Why Install Solar Panels on Schools?

 

The immediate attraction of school solar is usually lower electricity expenditure.

​

Every unit of solar electricity used within the school is electricity that does not need to be purchased from the grid.

​

But the advantages extend beyond energy bills.

​

The benefits of solar panels in schools can include:

​

• reducing electricity costs

• making productive use of unused roof space

• reducing exposure to future energy-price increases

• supporting school sustainability objectives

• reducing carbon emissions associated with electricity use

• providing a practical educational resource

• supporting EV charging

• working alongside battery storage

• demonstrating environmental responsibility to pupils and the wider community.

​

The Department for Education specifically identifies rooftop solar as a way to support school sustainability, while also highlighting its potential educational value for pupils learning about renewable energy and climate change.

​

​

Are Schools Good Buildings for Solar Panels?

 

Many are exceptionally well suited.

​

Primary and secondary schools often have several separate blocks with substantial pitched or flat roofs.

​

Modern school campuses may include:

​

classrooms, sports halls, dining halls, administration buildings, sixth-form centres, workshops and other buildings capable of accommodating photovoltaic panels.

​

Unlike some commercial premises, electricity use at schools is also concentrated heavily within normal daytime hours.

​

This means solar panels can be generating electricity at the same time that classrooms, computers, lighting and other equipment are operating.

​

​

How Do School Solar Panels Work?

 

Solar photovoltaic panels convert daylight into direct-current electricity.

​

The electricity passes through one or more inverters which convert it into alternating current suitable for use within the school.

​

Electricity produced by the system is normally used by the school first.

​

If electricity demand exceeds solar generation, the additional power continues to come from the grid.

​

If the panels generate more electricity than the school requires, surplus energy may potentially be exported or stored within a battery system.

​

A well-designed school solar system attempts to create a good relationship between electricity generation and the school's actual demand.

​

​

Solar Energy for Schools

 

The opportunity for solar energy for schools is substantial because education estates often contain large roof areas that currently have no productive use.

​

Installing photovoltaic panels turns those areas into electricity-generating assets.

​

A school does not necessarily need to cover every available roof.

​

The most appropriate system should take account of:

​

roof size, orientation, shading, structural capacity and the school's electricity consumption.

​

For larger schools, half-hourly electricity data can be particularly useful because it allows designers to understand when electricity is being consumed throughout the day.

​

This can then be compared with expected solar generation.

​

​

Benefits of Solar Panels in Schools

 

Reducing electricity expenditure is important, but schools can gain several additional benefits from installing solar.

​

Lower Energy Bills

Solar-generated electricity can be consumed directly within classrooms and other school buildings.

​

This reduces the amount of electricity purchased from an energy supplier.

​

The government reported in July 2026 that schools already participating in its solar programme were achieving meaningful savings, with the wider first wave expected to save an estimated £220 million over the lifetime of the panels.

​

More Predictable Energy Costs

Generating part of the school's electricity on site can reduce dependence upon fluctuating grid electricity prices.

​

The school remains connected to the electricity network, but part of its demand is supplied by the solar installation.

​

Reduced Carbon Emissions

Electricity generated directly from photovoltaic panels reduces the amount of grid electricity required by the building.

​

Solar can therefore form part of a wider school decarbonisation strategy.

​

Educational Opportunities

One of the unusual advantages of school solar is that the installation can become a teaching resource.

​

Pupils can potentially view live generation data and explore topics such as electricity, renewable energy, climate change and sustainability.

​

The Department for Education's solar procurement framework specifically identifies educational opportunities for pupils as one of the benefits of school solar installations.

​

Visible Environmental Leadership

Solar panels provide a highly visible demonstration of environmental investment.

​

For schools developing sustainability strategies, this can help engage pupils, staff, parents and the wider community.

​

​

Government Solar Panels for Schools Programme

 

Government support for school solar has expanded considerably.

​

As of July 2026, the government reported that 245 schools and colleges already had government-funded solar panels, with a further 100 joining the Great British Energy Solar Partnership through up to £40 million of additional government backing.

​

The programme forms part of a wider Great British Energy investment supporting solar installations across schools, colleges and other public-sector buildings.

​

This makes school solar a particularly active area of public investment.

​

​

Solar Panels for Schools Grants

 

Schools searching for solar panels for schools grants should be aware that funding arrangements change frequently.

​

There is not simply one permanent grant available to every school.

​

Funding can depend upon:

​

the type of school, its location, the responsible local authority or academy trust, the programme currently open and the particular energy improvements proposed.

​

Current routes include government-backed solar programmes as well as broader public-sector decarbonisation initiatives and locally administered schemes. The Public Sector Decarbonisation Scheme has also funded projects where schools receive solar PV alongside other building energy improvements.

​

Schools should therefore check the current position before assuming that a particular grant remains available.

​

​

Solar Grants for Schools

 

The phrase solar grants for schools can cover several different types of financial support.

​

Some schemes provide direct capital funding.

​

Others form part of wider programmes covering measures such as:

​

solar photovoltaic panels, LED lighting, insulation, heat pumps and building energy-management systems.

​

There can also be regional or local funding initiatives.

​

For example, some councils have created their own school energy-efficiency programmes that include solar PV. Funding therefore needs to be investigated for the individual school rather than treated as a single national entitlement.

​

​

Free Solar Panels for Schools

 

Schools may also encounter offers described as free solar panels for schools.

​

It is important to understand exactly what "free" means.

​

A system may genuinely involve no upfront capital expenditure but still operate under a commercial agreement.

​

One increasingly important model is a Power Purchase Agreement, commonly known as a PPA.

​

Under a PPA, a third-party provider can finance, install, own and maintain the solar panels. The school then purchases the electricity generated by the system under an agreed contract.

​

The Department for Education launched a PPA pilot in July 2026 involving up to 150 schools and colleges. Under the pilot, private-sector investment funds installation and maintenance without an upfront payment from the school, while participating establishments buy the generated electricity at an agreed rate.

​

So "free solar" should not automatically be understood as ownership of a solar installation being given away without conditions.

​

Schools should carefully examine the contract, energy price, term, maintenance arrangements and ownership provisions.

​

​

Solar Power Purchase Agreements for Schools

 

A PPA can provide an alternative where a school wants the benefits of solar but does not have sufficient capital to purchase an installation outright.

​

Instead of buying the equipment, the school effectively agrees to purchase electricity generated by equipment owned by another organisation.

​

This can remove substantial upfront expenditure.

​

The Department for Education has said that its current pilot is intended to help establish a route through which schools and colleges could access privately financed renewable energy more widely from the 2027–28 financial year.

​

For some schools this could significantly change the financial case for solar.

​

​

Buying Solar Panels Outright

 

The alternative is for the school, academy trust, local authority or other responsible body to purchase the system.

​

This involves greater initial expenditure but means the organisation generally retains ownership of the equipment and the electricity it produces.

​

The best option depends upon available capital, financing, energy consumption and the terms offered through alternative funding arrangements.

​

Financial comparisons should therefore consider the entire operating life of the installation rather than simply the initial price.

​

​

Solar Panels for Schools Cost

 

There is no single solar panels for schools cost because education buildings vary enormously.

​

A small village primary school could require a relatively modest installation.

​

A large secondary school, academy campus or further-education college could potentially accommodate hundreds of panels.

​

Cost is affected by factors including:

​

• size of the solar array

• number and specification of panels

• inverter equipment

• roof construction

• roof condition

• access and scaffolding

• structural requirements

• electrical works

• monitoring systems

• battery storage

• project management.

​

The cost should therefore be considered alongside expected generation and electricity savings.

​

​

How Many Solar Panels Does a School Need?

 

The number of panels should be determined by more than available roof space.

​

A competent designer should examine how much electricity the school uses and when it is used.

​

A school with large kitchens, extensive IT infrastructure, workshops or sports facilities may consume considerably more electricity than another school of similar physical size.

​

The objective is to create an installation that provides useful generation without unnecessarily oversizing the system.

​

​

School Electricity Consumption

 

Schools can contain a surprisingly diverse range of electrical loads.

​

These may include:

​

classroom lighting, computers, interactive displays, servers, kitchens, refrigeration, ventilation, pumps, lifts, sports facilities and administration equipment.

​

Some schools also operate specialist workshops, laboratories, swimming pools or performance facilities.

​

Understanding these loads is important when designing the solar system.

​

The Department for Education's energy-efficiency guidance encourages schools and colleges to understand and manage their energy demand as part of reducing costs and carbon emissions.

​

​

Solar Panels for Primary Schools

 

Primary schools can often provide good opportunities for photovoltaic installations.

​

Their electricity demand may be lower than a large secondary school, but many primary schools have substantial pitched or flat roofs.

​

A solar installation can provide electricity for:

​

classrooms, lighting, IT equipment, kitchens and administration areas.

​

The system can also become particularly useful educationally because younger pupils can see renewable-energy technology operating on their own school.

​

​

Solar Panels for Secondary Schools

 

Secondary schools typically consume more electricity and have larger sites.

​

They may include:

​

sports halls, laboratories, workshops, kitchens, ICT suites and extensive classroom accommodation.

​

This combination of larger roof areas and greater electricity demand can make substantial solar installations possible.

​

Some government-supported secondary school projects are already combining solar panels with measures such as LED lighting to reduce overall energy expenditure.

​

​

Solar Panels for Colleges

 

Further-education colleges can present opportunities similar to large commercial buildings.

​

Campuses may contain substantial roof areas and operate throughout much of the day.

​

Workshops, engineering facilities, catering departments, laboratories, computing centres and other specialist teaching environments can create substantial electrical demand.

​

Solar can therefore potentially form a significant element of a college's energy strategy.

​

​

Flat Roof Solar Panels for Schools

 

Many schools constructed from the mid-twentieth century onwards contain significant areas of flat roof.

​

These can be ideal for photovoltaic installations.

​

Panels are generally mounted on proprietary frames that establish an appropriate inclination.

​

The design needs to consider:

​

rooflights, drainage outlets, ventilation equipment, access routes and shading between rows of panels.

​

Some mounting systems use ballast rather than penetrating the roof membrane.

​

Where ballast is proposed, the additional structural load needs to be considered carefully.

​

​

Solar Panels on Pitched School Roofs

 

Traditional schools may have extensive pitched roofs finished with tiles, slate or other materials.

​

Photovoltaic panels can often be installed using rails and brackets connected back to the supporting structure.

​

The fixing method must be appropriate to the roof construction and maintain its weather resistance.

​

Historic buildings may require a more sensitive design approach, particularly where panels would affect important elevations.

​

​

Structural Assessment

 

Before installing a large solar array on a school, the existing roof structure should be assessed.

​

Panels introduce additional permanent loading, while wind forces acting on the array also need to be considered.

​

Older school buildings can contain a mixture of construction types resulting from decades of extensions and alterations.

​

One roof may be perfectly suitable while another part of the same school requires strengthening or is unsuitable for solar.

​

Structural considerations should therefore be addressed before the final panel layout is confirmed.

​

​

Roof Condition

 

The remaining life of the roof is another important issue.

​

Solar panels may remain in position for decades.

​

Installing them onto a roof that requires major replacement in the near future could mean paying to remove and reinstall the panels later.

​

The roof condition should therefore form part of the initial assessment.

​

Where significant roofing works are already planned, coordinating the roof replacement and solar installation can make practical sense.

​

​

Asbestos and Older School Roofs

 

Some older educational buildings may contain asbestos-containing materials.

​

Where this is known or suspected, appropriate surveys and management procedures will be required before installation work affects the roof.

​

Solar contractors should not simply assume that an older roof can be drilled or disturbed.

​

The school's asbestos register and relevant survey information should be considered when planning the works.

​

​

School Solar Panels and Battery Storage

 

Battery storage can be incorporated into some school solar systems.

​

Electricity generated during periods of lower demand can potentially be stored and used later.

​

Whether batteries provide good value depends upon the school's consumption pattern.

​

Most schools already consume significant electricity during solar-generating hours, which can reduce the amount of surplus electricity available for storage.

​

However, batteries may become more attractive where buildings have:

​

evening activities, sports facilities, extended opening hours or substantial electricity demand after pupils leave.

​

The battery should therefore be assessed as part of the overall energy strategy rather than automatically added to every solar system.

​

​

Solar Panels and School EV Charging

 

Schools are increasingly installing electric vehicle charging facilities for staff, visitors or fleet vehicles.

​

Solar electricity can contribute towards this additional demand.

​

Where vehicles remain parked on school grounds throughout the day, charging can coincide particularly well with solar generation.

​

The solar system and EV infrastructure can therefore be designed together.

​

​

Solar Carports for Schools

 

Schools with significant parking areas may also consider solar carports.

​

Panels are mounted onto purpose-built canopies above parking spaces.

​

This allows the school to generate additional electricity without relying entirely upon building roofs.

​

Solar carports can also provide shelter for vehicles and integrate naturally with EV charging.

​

They may be particularly useful where school roofs are heavily shaded, structurally unsuitable or already occupied by plant.

​

​

Solar Panels and School Air Conditioning

 

Where schools operate air-conditioning or mechanical cooling, solar can provide part of the electricity required.

​

Cooling demand tends to increase during warmer, brighter weather.

​

This means periods of high air-conditioning demand can coincide with strong solar generation.

​

The relationship can make solar particularly useful for schools containing specialist facilities requiring mechanical cooling.

​

​

Planning Permission for Solar Panels on Schools

 

Solar panels on schools are treated as non-domestic installations for planning purposes.

​

There are permitted development rights for certain solar equipment on non-domestic buildings in England, but these contain limitations and conditions. Whether a particular school installation requires planning permission depends upon the building, panel arrangement, location and any relevant designations.

​

Special consideration may be required for:

listed schools, conservation areas, prominent historic buildings or unusually large installations.

​

Planning should therefore be checked during the design stage.

​

​

Listed School Buildings and Solar Panels

 

Historic schools can sometimes accommodate solar, but installation requires more careful consideration.

​

The significance of the building, roof visibility, fixing methods and impact upon historic fabric may all influence what is acceptable.

​

A listed building may also require Listed Building Consent in addition to any planning considerations.

​

Rather than assuming solar is impossible, a sensitive assessment should identify whether less prominent roof areas or alternative locations could accommodate panels.

​

​

Solar Panels and School Fire Safety

 

Fire safety needs to form part of the design of any substantial photovoltaic installation.

​

The location of panels, electrical equipment, cabling and isolation devices should be properly considered.

​

Access for maintenance and emergency situations also needs to be maintained.

​

This is particularly important on large education buildings where rooftop plant, rooflights and multiple roof levels may already create a complicated layout.

​

​

Access and Installation During School Terms

 

Installing solar panels on an occupied school requires careful project planning.

​

Contractors may need scaffolding, lifting equipment and temporary exclusion zones.

​

Schools also present particular safeguarding and access requirements.

​

For this reason, significant installation work may sometimes be programmed around school holidays.

​

However, the appropriate programme will depend upon the site, project size and contractor's working methods.

​

​

Monitoring School Solar Generation

 

Modern solar installations can provide detailed online monitoring.

​

Schools can see how much electricity their system is generating and compare output over different periods.

​

This is useful from a maintenance perspective because unusual falls in output can indicate a fault.

​

But it can also provide an educational opportunity.

​

Live solar-generation information can potentially be displayed within the school and incorporated into lessons involving science, mathematics, geography and environmental studies.

​

​

Maintaining Solar Panels on Schools

 

Solar photovoltaic systems require relatively little routine maintenance, but they should not simply be installed and forgotten.

​

Schools should understand who is responsible for:

​

monitoring, inspections, inverter faults, electrical maintenance and panel cleaning where necessary.

​

This is particularly important where the installation has been provided through a funding or PPA arrangement because maintenance responsibilities may rest with the system owner rather than the school.

​

The contract should make these responsibilities clear.

​

​

Choosing a Solar Installer for a School

 

School solar installations can be substantially more complex than ordinary residential systems.

​

The contractor may need to coordinate:

​

roof surveys, structural assessment, electrical design, access, safeguarding, planning and energy analysis.

​

Procurement requirements may also apply.

​

The Department for Education currently provides a solar photovoltaic procurement framework through its Get Help Buying for Schools service, covering equipment, installation, project management and funding solutions.

​

Schools should compare complete proposals rather than simply looking at the lowest installation price.

​

​

Comparing School Solar Quotations

 

A meaningful quotation should explain what is actually being proposed.

​

Schools should understand:

​

the number and specification of panels, system capacity, predicted annual generation, inverter specification, warranties, mounting arrangement and monitoring facilities.

​

It should also identify assumptions relating to:

​

roof condition, structural capacity, scaffolding, electrical infrastructure and grid connection.

​

Predicted savings should be based on realistic electricity consumption rather than optimistic headline figures.

​

​

Solar Panels for Academy Trusts

 

Multi-academy trusts can potentially approach solar strategically across several schools.

​

Rather than assessing each property entirely independently, a trust can review its estate and identify which schools provide the strongest opportunities.

​

Buildings can then potentially be prioritised according to:

​

roof suitability, electricity consumption, available area and likely financial return.

​

This can also make procurement and monitoring more efficient across a large estate.

​

​

Solar Panels for Independent Schools

 

Independent schools can also benefit from solar.

​

Large campuses, sports facilities, boarding accommodation and specialist teaching buildings can create considerable electricity demand.

​

Boarding schools may be particularly interesting because electricity consumption continues beyond normal teaching hours and throughout more of the year.

​

This can improve the opportunity to use solar-generated electricity directly on site.

​

​

What About School Holidays?

 

Schools have an unusual energy profile because electricity demand drops during holidays, particularly over the summer.

​

Unfortunately, summer is also when solar generation is strongest.

​

This needs to be considered when designing the system.

​

Schools operating sports facilities, summer programmes or other activities may continue to consume substantial electricity.

​

Otherwise, surplus generation may potentially be exported or stored.

​

This is another reason why system design should be based on actual consumption rather than simply roof size.

​

​

Are Solar Panels Worth It for Schools?

 

For many schools, yes — particularly where there is a large suitable roof and substantial daytime electricity consumption.

​

The strongest opportunity normally exists where three factors combine:

​

good roof space, strong solar exposure and useful daytime electricity demand.

​

Government investment in school solar has accelerated significantly, and in July 2026 the Department for Education announced both further publicly funded installations and a new private-finance pilot intended to expand access to solar even further.

​

That does not mean every school should automatically install the largest possible system.

​

The building, electricity demand, roof condition, funding route and long-term objectives should all be considered first.

​

​

Planning Solar Panels for a School?

 

Whether you are considering solar for a primary school, secondary school, academy, independent school or college, the project should begin with a proper assessment of the property.

​

The roof condition, structural capacity, electrical consumption, available installation area, planning position, funding opportunities and future energy requirements should all be considered.

​

Schools should also investigate solar grants for schools and current funding programmes before committing capital, because government and local funding opportunities can change.

​

APN Solar can help schools, academy trusts and education providers connect with experienced commercial solar installers who can assess the estate, develop an appropriate solar proposal and explain the available options for funding and installation.
