Slim solar panels mean more power from restricted roof space
|20 year Return||£22,000|
|Payback||7 years (15% return)|
|Cost||£7,000 - £10,000|
|Bill Saving||£400 p.a.|
|Carbon Offset||2,000 Kg p.a.|
Return is calculated using combined bill savings and subsidy earnings. Bill savings are calculated using estimated energy usage and either the electricity price at the time of installation (10 October, 2013) or, for our heating products, the existing fuel type available to the property.
Mr & Mrs Martin own a detached house in Crowbrough, East Sussex. They were keen to protect themselves from rising energy bills and take advantage of the Feed-in-Tarrif over the next 20 years. They could see that the annual return from solar PV was a much better investment than their savings or ISA plans could offer. They were also keen to reduce their carbon emissions by using renewable energy.
After extensive design work and discussion, EnergyMyWay recommended and installed a 4kW array using Black ZNShine panels with a Samil inverter.
The ZNShine panels were selected because of their slightly smaller size (just 0.8m wide), which meant roof space could be used more effectively to achieve a peak output power of 4kW, instead of 3.5 kW from standard sized panels. The ZNShine panels have an excellent 25 year performance warranty (backed by the large insurance company PowerGuard) and the panels are imported directly into Kent from Asia by a locally based importer, helping reduce the carbon footprint of the panels.
