What Could Go Wrong With Your Rooftop Solar Panel Installation?

A solar rooftop can not only help to reduce your household's carbon footprint, but it can help you save on energy costs. Unfortunately, some mistakes are made during the selection and installation of the rooftop, which results in fewer savings. In some instances, a new rooftop is even necessary. If you are planning to install a solar system on your rooftop, here are three mistakes to avoid:

Installing the Roofing Without a Thorough Evaluation

The solar panels that are installed on your rooftop can last for a decade or more. If your roof is not structurally sound or does not have much life left in it, you could be forced to make extensive repairs to your roofing soon.

Regardless of the size of your solar array, you need to have your roofing inspected by a contractor. He or she will determine if your home and roof can handle the additional weight of the solar panels. He or she will also estimate how much of a lifespan your roof has. If it is time for a new roof, now is the time to have it installed.

Choosing a Solar Array That Is the Wrong Size

Solar contractors use various ways to determine the size of your system that is needed for a home. Unfortunately, one of the methods used does not provide the most accurate option for determining the solar array needed for a home.

If the recommended system is based on the average amount of your electric bill, the system might be too small or too large. Instead of relying on the dollar amount, the actual amount of usage per hour should be considered. The information, combined with data about your climate, will provide the most accurate assessment of your household's energy needs.

Installing the Panels in the Wrong Direction

The solar panel system on your rooftop is only effective if it is installed in the right direction. The panels need to face towards the sunlight to absorb energy. If the panels are facing the wrong direction, there might be some energy absorbed, but not enough to get the full benefit of the system.

Installing the panels on the south-end of your home is likely the best position, but there are factors that could result in other areas being better. For instance, if there are trees blocking the sunlight, another position is likely better.

To avoid any problems, work closely with your installer to select and install the solar panels on your home's rooftop. Contact a company like DFW Solar Electric for more information and assistance.
