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

Once the PV solar plant has been builtit needs to be efficiently operated and carefully maintained. PV solar plant is a structure of considerable size, which is why some lightning protection is in order.

From the key issues to contracts structure, all explained in brief. Regular cleaning operatino maintenance will be enough in these cases.

Usually, manufacturing companies that produce solar modules offer warranties if degradation rate exceeds certain amounts, for example, if it is more than 0. The reason it leads to loss of efficiency is because different color panels changes the wavelength of light that can be absorbed. Maintenance can be broken down in two parts:.

The first level of such protection is the ground mount system itself, whereby the grounding system redirects the energy p the lightning into the ground and away from the panels. To solve this problem, all shading should be negated, and electrical connections should be optimized.

The good news is that the higher quality panel, the less natural degradation. Note that copper conductor may be tinned, and that aluminium is not allowed to be buried into the soil. Compared to other power generating technologies, solar PV power plants have low maintenance and planf requirements. This oslar called natural degradation, and is completely normal for all solar cells to experience once in operation.

Visual discoloration is another common defect that reduces the amount of sunlight that penetrates into a solar cell. As a result, solar cells are less exposed to solar irradiation, and generate less energy. This will ppwer an inspection of support structure foundations for evidence of erosion from water run-off. Natural degradation cannot be prevented, but must be taken into account in the planning process.

Since solar cells are attached in strings, just one hot spot can lead to multiple cells functioning poorly. Different components of PV solar plant may fail during the operation.

This is important to take into account in budgeting and investment planning. The cracks may lead to the failure of panels or losses of optimal efficiency. Their serviceable life is filrtype to 25 years, with 10 years of guaranteed performance.

Feel free to leave a comment below. Hot spots occur when a panel is shaded, damaged, or electrically mismatched and decrease power output. Even with a proper grounding system, a PV installation can still be at risk from lightning. First, panels might crack, even in the new once, if they maiintenance been damaged in the manufacturing process.

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. 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 poqer is characterized by the one of lowest annual degradation rates.

The degradation rate must be weighed against the cost and the utility of particular materials from which the solar models are made. Quite the contrary, high temperatures can actually damage solar panels, leading to the emergence of the hot spots.

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. The module mounting assembly, cable conduits and any operattion structures built for the solar PV power plant should be checked periodically for mechanical integrity and signs of corrosion.

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. Sensors and controllers should be checked periodically for calibration and alignment.
