Ireland's BNRG Renewables has commissioned 30MW of PV plants in the UK.
The projects - 20MW in Kent, southeast England, and 10MW on the Isle of Wight, off the southern coast - have a total estimated value of €52m ($70.8m).
The Kent project is one of the largest solar parks in Britain, while the 10MW Hill Farm sits on a plateau on one of the highest points of the Isle of Wight, minimising visual impact.
For both projects the development phase was executed and funded by BNRG.
The construction funding was provided by British investment specialist Octopus Investments. The projects were jointly built by BNRG and Lightsource Renewable Energy, with Groupotec, a Spanish construction company, as lead contractor.
"Ireland, like the UK, has huge potential for solar energy. It is unfortunate that we have yet to include solar in renewable-energy policy, unlike the UK, which has seen significant benefit from the roll-out of large-scale solar," says BNRG founder David Maguire.
The company recently received planning permissions for the first utility-scale solar park in Northern Ireland, at Bishops Court.
It is also about to sign construction contracts for a €24m, 15MW array near Chichester, southeast England, valued at €24m.
