  • Review of grant compliance

Through the Greensolver’s audit of the project, the proposed system was found to be aligned with industry standards. Minor risk from the selected site was identified, with mitigation investigated and proposed. The Financial Model was found to require revision and was therefore updated to better reflect local conditions.
