TPO and Solar Application

Peter Knight owns several properties in the city of Philadelphia, including his home.  In late 2016, Peter wanted to take advantage of potentially expiring federal solar tax benefits and to produce enough solar power to cover his own usage.  Mr. Knight’s home was not optimal for placing solar arrays of a size that would accomplish his needs.

So he took advantage of a rule that allows the location from which the energy is produced to be credited to another location (Mr. Knight’s home) as long as it was within a 1.5 mile radius.  Since Mr. Knight owned a larger building along I-95 in the city, he was able to place enough panels on the roof to accomplish this goal, but also enough to realize a financial benefit as a result of available SREC credits.

The building Mr. Knight chose has a roof surface area of about 7,000 square feet.   This allowed for the easy fit of a 50 kW array.  Now the system is generating power as well as income for Mr. Knight.

GP Martini went to GAF for a custom design that would allow a 20 year NDL warranty using .050 Everguard Extreme TPO system, with solar arrays placed right on the surface.  GAF specified a multiple inspections during and after installation to ensure that the roof system would perform properly even with the large amount of foot traffic associated with installation of the solar panel system.  The roof has performed nicely and the solar arrays are generating plenty of power to keep Mr. Knight in comfort and profit.
