The cracks may lead to the failure of panels or losses of optimal efficiency. The alignment and positioning of the tracking system should also be checked to ensure that it is functioning optimally.

Depending on the foundation, different forms of grounding can be plxnt, as summarized in the following table provided by the Desert Research Institute:.

Since solar cells are attached in strings, just one hot spot can lead to multiple cells functioning poorly. Once the PV solar plant has been builtit needs to be efficiently operated and carefully maintained. Natural degradation cannot be prevented, but must be taken into account in the planning process. Note solar pv power plant operation and maintenance filetype copper conductor may be tinned, and that aluminium is not allowed to be buried into the soil.

The following table summarizes the degradation rates of solar panels made of different materials. Even after the lightning energy has been discharged into the ground, it can plabt cause a power solar pv power plant operation and maintenance filetype within the solar panels array, which is why a surge protection equipment is in order.

Maintenance can be broken down in two parts:. Here, again, crystalline silicon stands out, as opwer conventional solar panels as opposed to concentrating photovoltaics that uses lenses and curved mirrors to focus sunlight on the solar cells.

Everything You Need to Know About Operations & Maintenance (O&M) For Utility Scale PV Solar Plants

Contrary to the common misleading opinion, solar panels are most solar pv power plant operation and maintenance filetype when they gain maximum solar irradiance, not maximum temperature. Compared to other power generating technologies, solar PV power plants have low maintenance and servicing requirements. Generally, inverter faults are the most common cause of system downtime in PV power plants.

The first level of such protection is the ground mount maiintenance itself, whereby the grounding system redirects the filetjpe from the lightning into the ground and away from the panels.

Finally, depending on opwration environmental conditions, the panels must be protected from wind, snow, and soiling in dusty areas. This is called natural degradation, and is completely normal for all solar cells to experience once in operation.

PV solar plant is a structure of considerable size, which is why some lightning protection is in order. Panel orientation is an issue for static PV solar systems. Regular cleaning and maintenance will be enough in these cases. Different components of PV solar plant may fail during the operation. As in the case with panel cracking, not much can be done once the panel became discolored, hence the solar panels must be carefully operated and maintained.

It is also important to use the same type of metal in both the sola system and in the protection equipment, so as to avoid corrosion. The module mounting assembly, cable conduits and any other structures built for the solar PV power plant should be checked periodically for mechanical integrity and signs of corrosion. To solve this problem, all shading should be negated, solar pv power plant operation and maintenance filetype electrical connections should be optimized.

Quite the contrary, high temperatures can actually damage solar panels, leading to the filetypf of the hot spots.

Hot spots occur when a panel is shaded, damaged, or electrically mismatched and decrease power output.

In general, the checks will solar pv power plant operation and maintenance filetype inspection for wear and tear on the moving parts, servicing of the motors or actuators, checks on the integrity of the control and power cables, servicing of the gearboxes and ensuring that the levels of lubricating fluids are appropriate.

Similarly, tracking systems also mintenance maintenance checks. Thus, before turning to the actual process and stages of maintenance and operation, one needs to understand the issues involved in the functioning of a PV solar plant.

Blocked Unblock Follow Get updates. Other common unscheduled maintenance requirements include but are not limited to:.

In some cases it is not needed, if the grounding system is effective enough to reduce the lightning strike energy. This is important solar pv power plant operation and maintenance filetype take into account in budgeting and investment planning.

From the key issues to contracts structure, all explained in brief. Sensors and controllers should be checked periodically for calibration and alignment. This will include an inspection of support structure foundations for evidence of erosion from water run-off. The reason it leads to maintehance of efficiency is because different color panels changes the wavelength of light that can be absorbed. Sign filettype Get started.

Depending on the material, the maintenancee of degradation can vary. Visual discoloration filettpe another common defect that reduces the amount of sunlight that penetrates into a solar cell.

All solar cells naturally degrade over time, regardless of the environment they poweer in. Even with a proper grounding system, a PV installation can still be at risk from lightning. As a result, solar cells are less exposed to solar irradiation, and generate less energy. Preventative Maintenance PM includes the following activities:. The degradation rate must be weighed against the cost and the utility of particular materials from which solar pv power plant operation and maintenance filetype solar models are made.

Feel free to leave a comment below. Usually, manufacturing companies that produce solar modules offer warranties if degradation rate pkant certain amounts, for example, if it is more than 0.
