Rosaz Energies

What Rosaz Energies does

Rosaz Énergies is a French electrical contractor and renewable energy installer headquartered in Saint-Pierre-d'Albigny, Savoie, with a satellite office in Saint-Jean-de-Maurienne opened in 2022. The company traces its origins to Rosaz Électricité, founded in 1971 in Montmélian by Jean-Pierre Rosaz, and was acquired and rebranded in 2006 by current manager Gary Germany, who introduced the photovoltaic activity that now anchors the business. As a privately held SAS with declared share capital of €300,000, Rosaz employs more than 40 trained staff and operates exclusively in the Auvergne Rhône-Alpes region, with project reach extending to Marseille.

The company's offering is organized around three core service lines: (1) solar photovoltaic system design and installation for individual homeowners, local governments, industrial/commercial clients, and isolated sites — including on-grid, off-grid, and hybrid configurations with battery storage; (2) electrical engineering (courants forts and courants faibles) for tertiary and industrial buildings, drawing on more than 40 years of electrical contracting heritage; and (3) electric vehicle charging station installation for individual homes, condominiums, businesses, and public roadways. Technical differentiation rests on an in-house engineering bureau enabling fully bespoke system design, a no-subcontracting delivery model that maintains a single point of contact through commissioning, and a connected-monitor offering on PV and EV charging assets integrated with building management systems (GTB/GTC, KNX). Rosaz holds Qualifelec MGTI Class 4, QualiPV (Elec and Bât), QualiSOL, QualiPAC, RGE, and IRVE certifications.

Rosaz monetizes primarily through one-time project fees: solar installations are quoted on a full-sale, self-consumption with surplus resale, or total resale basis; electrical engineering and EV charging are billed as project-based professional services. All projects are custom-quoted following on-site feasibility studies; pricing is not publicly disclosed. The go-to-market is direct, with no resellers or marketplace listings — enterprise and government clients are reached through field sales and custom engineering proposals, while individual homeowners contact the company via website, phone, and email. Customers rely on Rosaz's RGE and IRVE certifications to unlock subsidies such as MaPrimeRénov', Advenir (up to €2,700 per public charging station), and individual EV-charging tax credits of up to €300. Marketing is largely organic (SEO-optimized website, LinkedIn, Facebook, Instagram, FFB membership) supplemented by word-of-mouth and customer referrals.
