Solar PV & Power Purchase Agreements


Reduce your carbon emissions by generating your own electricity through the power of solar energy. With climate change a major topic of concern solar initiatives are a popular strategy to significantly lower your company's carbon footprint, enhance your reputation and increase your company’s sustainability credentials.

Generating electricity with solar power instead of fossil fuels dramatically reduces greenhouse gas emissions, particularly carbon dioxide (CO2). Greenhouse gases, which are produced when fossil fuels are burned, lead to rising global temperatures and climate change. Climate change already contributes to public health and serious environmental issues including extreme weather events, ecosystem changes and rising sea levels.

By going solar, you can limit greenhouse gas emissions, reduce demand for fossil fuels and shrink your carbon footprint. One business installing a solar energy system can have a measurable effect on the environment.  A typical system will deliver CO2 reductions of circa 60 tonnes a year.


Most commercial and industrial premises have vast roof areas, with equally vast potential to tap into for energy generation.  Many businesses have realised this and turned what would otherwise be ‘wasted’ space into a valuable asset with great potential to make a considerable contribution to their bottom line.

This applies not only to new construction projects but to existing buildings.  The same is true in residential developments – including existing properties as well as new build.  Electricity generated this way helps to guarantee an uninterrupted power supply and gives fixed costs that can be used in forecasts.  

Solar panels reduce costs for your business by generating free, green electricity to be used onsite, lowering your energy demand from the grid in daylight hours and saving you money every year on energy bills. 

Making the change to an energy efficient, eco-friendly solution with Low Carbon Energy needn’t be cost-restrictive.  If you’re unable to purchase the system outright iGen can also offer Power Purchase Agreements (PPA’s) which will allow businesses to secure a portion of their annual electricity consumption from solar power, at absolutely no upfront cost.

Power Purchase Agreements

iGen partner with some of the best energy efficiency asset investors and can offer you a completely free, fully maintained solar PV system through an attractive PPA for 20 to 40 years. During this term, electricity generated by the PV system is purchased from the investor at a cheaper rate than your existing energy supplier – with superior price inflation than the energy market – giving you long term control over your P&L Costs and saving you money.

What is a power purchase agreement?

A Solar PPA is an agreement under which a PPA investor (developer) arranges for the design, financing and installation of a solar PV system at a commercial site, at no upfront cost to the site operator (usually, but not always, the site owner).

iGen’s role is to provide initial design and manage the installation, as well as on-going maintenance, monitoring and services to the developer, with end-to-end project management using our experienced in-house design and installation team. 

The developer sells the power generated to the site operator at a fixed rate that is below the rate available via the grid. This lower electricity price serves to offset the customer’s purchase of electricity from the grid. 

Solar PPA rates: No upfront costs or ongoing fees

No upfront costs or ongoing service fees apply, meaning that you begin to make savings from day one and continue to benefit for the full term of the PPA, usually for a minimum of 20 years. At the end of the term, it is common practice that the PV system will be gifted to you for a peppercorn fee (£1).

Benefits of a PPA

  • No or low upfront capital costs: The developer manages the upfront costs of sizing, procuring and fully installing the solar PV system. Without any upfront investment, the site owner can benefit from solar energy and start saving money immediately as soon as the system is installed.
  • Reduced energy costs, with stable inflation rates: Solar PPAs provide a fixed, predictable cost of electricity for the duration of the agreement. The fixed cost per kWh paid for solar energy typically inflates either at a known fixed rate or at the rate of RPI.  Both inflation rates are below forecasted electricity price inflation.
  • Limited risk: The developer is responsible for all installation, system performance, maintenance and operating risk.
  • Zero cost 'green':  positive CSR benefit, Improved sustainability and contribution to renewable energy goals.

Our experienced team will conduct an analysis of your roof, type, pitch, size and orientation and will assess your current electricity infrastructure, usage and bills to ensure you are a suitable candidate for a Power Purchase Agreement.

The asset investor will also be looking to minimise risk on their part, which will require you to provide evidence of long-term stability (i.e. financial accounts) and, if you don’t own the building, any rental agreements that give the investor assurance that you won’t be vacating the property during the term of the PPA.


It’s an alarming reality that the national grid is struggling to generate significant electricity supply to meet the growing demands of the UK.  Having solar and battery storage at your business will not only save you money but reduce your reliance on the grid itself who are currently taking measures to prevent blackouts in the future.

Secure your future energy supply - Pre-purchase energy at a fixed unit price, forecast your long-term energy costs and protect your business against future increases in utility prices.

Protect your business from power shortages - Generate and store your own energy, reduce reliance on the National Grid and protect your business from potential rationing and brownouts.
