Most refrigerators include a freezer compartment for ice pack freezing. Other systems have separate units
to provide solely for refrigeration or freezing. Available size range between 10 and 85 liters of vaccine
storage capacity with ice production rates up to 6.4 kg per 24 hours.
A typical refrigerator layout
PERFORMANCE
The energy consumption of photo voltaic refrigerator is typically 400-800 watt-hours per 24 hours for a
100 liters refrigerator without ice pack freezing and at +32c ambient temperature. At +43c ambient
temperature and freezing 2 kg of ice pack per 24 hours the energy consumption of same refrigerator
would rise to about 900-1900 watt-hours per 24 hours. It is very important not to overload a solar
refrigerator as this increase energy consumption considerably.
COMPARATIVE COSTS
A solar photo voltaic refrigerator cabinet only is likely to cost around us $1300-2600 and will cost more
to install than kerosene unit. A kerosene refrigerator will cost only us $650-1300 but will use 0.5-1.4
liters of fuel per day, require frequent maintenance and have a shorter life. In general, life cycle costs are
approximately the same for solar and kerosene refrigerator.

CONCLUSION :ADVANTAGES OF SOLAR ENERGY
i. Solar energy is an extremely large and inexhaustible source of energy.
ii. Solar energy is a clean source of energy and it does not cause pollution.
DISADVANTAGES OF SOLAR ENERGY:
i. Solar energy is a dilute source of energy. Even in the hottest regions on the earth, the solar
radiations incident per second on one square meter of earth‘s surface is less than 1000 Joules.
