What is Solar Powered Housing? 3 A house which generates electricity by means of solar energy is known as Solar Powered house.
Why Solar Energy? 4 Solar energy is available through out the days in most of the year. Its free of cost. It’s a renewable source of energy. Solar cells do not produce noise and they are totally silent. They have long life time They require very little maintenance as there is no moving parts.
Solar irradiation map of India. 5 Geographical Location: India being a tropical country receives adequate solar radiation for 300 days, amounting to 3,000 hours of sunshine equivalent to over 5,000 trillion kWh.
Working of Photovoltaic cell 6 Photovoltaic cells are made up of semiconductors like silicon. When light shines on the solar cell a percentage of this solar energy is absorbed into the semiconductor material. This energy now inside the semiconductor knocks electrons loose allowing them to flow freely. It also have one or more electric fields that force electrons to flow in one direction. N type semi conductor Depletion Layer P-type semi conductor
Equipments used in Solar Powered Housing 7 Solar Panel: A solar panel is a set of solar photovoltaic modules electrically connected and mounted on a supporting structure which generates electricity using solar energy Inverter: Since the electricity generated by solar energy is direct current (DC), and most household appliances require alternating current (AC), an inverter is necessary to change the current from direct current (D/C) to alternating current (A/C).
Equipments used in Solar Powered Housing 8 Battery (for off grid system): It is used to store electricity so that it can be used as a back up power when the panel is unable to produce electricity. Net Metering (for grid tie system): A measuring meter which will calculate how much energy you have taken from the grid and also supplied to the grid.
Solar Charge Controller: Controls the flow of electricity between the module, battery, and the loads. Prevents battery damage by ensuring that the battery is operating within its normal charge levels. If the charge level in the battery falls below a certain level, a "low voltage disconnect (LVD) will cut the current to the loads, to prevent further discharge. Likewise, it will also cut the current from the module in cases of overcharging. 9 Equipments used in Solar Powered Housing

Maintenance of Solar Panel 14 Solar PV systems are durable and do not require regular maintenance The only maintenance to be done regularly is to clean the dust particles deposited on the panels which can be done by showering water on the panel from the lower floor.
Life Span of Solar Panel 15 The output of the solar panels degrades by about 0.8% every year. Solar Systems modules have 25 years of useful life with 80 per cent of power still available at the end of that time period.
Cost of Solar Panels 16 The range for a 1 KW system quoted at the expo by various solutions providers is between Rs. 1.20 lakhs to Rs. 1.8 lakhs. Cost of 3750W solar system is up to $6756 which is around 4.3 Lakh
Why to use solar power system 17 Solar power reduces your carbon footprint. As calculated the coal left will last only for 109 years. According to the IEA Clean Coal Centre, there are over 2300 coal-fired power stations worldwide as per 2011. The average household generates 7.4 tons of carbon dioxide per year through electrical use. Temperature of the earth has started to increase Since the early 20th century, the global air and sea surface temperature has increased about 0.8°C (1.4°F) Due this high emission of carbon dioxide the Glaciers have started melting which will result in rise of sea level by 23 inches within the next 100 years which in result will drown many areas of the planet.
However, as technology increases, solar prices fall, and electricity prices rise, this may become a more economical solution. I also greatly reduces the amount of harmful emissions. 18 Conclusion

21 What is a Solar Car? A solar vehicle is an electric vehicle powered by a type of renewable energy, by solar energy obtained from solar panels on the surface of the vehicle.
22 History of Solar Car First Solar Car was invented in 1955 by Willam G. Cobb. That was called “SUN MOBILE”. It had 12 PV cells and the size was about 12 inch. Sun Mobile(first solar car)

24 Solar Cell A solar cell converts solar energy to electrical energy. Photons in sunlight provide the energy that moves electrons from one layer of a semi-conducting metallic wafer to another. The movement of the electrons creates a current. The most common solar cells function by the photovoltaic effect. “Photo” means light and “Voltaic” means electrical current or electricity.
25 Working Principle of Solar Cell When sunlight falls on the PV Cell, it absorbs the energy from photons and free the electrons from the Semi-conductor. A flow of electrons takes place which produces an electricity.
26 Power Trackers Power trackers condition the electricity coming from the solar array to maximize the power and deliver it either to the batteries for storage or to the motor controller for propulsion. When the solar array is charging the batteries, the power trackers help to protect the batteries from being damaged by overcharging.
27 Electric Motor An electric motor is a device using electrical energy to produce mechanical energy. An electric motor is the basic and the most important part of a solar car. It should work with optimal power and the efficiency should be high. It is used to drives the wheels.
