RELEASE: 10 tips to mitigate the impact of the 'ring of fire' eclipse on solar energy

SHANGHAI, Oct. 10, 2023 /PRNewswire/ -- As the United States eagerly anticipates the next annular solar eclipse, which will occur on Saturday, October 14, after an absence of 11 years, it will have a direct impact on the energy production of photovoltaic (PV) solar plants. Ahead of this momentous occasion, Qn-SOLAR, a leading PV manufacturer, offers effective strategies to minimize the adverse effects of solar eclipses on PV power generation.

According to NASA, the annular solar eclipse, also known as the 'ring of fire,' begins in Oregon at 9:13 a.m. PT and ends in Texas at 12:03 p.m. CT. An annular solar eclipse occurs when the Moon is at or near its farthest point from Earth, appearing slightly smaller than the Sun, so it does not block the entire solar disk.

Solar eclipses pose a significant challenge to solar power generation, as decreasing irradiance directly affects the output of solar energy systems. As the eclipse progresses, solar generation decreases in proportion to the impact on irradiance, creating a temporary deficit in energy production.

As a key player in the photovoltaic industry, Qn-SOLAR has summarized 10 key takeaways to reduce the impact on solar power generation.

1. Energy storage

Before a solar eclipse, grid operators can increase their energy reserves by expanding the capacity of battery energy storage systems. Qn-SOLAR had already completed 15 GW installations and owned 1.5 GW power plants in 2022.

2. Smart grid

By incorporating smart grid technologies, grid operators can effectively manage and distribute electrical resources with greater precision and automatically adjust power supply and demand to ensure grid stability.

3. Diversified energy structure

A diverse energy structure with wind, hydroelectric and thermal energy can compensate for the decrease in solar energy generation during an eclipse. Additionally, the progress of distributed generation and microgrid technologies strengthens the grid's ability to withstand disruptions. Qn-SOLAR started photovoltaics in 2014, wind energy in 2020, and energy storage in 2023.

4. Dynamic programming

Grid operators can monitor eclipses in real time and adjust generation plans and power dispatch accordingly, minimizing the impact on the grid. Furthermore, early warnings allow adequate preparations to be made in advance.

5. Flexible resource submission

Flexible dispatching of various power generation resources, such as quick-start gas turbines, hydroelectric plants, and energy storage systems, helps manage power fluctuations.

6. Demand side management

Implementing demand-side management strategies, such as time-of-use pricing and emergency peak shaving, encourages users to adjust their electricity consumption, reducing power demand during the eclipse.

7. Smart programming algorithms

By leveraging advanced intelligent scheduling algorithms, such as particle swarm optimization and genetic algorithms, dynamic optimization and grid scheduling can be achieved, improving the efficiency of power system operations.

8. Scientific prediction

The combination of an integrated meteorological observation and astronomical forecasting system allows for more accurate forecasts of the timing, location and magnitude of the eclipse, providing precise decision-making guidance for network dispatch.

9. Virtual power plant technology development

The integration of various distributed generation resources through virtual power plant technology creates a controllable and manageable power generation unit, thereby improving the operational stability of the grid.

10. Improved network interconnection

Strengthening interconnections between networks facilitates the complementarity of resources and optimal allocation, improving the general operational stability of the electrical system.

In particular, the above solutions can greatly reduce the impact, but cannot completely eliminate it.
