Photovoltaic modules are the most significant hardware in photovoltaic power age. On the off chance that exceptional conditions happen during day by day establishment and activity and support, it will cause problem area impact of photovoltaic modules c channel sizes and potential prompted constriction impact (PID), causing misfortunes for most of proprietors. Care ought to be taken to control the PV plant to stay away from these two impacts when introducing and routinely keeping up the plant.
1. problem area impact
The sun oriented cell module that is protected in an arrangement branch will be utilized as a heap to expend the vitality produced by other lit up sun based cell parts. The concealed sun powered cell part will warmth up right now, which is the problem area impact. This impact can genuinely harm the sun based cell. Some portion of the vitality created by a sun oriented cell with light might be devoured by the clouded battery. The problem area impact might be only a bit of winged creature droppings. So as to keep the sun oriented cell from being harmed by the problem area impact, it is desirable over associate a detour diode between the positive and negative terminals of the sun oriented cell module to avoid the vitality created by the photovoltaic module from being devoured by the protected part. At the point when the problem area impact is extreme, the detour diode might be separated and the get together wore out.
2. PID impact
The potential-prompted lessening impact is that the battery get together has a long haul under high voltage, causing spillage flow between the glass and the bundling material, and a lot of electric charge is struck on the outside of the battery sheet, with the goal that the passivation impact on the outside of the battery is decayed, bringing about lower than the plan standard of the part. At the point when the PID marvel is not kidding, it will cause the PV module capacity to weaken by over half, subsequently influencing the power yield of the whole string. High temperature, high dampness, high saltiness and beach front zones are most inclined to PID marvel.
The working rule of sun powered Solar Panels control age framework:
1. Working guideline of framework associated framework:
The network associated photovoltaic power age framework has a sun based cell exhibit that changes over light vitality into electrical vitality, and enters the lattice associated inverter through the DC wiring box. A few kinds of network associated photovoltaic frameworks additionally should be arranged with battery packs to store DC control. The AC power yield by the inverter is utilized for the heap, and the overabundance electric vitality can be sustained back to the open power network (which can be called selling power) through a power transformer or something like that. At the point when the framework associated PV module framework is inadequate for power age because of atmosphere reasons or its own capacity utilization is excessively enormous, the open lattice can be enhanced with AC control (called power buy).
2. Working guideline of off-network framework:
The center part of sun oriented photovoltaic power age is the sunlight based board, which changes over the sun oriented light vitality legitimately into electrical vitality, and stores the electric vitality created by the sun oriented battery in the capacity battery through the controller. At the point when the heap is fueled, the electrical vitality in the battery is sensibly disseminated to the different loads through the controller. The current produced by the sunlight based cell is immediate current, which can be legitimately applied as immediate current, or it very well may be changed over into rotating current by a substituting current inverter for use by an exchanging current burden. The vitality produced by sunlight based power can be utilized promptly, or it tends to be put away by a vitality stockpiling gadget, for example, a battery, and utilized when required.
