Businesses looking for cheap energy could benefit from applying for the upgraded Feed-in Tariffs (FiTs) scheme.
Solar panels will be eligible to earn their owners 21p/kWh from April 1st, with the eligibility date commencing on March 3rd.
However, the building the generator is being added to must have an Energy Performance Rating of at least D.
Furthermore, micro-combined heat and power (micro-CHP) installations will receive larger sums of money in order to encourage the development and use of this technology.
FiTs provide a subsidy for consumers and companies investing in low-carbon or small-scale renewable technologies, including anaerobic digestion plants, wind and hydro power generators, micro-CHP and solar panels.
Climate change minister Greg Barker said: "Our new plans will see almost two-and-a-half times more installations than originally projected by 2015 which is good news for the sustainable growth of the industry."
He had previously claimed during the Solar Power UK conference that at least 100,000 households are benefiting from FiTs.
