Data centres
Commercial solar for data centres
Data centres run a large, constant load around the clock and face intense pressure to prove sustainable operation.
Data centres run a large, constant load around the clock and face intense pressure to prove sustainable operation. On-site solar PV and battery storage reduce grid demand and support carbon targets — and can be funded with no upfront cost.
A data centre’s base load never sleeps, so any on-site generation is consumed immediately and continuously. While solar cannot cover a 24/7 load alone, it meaningfully offsets daytime draw and demonstrates measurable progress on renewable sourcing.
Battery storage complements existing resilience infrastructure and helps manage peak demand and capacity costs, while a PPA or lease keeps the investment off the balance sheet.
Why it fits
Why data centres suit solar & battery
Constant, high self-use
A 24/7 base load means every kilowatt of solar is used on site the moment it is generated.
Sustainability that is audited
Clients and regulators scrutinise data-centre energy; on-site renewables are a clear, reportable reduction.
Peak and capacity management
Battery storage supports demand management alongside your existing UPS and backup systems.
Off-balance-sheet options
A PPA or operating lease funds the system without capital outlay, preserving budget for core infrastructure.
Fund it your way
Zero upfront, or own it outright
Most data centres choose a PPA for zero upfront cost and a fully managed system. If you would rather own the asset and claim the tax benefits, hire purchase or outright purchase (CapEx) may suit you better.
Questions
Data centres solar FAQs
Can solar realistically power a 24/7 data centre?
Not on its own — but it offsets a valuable share of daytime demand and, with battery storage and smart tariffs, contributes around the clock. It is best seen as one part of a broader renewable-sourcing strategy.
Does battery storage interfere with our UPS/backup?
No. A commercial battery system is designed to complement, not replace, your resilience infrastructure — supporting demand management and peak-cost reduction.
