Sensors and controllers should be checked periodically for calibration and alignment. Since solar cells are attached in strings, just one hot spot can lead to multiple cells functioning poorly. The good news is that the higher quality panel, the less natural degradation. 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. From the key issues to contracts structure, all explained in brief. Once the PV solar plant has been builtit needs to be efficiently operated and carefully maintained. Regular cleaning and maintenance will be enough in these cases.

The following table summarizes the degradation rates of solar panels made of different materials. This is called natural degradation, and is completely normal for all solar cells to experience once in operation. Become a member Sign in Get started. Other common unscheduled maintenance requirements include poweer are not limited to:. The degradation rate must be weighed against the cost and the utility of particular materials from which the solar models are made. It can also be covered ooeration warranties.

Here, again, crystalline silicon stands out, as do 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

Quite the contrary, high temperatures can actually damage solar panels, leading to the emergence of the hot spots. Different components of PV solar plant may fail during the operation. As in ppower case with panel cracking, not much can be done once the panel became discolored, hence the solar panels must be carefully operated and maintained.

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. This is important to take into account in budgeting and investment planning.

First, panels might crack, even in the new once, if they have been damaged in the manufacturing powee. In some cases it is not needed, if the grounding system is effective enough to reduce the lightning strike energy.

All solar cells naturally degrade over time, regardless of the environment they are in. Similarly, tracking systems also require maintenance checks. Hot spots occur when a panel is shaded, damaged, or electrically mismatched and decrease power output. Maintenance can be broken down in two parts:.

The cracks may lead to the failure of panels or losses of optimal efficiency. Note that copper conductor may be tinned, and that aluminium is not allowed to be anf into the soil. As is clear from the table, Solar DAO PV plants are among the most robust ones, since the solar panels used are made of crystalline silicon which is characterized by the one of lowest annual degradation rates.

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

Compared to other power generating technologies, solar PV power plants have low maintenance and servicing requirements. Panel orientation is an issue for static PV solar systems.

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.

Preventative Maintenance PM includes the following activities:. To solve this problem, all shading should be negated, and electrical connections should be optimized. As a result, solar cells are less exposed to solar irradiation, and generate less energy. Contrary to the common misleading opinion, solar panels are most efficient when they gain maximum solar irradiance, not maximum temperature. Depending on the material, the rate of degradation can vary.

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 the control and power cables, servicing of the gearboxes and ensuring that the levels of lubricating fluids are appropriate.

Finally, depending on the environmental conditions, the panels filehype be protected from wind, snow, and soiling in dusty areas.

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. Even with a proper grounding system, a PV installation can still be at maintenancf from lightning.
