In Spain in 2007, the Government asked people to invest in solar panels guaranteeing a price that was outrageously high for a long time. Of course then it changed the price and 60.000 families were bankrrupted.

Solar panel were ultra expensive and could not compete with other types of energy.

Of course lots of the people in Government became rich as a result of the operation.

Today we are having problems with solar panels network instability. Yesterday there was a 3 hour blackout in big parts of Spain because solar unbalance.

So it is not that easy.
