LONGi releases world's first anti-dust solar panel

According to the data published by the National Energy Administration, the total installed capacity of photovoltaic (PV) power generation in the first half of 2023 reached 78.42 GW, with distributed PV reaching 40.96 GW, surpassing centralized PV for the first time.

With the rapid development of the PV industry, the differences between distributed and centralized business scenarios have become increasingly significant, leading to different demands for products.

As a leading global solar technology company, LONGi conducted a "2022 Global Customer Satisfaction Survey" which revealed that 80.13% of commercial and industrial establishments suffer from the problem of dust accumulation on solar panels. This dust reduces the efficiency of the panels significantly. The company's laboratory also conducted a test on the effect of dust accumulation, showing that a 90mm strip of dust could lead to a 23.39% decrease in power output.

On October 8th, LONGi announced the release of the LONGi Distributed Hi-MO X6 high-efficiency anti-dust solar panel, which is the world's first anti-dust PV product.

Zhong Baoshen, chairman of LONGi, said that the Hi-MO X6 anti-dust solar panel adopts the company's self-developed HPBC (Heterojunction with Passivated Back Contact) technology. It has four main features: aesthetics, high power generation efficiency, safety, and anti-dust. Most importantly, the innovative frame design allows the solar panel to effectively utilize rainwater to wash away dust, solving the long-existing problem of dust accumulation in the distributed PV market.

Comparative data shows that solar panels with anti-dust features can achieve a power generation gain of 2.04%, with a maximum gain of up to 6%. Calculations based on a 10,000 square meter roof estimation indicate that the LONGi Hi-MO X6 anti-dust solar panels can generate an additional 3 million kWh of electricity over a 25-year period.

"Necessary changes may seem small, but the technical difficulties are significant, and strict process requirements must be met. It took our team over a year and thousands of experiments to succeed in solving the problem of dust accumulation," said Niu Yanyan, president of LONGi's Distributed Business Group in China.

Distributed PV, especially residential PV, often installs panels on rooftops, making the cleaning process challenging. This innovation not only reduces power generation losses caused by water and dust accumulation but also reduces the frequency of panel cleaning for homeowners, ensuring their profitability.
