GENERATE CHEAPER, GREEN ELECTRICITY USING SUNLIGHT

Although the British weather may be unpredictable, there is still enough radiation from the sun to generate electricity using solar panel systems – otherwise known as Solar Photovoltaics (PV). The cells within the panels do not require direct sunlight and can in fact generate electricity even on a cloudy day. Hr Hislop are Calne electricians who can specify and install domestic solar Phiotovoltaics throughout the local area.

HOW DOES SOLAR PV WORK

solar panels installed on roofPV cells are made from layers of semi-conducting material – usually silicon. When light shines on the cell it creates an electric field across all of the layers. The stronger the sunshine, the more electricity is produced. Groups of cells are mounted together in panels or modules that can be fitted to your roof or even mounted on the ground.

The power of a PV cell is measured in kilowatts peak (kWp). That is the rate that electricity is generated at peak performance – in full direct sunlight during the summer. PV cells come in a variety of shapes and sizes, although the most popular are the panels mounted on to an existing roof.

A standard 4kWp system can generate around 3,800kw hours of electricity a year in the south of England – that’s enough to power a typical family home.

If your system is eligible for the Feed-in Tariff scheme you could generate savings and receive payments of £610 – £740 per year.

SOLAR MAINTENANCE

Solar PV needs very little maintenance, the panels just need to be debris-free from any nearby trees. Most UK panels are at an angle which allows for the benefit of rain water to clean them whenever it rains – a nice eco bonus!

The panels should last 25 years or more, but the inverter is likely to need replacing during this time period. Currently this cost is approximately £800.

FREE QUOTATION

If you want to see what could be done at your property, and see what sort of long-term savings you could make on your bills then please get in touch with our team of electricians. We will come out and do a quick survey of your roof for suitability and discuss an appropriate system size for the property. From there we will put together a quote which will give you all the information you need to make an informed decision – to include full installation costs, and a performance estimate on what is a realistic expectation of savings for your property.

BENEFITS OF SOLAR PV

Cut your electricity bills

Get paid for the electricity you generate

The UK governments Feed-in Tariff scheme pays you for the electricity you generate, even if you use it!

Sell electricity back to the grid

If your system produces more electricity than you need, you can sell the surplus back to the grid!

Cut your carbon footprint

Solar electricity is a green, renewable energy that doesn’t release carbon dioxide – or any other pollutants!

HELPFUL TIPS FOR SAVING ENERGY AROUND YOUR HOME

Light bulbs

There are two main types of energy efficient bulbs readily available – Compact Fluorescent Lamps (CFLs) and Light Emitting Diodes (LEDs).

CFLs are a cost-effective option for most general lighting requirements. They can save you approximately £3 a year which is £50 for the life of the bulb.

LEDs are particularly good for replacing spotlights and dimmable lights, although they are more expensive to purchase in the first instance. They are more efficient than CFLs and will save you more money in the long term. If all halogen downlights were replaced with LEDs in a property, you could expect to save around £30 a year on your electricity bills.

Other ways to save money on electricity

You can save money and energy by being conscious of how you are using energy and implementing some basic control mechanisms.

  • Always turn lights out when leaving a room
  • Be aware of how many lights you have on, and whether they all need to be in use
  • Arrange light switches at convenient locations around your property ie: top and bottom of stairs, each end of the hallway and by each door in a room
  • Use a sensor and timer on outside lights so they are only in use when they need to be
  • Use appropriate lighting for your activity, for example: a low background light for watching television, and a bright concentrated light for reading. Having a variety of lights in a room would make this easier.
