Aeterna Energy designs, engineers and finances solar power plants end-to-end — so your business and home can cut electricity costs by up to 40%, with zero upfront investment.
From the Latin for “eternal,” Aeterna is what solar really is: sunlight, forever. We are an engineering, procurement and construction (EPC) company and a bankable power purchase agreement (PPA) partner, delivering clean energy across residential, commercial and utility-scale projects.
Aeterna builds, owns and maintains the plant on your premises — you simply buy the power at a fixed tariff below your grid rate, for 25 years.
Under a PPA, Aeterna Energy builds, owns and maintains the plant on your premises. You simply buy the clean power it generates — at a fixed tariff, lower than your grid rate, for 25 years.
No upfront cost, no loans, no EMIs. Your electricity tariff drops the day the plant is commissioned.
Lock in a rate 20–40% below your current grid tariff — insulated from rising electricity prices for 25 years.
Generation shortfalls, maintenance and panel degradation are on us. You only pay for the energy actually produced.
24×7 remote monitoring and scheduled maintenance — all included, so you never lift a finger.
Buy the plant, or buy the power — you choose.
