29 Sep The Truth About Shading and Solar
The shading from surrounding buildings and trees is one of the biggest factors in determining whether solar panels are suitable and beneficial for your house. Obviously, the removal or trimming of the source of shading would be the most straightforward solution. But that’s not always possible. But don’t let that stop you from considering solar energy for your home or business—we have solutions!
Many things must be considered when tackling even the smallest amount of shading on a roof. During our preliminary site survey, a solar professional determines where and when a roof is shaded. That’s powerful information that we use to decide the best possible location of your solar array.
So what if you have unavoidable shading? Imagine a chain with one very weak link. As you can imagine, that chain is only as strong as its weakest link. Now imagine a small cloud in the sky that covers only a few panels in your array, or a tree branch that casts a shadow on one solar panel in the evening hours of the day. That same “chain” theory could be applied to your array of solar panels—the weakest “link” in that series will limit the effectiveness of the others.
For one customer, we tackled that very problem by using the technology of SolarEdge to our advantage. Power optimizers are installed with every solar panel, giving each one a “brain” that is in non-stop communication with the solar inverter (the unit that turns DC electricity into AC electricity). So now, whenever a cloud rolls in, or that tree begins casting a shadow, the power optimizer allows each module to produce the maximum energy, eliminating power losses by harvesting more power from the sun—and ultimately growing your savings.
