Hotels and care homes share one characteristic that makes them outstanding candidates for commercial solar: they never switch off. 24/7 electricity consumption from lighting, heating systems, air conditioning, laundry, kitchen equipment and medical devices means that virtually all generated solar electricity is consumed on-site. Combined with battery storage, Cardiff hotels and care homes can achieve self-consumption rates of 85–95% — among the highest of any commercial property type.
Why Hotels & Care Homes Get Outstanding Solar Returns
Hotels and care homes use electricity day and night — laundry, air conditioning, heating and lighting run constantly. Solar plus battery storage serves the full 24-hour demand.
85–95% of generated solar is typically consumed on-site by Cardiff hotels and care homes. This means maximum savings and minimal export.
A 50-bed Cardiff care home might spend £80,000–£150,000 per year on electricity. Solar can cut this by 50–60%, creating savings of £40,000–£90,000 per year.
Commercial battery storage extends solar benefit through the night, maximising self-consumption and providing backup power security for critical care equipment.

Planning Considerations for Cardiff Hotels & Care Homes
Cardiff has many hotels and care homes in conservation areas, including some listed buildings. We have extensive experience navigating the planning process for solar installations on heritage buildings. Key considerations include:
Battery Storage for Cardiff Hotels & Care Homes
We strongly recommend battery storage alongside solar for Cardiff hotels and care homes. The reasons are compelling: extending solar benefit through the night, reducing peak demand charges, providing critical power resilience for care equipment, and demonstrating energy independence to CQC inspectors who increasingly value energy security in care home operations.
A typical Cardiff care home with a 40kW solar array and 30kWh battery storage will cover approximately 65% of its total annual electricity consumption from solar, compared to 45% without storage. The additional cost of battery storage (£8,000–£15,000 for commercial units) is typically recovered within 3–4 years through additional savings and peak demand charge reductions.
