What is a solar Power Purchase Agreement (PPA)?

A solar PPA is an agreement where Enersol installs, owns, and maintains the solar system at your premises at zero upfront cost. You pay only for electricity generated at a rate 15–25% lower than the grid tariff. This is also called the OPEX or third-party solar model.

Is there any upfront investment required for a solar PPA?

No. Under Enersol's third-party PPA model you pay zero upfront. Enersol funds the entire project — design, procurement, installation, and commissioning. You start saving from day one by paying a per-unit rate lower than your current electricity bill.

How long is a typical solar PPA contract with Enersol?

Solar PPA contracts are typically structured for 15–25 years with a fixed or mildly escalating per-unit tariff agreed at the outset, giving long-term price certainty against rising grid tariffs. At contract end the system is transferred to you or decommissioned.

Who maintains the solar system under a third-party PPA?

Enersol retains full ownership and handles all maintenance, cleaning, inverter servicing, and performance monitoring throughout the PPA term. You have zero operational responsibility — if the system underperforms, Enersol bears the financial risk.

Net Metering: Sell Excess Power to the Grid

Net metering is a government-approved system that allows homeowners with solar panels for home to export excess electricity to the grid and earn credits on their electricity bills. When your residential solar system generates more power than you use, the extra electricity is sent to the grid, helping you maximize savings and make the most of your solar electricity for home.

Benefits of Net Metering

Sell excess power at retail tariff rates
Credits roll over monthly (annual settlement)
Bidirectional meter tracks import/export
Reduces electricity bills to near zero
No battery storage needed
