Financing Routes
From full purchase with maximum returns, through bank financing at preferred rates, to BOT and roof-lease models with zero upfront investment. Each track is a separate agreement with its own risk, return and ownership profile — the right choice depends on system type and available capital.
Three Models — Each Fits a Different Situation
The difference between the tracks is purely financial. In each one, we build the same system, handle all the bureaucracy and support you for the entire contract duration.
Full Purchase
Full payment from your own capital. Full system ownership from day one, with all annual revenue flowing directly to you.
Bank Financing
A dedicated loan for the system — full or partial — from a partner bank, at a rate of 6%–7%. We assist throughout the bank process. You own the system from day one.
Zero Upfront Investment
We build and operate the system at our expense. Pick between two variants: BOT (Build-Operate-Transfer) that flips ownership to you at the end, or a Roof Lease with a fixed monthly payment from day one. These models apply only to commercial systems and Helka A.
Zero Upfront — Two Variants
Same system, same bureaucratic handling — but a fundamentally different income structure. BOT fits those who don't need immediate cash flow and want a revenue asset in 10 years. A roof lease fits those who want fixed, immediate income from day one. Both models are available for commercial systems and Helka A only.
BOT · Build-Operate-Transfer
System transfers to you after 10 years
BOT is a standard infrastructure model (Build–Operate–Transfer): we build the system at our expense, operate it, and retain all revenue for the first 10 years. After 10 years the system transfers to your full ownership for the rest of the contract — and you collect all revenue it produces from that point until end of life.
Roof Lease · Site-Lease Model
Fixed monthly payment from day one
In the site-lease model (also called 'roof lease') we lease your roof or land for the full contract period. We build the system, operate it and collect all revenue from selling power to the grid. In exchange you receive a fixed monthly rent from the first month — unrelated to actual production or the tariff paid to us.
Which Track Fits You?
The four tracks side by side — across the criteria that matter most.
* The table describes general characteristics of each track. Specific amounts depend on system size, location, customer type (private / commercial / Helka A) and the tariff at commissioning. We build a project-specific financial model before signing.
