Daily Science | Advantages of photovoltaic energy storage compared to diesel power generation

In the field of energy, photovoltaic energy storage and diesel power generation are two common power supply methods. Today, let’s learn about the advantages of photovoltaic energy storage compared to diesel power generation.

I. Environmental aspect

Zero carbon emission: Photovoltaic energy storage uses solar energy. The entire process does not produce harmful gases and pollutants and is environmentally friendly. Diesel power generation emits a large amount of greenhouse gases and pollutants.
Low noise pollution: Photovoltaic energy storage systems operate quietly with almost no noise. Diesel generators produce relatively loud noise when operating, interfering with the surrounding environment and people’s lives.

II. Economic aspect

Low long-term cost: The initial investment in photovoltaic energy storage systems is relatively high, but the subsequent energy cost is almost zero. Diesel prices fluctuate greatly, and the long-term use cost is high.
Low maintenance cost: The maintenance of photovoltaic energy storage systems is simple, mainly including cleaning photovoltaic panels and inspecting inverters. The maintenance workload of diesel generators is large and the cost is high.

III. Energy utilization aspect

High energy self-sufficiency rate: Photovoltaic energy storage systems can achieve energy self-sufficiency in remote areas and reduce dependence on the external grid. Diesel power generation depends on diesel supply.
Improve energy utilization rate: Photovoltaic energy storage can store excess solar energy during the day and use it at night or on cloudy days, improving energy utilization. Diesel generators have low efficiency and waste energy when operating at low loads.

IV. Power supply stability aspect

Not affected by fuel supply: Photovoltaic energy storage can generate power and store electrical energy as long as there is sunlight and is not limited by fuel supply. Diesel power generation will be affected if the diesel supply is interrupted.
Better response to grid fluctuations: Photovoltaic energy storage can peak-shave and valley-fill, alleviate the load pressure on the grid, reduce fluctuations, and improve power supply stability.

V. Sustainable development aspect

In line with energy development trends: As a clean energy solution, photovoltaic energy storage is widely supported by the government and society. Diesel power generation faces pressure from environmental protection policies and energy transformation.

Choosing photovoltaic energy storage contributes to our environment and future.
