Britain's first solar-powered power plant without government subsidies has been opened by climate change minister Claire Perry, who described it as "an important moment for clean energy ".
The clerhill solar farm near flwick, Bedford County will provide enough power to 2,500 households, as well as battery storage to enable power to be used at any time of the day.
With the advancement of technology, the cost of renewable energy has been falling rapidly, and now it is much cheaper than the new nuclear power.
Hinkley Point C nuclear power plant was built after the government guaranteed a price of £ 92. 50 per megawatt
Electricity for an hour
This means that if the market price falls below this level, the person who pays the bill will pay more to make up for the difference.
Recently, a offshore wind farm received a contract that guaranteed a much lower price. 50.
Fossil fuels have received huge subsidies, such as £ 4.
Government export plans have supported 8bn since 2010, while renewable energy has supported only £ 39 m since 2012.
The solar industry has warned that the government is endangering the solar industry by increasing taxes on solar panels and not giving solar energy fair competition with oil, coal and gas.
But in a statement, MS Perry praised the historic moment of solar power.
"The cost of solar panels and batteries has fallen sharply over the past few years, the first subsidy --
The free development of Clayhill is an important moment for clean energy in Britain . "
"The solar panels have provided enough power.
7 million housing units, of which have been installed since 2010.
"The government is determined to build on this success and our ambitious clean growth strategy will ensure that we continue to lead the world towards a low growth transformationcarbon economy.
Ministers expect more developers to install subsidies, the statement said.
There are free solar farms this year.
Steve Shine, executive chairman of Anesco Clayhill, said this proved that the government did not cut subsidies to a minimum, killing solar energy.
"For the solar industry, clerhill is a landmark development that paves the way for a sustainable future where subsidies are no longer needed or relied on," he said . ".
"It is important that this proves that the government's decision to remove subsidies does not necessarily mean the end of solar energy as a commercially viable technology.
However, Leonie Greene of the Solar Trade Association said that the Clay Hill plant was an exception and once again called for a fair competitive environment with other forms of power generation.
"Solar energy and storage can play an important role in providing consumers with cheap, reliable electricity, so this plan is a very important milestone," she said . ".
"We congratulate Anesco on achieving this in a difficult environment for solar power generation.
It is amazing that British industry continues to innovate with new technologies and we expect many such Pathfinder plans in the coming years.
"The reality, however, is that only a few special projects can be commissioned today.
This exciting pathfinder program has done a lot of work and it has some special features.
"If we are going to achieve national carbon emissions targets and provide cheaper electricity to consumers, then the government must provide a level playing field for solar and new storage technologies.
This means allowing solar to compete again in the UK clean energy auction, which has been shut down for two and a half years.
This also means fair grid handling, opening up the market for many services provided by solar and storage.
"We want the government to take action in the upcoming clean growth plan to create a level playing field for the highly innovative solar industry.
