According to the National Renewable Energy Laboratory (NREL) in 2021, the average cost of residential solar systems ranges from $15,000 to $30,000 before incentives.

Energy savings: Solar systems reduce electricity bills by generating power from sunlight. A study by the Solar Energy Industries Association (SEIA) in 2022 found that homeowners typically save between $10,000 and $30,000 over the lifetime of a solar system, depending on their local utility rates and energy consumption.

Government incentives: Local, state, and federal incentives can significantly lower initial costs. For example, the Federal Investment Tax Credit (ITC) allows homeowners to deduct 26% of their solar system’s cost from their federal taxes, as reported by the U.S. Department of Energy (DOE) in 2020.

System lifespan: Solar panels generally have a lifespan of about 25 to 30 years, while battery systems vary from 5 to 15 years. According to the Solar Foundation’s National Solar Jobs Census (2021), many solar systems maintain a performance ratio of 80% or higher even after 25 years, which contributes to ongoing energy savings.

Performance monitoring: Regularly monitoring the system’s performance ensures optimal functioning and can help identify any issues that affect ROI. Studies show that systems maintained well can yield a higher return over time.

By analyzing these factors, homeowners can compute their ROI by comparing the total expected savings to the initial investment over the system’s lifespan. This comprehensive assessment helps determine the financial viability of investing in solar and battery systems.
