The first hurdle is the interplay of technologies themselves. The core advantage of lithium-ion batteries is their high energy density. But this very advantage also puts them inherently in a tug-of-war between efficiency and safety.

As batteries continuously strive for higher energy density, their internal stability is compromised. Once exposed to overcharging, short circuits, external impacts, or high temperatures, the internal temperature of the cell rises rapidly, triggering a series of irreversible exothermic reactions—what the industry calls "thermal runaway."

Starting April 1st, export tax rebates for photovoltaic (PV) products will be officially cancelled, marking the end of the long-standing era of PV subsidies.

According to Announcement No. 2 of 2026 issued by the Ministry of Finance and the State Taxation Administration on January 9th, starting April 1st this year, the VAT export tax rebate rate for 249 PV products, including solar cells, modules, and doped silicon wafers, will be reduced from 9% to 0%. The rebate rate for battery products will be cancelled in two phases: first reduced to 6%, and then completely cancelled from January 1st, 2027, allowing companies time to adapt.

Predicting the value of PV equipment in two decades time is one of the key difficulties of estimating costs of retiring a solar plant.PV recycling capacity in Europe is lagging behind forecast waste volumes over the coming decades, according to a new study.

According to data from Intertek CEA, the current price increase of solar photovoltaic modules is mainly affected by the following five key factors: silver, polysilicon, glass, water and energy, and aluminum.

The "wind-solar-storage-charging" smart energy integrated demonstration charging station in the High-tech Zone has officially started operation, with a total of 9 charging spaces. Unlike traditional charging stations, this integrated demonstration station combines the advantages of green energy and energy storage. The entire system consists of three parts: wind and solar green energy, energy storage, and charging piles. Combined with the energy management and control system, it achieves multi-energy complementarity, stable and efficient, and green and environmentally friendly energy utilization.

In the summer of 2025, a research team from Western University in Canada completed a groundbreaking experiment in an exceptionally hot outdoor environment—growing organic romaine lettuce under the shade of 13 different photovoltaic modules. They found that the lettuce yield under cadmium telluride thin-film photovoltaic modules was more than 400% higher than the unshaded control group and 200% higher than the national average yield in a typical local year!

Data shows that Spain's newly installed self-consumption photovoltaic (PV) system capacity in 2025 totaled 1,139 MW, a 3.7% decrease compared to 2024. This brought Spain's total self-consumption PV capacity to 9.3 GW.

According to a solar researcher at Rystad Energy, the cost of manufacturing solar modules in China will rise in the first half of 2026, although module prices may fall again before the end of the year.

Photovoltaic heating offers a new solution to this problem. It retains the advantages of electric heating—cleanliness and convenience—while significantly reducing operating costs by utilizing free solar power.

With the rapid development of renewable energy, energy storage technology, as a key means to address the imbalance between energy supply and demand and ensure the stable operation of the power grid, is gradually receiving widespread attention.

Energy Management Systems (EMS), as a core component, are playing an increasingly important role. This article will provide an in-depth introduction to the composition of energy storage EMS systems.
