Your question about the grid and the roof "talking" is exactly what was described in the article about "curtailment". The problems with curtailment are: 1) The management of roof solar output is currently in the hands of solar roof owners, not grid operators, so the grid operators cannot easily "reject" the produced electricity. 2) Solar installations are often financed with expectations of savings and/or revenue, so if the grid operators curtail the solar generation, do the solar roof owners have a right to be compensated for their lost revenue? How is this compensation managed fairly across all solar roof owners?
