Wholesale working model
We focus on recurring procurement and project-driven demand rather than one-off random orders.
Wholesale solar modules for installers
We supply JA Solar, Jinko Solar, and LONGi modules to installation companies, integrators, and turnkey solar partners across Ukraine.
Why KOLO is easy to work with
A supply model built around the practical needs of installers, integrators, and B2B project teams.
Trusted manufacturers
The assortment is built around JA Solar, Jinko Solar, and LONGi with predictable specifications.
Selection support
We help narrow the right module class, glass format, and wattage band for a specific project.
Clear communication
We reply quickly on availability, timing, and logistics instead of brochure-style promises.
Assortment and module classes
We show brands and core module classes publicly. Pricing and availability stay inside a direct commercial enquiry.
JA Solar
A strong line-up for commercial rooftop and ground-mount projects with current N-type options.
Jinko Solar
A dependable manufacturer for partners who need stable specification across different project types.
LONGi
A solid choice for teams working with larger volumes and expecting a predictable product base.
Technologies partners ask for most often
Monofacial
A standard fit for most commercial rooftops where field geometry and price per watt matter most.
Bifacial
More often used on ground-mount and open-site layouts where rear-side gain can improve output.
N-type TOPCon
A current technology choice for projects where efficiency, degradation, and stronger buyer positioning matter.
Double glass
Relevant where module durability, stiffer construction, or tougher operating conditions carry more weight.
What selection usually comes down to
440–460 W: a common band for commercial rooftops and regular installer demand.
580–720 W: more relevant for ground-mount and larger-format project layouts.
Glass format, bifacial vs monofacial, and frame details depend on site type, structure, and project economics.
