Solar Installation Benefits


Solar provides a number of great benefits to homeowners and business owners alike. Some of the benefits of solar include financial savings, a reduction in your carbon footprint and less reliance on utility companies. The federal government currently has tax credit incentives that are making solar roofing installations more affordable. Another awesome solar incentive is a program offered by PG&E and some other utility companies that allow the selling and buying of energy. This program is often referred to as NEM (Net Energy Metering).

Quick Payback Period

One of the main concerns Simply Solar hears from customers is the cost of going solar. Contrary to popular belief, solar can oftentimes be more affordable than your current electric bill. Simply Solar always does its best to make sure its clients can see a ROI (return on investment), within a 5-7 year period. For Robert and Patti this mark is closer to year six. After year six, their savings will substantially increase for years to come.

Increased Property Value

Solar roofing installation also increases a home or business’s property value immediately. Solar panel systems will often increase the property value more than the system was originally worth. Most systems will increase the value by $6,000 times the system’s size. For Robert and Patti, this could mean close to $35,000 in increased property value while they purchased the system at below $15,000 net cost!


Most homeowners are skeptical of solar at the beginning but oftentimes they are not fully aware of all the potential savings; not only the current savings offered but the future savings as electricity rates continue to rise each year. Over the lifetime of a solar system, homeowners see substantial savings and create a cleaner environment for them and generations to come.

Environmental Impact

Solar panel systems are a special product and investment. It not only benefits the homeowners and users but also positively affect the planet. By switching to solar energy Robert and Patti have reduced their carbon footprint, dramatically. Over the next 25 years, their solar system will provide an environmental impact equivalent to the planting of 5,710 trees, the reduction of 186,888 miles driven and the elimination of 256 people’s trash.
