solar charger controller

Device that will allow a solar panel to
efficiently recharge a DC battery. This is
accomplished by operating the solar panel at an
optimal power level regardless of the battery voltage.
The controller will vary the voltage across the panel
to find and maintain the maximum power point. The
circuitry also monitors the battery voltage level and
charges the battery using pulse width modulation
techniques.


Solar photovoltaic panels are becoming a more common way to provide electric
power to remote electronic devices. Ease of use and installation, power reliability (the
sun is not expected to stop shining soon), cost competitiveness with replacement of
non-rechargeable batteries, and long lifetime capabilities are all contributing to a higher
demand for solar powered devices. In addition, portable electronic devices, such as
cellular phones, laptop computers, and music playing devices are becoming more
prevalent. Charged batteries are the backbone of these products, and when individuals
are not near traditional electricity, an alternative means of charging must be present. A
solar photovoltaic panel meets this need.
