With the drop in the supply price of solar panels, the cost of installations, a LOT more sun (than England) and the much higher electricity prices now means that an economic investment can be made in Solar PV without the need for Feed-in-Tariff or Renewable Energy Obligation support . Of course that is at the industrial scale! – In just one province – Murcia in South East Spain – they plan to install 2.5GW of solar PV – that’s 10 times more than they did in the last two years alone.
