Description
SIREOS is a fast-growing player specialising in the turnkey construction of large-scale solar PV and energy storage projects in Europe. Since its creation, Sireos has delivered or secured more than 1,000 MWp of projects in less than 4 years. The Group has set itself a clear ambition: to make SIREOS a European reference in solar and storage. It rests on four priorities: our international development, Already established in France and Italy, the company is now accelerating its European development. The Group Strategy & Development Department leads the start-up phase of each new country, from the identification of the market opportunity through to the first contracts and the preparation of the operational launch. several high-potential geographies These markets are mature and demanding: their grid connection rules, their commissioning frameworks and their construction practices have no direct equivalent in the Group's French or Italian experience. To support this acceleration, SIREOS is creating, within the Group Strategy & Development Department, a technical capability dedicated to opening new markets.

You give the commercial team the technical confidence it needs to commit quickly. 3) Technical preparation of bids Carry out the preliminary design and sizing of solar PV and storage installations: layout, energy yield, concept drawings, grid connection. Build and challenge the cost estimate: quantities, country cost assumptions, contingencies, optimisation variants. Support the commercial and legal teams on the technical annexes: scope and interfaces, performance ratio and guarantee tests, acceptance protocols, site conditions. 4) Commissioning and compliance processes Define, for each country, the applicable commissioning process: energisation procedures, grid compliance tests, tests witnessed by the grid operators. Identify the roles, authorisations and certifications required from those working on the territory concerned. Integrate these requirements from the b
