We fund, build and operate solar on your factory roof. You buy the power at a contracted rate below your EVN tariff, with nothing to invest upfront.
Every month you delay, your competitors lock in lower energy costs. Here's what switches the moment you sign.
We fund the full investment into the solar rooftop system. You invest nothing. No CapEx approval needed. No balance sheet impact. Just lower electricity bills starting month one.
Your PPA tariff sits below the EVN rate you pay today, with the price path fixed for the term. You pay only for the kWh the system actually delivers, so underperformance costs us before it costs you.
Secure verified Renewable Energy Certificates for every MWh generated. Meet RE100 and CDP supply chain requirements — the solar system provides the foundation for certification.

*Estimate over a 20-year PPA term. Assumes today's EVN tariff rising 3% a year and an illustrative discount; your actual rate is set in your proposal.
It means exactly that. Blueberry Energy funds 100% of the system — design, equipment, installation, and commissioning. You pay nothing upfront. No hidden fees. The PPA or leasing fees are consumption linked, and the cost per kWh is lower than your current EVN tariff.
Your PPA tariff is set below the EVN rate you pay today, so every solar kWh you consume costs you less than the grid equivalent. How much that adds up to depends on your factory's location, which determines solar irradiation and so how much the system produces; on your tariff band; on how much of your load falls in daylight hours; on how much usable roof you have; and on your project's specific requirements. That is why we model it on your actual consumption data rather than quote an average. The saving compounds over the contract as grid tariffs rise while your solar rate stays on its agreed path.
Blueberry Energy owns, operates, and maintains the system for the contract duration. You own the savings. At contract end, the system is transferred to you at no charge, so you can keep using the power it generates. If you would rather not keep it, we remove it at no cost.
Months rather than years, from signed PPA to first electrons. Permitting, equipment delivery, and installation and commissioning run largely in sequence, and a straightforward rooftop moves considerably faster than one needing structural work or a complex landlord consent — so we give you a dated schedule with the PPA proposal rather than a generic number here. Production is not disrupted during installation.
No. We conduct a full structural assessment before every installation. Our mounting systems are non-penetrating for flat roofs.
If you have 1,000+ m² of usable rooftop space and a monthly electricity bill above VND 50 million, we will be pleased to propose a solution. We serve factories, warehouses, logistics centers, commercial buildings, and industrial parks across Vietnam. Use our calculator to check your potential.
