Can a 1kW182 module generate 1500 kWh of electricity in a year?
Answer: This is achievable in two scenarios: 1. In regions where the annual equivalent utilization hours are greater than 1500 hours. 2. In regions where the annual equivalent utilization hours are less than 1500 hours, tracking supports or other auxiliary technologies can be used.
What is the maximum size of lithium batteries that can be connected to a 10kW energy storage inverter? Is the inverter equipped with lithium batteries?
Answer: The battery for a 10kW energy storage inverter needs to be selected separately, and the maximum capacity for energy storage batteries is 20kWh.
What suggestions do you have for lightning protection for the entire system?
Answer: Lightning protection for the system includes direct lightning strikes and induced lightning strikes. Direct lightning strikes can be prevented by using the metal frame of the photovoltaic module, supports, and the metal components of the original building structure as grounding devices. Induced lightning strikes can be prevented by using equipotential connections, magnetic shielding, and installing SPDs.
If a distributed photovoltaic power station is built together with a 4G/5G transmission base station (without reflection), will it affect power generation? Will it attract more lightning strikes?
Answer: Due to the special nature of the base station, it needs to be built at a high point. Photovoltaic power generation is one of the multiple complementary energy sources for powering base station equipment. There are many factors that affect photovoltaic power generation, such as the orientation and angle of the modules, line loss, spacing, shading, etc. The base station is just a load for the photovoltaic power station and does not affect power generation. Even if there is no load, it will not affect power generation.
The photovoltaic power station is not the highest point, the lightning rod on the top of the base station is the highest point, and the lightning rod will lead the lightning charge underground. The photovoltaic power station together with the base station will not actively attract lightning strikes, but will be protected against lightning strikes through grounding, SPDs, etc.
How much does the angle between the module and the horizontal plane affect power generation efficiency?
Answer: The impact of the angle between the module and the horizontal plane on power generation efficiency varies depending on the latitude and longitude of the region. Taking Jinan as an example (facing due south, under the same conditions, the optimal inclination angle is 30 degrees, without loss of power generation), if the inclination angle is 50 degrees, the power generation loss is 4%; if the inclination angle is 40 degrees, the power generation loss is 0.9%; if the inclination angle is 20 degrees, the power generation loss is 1.3%; if the inclination angle is 10 degrees, the power generation loss is 4.6%.}}
