What are Solar Shingles?
Solar shingles are a relatively new technology designed to look like ordinary asphalt shingles on your roof. They protect your roof and have the same durability and flexibility as regular shingles, while harnessing the sun’s solar energy to generate power for your home. Each solar shingle will produce between 13 and 63 watts of energy, depending on the brand of solar roof shingles. Solar shingles are lightweight and easy to install and just like ordinary shingles, they are designed to withstand rain, wind, and hail.
Solar Shingles vs Solar Panels
If you were trying to decide between installing solar shingles or installing traditional solar panels on your roof, here are a few advantages and disadvantages to consider beforehand. The benefits of solar shingles include being more aesthetically pleasing than bulky solar panels, being more cost effective (if you are replacing your roof anyway – 10% to 15% more cost effective per watt of solar energy), and are able to be removed and reinstalled if you were to move homes.
The disadvantages of solar shingles is they can sometimes be less energy efficient than regular solar panels, you’ll need a particular roof slope with high sunlight exposure, lifespan is less, many solar installers do not offer solar shingles yet as they are still growing in popularity. Traditional solar panels can also produce more energy per watt in comparison to the cost of solar installation.
Solar Shingles Cost
The average roofing installation price for a solar shingle roof costs anywhere between $60,000 to $75,000 depending on the slope, pitch, and size of your roof. You can expect to pay $21 to $25 per sq. foot or $2,100 to $2,500 per square installed on a standard sized single story home. Costs will vary depending on local solar roof contractor’s pricing.

How many solar shingles do you need?
The number of BIPV shingles it would take to power your entire home depends upon the size of your house and your typical energy usage, but even installing a few can help out. It is not necessary to replace your entire roof as you can integrate solar shingles into your existing roof. If your roof is in need of an overhaul anyway though, replacing your roof is not a bed investment. According to the most recent Cost vs. Value report, replacing the roof on your home can have an an ROI of 71.6%. Additionally, recent Department of Energy backed studies have demonstrated that homebuyers are willing to pay a premium for homes with solar roofing features, up to $15,000 more.
How long do solar shingles last?
The average solar panel lasts from 20 to 30 years at maximum energy output. Your solar panel shingles will continue to create solar power after the 20 year mark but just like an older cell phone battery they may not produce energy at maximum capacity as they did before.
