Somewhat unrelated to amsat-bb, but I will add my two cents.

In the Netherlands the 'old' electric meters are Ferraris meters which just
run backwards when more power is returned.

New meters are 'smart' (electronic) meters which count delivered and
returned power separately. The good thing (compared to the US) is that
Dutch smart meters only use licensed GPRS or CDMA frequencies to
communicate with the electricity company, not powerline communications or
amateur frequencies.

At the moment in the Netherlands the power returned can be crossed away
against power used from the grid and the excess returned will get payment
at feed-in tariff.

In my own situation we do not have a lot of roof space for solar panels,
but a solar panel is high on the wishlist for tent camping trips since this
makes our choice of campings easier while still charging phones / radio
