Solar shingles are not a new invention but since Tesla has come out with their own version we have seen an increase in people inquiring about them. While I see it as a positive that solar is getting more publicity and more exposure on many media platforms I feel it is appropriate to address the benefits and drawbacks of a solar shingle installation compared to conventional panels.
Solar shingles have dual functionality. Not only do they protect your home from the elements but they can also help power your home. Given that it takes the place of your roof the most common time to install them would be either when building a new home or when it is time to replace your current roof. The complexity of the design leads to a higher installation cost and the lower efficiency of the built-in cells means that over time the total cost is also higher compared to regular panels.
If you have ever been up on your roof during the hot summer months you will notice that it is incredibly hot. Like any electrical system, solar performs better at cooler temperatures (this is why your laptop has built-in fans). Panels are installed on rails which allows air to flow under the array helping to keep them cool. Solar shingles are part of the roof and as such are at increased risk to thermally accelerated degradation further lowering their efficiency.
I think one of the reasons people are drawn towards solar shingles is because of the stigma surrounding panels that they are ugly. Without a doubt there are ugly systems installed in our area and like any industry there are good installers and bad installers. Bad installers leave rails exposed, wires hanging over the edges of roofs and poor electrical work. Cape Fear Solar Systems install the most attractive and most efficient panels on the market and with a customer base built up over the last decade we can show you over 400 installs that are carefully engineered to leave a sleek, clean finish.
In summary, solar shingles are a great concept but you cannot compare them to regular panels. Solar shingles are more expensive, less efficient and do not have the proven track record that conventional panels do.
