A new photovoltaic park has opened in Les Mées, in the southern department of Alpes-de-Haute-Provence. Spread across 36 acres, the park, built by Belgian firm Enfinity, joins several other plants built on the vast Puimichel plateau. By the end of 2011, solar panels will cover 200 hectares and produce around 100MW, making it the biggest solar array in France. Enfinity's €70m investment has included work to preserve the landscape with space for grazing and a system without a concrete foundation
