Solar photo voltaic powered lights called lanterns are considered to be alternative solution to
lighting needs. A typical solar lantern consists of small photo voltaic module, alighting
device, a high frequency investor, battery charge controller and appropriate housing. During
day time, module is placed under the sun and is connected to lantern through cable for
charging a typical lantern uses a 10 watt lamp. The expected life of lamp is 3 to 5 years.
2. STREET LIGHTING SYSTEM It consists
of two photo voltaic modules mounting frame , 4m long pole, battery box, tubular type lead
acid battery, charge, controller, investor and day light senses. Time module sensing is used to
switch on light on the evening. It works for one fluorescent tube light of 20 watts for whole
night.
OTHER USES OF CELLS
i. Solar cells are extensively used as main sources of energy for artificial satellites.
ii. They are widely used in toys and calculators.
iii. They are used as source of energy for radio or wireless transmissions at TV relay station, traffic
signals and stations in the remote areas.
PLACES
i. Ambaji apt, commercial complex, Devi dayal cross road, Mulund west, Mumbai, Maharashtra.
ii. Greenery solar power pvt. Ltd. 302, Sai paradise, G.G road, Vishnu nagar, Dombivali west,
district thane, Mumbai, Maharashtra.
iii. Boiline technology, sales office-3A, Alankar towers, old Mumbai, pune road, Dattawadi, Kalwa

The CIS Tower, Manchester, England, was clad in PV panels at a cost of £5.5 million. It started feeding
electricity to the national grid in November 2005.
4. SOLAR REFRIGERATOR TECHNOLOGY
Photo voltaic refrigerator operate on the same principle as normal compression refrigerators but
incorporate low voltage (12 or 24v) dc compressors and motors, rather than main voltage ac types.
