When a light of certain frequency falls on the surface of a metal Electrons will absorb the energy If incident light energy is greater than the work function(minimum energy required to remove the loosely bound valence electrons)of the metal Then the photo electrons will be emitted and The excess energy is converted to the kinetic energy of electron. When solar panels are placed in the sunlight, photons will strike the surface and emits electrons. As a result electron hole pair is created in the solar cell. When external circuit is connected to the solar cell , electrons flow in the circuit and the current is generated.

In a solar rooftop system, the solar panels are installed in the roof of any residential, commercial, institutional and industrial buildings. This can be of two types (i) Solar Rooftop System with storage facility using battery, and (ii) Grid Connected Solar Rooftop System.

A Solar Water Heater is a device which provides hot water for bathing, washing, cleaning, etc. using solar energy. It is generally installed at the terrace or where sunlight is available and heats water during day time which is stored in an insulated storage tank for use when required including mornings. A Solar Water Heater comprises of an array of solar collectors to collect solar energy and an insulated tank to store hot water. Both are connected to each other. During the day time, water in solar collectors gets heated which is either pumped or flown automatically on thermosiphon principle to the storage tank. Hot water then stored in the tank can be used for various applications.

Solar power, or energy created by the sun, can be harnessed in a number of ways, including through solar panels that convert the sun's rays into electricity. In the case of a solar pump, solar energy is converted into electricity and fed to a pump that circulates water. These types of units can be used in swimming pools, fountains and larger agricultural projects There are two main types of solar pumps. Surface pumps sit above ground and move water through pipes. These are handy for moving large quantities of water at a slow pace. Surface pumps are commonly found on farms or large irrigation systems where water needs to be moved from a lake or other body to fields or landscaping. There are also submersible solar water pumps. These units are installed underground, but the solar panels are connected above ground. Submersible pumps are used to move water from inside wells to the surface.

A PV system is made up of different components. These include PV modules (groups of PV cells), which are commonly called PV panels; one or more batteries; a charge regulator or controller for a stand-alone system; an inverter for a utility-grid-connected system and when alternating current (ac) rather than direct current (dc) is required; wiring; and mounting hardware or a framework.

A PV system that is designed, installed, and maintained well will operate for more than 20 years. The basic PV module (interconnected, enclosed panel of PV cells) has no moving parts and can last more than 30 years. The best way to ensure and extend the life and effectiveness of your PV system is by having it installed and maintained properly. Experience has shown that most problems occur because of poor or sloppy system installation.

A photovoltaic (PV) system needs unobstructed access to the sun's rays for most or all of the day. Shading on the system can significantly reduce energy output. Climate is not really a concern, because PV systems are relatively unaffected by severe weather. In fact, some PV modules actually work better in colder weather. Most PV modules are angled to catch the sun's rays, so any snow that collects on them usually melts quickly.

The size of solar system you need depends on several factors such as how much electricity or hot water or space heat you use, how, the size of your roof, and how much you're willing to invest. Also, do you want the system to supply your complete energy usage or to supplant a portion of your higher cost energy usage? You can contact a system designer/installer to determine what type of system would suit your needs.

People decide to buy solar energy systems for a variety of reasons. For example, some individuals buy solar products to preserve the Earth's finite fossil-fuel resources and to reduce air pollution. Others would rather spend their money on an energy-producing improvement to their property than send their money to a utility. Some people like the security of reducing the amount of electricity they buy from their utility, because it makes them less vulnerable to future increases in the price of electricity. If it's designed correctly, a solar system might be able to provide power during a utility power outage, thereby adding power reliability to your home. Finally, some individuals live in areas where the cost of extending power lines to their home is more expensive than buying a solar energy system.

It is a grid interactive and hybrid type inverter which is capable of supplying solar power when the grid power is off. So this system works as a power back up also.

INet metering is a policy that allows homeowners to receive the full retail value for the electricity that their solar energy system produces. The term net metering refers to the method of accounting for the photovoltaic (PV) system's electricity production. Net metering allows homeowners with PV systems to use any excess electricity they produce to offset their electric bill. As the homeowner's PV system produces electricity, the kilowatts are first used for any electric appliances in the home. If the PV system produces more electricity than the homeowner needs, the extra kilowatts are fed into the utility grid.

Rooftop Solar power is much cheaper than power from Diesel Generators. Solar PV generates power at a cost of about rs. 4.5-5/kwh while diesel generates power at about rs. 16/kwh, keeping. Whether Solar power can replace your diesel consumption entirely depends on a number of factors such as the nature and timing of the load, the extent of load shedding, the area of roof available, exposure duration of clear sun. For residential structures, where peak load is not so high, diesel genset can completely be eliminated by solar rooftop.
