Notes:

It is assumed 25% of energy is exported and 75% used on site. This is an assumption, and may vary in reality, as each location will have its own load profile..

The equipment and installation must be undertaken by a certified manufacturer/installer
Solar PV Energy yields assume a good location for solar i.e.south facing with minimal obstruction, 
Solar PV Generation base line is 850 kWh/kWp optimal generation, which is adjusted to take into account shading, orientation and angle in the calculation. In parts of southern and western England this may be exceeded
Annual cost saving is based on 10p/kWh electricity prices. These may be variant from actial electrcitiy prices.
Bespoke solutions incorporating solar roof tiles and in roof systems can be provided. The prices here do not provide this.

The tables for heat technologies will be updated when DECC announced the Feed In Tariff rate for kWh payments for each technology/

Ardenham Energy can provide solutions for new and existing build commercial projects.
New build projects are VAT exempt  whereas existing projects would be subject to 17.5% VAT.
