Project brief
Eteria were appointed to explore the feasibility of maximising the rooftop solar photovoltaic (PV) potential of the site. The photovoltaic array was modelled using PV Sol Premium, an approved software for calculating photovoltaic installation generation based upon accurate solar irradiance data.
As part of the study, we evaluated different energy use scenarios including the current energy use, an increase to 125% and 150% of energy use.
Challenges
The existing roof comprises a curved metal roof structure with mechanical ventilation plant and rooflights incorporated. The photovoltaic array layout had to be coordinated with the existing roof and plant and factored into the overall generation calculations. The proposed photovoltaic panel dimensions were considered when coordinating the array layout to suit the existing roof plant.
Additionally, we provided the client with feedback on the implementation of a power purchase agreement (PPA) across the different scenarios and how this affected the financial results.
Calculation of the PPA revenues must be considered carefully due to the many variable factors involved including costs for maintenance, insurance, management and inflation.
Results
Eteria successfully delivered a feasibility study which provided the client with a complete assessment to enable them to make an informed decision.
The feasibility study quantified carbon savings, annual energy production and accurate financial figures. By undertaking this feasibility Eteria met the client’s objectives and assisted in improving the asset’s environmental credentials.
We are focused on applying practical, forward-thinking technologies to improve the efficiency and sustainability of assets and their operations. Our goal is to support carbon reduction by using innovation blended with traditional practices to ensure a robust solution.
