Enter your operating data to explore a preliminary scenario.

Assumptions and calculation method

Editable screening assumptions, not a site yield forecast. Capacity = area ÷ area per kWp. Generation = capacity × specific yield. Used generation is capped at annual site use; this annual cap does not establish hourly coincidence. Value includes self-consumed energy only, with no export income, CAPEX, O&M or financing. A survey, structural review and hourly model are required.

Illustrative starting values. Replace them with your site data before discussing a project.

Solar Energy

Evaluate rooftops or land against daytime demand, structural conditions and the connection strategy before committing to capacity.

Solar + Storage

Model solar output, site demand and battery operation together. Storage adds value when there is a defined energy-shifting or backup requirement.

YOUR NEXT STEP

Turn this requirement into a project brief.

Share your site, operating priorities and available data. Start with an assessment, arrange a survey where needed, then discuss the project scope.

ENGINEERING SCREENING

Explore a first-pass project estimate

Enter site data and your own commercial assumptions. Outputs update as inputs become valid; use Calculate Estimate for a deliberate refresh.

All calculations are indicative baseline estimates subject to detailed on-site power quality logging and engineering validation.

Industrial solar feasibility

Screen rooftop capacity, annual self-consumption value and indicative installed cost. No export value is assumed.

Site and demand

The area screen caps system capacity. Self-consumption is also capped by annual site energy inferred from bill ÷ tariff.

User-supplied commercial assumptions

Enter local quotations and tariff assumptions. The optional lifecycle screen needs both a period and a discount rate.

Installed cost — lower (BDT/kWp)Installed cost — upper (BDT/kWp)Annual O&M (% of installed CAPEX/year)Project period (optional) (years)Discount rate (optional) (%/year)

Complete the required assumptions to see a screening estimate.

These screens do not include financing, tax, battery or inverter replacements, degradation over time, export revenue, or a bankable forecast. Operational savings and emissions are estimates based only on the assumptions entered. Simple payback is first-year net operating savings against installed cost, held level; it is distinct from a full cash-flow model such as SAM discounted payback (see SAM financial models). Lifecycle value is shown only when period and discount assumptions are supplied; no LCOE is calculated.
