Solar PV for offices
Solar panels for offices — daytime demand, ESG-aligned
MCS-certified commercial solar PV for office buildings across the North East. 9-to-5 demand profile matches solar generation almost perfectly. Strong ESG-reporting fit. Pairs naturally with workplace EV charging for staff and visitors.
Why office solar pays back even faster than residential
Office demand profiles are heavily skewed to working hours (typically 7am-7pm Monday-Friday), which lines up almost perfectly with solar PV generation. Self-consumption rates of 65-80% are typical for mid-size offices, with the rest exported at SEG or wholesale rates depending on contract.
Office tenants also face the most direct ESG pressure of any commercial property type. Tenders, B Corp recertification, GHG Protocol Scope 2 disclosure and procurement-side carbon questionnaires all increasingly require on-site renewable generation evidence. Solar PV plus a Scope 2 verified annual report addresses the question definitively.

Office solar cost
Indicative cost by office size
| Office type | Staff / floor area | System size | Indicative cost | Annual saving |
|---|---|---|---|---|
| Small professional services office | 10-30 staff / 400 m² | 15-30kW | £14,000-£28,000 | £3,500-£7,000 |
| Mid-size HQ or single tenant | 30-100 staff / 1,500 m² | 50-100kW | £42,000-£90,000 | £11,000-£24,000 |
| Large HQ / multi-tenant office park | 100-500 staff / 5,000 m² | 150-350kW | £120,000-£275,000 | £32,000-£75,000 |
| Corporate campus | 500+ staff / 10,000+ m² | 400kW+ | Bespoke | Bespoke |
ESG and procurement
Why offices increasingly need solar to win contracts
Three procurement-side trends are pushing office solar from optional to expected:
We provide annual generation reports, MCS certificates, BEIS-aligned carbon avoidance figures and GHG-Protocol-mapped Scope 2 disclosure templates as part of every commercial solar handover.
Solar + workplace EV charging
Office solar's natural pairing
Solar generation peaks during the working day. Office EV charging demand peaks during the working day. The two overlap almost perfectly — staff plug in at 9am, the solar array generates through 11am-3pm, and the chargers are powered from the roof rather than from the grid.
For offices already considering both solar and workplace EV charging, the integrated install costs 15-25% less than two sequential projects because the electrical infrastructure (G99 application, switchgear, cabling) is shared. We typically scope both as a single project.
For details on the EV charging side, see our workplace EV charging page.
