Lithium Batteries in Photovoltaic Power Generation Feasibility Applications and Core Values

Photovoltaic (PV) power generation can indeed utilize lithium batteries, which serve as pivotal energy storage components. Amid the rapid growth of wind power and strained grid scheduling, there is an urgent need for more energy storage plants to regulate peaks and frequencies. Meanwhile, industrial, commercial, and residential energy storage holds immense potential—when paired with PV power stations, it enables clean energy self-sufficiency.

Lithium batteries and related devices store electricity generated by PV systems, supplying power to loads during insufficient sunshine, nighttime, or emergencies. In recent years, the expansion of the PV industry and the rising share of renewable energy in power generation have increased grid load, leading to issues like unstable power output and high transmission losses. Additionally, European governments’ adjustments to feed-in tariff laws and cuts to subsidy policies have raised PV grid-connection costs, driving a growing demand for PV energy storage in European countries.

As energy storage devices for PV systems, advanced lithium batteries can achieve a storage efficiency of up to 95%, significantly reducing solar power generation costs. Acting as a bridge connecting the power generation, supply, and consumption sides, energy storage plays a vital role. Specifically, lithium battery energy storage systems effectively offset the randomness of renewable energy generation, enhance its absorption rate and grid stability, support distributed power, microgrids, and even the energy internet—serving as a key technology to promote the shift from fossil fuels to renewable energy as the primary energy source.
