Care home solar case studies
Six representative installations across the UK social care estate — residential care, nursing, dementia, hospice, extra-care, and retirement village. System sizes, savings, payback, and the lessons we'd carry forward.
Note on case study composition. Several of the case studies below are illustrative composites — combining published industry data (notably published case studies from Spirit Energy installations at B&M Care, St Michael's Hospice, and Sue Ryder-style operators) with our own engagement profile. Specific identifying details are anonymised. This approach allows us to share concrete numbers and lessons without breaching commercial confidentiality.
