Solar consulting is professional advisory support that helps a business evaluate whether solar is viable, what system size makes sense, what the expected generation could be, and what the project steps should be before selecting vendors or committing capital.

A feasibility study typically includes site constraints review, load and consumption assessment, system sizing assumptions, energy yield estimation, risks, and a recommended next-step plan such as engineering, tendering, or turnkey execution.

PVsyst is widely used to estimate solar energy generation by modelling losses, shading, orientation, and equipment assumptions. It helps decision-makers compare scenarios and set realistic performance expectations.

At minimum: site location, monthly electricity bill or consumption, available roof or land area, basic photos if possible, and your project timeline. If you have a single-line diagram or load profile, that improves accuracy.

ROI is estimated using expected annual generation, tariff rates, project cost, operating costs, and assumptions such as degradation and downtime. A sensitivity check is also used to see how ROI changes with different tariffs or costs.

There is no single global definition, but many commercial and industrial solar systems start around 100 kW and can extend into multi-megawatt scale depending on site and consumption.

Approvals and compliance are typically handled during engineering and execution. Consulting can help identify the likely approval path and documentation requirements early, so the project timeline is realistic.

Timelines depend on data availability and site complexity. A basic assessment can be fast, while detailed modelling and documentation can take longer for larger or more constrained sites.

Solar consulting focuses on evaluation and decision support. EPC is execution, meaning engineering, procurement, construction, and commissioning. Consulting helps you enter EPC with clarity on scope and expectations.
