How to improve the power generation efficiency of existing photovoltaic power stations?

With the growing global demand for clean energy, photovoltaic power stations, as an important part of renewable energy, are particularly important for improving their system efficiency. For existing photovoltaic power stations, a series of scientific and effective measures can significantly improve power generation efficiency without increasing a large amount of investment, thereby achieving higher economic and environmental benefits.

Optimization of photovoltaic module performance

1)Selection of high-efficiency photovoltaic modules: Photovoltaic modules are the core components of photovoltaic power stations, and their photoelectric conversion efficiency directly determines the power generation of the power station. In existing photovoltaic power stations, if conditions permit, it is possible to consider gradually replacing low-efficiency photovoltaic modules with high-efficiency modules. Greenwatt 730W N type mono Topcon bifacial solar panel with power efficiency 24%,will be your good choice on solar power plant.

2)Module cleaning and maintenance: Dust, dirt, bird droppings and other pollutants will adhere to the surface of photovoltaic modules, reduce their light transmittance, and thus affect power generation efficiency. Therefore, regular cleaning of photovoltaic modules is an important measure to improve system efficiency.

Inverter performance improvement

1)Select high-efficiency inverter: The inverter is a key device that converts the direct current generated by the photovoltaic module into alternating current. Its performance directly affects the power generation efficiency and power quality of the pv power plant. In the built photovoltaic power station, if the inverter efficiency is low or there is a fault, it should be replaced with a high-efficiency inverter in time. Greenwatt 125KW grid tied solar power inverter with 8 mppt trackers,max efficiency up to 98.8%

2)Inverter capacity matching: The capacity of the inverter should match the power of the photovoltaic array. If the inverter capacity is too large, it will cause a waste of resources; if the capacity is too small, it will limit the power generation capacity of the photovoltaic array. In the built photovoltaic power station, the capacity of the inverter should be reasonably selected according to the actual power of the photovoltaic array and the future expansion plan.

Energy storage system application

The energy storage system can provide power support when there is insufficient sunlight or when the grid demand is at peak, and enhance the power supply stability and power generation efficiency of the power station.

In the built photovoltaic power station, if conditions permit, it is possible to consider adding an energy storage system.

1) Capacity configuration: According to the power generation, power demand and grid access conditions of the power station, the capacity of the energy storage system is reasonably configured. Ensure that the energy storage system can provide sufficient power support when there is insufficient sunlight, and release electricity when the grid demand is at peak to obtain higher economic benefits.

2) Optimization of charging and discharging strategies: Formulate reasonable charging and discharging strategies to ensure the efficient operation of the energy storage system. For example, when there is sufficient sunlight, the energy storage system is charged first; when there is insufficient sunlight or when the grid demand is at peak, the energy storage system is released first.
