If you want to install solar power at a home, the roof is the ideal place your technicians recommend to install the solar module array. But the question remains that can that roof withstand the wait of the array? A single solar module is not that heavy but for an array of them the weight is significant. Question arise all through the process before purchasing and installing. What are the impacts of installing that solar array on my roof?
This impacts can be negative and others are very positive. With this impacts, you as the business owner has to weigh and compare between the positives and negative before installing the solar array on his/her roof top. Or else if something goes wrong and you get sued, you might end up losing your business licenses which means the business get banned.
When considering the condition of the roof, one would have to think and do proper survey for the roof before installing the solar modules on the roof. This is because solar panels have a warranty of 25-30 years. This means the array would stay on your roof top for that amount of time same to the solar panel warrant.
So what happens if you install your solar panels and after 15 years your roof calls for repair?
You would need to unmount your solar module and mount the back when your new roof is done. And when your solar panels are disconnected or rather unmounted there is no power generation. For the two week of replacing your roof you would need to use electricity from the utility company thus increasing your electricity bill. It would be more economic to replace your roof before installing solar arrays on your roof top if the need be.
Considering the efficiency of the solar module on your roof top, the effectiveness would be affected too. Look at it that when installing the solar array in is advised that they should be tilted at a particular angle and facing the suns path which is the equator. In solar home systems solar panels assume the roof pitch angle which may not be the optimal angle. Some roofs are even so highly elevated that one side of the roof is usually shaded in the afternoon.
Once the solar panels are installed on the roof top, the owner is very excited that he/she maintains them dearly. Going up once in a while wiping of the dust, leaves and moss that may have accumulated on top. But as the house change hands the care seems to fade and with years passing no one would care about the array anymore I guess. So generally the efficiency is affected the same as any other components and the system would fail with time.
It is true to say that the solar shingles do protect your roof top and cool the attic. But I wouldn’t say it makes it hard to replace and repair your roof. It makes it expensive.
Solar electric panels come with a very long warrant. They are expected to perform even more than their warrants since they are no mechanical systems on them. Considering this long life of the solar panels it would be reasonable to repair and replace your roof before installing your solar panels on your roof top. It is very easy to repair the roof before instead of installing the solar panels then there after you unmount them to replace your roof and then reinstall them.
All these should be observed to ensure the effectiveness of the system. I recommend that business owners train their technicians to assess an installation site before installing. Also it would be advisable that the company comes up with training manual on the system operations and maintenance.
These points should be highly observed. You don’t want to be that company which has very poor review from your customers. Best way to remedy these impacts is to train your technicians on all components that you company uses in the installation.
Remember that your technicians are the once involved dearly in the customer welfare; they are the one relating with your clients on ground level so you have to train them and show them the business face that is required to achieve success.
