Solar Industry In India Solar Cell and Module manufacture is the main story

Two ways to harness solar power Solar Power is concentrated and converted to thermal energy which is converted to electric energy Solar Power is converted to electricity using PV (Photovoltaic) effect Regain Paradise Foundation (www.regainparadise.org) P N P N

Solar PV: the Value Chain Solar Modules Solar Cells Silicon Ingot Silicon Wafers This part of the chain is Oligopolistic. Increase in the poly-silicon prices (200% in 2 years) has been a key issue in the industry. Prices have plummeted this year Regain Paradise Foundation (www.regainparadise.org)

Solar PV Companies in India Companies are playing in the fragmented part of the industry chain with Moser Baer trying to make some serious technology investments Solar crystalline modules Hyderabad Solar semiconductors Solar modules and systems Various BHEL PV modules (both crystalline and thin film – amorphous and CIGS) and systems Hyderabad Titan Energy Systems PV modules (both crystalline and thin film – amorphous and CIGS) Has also invested in Stion (a thin film company), SolFocus (CPV company), Solaria (high efficiency cells) Bangalore Moser Baer PV Hyderabad Location(s) Solar PV Modules & Systems . Also Solar thermal products Photon Energy Systems Products Company

Solar Systems “solar systems” is really applications! In India the story is largely around smaller applications

Solar Applications

Solar Lanterns/Lamps

Solar Lights

Solar Thermal

The case for Solar Lanterns/Lamps

1.6 billion people in the world have no access to electricity:

25% of them in India alone

Products are both handheld and headlamps

Lead to improvement of educational levels Leads to improved mobility in inaccessible areas Leads to empowerment of women

How does a solar lantern work?

Typically consists of:

A rechargeable battery

A photovoltaic solar panel

CFL/LEDs

A plastic body

It works by:

Solar energy is collected by the panel and the battery is charged

The battery size is typically enough for about 4-6 hour lighting

The light is equivalent to a 40W-60W light

Design innovation in solar lanterns has been largely around the capacity of the panel, the size of the battery, use of CFLs/LEDs to impact usability and life of unit.

How do Solar street lights work?

Typically consists of:

A photovoltaic solar panel

A rechargeable battery

A charge controller cum inverter

CFL/LED lamp

It works by:

DC electric current is produced from the panel

The charge control circuit controls the voltage and prevents damage

How does solar thermal work?

It works by:

Solar energy is collected in Collector

Thermic fluid (water or antifreeze) is heated in the adjoining tubes

The fluid can be used directly (if water) or used to heat water in another pipe

The water can be circulated via pumps (active systems) or by gravity (passive)

Collectors are of two types:

Flat plate collectors (A weatherproofed, insulated box containing a black metal absorber sheet with built in pipes )

Evacuated Tube (These collectors have multiple evacuated glass tubes which heat up solar absorbers and, ultimately, solar working fluid)
