Standard Chartered Bank’s Sri Lanka head office is now generating clean, reliable energy thanks to a rooftop solar PV project designed and supervised by Vibhawa Consultants. From feasibility studies and detailed design to testing, commissioning, and performance analysis, we guided the bank every step of the way. This has helped them reduce energy costs, cut carbon emissions, and lead the way in corporate sustainability. Discover how we turned this renewable energy vision into reality. The Challenge Standard Chartered Bank had one clear goal: bring renewable energy into its head office operations, reduce its dependence on grid electricity, and contribute to its global sustainability agenda. But installing a solar PV system on a corporate rooftop is no simple task. It requires careful feasibility studies, accurate design, precise simulations, and thorough supervision. Every stage must be handled with technical accuracy to ensure the system performs reliably for decades. This is where Vibhawa stepped in, combining our engineering expertise with sustainability know-how. The Journey with Vibhawa 1. Starting with a Feasibility Study and Design Every strong project begins with a solid plan. Our team conducted a detailed feasibility study of the bank’s head office rooftop to assess the building’s suitability for solar panel installation. This included examining roof structure, load-bearing capacity, orientation, and shading. Once the feasibility was confirmed, the concept was turned into a detailed design for the solar PV system. This ensured that the installation would be technically sound, safe, and aligned with Standard Chartered’s energy goals. 2. Predicting the System Performance/Energy Yield with PVsyst Simulation Before even placing a single solar panel, we used PVsyst simulation software to model how the system would perform under real conditions. This advanced simulation allowed us to: Estimate the accurate energy yield. Predict system performance over the years. Identify the best configuration for maximum efficiency. Give the bank clarity on savings, return on investment, and contribution to sustainability targets. In simple words, PVsyst helped answer the question: “How much energy can we expect from this rooftop solar project?”. This ensured that there’s no guesswork in the design. 3. Preparing the Project Plans and Tender With feasibility and simulation complete, it was time to prepare the technical tender package, including a Bill of Quantities (BOQ). This step was crucial.  A strong tender makes sure everything is transparent, competitive, and up to international standards. By doing so, Standard Chartered could confidently select contractors and equipment suppliers, knowing the system would be built on the right technical foundation. 4. Acting as the Client’s Engineer and Supervisor Being the client’s engineer meant more than just overseeing paperwork. Our team represented Standard Chartered throughout the project lifecycle, ensuring the bank’s interests were safeguarded at every step.
