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.

Usable roof area (m²)Monthly electricity bill (BDT/month)User-entered electricity tariff (BDT/kWh)Usable area per installed capacity (m²/kWp)Illustrative technical starting value; replace with a site-specific layout assumption.Annual specific yield (kWh/kWp/year)Illustrative technical starting value; replace with a site- and design-specific estimate.Generation used on site (%)Illustrative technical starting value; hourly load and generation data are needed to validate it.Grid emissions factor (optional) (kg CO₂e/kWh)Leave blank to omit the indicative operational emissions screen; enter a site-appropriate factor.

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.

BESS sizing + diesel displacement

Estimate battery energy, generator fuel displaced, recharge cost and operational emissions for the stated events.

Critical duty and battery design

Battery nameplate sizing includes the entered load factor, efficiency, usable depth of discharge and capacity reserve.

Critical load (kW)Required discharge duration (hours)Equivalent events (events/year)Average load as share of peak (%)Illustrative technical starting value; replace with measured duty data.Discharge-path efficiency (%)Illustrative technical starting value; use the selected system's warranted discharge value for nameplate sizing.Round-trip efficiency (%)Illustrative technical starting value; use the selected system's warranted round-trip value for recharge-energy estimation.Usable depth of discharge (%)Illustrative technical starting value; confirm usable limits with the selected system.Capacity available at design point (%)Illustrative technical starting value representing design reserve/retention; validate for the duty and life target.

Diesel, energy and emissions assumptions

Emissions are operational estimates from the factors you enter; lifecycle, upstream and embodied emissions are excluded.

Generator fuel consumption (L/kWh displaced)Diesel price (BDT/L)Recharge electricity cost (BDT/kWh)Grid emissions factor (kg CO₂e/kWh)Diesel emissions factor (kg CO₂e/L)

User-supplied installed cost and O&M

Use project-specific quotations. PCS sizing uses the entered critical peak kW as the screening power basis.

Battery installed cost — lower (BDT/kWh)Battery installed cost — upper (BDT/kWh)PCS installed cost — lower (BDT/kW)PCS installed cost — upper (BDT/kW)Annual O&M (% of installed CAPEX/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.
