Want to know if your roof is a good fit for solar?
A few simple guidelines will help you to identify your solar viability:
For solar installations in the northern hemisphere, the consistent rule-of-thumb is: The more south facing the surface, the more energy the system will produce. Ideally, one would want to install the solar system on a surface within 40 degrees of directly South (180 degrees) to ensure optimal production from the solar system. Systems on flat roofs or mounted on the ground will be tilted to provide a south-facing exposure.
Consider the amount of shading from nearby obstructions which may impact your system. If you live in the suburbs, think shading from trees. If you live in the city, look for adjacent taller buildings that may shade the system. Think about anything that might impact the access of the sun on your roof. Would you consider removing an obstruction if it meant the difference between having solar or not?
Obstructions & Surface Area:
How much usable roof space do you have? Is your roof angular or does it have a lot of dormers? The more clear space the better, but we can work around your vent pipes, chimneys, and skylights .
Many people who are opting for solar power often choose to have a roof solar panel system installed. A suitable roof should receive sunlight without obstruction from another’s object (trees, buildings, foliage or other impediment).
Here is a free, easy way to check if you have a good site for solar:

There are some roof types that less compatible with solar. It is difficult for us to work on slate and wood roofs, because these roof materials are brittle and can break. They require specialized mounting components and equipment and we don't want to damaging your roof. This means that installations on slate and wood roofs are more expensive.

The roof solar panel system seems to be the most popular type found in urban or suburban neighborhoods. In all likelihood, though, there are probably just as many systems that are located somewhere else but are not as visible as the top of a house.
Our NABCEP certified solar professionals will be able offer good advice as to the best area of the home for the installation. It is true that a roof solar panel system may be the first choice, but other options will almost always exist. It is then left up to the preference of the home owner as to which type of system to choose.
Suitable Solar Roof
Because the top of the home with a roof solar panel system is the most visible configuration, nearly everyone just automatically assumes that this is the correct location for solar panels. However, this may not be the right area of installation for every home. Shade trees, other homes located in close proximity and other buildings can obstruct the top of a home. In these cases, it may be wise to consider other options.
It is good to have choices especially when these choices will have no direct impact on functionality. As long as the sun is shining on the solar panels, then this is an area that can be used.
