be prepared for the hassle that comes with the project! If you’re planning on putting the panels on your roof, it’s crucial to ensure the roof is in good condition. Working with a solar contractor means that they will appraise the building's roof and help you fix your roof to accommodate the panels. The actual panel installation that follows requires some complex electrical wiring. If you’re not comfortable with your DIY electricity skills or spending extended periods of time on the roof, then it’s best to hire a professional.
