I've had panels installed which I have paid for but I have forgotten to apply. Can I still register them for Feed-in Tariff payments?

If you have had additional capacity added to your existing system and this was prior to the 15th January 2016, we needed to have received your application in respect of this before the 1st April 2016. If you did not apply to us before then, the additional capacity you have installed will not be eligible to receive FIT payments.
