Solar PV System Sizing

Technical Solutions provides engineering sizing studies for solar PV systems — determining the optimal system capacity, configuration, and component selection based on the client's specific requirements, site conditions, and economic objectives.

Service Overview

Proper system sizing is the foundation of a successful solar installation. An undersized system fails to meet energy objectives; an oversized system wastes capital. Technical Solutions provides independent engineering sizing studies that determine the right system capacity based on rigorous analysis of the client's electricity consumption, site characteristics, and financial parameters — not on equipment inventory or sales targets.

Scope of Work

• Load analysis — reviewing electricity consumption data, demand patterns, and load profiles
• Solar resource assessment — site-specific irradiance data, shading analysis, and orientation evaluation
• System sizing — calculating PV array capacity, inverter ratings, string configurations, and cable specifications
• Performance modelling — yield simulation and performance ratio estimation using industry-standard tools
• Financial analysis — payback period, return on investment, and levelised cost of energy (LCOE)
• Component recommendations — module, inverter, and mounting system selection based on technical and commercial criteria
• Engineering report with complete sizing results, calculations, and recommendations

Deliverables

• System sizing engineering report with methodology and assumptions documented
• PV system single-line diagram
• Yield simulation results with monthly and annual production estimates
• Component specification summary with recommended makes and models
• Financial analysis summary (where requested)
• Roof or ground area layout showing proposed array arrangement
