Solar isn’t just panels on a roof anymore. It spans materials science, storage, and access models built for markets that need it most. Looking at real companies instead of category labels, three approaches keep showing up.

1 Push solar hardware past standard panels

The first pattern is materials and manufacturing innovation — projects rethinking how solar cells and glass are made and where they can go. Examples range from sand-based panel production to solar glass built for greenhouses.

Manufacturing

Maana Electric

TerraBox solution enables on-site production of solar panels from sand, boosting efficiency while supporting local economies.

Agrivoltaics

Brite Solar

Solar glass technology for greenhouses and open-field cultivation, combining energy generation with water savings for farming.

Solar + Storage

RayGen

Combines high-efficiency solar generation with long-duration storage to deliver reliable, dispatchable renewable power.

2 Get more usable energy out of the sun you already capture

A second group focuses on optimization after generation — storage, heat capture, and smart controls. These squeeze more value out of an existing solar setup rather than adding more panels.

Energy Storage

Wanit

Combines hot water and electricity storage in a compact system that adapts to existing solar setups, maximizing efficiency and savings.

Solar Thermal

Sunoptimo

Opticube system delivers efficient solar heat, reducing reliance on fossil fuels with affordable, easy-to-install solar thermal energy.

Smart Controls

Astrel

IoT controls for solar photovoltaic energy and home automation, optimizing production and self-consumption under its 4-noks brand.

3 Bring solar access to underserved markets

The remaining projects focus on access rather than technology — bringing solar power and financing models to regions and businesses. Many would otherwise be locked out of clean energy.

Africa

DAEL SOLAR

Provides solar energy solutions across West and Central Africa, focused on energy independence and sustainable development.

Financing Model

UrbanVolt

Solar as a Service and Light as a Service let businesses adopt clean energy with no upfront cost. This cuts carbon footprints.
