Is your property eligible?

Most commercial solar car park installers require a minimum of 30 parking spaces or a roof area of at least 500 sq meters to ensure financial viability for a fully funded PPA Model.

Our commercial solar ROI calculator helps you assess viability for offices, industrial units, logistics centres, and retail parks. Projects falling below these thresholds may still be viable via CapEx or Asset Finance models.
