Solar PV Tool

May 6

The Solar PV Tool estimates the onboard energy output of photovoltaic systems based on system specifications, vessel location, and seasonal solar conditions. It calculates expected solar generation under clear-sky assumptions or user-defined irradiance profiles. The tool then translates solar output into fuel savings using specific fuel consumption (SFC) parameters, making it ideal for evaluating hybrid, off-grid, and maritime energy systems where solar power offsets auxiliary engine load. The tool is intended for Tankers and Bulk Carriers, but can be used by any ship type.
This tool enables shipowners, operators, technical managers, and energy analysts to assess the performance and impact of solar PV systems across different operating profiles and routes. It supports feasibility assessments, early-stage technical evaluations, and operational planning by linking solar yield directly to fuel and compliance cost savings.
The tool also enables scenario-based comparisons, allowing users to evaluate the effects of different system sizes, performance ratios, or locations over multiple days or seasons. A parameterized report of the analysis can be exported to support internal validation, stakeholder communication, or regulatory review. Use the tool for:
Fuel offset calculations – Estimate daily and yearly fuel savings enabled by solar PV generation, based on vessel operations and auxiliary load assumptions.
Solar yield benchmarking – Compare expected solar generation across different ports, voyage patterns, or seasonal conditions.
Hybrid system integration – Simulate solar contribution alongside auxiliary generator operation and assess impacts on runtime and fuel demand.
Emission reduction analysis – Quantify the potential CO₂ savings from solar PV and support decarbonization strategies under IMO and EU regulations.
Technical and investment planning – Create structured technical outputs to inform C-level decisions, pilot projects, investment cases, and renewable energy roadmaps for vessels.
