Feasibility Study
What is a Solar
Feasibility Study?
A solar feasibility study evaluates whether installing a solar energy system at a specific site is technically possible, financially viable, and environmentally beneficial. It’s usually done before investing in solar panels for a building, facility, or land. Below is a clear overview of the typical components.

What Are The Feasibility Study Steps
A solar feasibility study evaluates whether installing a solar energy system at a specific site is beneficial.
Feasibility Study Step One
Site Assessment
This step evaluates whether the location is suitable for solar generation.
Key checks include:
Solar resource availability (sunlight levels throughout the year)
Orientation and tilt of the roof or land
Shading analysis from trees, buildings, or terrain
Available installation area
Structural condition of the roof (if rooftop system)
Orientation and tilt of the roof or land
Shading analysis from trees, buildings, or terrain
Available installation area
Structural condition of the roof (if rooftop system)
Tools such as solar pathfinders, satellite imagery, and irradiance databases are often used in this process.
Feasibility Study Step Two
Energy Production Forecast
Using solar modelling software, the study predicts electricity generation.
Outputs typically include:
Annual energy generation (kWh/year)
Monthly generation estimates
Loss factors (temperature, wiring, inverter losses)
Monthly generation estimates
Loss factors (temperature, wiring, inverter losses)
These estimates rely on accurate historical solar irradiation data.
Feasibility Study Step Three
Energy Demand Analysis
This looks at how much electricity the site currently uses
Typical analysis includes:
Historical electricity bills (12 months)
Peak demand patterns
Daily / seasonal load profiles
Future energy needs (expansion, electrification, EV charging)
Peak demand patterns
Daily / seasonal load profiles
Future energy needs (expansion, electrification, EV charging)
This determines the optimal system size.
Feasibility Study Step Four
System Design Options
Engineers propose potential solar system configurations.
Examples:
Rooftop vs. ground-mounted systems
Fixed tilt vs. tracking systems
Grid-tied vs. hybrid vs. off-grid systems
Battery storage options

Feasibility Study Step Five
Environmental Impact Assessment
This quantifies environmental benefits.
Typical outputs:
Annual COâ‚‚ emissions reduction
Equivalent number of trees planted
