If your roof is in the sun all day, it might be a good candidate for solar panel installation so you can run your home on solar power. While putting in solar panels will be an initial expense, it is nice to rely on the sun to power your home so you can reduce your monthly utility bills. Here are some of the steps involved with installing solar panels on your roof.
Have a Solar Evaluation
If your home is in the shade most of the day due to nearby trees, don't assume you can't have solar panels put on. Instead, get an evaluation from a solar power expert who can assess your property to see how much sun your roof actually gets. An evaluation determines the right place on your roof to place the panels for optimal sunlight, which is usually the south or west side. The configuration of your house plays a role in where the panels are placed too.
If it turns out your roof doesn't get enough sunlight, you might consider options like removing trees that are close to your house. An evaluation can also estimate how removing a tree will affect the amount of sun on your roof so you don't go through the expense of tree removal only to find out your roof still has too much shade.
Replace or Repair Your Roof
The roofer will inspect your roof to make sure it can handle the extra weight of the solar panels. They can also look for problems on the roof that should be repaired before the panels are put on. Your roof should be in excellent shape before the panels go on because repairs may be difficult to do once the panels are in place. If your roof has a lot of damage or if your roof is old, then the roofer might recommend you have a new roof put on so you start with a fresh and sturdy surface for your new solar panels. However, if your roof is already in good shape, then you don't need to replace it when you get solar panels.
Decide on the Method of Installation
Solar panels have to be attached to the roof so they stay put in strong winds. Your roofer will let you know the options for installing the panels. You may not have a choice with certain types of roofing, such as asphalt shingles, since these require that the panels be bolted to the roof. If you have standing seam metal roofing, it might be possible to clamp the panels to the ridge of metal and avoid making punctures. However, it's usually possible to attach the panels to the roof with screws too. Your roofer may have a preferred installation method, or you might have some input in the way you want the panels installed.
