What is Solar Energy..? Solar energy it's a light and heat directly from the sun,from Solar we can harvest many ways of source. Solar Energy gives us many uses that can form according to consumer neess,like Solar Drying kit,Solar Cooking kit,Solar heating kit. The simple example is processing the light and heat from the sun we can get electricity by using Solar Panel photovoltaic. And we can gain heat by mirror photovoltaic,so Solar energy it's important to people's development.
How Solar Panel works..? According to the light from the sun up to the solar panel,it produce electricity when heat meets with Solar Panel Cells. The size of solar panel it's depend on a certain uses,so the demands of consumer will answer a question of what panel size will fit. A size of solar panel is measured by its power, SI Unit is Watt(W),example 60W.
Why Solar Power uses is better than other Electricity resources on off grid energy..? As we know that, a world is now covered with many sources of electricity,but here I will explain you why Solar Power is most better: 1.It's clean and safe source, 2.It's very cheaper and once purchased product, 3.You can depend on it for your home activities, 4.It's first priority on demand for off-grid homes, 5.It has small rist of electricity shock,so it's safe for house burnt. Disadvantages of Solar Power: Every good thing had its demerits/disadvantages,and these are among of them: 1.Solar Panel can't save the charge itself,so you have to connect with Direct Current Battery (DC Battery). Battery depends on it's power according to certain uses/consumption, power of battery storage measured with Current,it's SI Unit is Current=Ampire*Hour (AH),example 50AH. Battery Voltage can be 12VDC, or 24VDC,depends to demands.
2.Solar Panel efficiency affected by bad whether season like clouds,rain,or strong wind. 3.Solar Panel depends on sunlight location and availability,meaning that not any house loof can fit to produce electricity by solar panel. Devices/Equipments that completes Solar Power System: 1.Battery This is device which store the charge converted by solar panel during sun light,so that storage charge can be used at night time.
2.Battery Charge Controller As called name Charge Controller is device which minimizing the charge from Solar Panel to the battery according to its capacity. It depends on power of solar panel and battery, it measured with Current,SI Unit is Ampire (A). Example,panel is 100W,Battery is 80AH 12V,how to get current of Control charge.Formula, Power (W/Voltage (V)=Ampire(A), 100/12=8.33A,approximately(~)=10A.
The formula used to calculate rating current between Solar Panel and Battery is, Ampire Current(A)=Power Watt/ Battery Voltage.For example, Solar Panel is 100Watt,and Battery is 12Voltage DC, so 100Watt÷12V=8.3A. By accumulation you can use 10A Charge Controller. 3.Inverter According to the storage capacitance of Battery may underpaform to uses,not only that but another reason is many appliances are made to use Alternating Current (AC),so you need inveter to convert Direct Current (DC) from Battery into 240VAC.
4.Power Storage Uses/Appliances The stored charge of Solar Power may finally used to various activities, like Lamp,Tv,Fan,Charging small devices like Phones, Cameras, etc.
