Solar
photovoltaic (PV) panels use sunlight into electricity, which is then
to power household appliances and lighting can be used to generate.
PV systems are installed on the roof of a building or a wall compared to 90 degrees south, as long as there are no obstacles to sunlight such as trees or other buildings. If the PV panels are in the shade most of the day, they are still produced, but less amount of electricity.
It has significant reduction in the cost of installation of a domestic solar system in recent years in the UK. In May 2012, the Department of Energy and Climate Change in the UK led a survey to assess the cost of installing a PV system average domestic 3kWp the assessment. According to their findings installation costs vary between installers, suppliers and brands and could be in the region of £ 7,700.
In April 2010, the UK government introduced the feed-in tariff scheme to encourage households adopt solar power and install them in their homes. Who generates its own electricity with photovoltaic panels, feed-in tariffs scheme provides opportunity for energy costs and earn tax-free income for 20 years to save.
The Feed-in Tariff scheme is to use a great perspective for all. The benefits outweighed the need for pre-installation costs. Not only that, wearing everyone who is involved to reduce carbon dioxide emissions and less dependence on non-renewable energy sources.
A large amount of the UK residents have already wins the trend in energy efficiency and self-confidence connected in meeting energy needs. Imagine producing your own clean energy and earn at the same time.
Earnings
A 2.5kWp system costs to install approximately £ 6,000. The system is £ 547 per year and will return to recover the cost of installation in 10 years. This is a total ROI of 9%.
Generation Tariff: £ 347 per year
Export Tariff: £ 49 per year
Electricity Bill Savings: £ 151 per year
Total income in a year: £ 547
Pros
• Only natural light is needed to produce energy - not sunshine.
• Excess energy generated will be sold back to an electricity company. 40% reduction in the average household electricity bills.
• The feed provides additional income
Cons
• a large roof area is required to install the plates so as to generate considerable amounts of energy.
• High initial investment - usually £ 7700 for a 3kWp system.
• Efficiency depends on the number of hours of sunlight and air in the locality.
• Un-shaded southern exposure is must for the installation.
• roof of the house where the solar panels are to be installed must be strong enough to withstand the weight of the plates.
With sky rocketing energy prices, there has never been a better time to spend on solar energy. Government support it through financial incentives in the form of feed-in tariffs. Once installed, the solar panels will provide energy for free. The sun - No one can help you pay for the use of power by the dominant energy source....
