117.5kW Commercial Solar Installation at Springboig Care Centre in Glasgow
The Opportunity: Solar Energy for Care Homes
Care homes are among the most energy-intensive buildings in the UK. Operating 24 hours a day, 365 days a year, they run heating, lighting, laundry, catering, medical equipment, and hot water systems around the clock — creating electricity bills that place enormous pressure on already tight operational budgets. For care home operators across Glasgow, Scotland and the wider UK, commercial solar represents one of the most effective ways to slash overheads and redirect savings towards resident care.
This residential care home in Springboig, Glasgow (G32) — located in the East End of Glasgow between Baillieston and Shettleston — presented an ideal opportunity for a large-scale solar installation. With a substantial multi-aspect roof, high annual electricity consumption of 156,499 kWh, and 24/7 operational demand, the facility was perfectly suited to a system designed for maximum self-consumption.

When the care home management approached Sol4r Energy about installing solar panels, the goal was clear: dramatically reduce the facility's electricity costs, create long-term financial stability for the business, and demonstrate a visible commitment to sustainability — increasingly important in the care sector. Using professional SAM modelling software, Sol4r Energy designed a 117.5 kWp system utilising all three available roof aspects to maximise generation throughout the day, paired with 51.84 kWh of FoxESS battery storage and 90 kW of three-phase hybrid inverter capacity.
The result: a system that offsets 57% of the care home's total electricity demand, achieves 100% self-consumption (virtually nothing is wasted to the grid), and pays for itself in just 3 years and 4 months. With projected net savings of £1,535,419 over 25 years, this is one of the most financially compelling commercial solar installations Sol4r Energy has delivered.

Tri-Aspect Roof Design — Maximising All-Day Generation
Unlike a typical installation that uses a single roof face, this care home's roof offered three usable aspects — east, south, and west — all at a 30° tilt. Sol4r Energy designed the system to utilise all three, spreading 188 panels across three groups to maximise generation throughout the entire day:
| Roof Aspect | Orientation | Panels | Peak Generation Period |
|---|---|---|---|
| East-facing array | 85° from South | 65 panels (40.6 kWp) | Morning — captures early sunlight from sunrise through midday |
| South-facing array | 5° from South | 46 panels (28.8 kWp) | Midday — highest intensity solar radiation during peak hours |
| West-facing array | 95° from South | 77 panels (48.1 kWp) | Afternoon — captures late-day generation through to evening |
This tri-aspect approach is particularly valuable for care homes and 24/7 facilities. Rather than concentrating all generation into a few peak hours, the system produces a broader, flatter generation curve that better matches the facility's constant baseload demand. The east array starts generating at sunrise when the night shift is still running and the morning routine begins. The south array peaks at midday when kitchen, laundry, and common areas are at full capacity. The west array continues generating into the late afternoon and evening when demand remains high. The result is 100% self-consumption — virtually every kilowatt-hour generated is used on-site.

Energy Performance & Self-Consumption
| Performance Metric | Result |
|---|---|
| Total installed capacity | 117.5 kWp |
| Annual solar generation | 89,727 kWh |
| Annual facility consumption | 156,499 kWh |
| Annual consumption offset | 57% — system produces over half the facility's total demand |
| kWh/kWp yield | 766.4 kWh/kWp |
| Shade factor | 0.996 — just 0.4% shading losses |
| Self-consumption rate | 100% — virtually everything generated is used on-site |
| Self-sufficiency — solar only | 30.9% |
| Self-sufficiency — solar + battery | 33.5% |
| Annual electricity exported | ~265 kWh — negligible, confirming near-total on-site consumption |
The 100% self-consumption rate is the standout metric here — and it's what makes care homes such compelling candidates for commercial solar. Because the facility consumes electricity around the clock, there's always demand to absorb whatever the panels produce. Unlike a typical business that might export significant surplus during weekends or holidays, a care home never switches off. Every kilowatt-hour generated displaces expensive grid electricity at the full import rate — maximising the financial return and delivering the fastest possible payback. For care homes, hospitals, hotels, and other 24/7 facilities across Glasgow, Edinburgh, Scotland and the wider UK, these results show what's achievable with the right system design.

Battery Benefits: Why Storage Matters for 24/7 Facilities
Why the battery makes all the difference
The 51.84 kWh FoxESS battery bank doesn't just store solar energy — it ensures the care home maximises every kilowatt-hour generated and minimises expensive grid imports during peak hours.
33.5% Grid Independence
Without batteries, solar-only self-sufficiency would be 30.9%. The 51.84 kWh FoxESS battery lifts this to 33.5% — shifting stored solar into the high-demand overnight and evening hours.
100% Self-Consumption
With 156,499 kWh of annual demand and 89,727 kWh of generation, there's always on-site load to absorb solar output. The battery ensures even brief surpluses are captured rather than exported at lower SEG rates.
Intelligent Tariff Arbitrage
Octopus Intelligent charges the battery at just 7p/kWh overnight, then the care home runs on stored energy during the 31p/kWh daytime rate. That 24p/kWh differential, applied daily, compounds into major savings.
Critical Load Protection
In a care home environment, power continuity matters. The FoxESS hybrid system provides backup capability, helping protect essential equipment during brief grid interruptions.
Night Shift Coverage
The battery bridges the gap between solar generation ending in the evening and the overnight period — powering heating, lighting, and monitoring systems from stored energy rather than peak-rate grid electricity.
Compounding Protection
With energy costs rising 7% annually, this care home's savings compound dramatically. By 2035, annual savings are projected at £48,774. By 2050, £126,160 per year — totalling £1.5M+ in net savings.
Environmental Impact
At 23 tonnes of CO₂ eliminated per year, this is one of the most impactful environmental installations Sol4r Energy has delivered. Over the system's lifetime, that's the equivalent of planting 4,387 trees or taking hundreds of cars off the road. For care home operators, the environmental credentials also support ESG reporting, sustainability expectations, and increasingly important green credentials that residents' families and commissioning bodies look for. Sol4r Energy installs commercial solar systems for care homes, hospitals, businesses, and organisations across Glasgow, Edinburgh, Scotland and nationwide.
Why Care Homes Are Ideal for Commercial Solar
Care homes are uniquely well-suited to solar energy — and this installation demonstrates exactly why. Unlike offices or retail units that sit empty overnight and at weekends, care homes consume electricity around the clock. That constant baseload creates the perfect conditions for solar to deliver maximum value:
24/7 electricity demand means virtually 100% of solar generation is consumed on-site, at the full import rate — no energy is wasted to low-value grid export. High annual consumption (this facility uses 156,499 kWh per year) means even a large system is fully absorbed, delivering the fastest possible payback. Multi-aspect roofs are common on care home buildings, enabling tri-aspect designs like this one that spread generation across the full day. Long operational lifetimes — care homes don't relocate or change use frequently, so the 25-year savings projections are highly reliable.
For care home operators, reducing energy costs directly increases the budget available for resident care, staffing, and facilities. With energy bills projected to exceed £100,000 per year within a decade at current inflation rates, a solar installation that locks in a significant portion of generation at zero marginal cost represents genuine financial security for the business.
Sol4r Energy has direct experience installing solar on care homes, nursing facilities, and healthcare buildings across the UK. We understand the unique requirements: working around vulnerable residents, maintaining access, minimising disruption, and coordinating with facility management teams.
