CHOOSE YOUR MODEL

PPA OR EPC

Two paths to solar, one clean energy goal. Whether you'd rather own your system outright or enjoy cheaper power with zero upfront cost, GreenAura makes both routes simple.

UNDERSTANDING THE MODELS

Both EPC and PPA get you clean, reliable solar power — the difference lies in who owns the system, who pays upfront, and who takes on the long-term responsibility. Understanding this difference is the first step to choosing the model that fits your budget and goals.

THE TWO PATHS TO SOLAR

Understanding EPC & PPA

Compare ownership, cost and responsibility before you decide.

01 Own It Yourself

EPC

Engineering, Procurement & Construction

You purchase the solar system outright, and GreenAura handles everything — design, sourcing quality components, installation and commissioning. Once live, the system and all its power belong entirely to you.

  • You pay the full project cost upfront (or via loan)
  • Full ownership of panels, inverter & generated power
  • Eligible for government subsidies & tax benefits
  • Highest long-term savings once payback is achieved
  • Asset adds value to your property
Best for: Homeowners & businesses with capital available who want maximum long-term returns and full control over their system.
02 Pay As You Save

PPA

Power Purchase Agreement

GreenAura designs, installs, owns and maintains the solar system on your rooftop at zero upfront cost to you. You simply buy the power it generates, at a rate lower than your regular electricity tariff.

  • Zero upfront investment or capital cost
  • GreenAura owns, operates & maintains the system
  • Pay only for the power you actually consume
  • Predictable savings from day one, no maintenance worry
  • Option to own the system at end of PPA term
Best for: Businesses & institutions that want immediate savings without tying up capital or managing upkeep.

Choose EPC If You...

  • Have the budget or financing ready to invest upfront
  • Want to claim depreciation, subsidies or tax benefits
  • Plan to stay in the property or business for the long haul
  • Want complete control over your energy asset

Choose PPA If You...

  • Want to go solar with zero capital expenditure
  • Prefer to avoid maintenance and operational hassle
