Commercial & industrial energy solutions
Stonegrid Engineering combines technical advisory, energy analysis, engineering design and commercial evaluation to develop robust Solar PV, BESS and hybrid energy projects for commercial and industrial clients. We support projects from feasibility and concept development through procurement, implementation and commissioning.
Managed energy service for business
A structured Solar PV and battery service can combine assessment, equipment, monitoring, maintenance and agreed commercial terms in one plan. Depending on project suitability and approval, a no-upfront-capital structure may also be available.
