## About

Sunna Design SA was founded in 2011 by Benjamin Fremaux and Cédric Palombo in Martillac, near Bordeaux. The company emerged from a need for reliable, low-maintenance solar lighting in areas without grid access, initially targeting African markets where power outages are frequent. Today it operates as an industrial manufacturer and systems integrator, producing standalone solar streetlights, garden lights, and connected urban furniture. The firm's core product is its patented 'iSSL' (intelligent Solar Street Lighting) line, which integrates high-efficiency monocrystalline panels, lithium iron phosphate batteries, and adaptive LED drivers into a single pole-top unit. These systems can operate autonomously for up to five consecutive overcast days, using a proprietary charge controller. Sunna Design targets both off-grid and grid-tied municipal projects, with confirmed deployments in Côte d'Ivoire, Senegal, Morocco, and France (per company marketing materials). The company also sells into humanitarian and disaster-relief channels through partners like the UN and NGOs. Sunna Design has not publicly disclosed its revenue, installed-base numbers beyond the 120,000-unit claim, or any external capital raises. It operates as a private limited company (SA under French law) with a reported ~50 employees as of 2024. The firm is vertically integrated: it designs, assembles, and tests all products at its Martillac facility, with a stated R&D focus on battery longevity and IoT connectivity. Structurally, Sunna Design is a manufacturer, not a financial entity — it does not deploy capital as a family office or asset manager. Its significance in the allocator context lies in its public-sector customer base: municipalities and governments buying long-lived infrastructure. The firm's ownership and governance remain opaque, with no identified family-office or sovereign-wealth link.
