These are mounted based on geographic location at fixed angle.
1.1 Roof Mounting
The solar array of a PV system 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 relatively easy to retrofit panels directly on top of existing roofing structures. For a small minority of roofs (often not built to code) that are designed so that it is capable of bearing only the weight of the roof, installing solar panels demands that the roof structure must be strengthened before-hand. In all cases of retrofits particular consideration to weather sealing is necessary.
1.2 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.
Ground based mounting supports include:
Mounting with Solar Trackers
These are fully automated solar tracking systems, they normal achieve 35% to 40% extra yield.
Module monitoring portal allows for enhanced maintenance and yield assurance through module-level performance monitoring, fault detection and automatic alerts localized on a virtual site map for accurate troubleshooting. The monitoring web-based portal can be accessed from any browser or from any Android or iOS (Apple) smart-phone or tablet using the Opera Mobile or Firefox web browsers.
