Commercial Solar FAQ

Q: What makes solar power attractive for business owners?

A:  Solar electric systems are eligible for the five (5) year Modified Accelerated Cost Recovery System (MACRS).  System life is typically much greater than 25 years.  This accelerated depreciation on a long life system dramatically increases the after-tax financial return of the project.  With SRECs trading at $0.25-$0.50 per kWh, larger systems are paying for themselves in less than 5 years.

Q:  Can I cover my roof with solar panels?

A:  Often 50-80% of roof space is usable. Remember that solar panels are extremely shade intolerant, so vent stacks, chimneys and other obstructions that may shade the panels must be avoided.

Q:  Can I put solar panels on a flat rubber membrane roof?

A:  Yes, on a membrane roof we install a ballasted system to reduce roof penetrations.  These arrays are designed to keep the solar panels at a low angle (about 10 degrees) to reduce wind loading but still perform better than lying flat on the roof.We ensure that the amount of ballast used is appropriate for the design and the existing structure.
