Invitation to Chinese EPCF partners

Solar power in Iran100 MWp

We invite a priced proposal for engineering, procurement, construction and financing of a solar plant with 100 MWp of DC module capacity. Site selection and final terms follow the partner’s response.

Iran, mapped by solar yield

The red scale maps modelled specific PV yield from the Global Solar Atlas. Compare regions at this stage. A parcel will be selected after the partner’s technical and financial response.

Values correspond to sample cells near the reference cities. Final design requires land, grid, dust and water assessments.

Irradiance and performance

Daylight through the year in Yazd

Select a month to see mean hourly global horizontal irradiance in a typical meteorological year and how daylight varies through the day.

From sunlight to outputThis profile measures sunlight. Converting it into delivered electricity requires module tilt, temperature, soiling, inverter efficiency and the grid export limit.
Operations in an arid climate

Dust and water in the operating budget

Navoi’s appraisal estimated 4,620 m³ of water per year for wet cleaning. Choose a cleaning schedule using measured losses, rainfall, available water and the value of recovered output. Maintenance helps preserve performance; output still varies.

Connection and power delivery

What does storage deliver?

SATBA reported a large-plant connection requirement of at least twenty per cent of capacity for two hours. On a 100 MW connection basis, the example gives 20 MW and 40 MWh. The connection approval determines the final basis.

Electricity sales in Iran

Who buys the electricity?

Choose a sales route to compare its pricing basis, contractual commitments and payment risk.

Three prices, three uses

All figures are in IRR/kWh. The billing rate is a consumer charge. The other two values are historical market averages.

Project economics

Costs and performance in practice

Uzbekistan’s Navoi plant provides a working comparison. Its completion report separates total project cost, EPC expenditure and delivered output.

Uzbekistan · Commercial operations, December 2021

The Navoi plant

The contract used a 100 MW benchmark. The completed plant had 132 MWdc of modules and 115 MWac of installed equipment. Construction took one year.

Capital and repayment

Use these proposed terms to price the offer. Land rights, the cash contribution and bank acceptance each require supporting documentation.

Plant technology

Equipment and services

Two examples for comparing datasheets. Check module power, string voltage compatibility and AC output at site temperature for the chosen design.

Research dossier

The Iran solar research dossier

Seven technical and commercial chapters with original documents, reference data and limits of comparison.
