Sunroof Top Solutions - CAPEX & OPEX

CAPEX MODEL: In this model, the entire investment comes from the power consumer, consumer generally hire a solar EPC company who provide turnkey installation of entire solar power system and hand over assets to consumers. EPC also do annual operation and maintained (O&M) of plant on mutually agreed cost per annum.

OPEX MODEL: In the OPEX model, an investor or project developer (sometimes called Renewable Energy Service Company –RESCO) invests the CAPEX and consumer pays for the energy consumed/supplied by the solar power project delicately developed for a particular consumer. Both consumer and developer sign a long-term power purchase agreement (PPA) for an agreed tenure & tariff.

CAPEX Vs OPEX

Sun Rooftop empowers consumers with two distinct benefits – saving on electricity costs and contributing to the green environment. The two most popular types are OPEX and CAPEX when it comes to investing options in solar roof systems.

We explained in detail which of these models were involved and why one should make investment in the following plans.

OWNERSHIP
