“Solar Energy World helped me lower my energy costs while reducing my carbon footprint. It was a win-win for me.”

It all started in February 2011, when Denise decided to go solar. With a small roof space yet a lofty goal she choose SunPower signature all-black solar panels – the most efficient solar panels on the market today.

While researching, Denise learned about the MD solar incentives that help MD homeowners save on their solar panel installation. And that was a turning point for her. After speaking to several solar integrators, Denise choose Solar Energy World, for its professional service and knowledge in the industry.

Denise has discovered some additional and unexpected benefits after installation. The solar panels help protect the roof as well as help insulate the home. And, with skyrocketing energy prices, not having an energy bill is a big plus.

The 3.6kW solar PV system is equivalent to preventing 1.1 tons of waste being sent to the landfill.
