Even after the lightning energy has been discharged into the ground, it can still cause a power surge within the solar panels array, which is why a surge protection equipment is in order. Since solar cells are attached in strings, just one operaiton spot can lead to multiple cells functioning poorly.

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

plsnt It is also important to use the same type of metal in both the grounding system and in the protection equipment, so as to avoid corrosion. The degradation rate filetypw be weighed against the cost and the utility of particular materials from which the solar models are made. This is important to take into account in budgeting and investment planning. The alignment and positioning of the tracking system should also be checked to ensure that it is functioning optimally.

The following table summarizes the degradation rates of solar panels made of different materials. Even with poower proper grounding system, a PV installation can still be at risk from lightning. This is called natural degradation, and is completely normal for all solar cells to experience once in operation. Blocked Unblock Follow Get updates.


From the key issues to contracts structure, all explained in brief. As a result, solar operarion are less exposed to solar irradiation, and generate less energy.

Feel free to leave a comment below. First, panels might crack, even in the new once, if they have been damaged in the manufacturing process.

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

Compared to other power generating technologies, solar PV power plants have low maintenance and servicing requirements. All solar cells naturally degrade over time, regardless of the environment they are in. Different components of PV solar plant may fail during the operation. Contrary to the common misleading opinion, solar panels are most efficient when they gain maximum solar irradiance, not maximum temperature.

PV solar plant is a structure of considerable size, which is why some lightning protection is in order. Generally, inverter faults are the most common cause of system downtime in PV power plants. Natural degradation cannot be prevented, but must be taken into account in the planning process. The cracks may lead poewr the failure of panels or losses of optimal efficiency. Once the PV solar plant has been builtit needs to be efficiently operated and carefully maintained. The module mounting assembly, cable conduits and any other structures built for the solar PV power plant should be checked periodically for mechanical integrity planr signs of opeeation.

Depending on the material, the rate of degradation can vary. As in the case with panel cracking, not much can be done once the panel became discolored, hence the solar panels must be carefully ppower and maintained.

It can also be covered by warranties. Usually, manufacturing companies that produce solar modules offer warranties if degradation rate exceeds certain amounts, for example, if it is more than 0. Depending on the foundation, different forms of grounding can be used, as summarized in the following table provided by the Desert Research Institute:.


Sensors and controllers should be checked periodically for calibration and alignment. The reason it leads to loss of efficiency is because different color panels changes the opperation of light that can be absorbed. To solve this problem, all shading should be negated, and electrical connections should be optimized.

Preventative Maintenance PM includes the following activities:. Panel orientation is an issue for static PV solar systems.

Note that copper conductor may be tinned, and that aluminium is not allowed to be buried into the soil. Regular cleaning and maintenance will be enough in these cases. Other common unscheduled maintenance requirements include but are not limited to:.

Become a member Sign in Get started. This will include an inspection of support structure foundations for evidence of erosion from water run-off. The first level of such protection is the ground mount system itself, whereby the grounding system redirects the energy from the lightning into the ground and away from the panels.

Finally, depending on the environmental conditions, the panels must be protected from wind, snow, and soiling in dusty areas. Quite the contrary, high temperatures can actually damage solar panels, leading to the emergence of the hot spots. Their serviceable life is up to 25 years, with 10 years of guaranteed performance. In general, the checks will include inspection for wear and tear on the moving parts, servicing of the motors or actuators, checks on the integrity of filteype control and power cables, servicing of the gearboxes and ensuring that the levels of lubricating fluids are appropriate.

Maintenance can be broken down in two parts:.
