Solar photovoltaic panels

Considering Solar PV for your home?

Installing solar photovoltaic (PV) panels and generating your own renewable energy for use in your home is a great way to reduce your energy demand from the grid and therefore your energy bills.

This green energy also doesn’t release any carbon dioxide or greenhouse gas emissions during generation or transmission, reducing your carbon footprint and your impact on the environment. 

The installed cost of solar panels has fallen considerably over the last decade as the market has developed and the technology has proven itself in terms of generation output.  Financial incentives are also still available in the form of the Smart Export Guarantee (SEG).

The Energy Saving Trust provide lots of information on solar investment for your home and offer a solar energy calculator to help model the financial and environmental benefits you could expect to see from a system installed on your home.

The Council invested in solar PV for some of our Council properties in 2015/16.  The performance of a 2, 3 and 4KW system has been charted below to illustrate real-time performance of systems locally in West Lancashire.  Monitoring of our PV systems over the years has provided confidence in their performance and outputs, with most systems achieving or exceeding estimated generation levels.

The graphs below provide a closer look at the performance of a 3KW system located on a Council property in Skelmersdale.  As illustrated, the system has been preforming well, meeting or slightly exceeding estimated generation levels year on year since installation.

The system has been generating an average of 2,500 KWh a year.  Using an average electricity price of 14p/KWh, this system has been providing £350 of renewable electricity for use in the property a year.  Using this energy rather than that from the grid will provide a saving on your energy bills and a provide a return on your investment.

This system is also saving over half a tonnes of greenhouse gas emissions a year, reducing the carbon footprint of the property and contributing to our carbon neutrality aspirations.
