Let Allied Engineering be a part of your
next solar canopy feasibility study and project.

Solar canopy PV arrays have become more common, even in our northeast regions. These solar canopies cover large open and underutilized hardscape spaces; vehicle parking areas. While at the same time they do not impact existing green space nor affect roof area loading. A typical parking garage canopy can harvest approximately (18 to 20) kWh/year per square foot. Solar canopies, because of the additional structural infrastructure, will have a higher first cost than other fixed-mount systems and therefore a longer return on investment period as directly related to the installation. However, there are many other great benefits to consider.
A solar canopy PV array installation can provide :
- Reduced electrical utility bills when using the year-round, on-site, harvested solar electrical energy
- Increased facility or property value from the installation of this amenity
- Reduced maintenance of the respective parking garage structure or the parking lot spaces
- Increased protection from weather elements for the vehicles parked beneath the solar canopy
- Expressed corporate commitment to sustainability through environmentally friendly energy production
- Reduced “urban heat island effect” by decreasing exposed hardscape to the sun
- Received rebates from available utility company SREC programs
- Decreased light pollution from parking area lighting system located beneath the solar canopy
- Lowered lighting power density (watts per square foot) for parking area lighting system located beneath solar canopy

A project in northern Massachusetts installed a (42,000) SF solar canopy that covered the upper deck of an existing parking garage adjacent to its respective office building. The PV system output was connected to the office building electrical service to help offset the facility electrical bill. The system utilized approximately (2300) 320 Watt solar panels for a total system capacity of (736) kW. Many newer systems are utilizing solar panels with a 400 Watt or more output. The projected annual harvest for this project was in the range of (800,000 to 835,000) kWh/year.
Allied Engineering can organize a complete design-build team utilizing our full staff of engineers in collaboration with solar energy general contractors, solar energy system integrators, steel erectors and electrical contractors in New England. We can also provide the traditional design-bid-build package and engineering services should that be desired.

What is your dream vacation and why?
A cruise of Norwegian Fjords or of the Mediterranean Sea. The first one would be to experience the calm relaxing natural views and the second one to experience so many different cultures.
