About

Solar PV panels directly transfer the light from the sun into DC electricity, and then using an inverter, into AC electricity which can be fed into the national grid. This means your solar panels generate electricity that you can sell back to the national grid through the FiT (Feed-in Tariff) government financial scheme.

You not only generate your own electricity to use for free, but you get paid (tax free and RPI linked) for each kWh of electricity generated as well as exported by your panels - for 20 years!

With our new 2014 pricing you can earn more than a 10% return on your investment!

Where

Your solar array can be installed on your property roof. However this is by no means a restriction, for example they can be placed on the grounds of your property, in a field, on a barn or stable roof. This may be appropriate if your property roof is north facing or too small.

Solar PV with Hot Water Systems

Solar Electricity is a green, renewable energy which doesn't release any harmful pollutants. So why not make full use of it to reduce your fuel and electricity bills, as well as reduce CO2 emissions? During the brighter months of the year, PV systems generate more energy than is consumed by the average household. Typically as much as 50% or more is sent back to the grid, and if you want the electricity back you'll have to pay for it!

So How Do I Save?

We have Systems that are able to monitor power being imported/exported to the grid. These can determine whether or not there is enough excess power to supply to an immersion heater. The control is clever enough to detect changes in the weather and/or increased consumption in the home. If there is not enough extra energy, it will switch off the immersion automatically ensuring your water is only being heated by electricity produced by your PV system.

Costs

The typical size of your average PV system is around 3kWp (unit of power). From an assessment conducted by the Department of Energy and Climate Change the average cost of a solar PV system was deemed to cost around £10,000 (including 5% VAT) based on a 3kWp system as of May 2012. Costs have fallen significantly over the last year and we are able to install such systems for around £6,800 (including 5% VAT). * This figure is merely a guide and is subject to change in system and materials costs; as well as individual property requirements.

Other factors that affect PV installation costs:

  • Larger systems (up to 4kWp) are generally more cost-effective than smaller systems when the return on your investment is considered.
  • Panels that need frames for flat roof or ground-mount installations are typically more expensive than those that fix onto a pitched roof.
  • Most panels are rated around 250Wp each, i.e. 16 panels would create a 4kWp system.

Savings

A 3kWp system can make over 3,300kWh of electricity a year - approximately 3 quarter's of the average householder's electricity requirements. As well as a saving of over a tonne of carbon dioxide each year.

With the Feed-in-Tariff scheme you could generate savings and income of around £800 per year. You will get paid for both used and generated electricity. What you don't use will be exported and sold to the grid. (This is based on a 3kWp solar PV system with the current generation tariff of 14.38p/kWh).

Maintenance

Solar PV systems require little or no maintenance. It would be worth making sure panels are kept relatively clean and make sure trees don't become overgrown and begin to cast shadows. If the panels are fitted at around a 15 degree angle or more they have the benefit of being cleaned naturally by rainfall. Dirt is more likely to cause a problem if you have ground mounted panels.
