Composition and Working Principle of Photovoltaic (PV) Power Generation SystemsA photovoltaic (PV) power generation system is primarily composed of PV modules, a controller, an inverter, batteries, and other accessories (batteries are not required for grid-connected systems). Based on whether it relies on the public power grid, PV systems are divided into off-grid and grid-connected types. Off-grid systems operate independently without relying on the utility grid. They are equipped with energy-s

1. R&D of New Materials and Equipment & Asset Management1.1 R&D of New Materials and New ComponentsVarious new materials serve as the direct carriers for energy conversion, power transmission, and operation control in new-type power distribution and consumption systems, directly determining operational efficiency, safety, reliability, and system costs. For instance: New conductive materials can reduce energy consumption, addressing issues such as energy shortage and environmental pol

1. On a scorching sunny day, do damaged vulnerable components need to be replaced immediately?Immediate replacement is not recommended. If replacement is necessary, it is advisable to do so in the early morning or late afternoon. You should contact the power station’s operation and maintenance (O&M) personnel promptly, and have professional staff go to the site for replacement.2. To prevent photovoltaic (PV) modules from being hit by heavy objects, can wire mesh protective screens be install

1. What are the common faults of distributed photovoltaic (PV) power generation systems? What typical problems may occur in various components of the system?Common faults include inverters failing to operate or start due to voltage not reaching the startup set value, and low power generation caused by issues with PV modules or inverters. Typical problems that may occur in system components are burnout of junction boxes and local burnout of PV modules.2. How to handle common faults of distributed
