Sungrow, a global leader in inverter solution supplier for renewables, recently connected its 27.5MW/30MWh solar-plus-storage project to the National Grid. Around 10,000 households can now expect their total annual energy consumption to come from this solar plant outside of Yorkshire.

A leap forward for the UK solar sector

This combined solar and storage pipeline was broken ground in spring 2019 and completed last month. The UK solar sector leaped forward through the commissioning of this project. Standing as the country's largest utility-scale subsidy-free solar-plus-storage system, it shows a significant opportunity for the next phase of growth for the solar market.

Apart from being the UK's to date largest subsidy-free solar-plus-storage system, it's also the UK's first government project to achieve 100 percent clean energy.

"This game-changing solar-plus-storage project provides industry a viable pipeline in addressing the challenges of the energy transition while supporting clean energy innovation and saving money on energy bills," says Andrew Lycett, General Manager of Sungrow UK.

State-of-the-art system

The project utilizes Sungrow's integrated solar-plus-storage solution, consisting of 1500Vdc PV turnkey solution SG3125HV-MV, all-in-one ESS SC2500HV-MV and Samsung SDI Mega M2F battery modules. Sungrow's high performing PCS SC2500HV-MV lies in its ability to deliver high efficiency and compatible with high voltage battery systems. This, in turn, improves yields and reduces operations and maintenance costs. Combined with bifacial panels and single-axis trackers, the system can contribute approximately 20 percent increase in power generation.

The solar plant will store the excess energy in Sungrow's advanced lithium-ion battery system to get more advantageous pricing for its output. Another advantage of this setup is that it allows the solar plant to provide a grid balancing service to the National Grid.
