Solar shingles have been in the works for decades, but only now are they making their way into homes. The concept was first invented by a company called Tesla. GAF Energy (and CertainTeed) are also working with the same technology. Some companies even attempt to make solar roofing shingles that will stick to your roof.
Tesla was the original company to produce solar shingles
Solar shingles is a relatively new product. Tesla was the first company that did this. They introduced a solar roof system in 2015 that blends in with homes' regular asphalt roofing shingles. Since then, other companies, including Dow Chemical Company and BP Solar, have attempted to create solar shingles but have not yet achieved the level of efficiency required for residential rooftop solar panels.
Tesla's solar shingles are made up of both active and inactive shingles. The homeowner can enjoy all the benefits of solar without having to sacrifice aesthetics. However, the solar shingles are more expensive than the traditional solar panels, so they are not a cheap option for homeowners.
Prices
Solar shingles are priced according to how much power they produce. Solar shingles can produce between 13 and 63 watts depending on their efficiency. Solar shingles with low wattage require more roof area or more shingles. There are two types if solar shingles: silicon solar and thin film solar. Thin film solar roofs are cheaper than all other types. The efficiency of silicon solar shingles is similar to that of regular PV modules but they are much more expensive than thin film solar shingles.
Solar shingles prices vary greatly from one manufacturer to the next. Solar shingles typically cost between $20-25 per square foot. Cost of solar roofs for a 2,000 sq. foot roof is $45,000
Efficiency
Solar shingles harness solar energy to produce electricity. When sunlight hits solar shingles, electrons are drawn to holes in the roof that are positively or negatively charged. This causes DC current. The DC current is converted by an inverter to alternating power. This power is then stored. It can be used as a power source for your home or office.
There are many options for making solar shingles. While some use thin-film technologies, most use silicon-based solar cells. These shingles are typically easier to install that traditional solar panels. These shingles can also be blended in with existing roof materials and are more flexible.
Lifespan
Solar shingles are an increasingly popular option for new roofs in many parts. They offer many benefits including the ability of lasting longer than typical roofs. They contribute to the increase in property value. A number of studies have shown that solar roofs can increase the property's value up to $15,000
Solar shingles can last 30 years but their life expectancy varies. Every manufacturer offers a different warranty on the material. The weather can impact the life expectancy and durability of solar-shingles. Weather conditions can cause damage to the panels and decrease the lifespan of solar-shingles.
Permits
When deciding to install solar shingles on your roof, the first step is acquiring the proper permits. There are several factors that will determine which permit type is needed. Some cases require special clearance from the local fire department around the solar array. Others may need a historic commission permit.
It can take several days to apply for a solar permit. You can save time by hiring third-party service providers to handle the paperwork. The typical application is 10 to 15 page long. Once the application is submitted, the utility or AHJ will review it. If there are any issues, they will notify you. If your application is rejected, you can resubmit it. Often, permits take a few days, but it can take as long as a week.
