Lens Based High Efficient Solar Panel using MPPT Algorithm

The energy produced by the non renewable resources in our country is in verge of extinction, so the future world needs the energy.

Other renewable energy are seasonal one except the sun, solar energy can be used to get stable power supply throughout the year.

In recent trends researches has been widely done to minimum its initial cost and for effective power production.

Overview

Concept

With Fresnel lens:

We use Fresnel lens to increase the intensity of the sunlight on the solar panel.

It can be used as collimator and collector.

With mirror:

Here the mirror Is placed at an angle of 15 deg.

Here the front side direct sunlight and backside gets reflected light from the mirror.

Comparison of solar panel with mirror & Fresnel lens

MPPT is the simple method implemented to trap the maximum power from the solar panel.

The MPPT algorithm is implement by means of FGPA microcontroller.

There are different methods of implementing the MPPT algorithm such us:Incremental conductance methodPerturb and observe methodFractional SC currentFractional OC voltageNeural networksFuzzy logic

What is meant by MPPT?

SMALL BLOCK DIAGRAM OF WHOLE CONCEPT

This block diagram represents the simple process of solar panels and some converters with using MPPT algorithm.

STATUS OF LDRs STATUS OF LDRs

LDR 1 is illuminated more than LDR 2 Motor will run in Anticlockwise direction

LDR 2 is illuminated more than LDR 1 Motor will run in clockwise directionBoth LDRs illuminated to same light Motor will be stoppedBoth LDRs are exposed to darkness Motor will be stopped

LDR• A high resistance semiconductor whose resistance decreases

with increasing incident light intensity.• When light falls on such a semiconductor, the valence electrons

receive the light energy incident and jump to the conduction band.

• The conductivity of the device increases, decreasing its resistivity.

CONDITIONS INDICATION MESSAGE SENT TO THE MOBILE

When the battery is full Battery fullWhen the battery is half full or medium Switch off the heavy load or switch off

the load that is not necessaryWhen the battery is empty Battery is empty so use only the light

loadIf the battery is full and performance is good

Solar panel works in perfect manner

Monitoring of the solar panel using module• Here the solar panel can be monitored continuously to improve the

performance and to drive the maximum power out of its performance can be checked continuously by noting the power output at various time either manually or remotely.

The main objective of this paper is to increase the efficiency of the solar panel which can be implemented in practical case.

I tried my level best to increase efficiency of the solar panel with the simplest method.

The solar tracking system contains of LDR,fresnal lens,using MPPT algorithm to track the maximum power from the solar panel.
