RESCO / Opex Solar Model
Go solar with zero upfront investment. Under our RESCO model, HeliosNatural owns, operates and maintains the system — you simply pay for the power you use.
Solar Without the Capital Outlay
Under the Renewable Energy Service Company (RESCO) or Opex model, HeliosNatural finances, installs, owns and maintains the solar system on your premises at no upfront cost to you. You sign a long-term Power Purchase Agreement (PPA) and pay only for the electricity actually generated, typically at a rate below your existing grid tariff.
This model shifts all performance, maintenance and technology risk to HeliosNatural, letting homeowners, housing societies and businesses access solar savings immediately without capital expenditure, loans or ownership responsibilities.
How the RESCO Model Works
