For schools, colleges and multi-academy trusts, rooftop solar is one of the most effective ways to reduce long-term energy costs, cut carbon emissions and gain protection from volatile electricity prices. The challenge is rarely the technology; it is how projects are funded within constrained capital budgets. What many education providers are not aware of is that government grants and low-cost public funding can be combined with solar Power Purchase Agreements (PPAs) to materially reduce the price paid for solar electricity over the long term. When structured correctly, this approach delivers immediate savings without placing additional operational burden on the school. At Green Nation, we help education estates unlock this opportunity.

Why Solar PPAs Work for the Education Sector

A rooftop solar PPA allows a third-party investor to fund, install and operate a solar PV system on a school or college roof. The education provider agrees to purchase the electricity generated on site at an agreed rate, typically for 20–25 years. This structure is particularly well suited to schools and colleges because it:

• Requires no upfront capital investment
• Delivers immediate electricity cost savings
• Provides long-term price certainty
• Transfers performance and maintenance risk away from the school
• Supports net zero and sustainability objectives.

However, PPAs do not need to rely solely on private capital.

Grants and Public Funding Available to Schools

The education sector has access to a number of government-backed funding mechanisms designed to support decarbonisation and energy efficiency.

Salix Finance

Salix provides interest-free or low-interest loans to public sector bodies, including schools and further education colleges. Where Salix funding contributes to the capital cost of a rooftop solar system, the remaining cost can be funded under a PPA, allowing the electricity price to be set at a lower level.

Public Sector Decarbonisation Scheme

The Public Sector Decarbonisation Scheme offers grant funding to support public sector bodies in reducing emissions from their estates. Rooftop solar is often a strong component of successful applications, particularly when aligned with wider energy efficiency or heat decarbonisation measures.

Department for Education

From time to time, the Department for Education supports targeted capital and sustainability funding initiatives. These can be especially relevant for multi-academy trusts seeking to deliver solar across multiple sites in a coordinated programme.

How Funding Can Reduce PPA Electricity Prices

When grant funding or low-cost public finance is applied to a solar project, the impact is straightforward but powerful. The total capital required from the PPA investor is reduced. The project risk profile remains unchanged. The long-term PPA electricity rate falls.

In practical terms, this means schools can secure:

• Lower pence-per-kilowatt-hour PPA rates
• Greater savings versus grid electricity
• Improved affordability for budget-constrained sites

This blended funding approach often turns a “good” solar project into a clearly compelling financial decision.

How Green Nation Supports Schools and Colleges

Green Nation works with schools, colleges and trusts as a long-term delivery partner, not just a solar installer. Our role includes:

• Assessing rooftops and matching system size to on-site demand
• Identifying eligibility for grants, loans and public funding
• Structuring PPAs that reflect any grant or subsidised funding input
• Managing design, construction and long-term operation
• Ensuring compliance with public sector governance and procurement requirements

Our focus is on delivering robust, long-life assets that perform reliably and provide predictable savings over decades.

A Smarter Route to Solar for Education Estates

Rooftop solar does not need to compete with other capital priorities. By combining government funding with PPA structures, schools and colleges can access clean, on-site electricity at the lowest possible long-term cost, while avoiding upfront expenditure and operational complexity.

Green Nation helps education providers understand what funding is available and how it can be used to deliver affordable, resilient and future-proof energy solutions.
