Sun Tracker Solar Panel

Introduction: 
 As we know that energy is very important in our life. In the modern age, life is complicated without electric light. Energy is two types, 1.Renewable 2. non-renewable. Renewable energy is unlimited for example solar energy, wind energy etc. But non-renewable energy is limited for example nuclear energy, fuel energy etc.In all of this solar energy is very simple and very useful. We can use solar energy city and village as well as many other places. It is free from all type of pollution. If we use sun tracker solar panel then we found more energy.In present time in the market available programmable sun tracker solar panel which is costly as compare to Nonprogrammable. If we use without programming sun tracker solar panel which is made by the operational amplifier so this is very cheap as compared to programmable.

Keyword: Operational amplifier IC(741) Light dependent register (LDR), Register, Gear motor, solar panel etc.

Light Dependent Resistor 

Theory: 

 A light sensor is the most common electronic component which can be easily found. The simplest optical sensor is a photon resistor or photocell which is a light sensitive resistor these are made of two types, cadmium sulfide (CdS) and gallium arsenide (GaAs).when light rays incident on the LDR1, from fig-(ii) V1 would be greater than the voltage V2 so the output of the op-amp will be negative and if

the sun moves to the right then V2>V1 then the out-put will be positive and if the sun is just above the both the LDRs then the intensity on both the LDRs will be equal i.e.V1=V2 so output of op-amp will be zero, hence we would be able to detect the movement of the sun.

Operational amplifier: We use second component 741 op amp as a differential amplifier .Is very important component for this making sun tracker. When v₁>v₂ then output voltage is negative and motor is move clock wise and when v₂>v₂ then the output voltage is positive and motor moves anti-clockwise and when v₁=v₂ then output voltage is zero then motor will be stopped.

ombination of LDR and Op Amp:

 If we combined figure (i) and figure (ii) so this look like given below figure (iii) . In morning time sun is on the LDR₁

Conclusion and Future Scope: It is very important and useful tools in present times and also in future. By our calculation and observation statistical that solar tracking system with single-axis freedom can increase energy output by approximately 20%.By dual axis sun tracking system we can increase energy about40%. In present time maximum place use not movable solar panel this very easy for making sun tracker solar panel. This is also use for equal voltage,negative voltage and positive voltage.
