Grosvenor Museum

Back in February, we were in the center of Chester at Grosvenor Museum installing the 38.63 kWp solar PV system. The museum decided to go solar to reduce its future energy bills and its carbon footprint as well as form part of a national program to assist the Government in achieving its 2050 net zero target. They hope that placing solar panels on its southern roof slopes will help achieve this goal.

We used 103 Longi Solar, LR4-60HPH-375M solar panels which were installed across three buildings. We connected two solar panels to every P801 optimizer and to complete the system we installed a SolarEdge 25k inverter inside the electrics room inside the museum.

The system is expected to produce around 30 MWh of energy every year and save 7 tonnes of carbon emissions which is equivalent to three hundred trees being planted. Grosvenor Museum is also looking to install six air source heat pumps on the rear roof slopes of the museum.

Grosvenor Museum

Grosvenor Museum is a museum based in the center of Chester which gives you the opportunity to explore the history of the city, its art and silver heritage, and its natural history. Find out about life during the Roman military occupation and visit the Period House, with rooms from the 17th century to the 1920s. There is a year round programme of special exhibitions and events, with an inspiring service for schools.

The Grosvenor Museum was built in 1885 to house the collections of the Chester Archaeological Society and the Chester Society of Natural Science, Literature and Art, together with schools of Science and Art. It was designed by the Chester architect Thomas Meakin Lockwood.

The museum is named after Hugh Lupus Grosvenor, 1st Duke of Westminster, who donated a portion of the site in Grosvenor Street and part of the building costs; the rest of the costs were met by public appeal.

At the rear of the museum you will find 20 Castle Street, the Museum’s Period House. The house was built around 1680 and its staircase with ‘barley sugar’ banisters dates from this time. It has been part of the Grosvenor Museum since 1955 and is now displayed as a sequence of nine period rooms dated from 1680 to 1925.
