A solar
simulator allows us to test solar systems independent from
current weather conditions and time of day. This means
that solar research can happen at an accelerated rate
because of the amount of time able to study a system with
constant testing conditions. The simulator creates
artificial sunlight using xenon-arc lamps. These lamps
produce similar quality light to that of the sun. With the
help of parabolic reflectors, this light is made into
direct beam radiation with intensity close to 1 sun. By
making direct beams of light we are able to test systems
that concentrate sunlight as well as those that do not.
The lights are arranged in an array to produce a large
area for testing. This area is adjustable by adding or
subtracting lights in the array but is ultimately limited
by the size of the room.
