INTRODUCTION
The SOLAR-500 can be used in Quality Control for Production Line, Warehouse
or Site of Installation.
Manufacturers of solar panels can test the characteristics for quality control
purpose in the production line. Due to the advantage of portability of the
unit, quality inspectors can randomly pick samples of solar panels and test
them in the warehouse to assure quality before shipment.
Installation engineer can randomly test samples of solar panels at site to verify
the quality of solar panels used at site of installation.
Example A: Identify the Solar Power System Requirement
Measure the actual maximum power (Pmax), voltage (Vmaxp), and current
(Imaxp) at maximum power. Instead of using the rated maximum power, the
system designer needs to be aware of the actual solar power from the solar
panel under actual operating condition. So designer can actual know how
many pieces of solar panels are required to generate specific power.
The voltage and current under actual operating condition (in the morning, at
noon, and in the afternoon) are required for system designer to design the
optimal charging system, so most of the solar power can be absorbed and
stored in the battery.
Users can test the characteristics of solar panel at different time of day
and store the data. Then design can know if the solar system can generate
appropriate power at any time.
