Just thought I'd mention that, as existing generators we will only get 9p per unit until 2027!
This figure is set to remain at that level regardless of future increases in price of electricity.
We have encouraged others to also generate their electricity and regularly have people round to have a look at our system. Since the announcement of FITS they all ask when they will start making a profit and how long is payback time etc.
We are unlikely to ever make a profit (in our lifetime that is as we've been around a long time already!).
The fact that our Government should have been encouraging micro-generation several years ago as they have in other countries is obviously irrelevant. A bit peeving for us but not exactly unexpected.
Our system continues to work fine. We generate enough for ourselves and for another household with their renewable electricity via the National Grid.
