NEED FOR SOLAR THERMAL IN

OFF-GRID MODE



Crude Oil caters to one fourth of India’s

primary energy



India imports 80% of its oil consumption



Why Solar Thermal in Off-grid mode?

~20% of this oil is used in industries in thermal

form at temperatures below 300°C

30-50% of this can be replaced by solar energy

resulting in:

Reducing a country’s Forex burden

Imparting energy security

Emission reduction of Carbon dioxide as well as

other pollutants

Developed completely

indigenous ARUN® solar

concentrator dish

Boasts of both R&D and

Engineering skills



ARUN® - Key Features

Small Footprint Area & Retrofits: The small

footprint area of ARUN® dish (3m x 3m per

dish) enables it to be mounted at locations

which have space limitations. It can also be

erected on rooftops of existing buildings.

Performance Guarantee: Clique Solar

guarantees the performance characteristics of

ARUN® dish.



ARUN® - Key Features

Non-Solar Hours Operations: ARUN® dish can

be augmented with a heat energy storage

facility for operation in non‐solar hours.

IBR Approval: ARUN® is the first IBR approved

Solar Boiler in India.

High Wind Bearing Capacity: ARUN® dish is

designed to operate in wind up to 10 m/s and

it can survive in wind speeds up to 45 m/s.



ARUN EconomicsAttractive investment economics

Simple Equity payback in less than 2 years

Accelerated Depreciation at 80% of residual asset value

Subsidy of Rs. 10L per dish

Sector specific economic indicators

Cost per kcal of energy delivered over the lifetime

Energy gain ratio (25 to 30)

Foot-print area (3m x 3m including integration)

Need to view this as an infrastructure investment – life is 25-30 years+
