Solar Energy Systems


The Solar energy market can appear to be very confusing on first glance and extremely complicated, but in truth for the user it’s not really that complex. It is ultimately all about the benefits it can deliver to both the energy consumer and the environment.

In simple terms a Solar energy system is about harnessing the sun's immense natural power source to either convert sunlight to electricity using silicon cells or its thermal energy for direct water heating both with the objective of saving money and of course the environment. Renewable energy comes from natural sources, including sunlight, rain, wind and the tides.

John Warner Electrical Contractors provide a Solar PV Home Energiser Solution using PhotoVoltaic panels to generate your own electricity and connect into the grid because it believes it is the best long term offering and enables users to gain both maximum energy and cost benefits.

The Government have committed to decreasing our dependence on fossil and nuclear fuels and have legislated a Feed In Tariff (FIT) sometimes called Energy Cash Backs effective from April 2010. This FIT requires energy companies to pay a premium price to you, the energy generator for all the energy produced by your solar system, whether it is consumed at your property or exported back to the grid, provided your system is installed by an MCS accredited installer, as we are.

•  A typical 3.8 kW Retrofit system would return an income of up to £650 per anum for the  generation in feed in tariff alone. South facing roofs optimise the systems
•  The starting rate will last for 20 years, long after the system has paid for itself
•  The rates are set to rise with inflation annually
•  Feed in tariff income is tax free
•  Energy consumed is offset from your bill with any exported electricity being valued at 4p per kW
•  PV Installations benefit from a reduced VAT rate of 5%


If you are a householder in Penzance and the surrounding area who is looking to find out more about Grid Connected PV Systems and how to get them installed on your property you are in the right place.

  • Receive a guaranteed price per KWh for the next 20 years
  • Reduce your electricity bills
  • No moving parts – silent in operation
  • Normally no planning permission required
  • Zero CO2  emissions
  • Solar PV is the most proven renewable source
  • Increase the overall value of your home

The first thing you need to be aware of is The Micro generation Certification Scheme (MCS). This is a Department of Energy supported scheme that certifies equipment and installers for the supply and installation micro generation systems.

Next you will need to know if your house or work place is suitable for a solar micro generation solution.

If you are looking to benefit from the feed in tariff then you must use MCS approved equipment and installers which John Warner Electrical have achieved through the NIC EIC.  If you would like more information on this service please contact us.

Our aim is to provide honest and independent advice on the most appropriate solution for each individual project because every customer has different energy needs. Now is the time for us all to be more aware of where our energy comes from and how precious it is.

One way to do this is to harness the energy from natural elements, such as the sun and this is where we can help you make a positive change to your future. With Government Feed-in Tariffs available, it is time that we all invested in our futures.

We only install MCS accredited solar PV panels which will enable our customers to claim the UK Government Feed-in Tariff (FITs).

So, if you are interested in reducing your carbon footprint and saving money, contact us and we will give you all the help and advice you need.
