For example, New Mexico offers the Solar Market Development Tax Credit that gives you up to 10% or not more than $6,000 on your solar equipment.

Utility Company Rebates

Aside from government incentives, many utility companies also offer rebates to customers who invest in solar energy systems. This can further cushion the financial impact, making the overall investment more appealing.

Financial Benefits: Are Solar Systems Worth It?

Immediate Benefits

Lower Electricity Bills: One immediate benefit of installing a solar system is the reduction in your monthly electricity bills. In some instances, the electricity could even be free depending on the size of your system and your electricity needs.

‍Excess Electricity Sell-Back: When your solar panels produce more power than you consume, you can sell this excess power back to the grid. These credits can be used to cover the electricity bill for the energy you use from the grid when the panels aren’t producing—such as during the night.

Increased Property Value: A solar system doesn’t just save you money in the short term; it also adds value to your property. A study by Zillow found that homes with solar panels sell for about 4.1% more compared to those without.

Long-Term Financial Calculations

‍Lifespan Savings

When considering whether solar power is worth the investment, it's crucial to look at the long-term financial benefits. Over the lifetime of a typical solar system, which can last 25-30 years, homeowners can save tens of thousands of dollars on electricity bills. The exact savings depend on a variety of factors such as your geographical location, solar system size, and electricity cost.

Payback Period

The payback period refers to the time it takes for your initial investment to be recouped through electricity savings. Depending on the cost of electricity in your area and the efficiency of your solar installation, the payback period can be anywhere from 5 to 12 years. Sunny California, for example, has an average payback period of less than 6 years. Is solar worth it in other states? Absolutely! Regardless of which state you live in, the solar system always pays for itself through savings if everything is done wisely.
