Power Purchase Agreement 2018-05-22T11:50:22+00:00

Zestec enables clients to achieve long term financial savings by generating their own clean, green electricity under a fully-funded, subsidy-free, solar photovoltaic (PV) Power Purchase Agreement (PPA) model.

Clients not only benefit from reducing their carbon emissions, but are protected from long term energy price increases as the PPA is locked into retail price inflation.

How it works

You agree to lease the airspace above your roof* for 25 years and enter into a Power Purchase Agreement (PPA)

We install our solar PV system on your roof, free of charge

You pay a low rate per unit of solar electricity you consume

We monitor, maintain and insure the system for 25 years, at no cost to you

Please click ‘monitor’ for remote monitoring demo site
*PPA’s are also available for ground mounted and even floating solar PV systems

How you benefit

Free solar PV system

The system is fully funded by us.

Immediate savings on electricity bills

Solar electricity you consume is purchased at a rate cheaper than is available from your current energy provider.

Zero cost ‘green’ credentials

A zero capital route to improving your company’s environmental responsibility, enhancing relations with green thinking customers, suppliers and staff.

No maintenance or insurance costs

We proactively manage the system under a long-term operation and maintenance contract, including provision of insurance cover, all at no cost to you.

Long term protection against energy markets

The unit price you pay for electricity generated by the solar PV system will only rise in line with RPI, allowing you to budget more effectively.

Fully transferable

The PPA can be transferred to new occupants of the property should you move to new premises.

Typical savings you can expect to receive

Zestec fully funds the entire installation of a solar PV system and you benefit by consuming the discounted solar electricity which is generated.

After 25 years, ownership of the system transfers to you and you enjoy free solar electricity for the remaining life of the system (c. 10 years).
