Photovoltiac PV panels should be installed where there they will get significant shade-free sun every day. The most common example of rooftop shading includes trees, chimneys, roof peaks, neighboring structures and utility poles.
A little amount of shading, perhaps from a vent pipe or utility pole, will not have much impact on the overall system output. However, trees and other structures can have a big impact. A good rule of thumb is the object creating shading should be twice as far away as it is higher than the solar panels. For example, if the object creating shade is 10 feet higher than the panels, it needs to be at least 20 feet away from them. When our solar technician does a site visit, he will take many measurements that will calculate the expected energy output for your system during all times of day throughout the year.
Photovoltaic panels can use direct or indirect sunlight to generate power, but they are most effective in direct sunlight. Solar panels will still work even when the light is reflected or partially blocked by clouds. Rain actually helps to keep your panels operating efficiently by washing away any dust or dirt. Every house is different and the amount of electricity you use depends on your lifestyle, how efficient your home and your appliances are.

When your system is not producing electricity at night, you will receive electricity from the grid as normal. Any excess energy generated during the day for a given billing period is sent back to the utility company, which gives you a credit. This excess energy is reflected on your monthly bill as a credit which further reduces your bill. We make sure each installation is custom built depending on the unique power needs of each residence.
