When is a subsidy not a subsidy.
I did a bit of fact checking on government subsidy of solar and found only two countries, Spain and Italy, make direct subsidies.
The other countries listed, make tax breaks, VAT exemptions and FIT (feed in tariff) rules none of which, to my mind. costs the taxpayer anything.
