Frequently Asked Questions

The size, shape, and slope of your roof are also important factors to consider. Typically, solar panels perform best on south-facing roofs with a slope between 15 and 40 degrees, though other roofs may be suitable too. You should also consider the age of your roof and how long until it will need replacement.
It’s important to factor in how long solar panels typically last. The industry standard for most solar panels’ lifespans is 25 to 30 years. Most reputable manufacturers offer production warranties for 25 years or more.
According to a study from National Renewable Energy Laboratory (NREL), the average degradation rate is 0.50% across all solar panels. That means you could still expect your solar output to be about 89% of its original output after 25 years.
The quality of work put forth by your solar installer is the most important aspect of your solar installation. An inverter malfunction or dirty panels will be the least of your worries if your roof starts leaking or if you have poorly installed wiring.
Choosing a local solar company is a choice that can benefit your home, and your community, for many years to come. Local companies, provide high-quality products, first-class customer service and are deeply invested in their communities.
Solar panels pay for themselves over time by saving you money on electricity bills, and in some cases, earning you money through ongoing incentive payments. Solar panel payback time can range between 5 and 15 years in the United States, depending on where you live.
