Generally, inverter faults are the most common cause of system downtime in PV power plants. This is called filetypr degradation, and is completely normal for all solar cells to experience once in operation.

To solve this problem, all shading should be negated, and electrical connections should be optimized. This will include an inspection of support structure foundations for evidence of erosion from water run-off. As is clear from the table, Solar DAO PV plants are among mainteannce 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 good news is that the higher quality panel, the less natural degradation. Maintenance can be broken down in two parts:. Here, again, crystalline silicon stands out, as do conventional solar panels as opposed to concentrating photovoltaics that uses lenses aand 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

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 ooeration. Feel free to leave a comment below. Contrary to the common misleading opinion, solar panels are most efficient when they gain maximum solar irradiance, not maximum temperature.

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

Usually, manufacturing companies that produce solar modules offer warranties if degradation rate exceeds certain amounts, for example, if it is more than 0.

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.

The first level of such protection is the filetyype mount system itself, whereby the grounding system redirects the energy from the lightning into the ground and away from the panels. Depending on the material, the rate of degradation can vary. In some cases it is not needed, if the grounding system is effective enough to reduce the lightning strike energy. First, panels might crack, even in the new once, if they have been damaged in the manufacturing process.

poweer Depending on the foundation, different forms of grounding can be used, as summarized in the following table provided by the Desert Research Institute:. PV solar plant is a structure of considerable size, which is why some lightning protection is in order. Similarly, tracking systems also require maintenance checks. Become a member Sign in Get started. All solar cells naturally degrade over time, regardless of the environment they are in. Their serviceable life is up to 25 years, with 10 years of guaranteed performance.

Other common unscheduled maintenance requirements include but are not limited to:.

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. The reason it leads to loss of efficiency is because different color panels changes the wavelength of light that can be absorbed. The following table summarizes the degradation rates of solar panels fietype of different materials. The alignment and positioning of the tracking system operatlon also be checked to ensure that it is functioning optimally.

Compared to other power generating technologies, solar PV power plants have low maintenance and servicing requirements. Preventative Maintenance PM includes the following activities:. 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. This is important to abd into account in budgeting and investment planning. As a result, solar cells are less exposed to solar irradiation, and generate less energy.

Since solar cells are attached in strings, just one hot spot can lead to multiple cells functioning poorly. 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.

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