AIKO vs KB Solar - solar panel manufacturer comparison

KB Solar is a small US-based manufacturer and installer founded in 2022 by brothers Ivan and Alex Karastanov in Spartanburg, South Carolina, where "KB" reflects the family name behind the business. It operates at a regional scale, assembling panels locally and targeting primarily the South Carolina market. No Tier 1 or BloombergNEF bankability designation has been documented for the company, and its annual production volume is not publicly reported - consistent with its position as a niche domestic assembler rather than a utility-scale supplier. AIKO, by contrast, is a Chinese manufacturer headquartered in Guangzhou that has grown rapidly into a globally recognized player, achieving BloombergNEF Tier 1 status as of Q3 2024 and reporting cell and module capacity in the tens of gigawatts per year, with roughly 12 GWp of modules shipped in the first half of 2025 alone. On institutional footprint and financial bankability, AIKO is in a categorically different tier.

KB Solar's current catalog centers on PERC-based panels in the 375 W-450 W range, with half-cell and 12BB configurations offered in both monofacial and bifacial variants, accompanied by a 30-year performance warranty and a 12-year product guarantee. The product line is well suited to residential and small commercial rooftop projects in the US Southeast, where local assembly and responsive customer service are competitive advantages. AIKO has built its reputation around its proprietary ABC (All Back Contact) cell technology, which places electrical contacts entirely on the rear of the cell to eliminate front-side shading losses. The resulting Neostar modules have reached mass-produced efficiencies above 24%, among the highest recorded for commercial panels, and the brand has expanded across residential, commercial, and utility segments globally, winning the 2025 SolarQuotes Installers' Choice Award in Australia.

For most buyers outside the US Southeast, AIKO is the stronger default in 2025 - it carries verified bankability, industry-leading efficiency, and a global service network. KB Solar makes sense for buyers who specifically value US-assembled product, want a local relationship for a smaller residential project in South Carolina, or are operating under a domestic-content procurement requirement, but it cannot yet match AIKO on third-party bankability, technology leadership, or supply scale.
