SPN’s installation method in no way interferes with your building’s roof membrane, the layer that keeps the weather on the outside separated from your business operations on the inside.
Our unique install method reduces the wind profile of the panels by tightly packing the panels at a low angle. The result is that the system can be secured against the weather with a ballasting system without
requiring any penetration of the rooftop.
The completed install adds just five pounds of static load per square foot to your roof (compared to twenty-five pounds or more for a traditional high-angle install) while also providing near-total shielding from UV radiation, the largest contributing factor to roof membrane degradation.
When the time comes to begin working on-site, we first install ground fencing to cordon off the work area, build a scaffold tower to allow access to your roof without increasing traffic on your existing roof access system, and install a safety perimeter along the edges of your roof.
On your roof, we lay down Styrofoam-backed plywood sheets to form walkways across your rooftop and a landing pad for the panels.
These sheets absorb and distribute weight to ensure that the install process is gentle on your roof.
The panel mounts are placed on cleared sections of roof. A protective membrane, that separates the panel mounts from the roof membrane, is used in all rooftop installations. The mounts are then connected in a grid in both directions so that every panel on the roof is secured to every other. An
appropriate buffer around vents, HVAC units and any other rooftop equipment is always kept clear.
The panels are then loaded onto the rooftop landing pad by a lift, then transported along the walkways and mounted individually by hand.
No more than six to ten people are on your roof at this time, the heaviest traffic of the entire install.
The panels are then wired together. The cables cross the roof bundled in elevated aluminum cable runners then travel down the side of the building to the inverter.
This process, as with the rest of the install, involves absolutely zero
The inverter is installed at ground level, at a location that’s convenient to the building owner.
Concurrent with the panel installation, a concrete pad is laid down for the inverter which is then delivered pre-assembled. Once seated, it is connected to the panels.
A cable is then run from the inverter back to the building, where the system is connected to the grid with its own meter.
The building’s electrical system remains completely untouched. Your energy bill will not change at all.
The system is now connected but inactive. Before the switch is flipped, however, a complete inspection of the site is performed by the local utility operator, the Ontario Power Authority, the Electrical Safety Authority, the Municipal Building Department, and an independent engineer.
The entire job, from the moment the crew arrives until the day the last worker leaves the property, can take as few as four weeks, and no more than seven, depending on the size and type of roof. At no time is there any need to interrupt the normal daily operation of the business.
