why we have to use solar energy now days ?

1- solar energy reduce power consumption of original energy and it means save fuel which leads to save money.

2- solar energy is environment’s friend so it have no emission in the air it keep air clean and fresh.

3- solar energy save environment from global warming it is called green power.

4- solar energy is playing a big role to create new jobs.

5- solar energy save the environment from the noise which produce from internal combustion energy which use fuel to generate electricity.

how to store electricity which made from solar panels during the day?

almost electricity which generate from solar panels we don’t use it in the same time but we can do it next time for example at the night and so solar energy systems provided by battery which store electricity and let you use the energy at any time you want.

but this way to store solar energy is most popular way to store solar power but not only way there were other systems for solar energy storage for example

1- thermal energy which generated from solar cells store in the heat capacity of a molten salt (the liquid form of an ionic compound like sodium chloride) at a high temperature and if you need electricity later the stored heat is transferred from the molten salt to water provided heat  exchanger to generate steam to drive a turbine.

2- the second way to store solar energy is employ sunlight to produce a fuel for example a photoelectrochemical cell uses solar energy to split water into hydrogen and oxygen gases, which can be stored as fuels. These gases are then recombined to generate electricity in a device known as a fuel cell.

what is the types of solar cells?
1-Monocrystalline Silicon Solar Cells

monocrystalline silicon are made out silicon igots and cylindrical  in shape to optimize performance and to low cost .

    the benefits of using this kind of solar panels are efficiency rates reaches to 15-20% and it could live longer time till 25 years warranty .

require small space and produce 4 times of power compare to other types.

2- polycrystalline silicon solar cells

this kind of solar cells discovered in 1981 and it based on polycrystalline silicone it made by melted raw silicone and pour it in to square mold after these process it cooled and cut looks like wafers.

manufacture this kind of solar cell is simple and cost low , waste silicone amount is less

3- thin film solar cells

and this type of cells efficiency reached to 13% it’s advantages are:

  • mass production is too easy
  • very good appearance make them more appealing
  • very sensitivity and large area not required.
  • it could be flexible for potential application.
Amorphous Silicon solar cells

this kind of solar cells used for small scale application such pocket calculator

Cadmium Telluride solar cells

its efficiency reached to 11% and based on cadmium telluride

how do solar panel work?

solar panels consist of two sides negative and positive (P/N)

rays from the sun contains a lot of photons when these photon strike the silicon which the solar panel made from enough energy knock electron leaving a hole negative charge are now free to move around but due to electric field in P/N conjunction make negative charge go only one way this way is N side and a hole is in P side negative charges (electrons) collected by metal finger at the top of the cell and flow making electrical circuits .

why solar cells made from silicon ?

silicon is semi conductor and so it is the best material to made solar cells.

how much do solar panel cost ?

usually the average electricity consumption at homes is one kilo watt per hour its about 730 hour per month and every kilo watt cost about 0.1 $ so per month 73 $.

this cost about home application only there were a large wide application it costs more than this price.

and it is very important to show the price for solar systems installation it ranges from $2.87 to $3.85 per watt.

and you have to know Most solar panels have a 25-year warranty that’s encourage people to built solar systems up at their homes.

is solar panels need direct sunlight to produce electricity ?

direct sunlight  not necessary to produce electricity from solar panel but it improve the efficiency and so amount  out put electricity increased .

to which limit can solar panels produce electrical power ?

Most solar panels have 200- or 250-watt capacities

how to measure solar power produced ?

Solar power is measured like all electricity—in watts (kilowatts, megawatts, gigawatts, and terawatts).

what is the  period of sunlight takes to contact with solar panels ?

Sunlight takes a little over eight minutes to reach Earth and a few seconds longer to make contact with your solar panels.

how can i use solar power when the sun isn’t shine or cloudy ?

When the sun isn’t shining, you can use a special battery as backup for your solar panel system. However, most modern solar units use net metering (a system hooked up to your city’s power grid that measures the difference between the energy you give back to the grid and the energy you use from the grid). For controlling energy deficits, net metering is an easier and cheaper method than storing excess solar power in batteries.

how using solar energy prevent pollution ?

Each year in America alone, over one million gallons of petroleum spill into waterways, oceans, and groundwater. That’s why solar power is so important—it can reduce pollution and harm to the environment.

Solar power does not create any noise pollution; solar panels silently create energy from the sun’s rays.

solar systems components :

1- solar panels

2- AC/DC inverter

3- controller

4- battery backup

5- grid (or not)

why inverter used in solar systems ?

converter or PV inverter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid.

what the types of inverters used in solar systems ?
  1. Stand-alone inverters, used in isolated systems where the inverter draws its DC energy from batteries charged by photovoltaic arrays. Many stand-alone inverters also incorporate integral battery chargers to replenish the battery from an AC source, when available. Normally these do not interface in any way with the utility grid, and as such, are not required to have anti-islanding protection.
  2. Grid-tie inverters, which match phase with a utility-supplied sine wave. Grid-tie inverters are designed to shut down automatically upon loss of utility supply, for safety reasons. They do not provide backup power during utility outages.
  3. Battery backup inverters , are special inverters which are designed to draw energy from a battery, manage the battery charge via an onboard charger, and export excess energy to the utility grid. These inverters are capable of supplying AC energy to selected loads during a utility outage, and are required to have anti-islanding protection.
