Is solar energy system an alternate source of energy?
Are we using daylight correctly in the UK?
What is PV or solar panel?
Solar panels are also known as photovoltaic PV generating direct current (DC) energy and then converting it to usable alternating current (AC) energy with the help of inverter technology. AC energy then flows through the home’s electrical panel and is distributed accordingly.
- Solar panels absorb the sun’s energy and convert it to DC electricity
- The solar inverter converts DC electricity from your solar modules to AC electricity, which is used by most home appliances
- Electricity flows through your home, powering electronic devices
- Excess electricity produced by solar panels is fed to the electric grid
Solar energy is one of the cleanest forms of energy with least effect on environment.
Solar energy systems/power plants do not produce air pollution, water pollution, or greenhouse gases. Using solar energy can have a positive, indirect effect on the environment when solar energy replaces or reduces the use of other energy sources that have larger effects on the environment.
Solar power represented a very small part of electricity production in United Kingdom until 2011. With the advancement in the technology and the government subsidies has resulted in the increase of PV installation. The installed base has increased rapidly in recent years as a result of reductions in the cost of photovoltaic (PV) panels, and the introduction of a feed-in tariff (FIT) subsidy in April 2010.
In 2012, the government announced that 4 million homes across the UK will be powered by the sun within eight years, representing 22 gigawatt (GW) of installed solar power capacity by 2020. The 72MW Shot wick Solar Farm is the largest in the United Kingdom.
By 2016 the total installed capacity was over 11,000 MW. In the summer half-year from April to September 2016. UK solar PV installed capacity at the end of 2017 was 12.8 GW, representing a 3.4% share of total electricity generation. The all-time peak generation from photovoltaics was 9.34 GW on 14 May 2018.
UK solar panels produced more electricity than did coal power, each is about 5% of demand.
