Asphalt is the most common type of shingle used on housing and is also the best roof for solar panels. These shingles are made from a fiberglass or cellulose type of mat that is very flexible and durable, making it the perfect material for solar panels.

What are the 2 main disadvantages to solar energy?

However, solar energy does still have significant disadvantages which we should be aware of. The 2 main disadvantages of solar energy are dependence on weather conditions and the inability to store electricity. Solar energy output depends mostly on direct sunlight.
