How Solar Shingles Protect Your Home and Save EnergyAdd to My Luxx Living
Solar shingles are changing the way the world looks at roofs, simply by making them work harder. Instead of merely lying passively on your house, these shingles generate electricity from the sun’s rays to power your life — while still keeping everything inside protected from the elements. And between making electricity, saving you money and increasing your home’s value, they’re one of the smartest investments you can make for your home.
When sunlight hits the solar cells in the shingles, photons are absorbed, releasing electrons and creating an electrical current. The electricity enters your home through a wire connected to the home’s solar inverter. The solar inverter converts the direct current (DC) to a usable alternating current (AC), which is fed into the electrical distribution panel to power your home. When a monitoring system is integrated, you can see how much energy your system is creating and your home is using as well as the savings you’re generating.
Each array is custom designed. A typical home may require approximately 350 solar shingles to offset 40 percent to 60 percent of the electric utility bill.
On average, systems vary from 1 kW to 10 kW. System size is dependent on roof layout and available roof surface area. Each system is customized for your roof and goals.
Some utility companies require houses to have a second meter to measure solar energy production, while others install a single meter on homes that turns forward as energy is being consumed, and backward as it’s being created. All systems that are tied to the grid require an interconnection agreement between the system owner and the utility company.
Unlike a traditional roof, the solar shingles create value every day, says Cazeault. He estimates that for every one dollar invested in the shingles will derive $4 in energy savings. These include a 30-percent federal tax credit and powerful state and local utility company incentives.
The shingles themselves have earned seven certifications for both performance and safety, which means they’ve been tested, retested, validated and certified to stand up to the worst of the worst — including 110 mph winds and hail as large as one inch, he said.
They’ve been designed to be maintenance free, with a 20-year warranty. In areas where dust or debris can build up on the shingles, occasional washing with a garden hose will improve the array’s performance. The solar inverter may require maintenance or replacement after 10–15 years.
