Sustainable power source house is worked under sun based power with sunlight based following framework to accomplished 99{0db87490562065f9000963154745e00485813aab81ae882bf33fb536630d64aa} sun oriented effectiveness in residential home

Scope objective

The significant reason for sun-powered following framework is to assemble the greatest measure of energy supply by methods for following the sun based board. When the framework is exchanged on, the sun oriented board goes to the underlying position, i.e. towards east.

Working principle

There are four LDR which is set each in 45o to continue following of the sun from sun ascend to sun fall. When the light falls on the main LDR, the flag will be sent to IC 89C51 microcontroller. This thusly controls the stepper engine position i.e. to start with quarter 0-45o.

As the sun rises when the daylight falls on the second LDR i.e. second quarter 45-90o, consequently first LDR is put off and the second one gets on. The flag from the second LDR goes to the IC and thus goes to the stepper engine to change its position, i.e. 45-90o. A similar procedure goes ahead till the sun tumbles down. So we can track the sun persistently. The electric vitality accordingly got from the sun-powered cell goes to a capacity cell/battery and it is put away. At the point when this vitality is required it is gotten by utilizing an inverter. It is additionally modified, in regards to the season of load on and stack off. here load is movement light with clock control unit


1) No need for electric energy to work

2) No need of wiring

3) It is a compact one


1) Little piece expensive than ordinary LIGHTING

2) Operates up to the quality of the battery
