Yes. For many schools, academies and healthcare buildings, commercial solar is an excellent long-term investment.
These buildings use a large proportion of their electricity during the day, which is exactly when a solar PV system is generating. That puts them in a strong position to cut what they buy from the grid, improve energy resilience and get a grip on rising operating costs.
But a good outcome isn’t about fitting as many panels as possible. It comes from understanding how the building uses electricity, whether the roof is genuinely suitable, and what the organisation is trying to achieve over the long term.
Which is why every project should start with an assessment, not a system design.
Key Takeaways
- Schools, academies and healthcare buildings usually have the daytime demand that makes solar worthwhile.
- How a building uses electricity matters more than the size of its roof.
- School holidays don’t remove the value of the investment.
- Battery storage isn’t the default, but the case is shifting, and it’s now worth asking properly.
- We won’t install without a structural engineer’s green light. No exceptions.
- A detailed site survey is the only reliable way to know whether solar is right for the building.
Why Are Schools, Academies and Healthcare Buildings Often Good Candidates for Solar?
When people first enquire about commercial solar, the conversation usually starts with the roof.
We start somewhere else. The first thing we want to understand is how the building uses electricity.
Schools, academies and healthcare buildings consume most of their electricity during the day, which is when a solar PV system is producing. The more of that generation the building can use itself, the greater the saving.
It’s one reason investment across the sector is accelerating. Great British Energy has signed contracts with 255 schools across England, sharing £100 million in government-backed funding for solar and energy efficiency work, up from an initial £80 million commitment.
Why Does Daytime Electricity Demand Matter?
Two buildings can have identical roofs and deliver very different returns.
A school that’s busy all day makes far better use of the electricity it generates than a building that sits largely empty during daylight hours. That’s why we look at consumption before we discuss panel numbers.
We want to understand:
- When electricity demand is highest.
- Whether usage changes across the year.
- Whether the site is likely to expand.
- Whether future technologies such as EV charging will increase demand.
Those answers let us design a system that matches how the building actually operates, rather than installing the largest array that fits.
Good commercial solar design is about long-term value, not panel count.
Does the Roof Affect Whether Solar Is a Good Investment?
Absolutely. Roof construction, structural condition, available space and orientation all influence whether a building is suitable and how the system should be designed.
It’s also why we don’t rely on aerial imagery.
Our recent installation at the new build at The Hemel Hempstead School is a good example. The roof is a trapezoidal metal profile, which looks awkward at first glance and puts some installers off entirely.
It isn’t awkward once you know what you’re doing with it. After a full site survey and structural assessment we confirmed the roof was suitable and specified a mini-rail mounting system fixed directly to the profile crowns, no full rail framework, no unnecessary weight, and no penetration of the sheet where it matters.
The finished system is 73.7 kWp, generating around 70,000 kWh a year and saving 14 tonnes of CO2 annually. On a school with strong daytime demand, almost all of that generation gets used on site rather than exported.
Projects like that are why every building needs assessing individually. A roof that looks unsuitable from above can turn out to be an excellent candidate once someone has been up there. And a roof that looks straightforward can throw up constraints the moment it’s surveyed properly.
Do School Holidays Reduce the Value of Solar?
This is the question we’re asked most. The short answer is usually no.
Demand falls during the holidays, but it doesn’t disappear. Security systems, servers, refrigeration and emergency lighting keep running, and many schools use the holidays for maintenance, training, exams and community lettings.
Commercial solar systems are designed around how a building uses electricity across the whole year, not a few weeks in the summer. We assess annual consumption rather than making assumptions from term dates.
Why Does Solar Work Well for Healthcare Buildings?
Healthcare buildings have a different energy profile from schools, and they’re equally well suited.
GP surgeries, community healthcare sites and care homes all rely on lighting, IT, ventilation, refrigeration and specialist equipment throughout the day. That steady demand means a high proportion of solar generation gets used on site rather than exported.
The wider direction of travel is clear. Great British Energy is funding solar and battery storage across 78 NHS trusts in England, covering around 200 sites, with the projects expected to save the NHS £8.6 million a year.
Every healthcare building operates differently, so the system should always be designed around how that specific site uses electricity.
Is Battery Storage Worth It for Schools and Healthcare Buildings?
Our default position on commercial battery storage has always been a cautious one. A building running standard hours with strong daytime demand can typically achieve around 80% self-consumption without a battery. Adding one because it sounds like the complete solution is how organisations end up with capital tied up in equipment that isn’t earning.
That said, the picture is shifting, and we’d rather say so than keep repeating a line that’s going out of date.
Batteries are becoming more viable, particularly for sites operating outside typical business hours. And load shifting is becoming genuinely common. There are financial arrangements now where a business stores electricity and releases it back to the grid at peak times, earning on the difference, closer to a trading position than a straightforward bill saving.
That changes the maths. It doesn’t change it for every building.
For a primary school running term-time hours, a battery still isn’t the first thing we’d recommend. For a care home running around the clock, or an organisation with the appetite to engage with flexibility markets properly, it’s a real conversation.
The honest answer is that battery storage has gone from a question with a standard answer to one worth asking properly. We’ll tell you which side of the line your building sits on.
Which Schools and Healthcare Buildings Benefit Most from Solar?
Every project should be assessed individually, but some building types are particularly well suited.
| Building Type | Typical Suitability | Why It Works Well |
|---|---|---|
| Primary school | Excellent | Consistent daytime demand from classrooms, kitchens and administration. |
| Secondary school | Excellent | Higher demand from specialist teaching spaces, sports facilities and IT infrastructure. |
| Academy trust | Excellent | Multiple buildings allow estate-wide investment to be phased over time. |
| GP surgery | Very good | Reliable daytime demand supports strong self-consumption. |
| Community healthcare site | Excellent | Long operating hours create a consistent electrical load. |
| Care home | Excellent | Stable, round-the-clock demand supports high on-site usage, and makes battery storage worth assessing. |
Building type is only one part of the assessment. Roof suitability, structural condition and actual consumption matter just as much.
What Do We Look at Before Recommending Solar?
We assess considerably more than the available roof space.
| What We Assess | Why It Matters |
|---|---|
| Annual electricity consumption | Establishes the building’s overall demand. |
| Daytime electricity use | Indicates how much generation can be used on site. |
| Roof condition and structure | Confirms the building can safely take the system. |
| Roof construction type | Determines the mounting solution, trapezoidal profile, standing seam, membrane and tile all differ. |
| Roof orientation and available space | Influences expected system performance. |
| Existing electrical infrastructure | Ensures the system integrates safely. On larger sites this is often the most complex part of the job. |
| Future expansion plans | Allows the design to accommodate future demand. |
| Long-term estate objectives | Aligns the investment with wider operational plans. |
Why We Survey Every Site Ourselves
We don’t quote schools or healthcare buildings remotely. Anything with real intent behind it gets a physical site visit.
Part of that is the roof. Most of it is the electrical setup. We’re electricians first, our sister company has been trading B2B in commercial M&E since 2018, and on a building of this type the existing distribution, metering and earthing arrangements will shape the design as much as the roof does. On a retrofit, integrating the AC supply is frequently the hardest, and most expensive part of the whole project.
That isn’t something anyone can assess from a satellite image, and we’re not prepared to guess and then hand a bursar or estates manager a return figure built on the guess.
Would You Ever Tell Us Not to Install?
Yes. And we do. If there’s a refurbishment coming, or the structure won’t take it, then the right answer is to do the solar at the right time rather than the earliest possible time.
We will never install a system without a structural green light. Not an ‘it should be fine’. Not a ‘probably’. A structural engineer’s report confirming the building can carry it. If there’s an if or a maybe attached, we don’t proceed.
That protects you and it protects us. A roof that fails under load after installation is a far bigger problem than a project that waited six months.
We’ve assessed buildings that looked ideal from aerial imagery where structural limitations or planned refurbishment meant waiting was the better call. We’ve also seen buildings that looked difficult turn into excellent projects once they’d been surveyed properly. You don’t know until someone looks.
How Do You Know Whether Solar Is the Right Investment?
Through a proper assessment. There’s no shortcut.
Every school, academy and healthcare building uses electricity differently, has its own structural characteristics and operates to different priorities.
Before recommending a system we take the time to understand how the building runs, confirm it’s suitable and design something that reflects its long-term requirements. That gives you the confidence to make an informed investment decision rather than one based on assumptions.

Frequently Asked Questions
Can academy trusts install solar across multiple schools?
Yes. Many trusts assess several schools together, which allows projects to be prioritised and delivered in phases across the estate rather than all at once.
Can older school buildings still be suitable for commercial solar?
Yes. Age is rarely the deciding factor. Roof condition, structural integrity and electricity demand matter far more than when the building went up.
Should schools install battery storage alongside solar?
Usually not as a first step. A school running term-time hours with strong daytime demand can typically achieve around 80% self-consumption without one. A battery may still be worth assessing if the site has significant out-of-hours use or wants to explore load shifting, but it shouldn’t be assumed.
Should GP surgeries and healthcare buildings install battery storage?
It depends on the operating pattern. A surgery running standard daytime hours behaves much like a school and will often see strong self-consumption without a battery. Sites with extended hours or critical loads are a different assessment.
Should care homes install battery storage?
This is where the case is strongest. Care homes run around the clock, so demand continues long after generation stops. That out-of-hours consumption is exactly what makes storage worth modelling properly, and it’s also where newer load-shifting arrangements can add value.
What is load shifting, and can it benefit our building?
Load shifting means storing electricity when it’s cheap or self-generated and using or exporting it when prices are higher. Some organisations now enter arrangements with financial providers to release stored energy back to the grid at peak times and earn on the difference. It’s becoming more common, but it only works for certain demand profiles.
How long does it take to assess whether a building is suitable for solar?
A desktop review gives an initial indication, but a site survey is needed to assess the roof, structure and electrical infrastructure before any recommendation is made.
What information is helpful before requesting a commercial solar survey?
Recent electricity bills, annual consumption figures, half-hourly data if you have it, and details of any planned building works. If that information isn’t to hand, a site survey will identify what’s needed.
