14
Country: USA | Funding: $38.2M
Next Energy Technologies is a manufacturer of organic photovoltaic coatings.
15
Country: Canada | Funding: $33.8M
Solantro’s chipsets and platforms turn solar panels into integrated power generators and allow for the management and storage of renewable energy. The chipsets are designed and built specifically to measure, process and drive complex power architectures from distributed energy resources
16
Country: USA | Funding: $31M
Merlin develops novel solar panels that are significantly lighter than a typical glass panels and their flexible nature changes how and where they can be installed. The panels come with an adhesive on the pack, so they can be attached to surfaces just like a child’s sticker.
17
Country: USA | Funding: $28.2M
Toledo Solar produces the finest CdTe Thin Cell Solar panels, which are designed for a variety of uses from homes and small businesses to large power-generating facilities.
18
Country: Switzerland | Funding: $24.8M
Insolight is an energy company that develops and manufactures solar panels. The technology, called planar optical micro-tracking, allows to concentrate sunlight on tiny solar cells, without any tilt. This makes the use of high efficiency space-grade solar cells affordable, whereas normally there are too expensive to be spread on the full sunlit area.

Country: USA | Funding: $22.7M
SunDensity provides photonic solar conversion products and services.
20
Country: USA | Funding: $19.4M
Leading Edge Equipment Technologies is a developer of kerfless, single crystal silicon wafers intended to be used in solar panels.
