Robert Frowein initiated and founded Calfula together with two partners in 2012. At this time PV was widely unknown in Chile – even though the country has spots with the highest solar irradiation worldwide, a widely deregulated economy and among the highest prices for electricity in South-America (in 2012). The potential for a massive deployment of PV was foreseeable. 

Calfula developped a sustainable business model and built up a team in Santiago together with Eren, M+W and Kraftwerk. Nevertheless Calfula has up to today not been able to realise a project - because limited transmission capacities for electricity caused market prices for electricity to decrease to levels where investments in PV plants could not be recovered.

Today Calfula has a representative in Santiago de Chile.
