Some of these factors are controllable, such as dust obstruction, weed obstruction, and equipment malfunctions causing downtime. Regular cleaning and weeding can mitigate losses caused by dust and weed obstruction, while rapid troubleshooting can reduce losses from equipment downtime, thereby increasing the power plant's output.
Meteorological factors, component degradation, and design flaws (blocking of front and rear rows of components, blocking of left and right rows of components, and blocking of nearby buildings) are uncontrollable factors that cannot be changed in the later operation and maintenance of the power plant (unless a large-scale power plant technical upgrade is carried out), and will continue to affect the power generation of the power plant.
So, how can we ensure a photovoltaic power station operates efficiently and generates a high amount of electricity over 25 years? The following aspects should be controlled:
1. The location must be good.
This is a necessary condition. If a photovoltaic power station is located in an area with poor solar energy resources or next to a mine, the power generation of the completed photovoltaic power station will certainly not reach the expected value.
2. Strictly control the design, procurement, and construction processes.
Every stage of photovoltaic power plant design, procurement, and construction must be strictly controlled. Otherwise, any weakness in any stage will cause great difficulties for later operation and maintenance, and may even lead to the inability to operate and maintain the power plant, seriously affecting the performance of the entire power generation system.
3. Standardized power plant operation and maintenance management
Operation and maintenance management is the core of a photovoltaic power plant. Operation and maintenance account for 98% of the entire lifecycle of a photovoltaic power plant, and good operation and maintenance management is the fundamental guarantee of power generation.
If power plant operation and maintenance management is inadequate, such as failing to respond promptly (or even not responding at all) to equipment failures and shutdowns, it will inevitably affect the power plant's power generation. Furthermore, the power loss due to the failure will increase as the failure duration lengthens. Conversely, if power plant operation and maintenance management is standardized and meticulous, with maintenance personnel responding immediately to equipment failures and quickly troubleshooting and eliminating problems on-site, then equipment failure losses can be effectively reduced, thereby increasing the power plant's power generation.
