Energy companies stolen profits

There is injustice in the energy companies through windfall profits as a result of the Feed-in Tariff they give people who have solar panels compared with electricity charges. I estimate that given what they pay me for excess power I generate and what they charge per kwh to those like me who use it my house alone resulted in around £800 windfall profits to energy companies. Multiply that by the odd million houses with solar panels then we are talking of billions of pounds stolen from ordinary people. Windfall profits for doing nothing except being miserly to those with solar panels who feed power to the National Grid. Ofgem and the government are aware of this but have done nothing to address the situation.
