Can a truss roof support solar panels?

Installing solar panels will increase the weight on the structure of your roof. If the weight of these solar panels is too much for your roof to handle, there is a potential that it will collapse. This is very dangerous for many reasons, not to mention costly.
Why is it important to note the roof construction and spacing of rafters or trusses?
The spacing between rafters in a given building is part of the engineering calculations that determine the required structure of the roof. All of these factors taken together determine the maximum span of the rafters, a measurement that dictates how wide the building under the roof can be.
How much weight do solar panels add to a roof?
What is the maximum distance between roof trusses?
Roof trusses should be 24” apart, on center. Trusses are allowed to be closer together, at either 12” or 16” on center, but building codes allow for 24” on center spacing without using heavier duty fasteners for truss to wall connections.

What is the best angle for solar panels on a roof?
Most people consider the ideal angle for a solar panel to be 30 degrees. This translates to a roof pitch of about 7/12, meaning for every 12 inches of space horizontally, the height of the roof increases by seven inches.
