New federal regulations will place the ultimate liability of the effectiveness of solar panel installation on the homeowner. There are several things you need to consider before adding solar panels to your home.
When installing solar panels on your home, you have to make sure your roof is able to support the panels. First, because the frame is screwed directly to the rafters and the interlocked shingles are screwed to the frame, the roof must be able to withstand winds of up to 120 mph without damage. You will need to consider what size of setup you need based on the size of your home and, of course, your power needs.
You should consult a structural engineer to tell you if your roof is capable of handling the added load. Size of roof, how many stories your house has, roof style, and degree of pitch all play a big role in the solar panels you home can support. The solar industry has invented many different methods to attach panel-mounting hardware. Ideally you want radials run uniformly in all directions.

Most solar companies can install a rooftop residential solar panel installation in one to three days, depending on how many panels you’re installing and how complicated the installation is. Think about it this way: any panels that go on your roof are limited by the roof’s design, which isn’t exactly what works best for solar.
Direct sunlight for the entire day is optimal. You need a shade-free roof area because shadows affect the panels performance. Now, if a shadow is cast on even just one part of the solar panel in your array, the output from the entire system could be potentially compromised. This is called shading of PV panels. What can cause shading? Shading is usually caused due to environmental obstructions such are trees or nearby buildings. These shading effects are usually static due to the position of the obstruction.
If shade from a tree is cast on even one panel of the string, the output of the entire string can almost be zero for as long as the duration of the shade. Solar arrays are usually divided into “strings” of solar panels. One string can contain more than one solar panel.
How is this problem combated? Careful positioning of PV systems This is the most obvious solution to handle the problem of shading. It is extremely important to consider all times of the day for all seasons of the year when working out whether a nearby object can cast a shadow on your system. Probability of nearby trees which may grow tall enough or buildings that may come up in future also needs to be considered before installing your solar panels.
The main consideration should always be trust in the company you choose to install your solar panels. Check reviews, ask for references, and make sure you comfortable with your installation team before they start work on your home. Make sure your solar panel installation company has all of the proper licenses and permits to make sure you avoid any liability from these new federal regulations.
