I’m preparing to install a full-scale commercial solar array and need a seasoned designer who can take the project from an on-site assessment through to stamped construction drawings. The first priority is a thorough site visit: shading analysis, load profiles, roof and ground-mount feasibility, and interconnection options must all be documented. From that data you’ll develop the optimal system layout, electrical single-line diagram, production estimates, and a bill of materials that aligns with local code and utility requirements. Please fold any permitting nuances or utility coordination steps into your plan. When you respond, attach a detailed project proposal that breaks down your methodology, key milestones, and the software you rely on (Helioscope, PVsyst, AutoCAD, SketchUp, etc.). Include examples of prior commercial installations you’ve designed—especially those comparable in scale or complexity. I will review proposals based on the clarity of your approach to the assessment phase, your track record with commercial projects, and the completeness of your deliverables.

Dear Client, I am submitting this proposal for Commercial Solar System Design. We are a complete technical team specializing in solar energy systems, and we can handle this project from concept development to final technical delivery. Our strength is not only in system installation planning, but in producing a technically sound, financially viable, and professionally documented solution that can support real project decision-making. ## Why work with us We do not approach solar projects as simple equipment selection exercises. We approach them as engineering and investment projects. Our team has strong expertise in: - Solar PV system design and sizing - Battery Energy Storage System integration - Grid-tied system architecture - Energy yield simulation - Financial feasibility analysis - Engineering drawings and layout development We use professional industry-standard tools to ensure accuracy and credibility: - **PVSyst** for technical simulation, energy yield assessment, loss analysis, and performance validation - **PV*SOL** for detailed solar design, shading studies, and system performance modeling - **AutoCAD** for precise panel layout drawings, single-line diagrams, and installation planning This means the project will not be based on assumptions alone. It will be backed by proper engineering calculations, realistic generation forecasts, and clear design documentation. ## Scope of work We can deliver a complete proposal and technical study covering: - Solar PV system sizing based on rooftop area and load profile - Selection of suitable modules, inverters, and battery storage configuration - Estimated annual and monthly generation - Load analysis and energy usage optimization - Grid interconnection concept and technical compliance considerations - Preliminary review of Sri Lankan utility and policy context, including CEB and SLSEA requirements - Financial analysis including CAPEX, OPEX, payback period, IRR, and NPV - Tariff assessment under relevant Sri Lankan net-metering or net-accounting mechanisms - Environmental impact assessment such as annual CO2 reduction and avoided fossil fuel dependency - Engineering layouts and conceptual drawings prepared in AutoCAD ## Our approach Our work process is structured and professional: 1. We review the available project inputs, including load data, rooftop area, location, and client objectives. 2. We perform technical simulations using PVSyst and PV*SOL to estimate generation, losses, and system behavior. 3.
