Quark Solar Pvt Ltd (formerly known as PAE renewables) began in 2010 to undertake EPC of smaller-sized battery-based solar rooftops at a time when solar was not commercially viable. Thereafter since 2015 it has transitioned into larger commercially viable industrial and commercial rooftops, across India, with experience also on MW scale, open-access, ground-mount projects. Quark Solar offers solar projects under CAPEX, OPEX and EMI models with its own investors; however, it also works with external investors when an opportunity arises.
