@grahamf They are not interested in small installations and they take advantage of the fact that there can be enough generation to still make it attractive.

There is another factor which I think smells somewhat.

My contract is with EDP, but when Solar PV came along they split off the entire distribution business to a new company, E-REDES and all questions of import/ export have to go through them even though there is no contractual connection.

I have a fight with them currently after a very unlikely bill in February and with a meter check tomorrow.

Same here, you buy (or sell) electricity from/to one company (an electricity retailer), but its another company (the distribution network operator) that has to agree to solar/battery connection.  However the regs oblige the DNO to agree to connections up to a certain amperage and oblige the larger retailers to pay for exported electricity (albeit at a lot less than 12p/kWh). 

This seems to be a case where the UK got it right.  Better not let certain sectors of the UK media know, it will spoil their fun.
