In Aangren County, a Tibetan plateau area with an average altitude of 4,500m, SolarEast technical team, braving the howling and biting cold wind, have been working for days on a project, where one can see sunshine glows settle on arrays of photovoltaic panels lined up on school roofs under the blue sky and white clouds. Powered by solar energy, the energy storage system is charging itself up and poised to supply power to the air-source heat pumps, which are running quietly and delivering warmth that teachers and students are long waiting for. This is a PV + Energy Storage + Heat Pump Project that warms the school up and renders district heating in Tibet possible.
A couple of SolarEast workers, regardless of obstacles and threats posed by frozen soil, heavy wind, and mechanical efficiency reduction on plateau, finalized the project within 20 days that could realize full-capacity power generation, energy storage and all-weather heating supply with heat pumps.
Characterized by less sources of conventional power supply and severe reliance on hydropower, Tibetan Grid always faces tight power supply in winter dry season. To satisfy the demand of local schools for clean energy heating, SolarEast PV and ESS design team, giving full play to the local advantage of abundant solar energy resources, worked out a comprehensive heating solution featuring integration of PV with energy storage system and heat pumps. The project specifically built for 17 schools solves the heating problem once for all confronting the schools and contributes to local power supply guarantee initiative in winter after putting into operation.
Located 4,513m above sea level and with an average temperature of 6.5℃ in winter, Angren County is known for harsh climates of perennially windiness, coldness and semiarid, therefore needing extreme high performance of energy storage products in terms of safety and reliability.
Given these atrocious conditions, SolarEast adopted its own thermal system that has been well proven under such extreme atmospheres as coldness, high altitude and high humidity. Furthermore, SolarEast specifically designed the PCS, which features bigger power output, smaller size and higher cost-efficiency that is conductive to installation, commissioning and maintenance on site. Through remote monitoring system, Operation & Maintenance staff can get access to real-time system running data and identify hidden risks in a proactive manner, therefore saving troubleshooting time, reducing resource input and improving system efficiency. In addition, the system can also realize data analysis that underpins subsequent system upgrade.
