PV Panels Mounted on Roof

 

 

• PV array can be mounted on rooftops, generally with a few inches gap and parallel to the surface of the roof. If the rooftop is horizontal, the array is mounted with each panel aligned at an angle.

 

• If the panels are planned to be mounted before the construction of the roof, the roof can be designed accordingly by installing support brackets for the panels before the materials for the roof are installed.

 

• The installation of the solar panels can be undertaken by the crew responsible for installing the roof. If the roof is already constructed, it is most probably designed so that it is capable of bearing only the weight of the roof. For installing solar panels in such roofs, the roof structure must be strengthened before-hand with particular consideration to weather sealing or the roof can be converted to composition shingles wherever the panels are planned to be installed. By converting to composition shingles, the weight of the removed roof materials can compensate the additional weight of the panels structure. The general practice for installation of roof mounted solar panels include having a support bracket per hundred watts of panels.[3][4] To Learn More Click Here

 

 

 

  PV Panels Ground Mounted

 

Ground mounted PV systems are usually large, utility-scale photovoltaic power stations. The PV array consist of solar modules held in place by racks or frames that are attached to ground based mounting supports.[5][6]

 

Ground based mounting supports include:

• Pole mounts, which are driven directly into the ground or embedded in concrete.

• Foundation mounts, such as concrete slabs or poured footings

• Ballasted footing mounts, such as concrete or steel bases that use weight to secure the solar module system in position and do not require ground penetration. This type of mounting system is well suited for sites where excavation is not possible such as capped landfills and simplifies decommissioning or relocation of solar module systems. To Learn More Click Here
