Transitioning into a zero-carbon future will undoubtedly require significant changes to generate the energy we need to power our homes. Though commercial solar power is expected to grow around 2 GW per year from 2021-2025, household or residential solar power is another major renewable energy revolution player. For most people, residential solar power is about placing solar panels on your roof, garage, or other areas where you receive abundant amounts of sun. The number of residential solar systems installed is increasing rapidly. In 2010, new systems accounted for only about 250 MWdc. Fast forward to 2020, and new installations added over 3,000 MWdc of solar power to the energy mix. 

The advantages are apparent. With solar at home, you have the exciting opportunity to harvest energy to power your home, cut your electricity bills, and reduce your household carbon footprint. However, as technology has developed, different options to take advantage of the free and abundant solar energy are beginning to appear. For homeowners whose roofs are shaded or poorly oriented, community solar programs are continuing to grow. Even if you do not own a home, people in many regions around North America can purchase green power for their rental, apartment, or office.

Today, companies are taking different approaches towards developing residential solar PV systems that meet homeowner's energy demands while also providing aesthetic qualities for the house. Solar roofing or shingles are an investment worth exploring for those who are turned off at the aesthetics of large solar panels. With solar roofing, the solar array is an integrated part of the roof's protective outer layer. This feature can make the solar array less obtrusive and save on other roofing materials.

Below, we will explain some of the current developments in solar roofing technology and explain the advantages and drawbacks of this exciting development in residential solar PV systems.
