3. Introduction
• Solar has become one of the most promising
sources for electrical energy production all
over the world.
• Solar energy sources provide a clean, feasible,
and cost effective alternative as they dont use
fossil fuels in the energy production.
• MPPT is a method of tracking the maximum
possible power out of solar energy cells.

4. Principle of Solar cells
A solar cell is an electronic device which directly
converts sunlight into electricity. Light shining on
the solar cell produces both a current and a
voltage to generate electric power.

5. * When the photon of light hits the cell, the energy of
the photon is absorbed by the electrons.
* Electrons migrate from their position through the
possible bath returning back to the positive pole.

8. MPPT devices and algorithms
• MPPT is using DC-DC converters controlled
through special MPP tracking algorithms.
• The MPPT algorithms track the point on the I-
V curve that corresponds to a maximum
power and the converter use it as reference
point.

• Hill climbing techniques
• Fuzzy logic control algorithm
• Neural networks control
• Fractional short circuit control

MPPT, and its main algorithms.
• MPPT is the main responsible for the
high effecieny solar systems.
