There aren’t many physical reasons to make solar unsuitable, as each solar panel ystem is highly adaptable, and should be designed with each customer in mind.  There are a few instances though when the solar power system is not suitable for your home. These include:  A southwest or south roof orientation. This is not the most desirable angle for attracting the most sunlight, as it is not very efficient. No space on roof due to chimneys, skylights, solar hot water etc. Your roof is made of asbestos.  Your roofing is very old & flimsy/ rusted that would break easily or have slate roof tiles. Most of these reasons we can work around, such as providing a stand-alone solar system in a more efficient spot for sunlight than on your roof. For safety reasons, we can not install on asbestos roofing.  If you are unsure or have any enquiries, please contact us.
