Core Case

The second phase of the Huadian Tibet Caipeng SolarStorage Power Station has commenced operation at an altitude of 5,228 meters. It features 250,000 photovoltaic panels with a total installed capacity of 100,000 kilowatts, and receives annual average solar radiation more than double that of plain areas at the same latitude. Once operational, the second phase is expected to generate 155 million kilowatt-hours of electricity annually, meeting the electricity needs of 50,000 households and reducing carbon dioxide emissions by 101,800 tons annually. The project utilizes next-generation bifacial solar panels, increasing power generation efficiency by 7.5%. The energy storage system, comprised of 16 white boxes, acts like a giant “power bank,” storing electricity during the day and delivering it at night, ensuring grid stability and security and serving as a model for clean energy utilization in high-altitude areas.

Yanjiang Village in Xincheng Town, Yizheng City, Yangzhou, Jiangsu Province, a national permanent farmland conservation area, began its green energy transformation in 2024. On December 25, 2023, Jiangsu Province’s first energy cooperative, the Yizheng Xuzhong Energy Cooperative, was established. Villager Liu Hongxi installed 72 solar photovoltaic panels and received an initial installation fee of 14,400 yuan. He also received 50 yuan in rental income per panel every quarter, bringing his annual income to over 10,000 yuan. To date, the cooperative has 103 participating households, with an installed capacity of 2.8 megawatts, generating over 1 million yuan in cumulative revenue for the villagers. The cooperative plans to increase its installed capacity to 4 megawatts by 2025, benefiting even more  villagers.

Dorina and her family, living in Bristol, signed up for Sunsave Plus to install solar panels in March 2025. Since installation, they’ve saved approximately £50 on their monthly energy bills (after deducting the Sunsave Plus fee). Over the next 20 years, they estimate this will translate to approximately £30,000 in savings. Choosing solar panels not only reduces long-term costs and protects against inflation, but also improves their home’s EPC rating and value. Sunsave offers a 20-year, fixed price contract that covers installation, maintenance, inverter and battery replacement, giving Dorina and her family peace of mind.

Sichuan Pisheng Electronics Co., Ltd. utilized idle rooftop resources to construct a distributed photovoltaic power generation project in June 2024. Over the past year, the project has generated 1.45 million kWh of electricity, with the company using 1 million kWh for its own use and 450,000 kWh of surplus electricity connected to the grid. Furthermore, the company leveraged its technological advantages to develop a “super charger”an integrated industrial and commercial energy storage cabinet that stores photovoltaic power and can be flexibly allocated based on electricity demand. Comprehensive estimates show that the combination of photovoltaics and energy storage saves the company approximately 920,000 yuan in annual electricity bills, establishing a sustainable development path that reduces energy consumption, reduces emissions, and improves  profitability.
