The Current-Voltage
characteristic curves below show how the power can vary as the voltage
changes.
The inverter
controls the voltage to maintain the maximum power output as solar radiation
and cell temperature changes.
The cell temperature
is normally higher than the air temperature. The manufacturer indicates
that in full sun, the cell temperature is around 22 deg C higher than the
air temperature in a breeze of 1 m/sec.
Panel
Angle
The angle of the panels
to the sun angle affects the amount of energy collected. Ideally
the panels should be mounted on a two axis tracker that keeps the panels
"pointed" directly towards the sun no matter what the time of day or date.
However we only have adjustable racks that we intend to alter on the first
day of February, May, August and November ( ie; quarterly) to the approximate
optimum angle. We have calculated the optimum average angles for
Mt Beauty (37 deg South) and they are shown below for changing the angle
on the first day of the month or quarter. For other locations add
or subtract the difference between your latitude and 37 degrees South.
