Issues Related to Solar Photovoltaic Systems

Ⅰ. About the solar photovoltaic system

The solar photovoltaic system consists of a solar cell group, a solar controller, and a battery (group). If the output power is AC 220V or 110V, an inverter is also required. Solar photovoltaic systems are divided into off-grid photovoltaic power generation systems, grid-connected photovoltaic power generation systems and distributed photovoltaic power generation systems.

Ⅱ. Problems related to solar photovoltaic system

1. Will there be insufficient power when it is cold in winter?

The power generation of a solar PV system is indeed affected by temperature. The factors that directly affect the power generation are the radiation intensity and sunshine duration, as well as the operating temperature of the solar cell modules. In winter, the radiation intensity will inevitably be weak, the daily duration will be short, and the general power generation will be less than in summer, which is a normal phenomenon. The distributed photovoltaic system is connected to the grid. As long as there is electricity in the grid, there will be no shortage of power and power outages for household loads.

2. Does photovoltaic power generation have radiation and pollution?

Electricity experts said: "From the current operation point of view, the solar photovoltaic system generates electricity without radiation and pollution. However, there will be problems with batteries and noise. Electronic equipment will have noise during operation, but it is within a controllable range. Batteries are similar to mobile phones and cameras. Batteries, etc. have a small dose of radiation, but it will not be a big problem." Whether there is radiation in the recycling of photovoltaic panels mainly depends on their materials. If it is crystalline silicon solar cell recycling, there are not many sources of pollution. Similarly, amorphous silicon photovoltaic solar energy products mainly depend on the choice of materials. "Some inert materials are better and less toxic."

3. If there is continuous rain or haze after installation, will the solar photovoltaic system still work? Will there be a lack of power or a power outage?

Photovoltaic cell modules can also generate electricity under certain weak light, but due to continuous rainy or hazy weather, the solar irradiance is low, and if the operating voltage of the photovoltaic system cannot reach the starting voltage of the inverter, the system will not work. will work. The grid-connected distributed photovoltaic power generation system operates in parallel with the distribution network. When the photovoltaic system cannot meet the load demand or does not work due to cloudy days, the electricity from the grid will be automatically replenished, and there is no problem of insufficient power and power outages.

4. What are the benefits of installing photovoltaic power generation systems for industrial and commercial users?

The advantages of installing solar photovoltaic systems for industrial and commercial users include: large industrial and commercial power consumption, high electricity prices, large proportion of self-generated and self-consumption, short payback period, and high yield; in addition, photovoltaic systems have social benefits of energy saving and emission reduction, which can help industrial users to achieve energy saving and reduction. emission targets, especially in pilot cities where low-carbon trading is being carried out.
