design a Li-Ion battery charger to get maximum power from a
solar panel Power
available from a solar panel is heavily dependent on the operating
environment. Here's what you need to know to get charged.Solar
energy is an attractive energy source for powering portable
devices. For some time, it has been widely used in applications
like calculators and spacecraft. More recently, solar power
is being considered for a much wider range of consumer applications
including mobile phone chargers.
However, power available from a solar panel is heavily dependent
on the operating environment. This includes such things as
light intensity, time and location, etc. Therefore, batteries
typically are used as energy storage elements. They can be
charged when extra power is available from the solar panel,
as well as to power the system when the available power from
the solar panel is insufficient. How do we design a Li-Ion
battery charger to get the most out of the solar cells and
efficiently charge the Li-Ion battery? First, we'll discuss
the operating principle and electrical output characteristics
of a solar cell. Then, we'll cover battery charging system
requirements and system solutions for matching the solar cell
characteristics to get the maximum power from the solar cells.
Doing a quick check I
determined that the possible reason it had been tossed
is it had a short across the Solar inputs ... not knowing
how these
regulators work I decided to do a bit of reverse engineering.

it appears
that this device shorts the solar panel out when the battery
is
deemed fully charged. Because they also have a pair of blocking
diodes this
would certainly stop the charging however I wonder if this
is potentially
damaging to the solar panel.
Attempting to find an answer to that by reading specifications
on PV panels;
most specs give a short cct current, and an open cct voltage
and specify
that the operational voltage/current is somewhere in the middle
of that.
Being that they provide a Short cct spec sort of implies they
can be
shorted.
To make a long question short;
I am trying to understand;
A) Why shorting a panel is an acceptible way to shut off the
charging
B) Is there a Solar Cell Equivalent CCT (similar to a battery)
that can be Basically,
a solar cell comprises a p-n junction in which light energy
(photons) causes electrons and holes to recombine, generating
an electric current. Because the characteristics of a p-n
junction are similar to those of a diode, the electrical circuit
shown in Figure 1 often is used as a simplified model of the
solar cell's characteristics.
Figure 1: Simplified Circuit
Model of a Solar Cell
The current source IPH generates a current proportional to
the amount of light falling upon the cell. With no load connected,
nearly all the current generated flows through diode D, whose
forward voltage determines the solar cell's open circuit voltage
(VOC. This voltage varies somewhat with the exact properties
of each type of solar cell. But for most silicon cells, it
is in the range between 0.5V and 0.6V which is the normal
forward voltage of a p-n junction diode.
