1. Introduction
The digital solar power meter is a precision instrument
used to measure solar radiation in the field.
It is fully cosine corrected for the angular incidence of
solar illumination.
The solar power meter is compact, rugged and easy to
operate.
The solar sensitive component used in the meter is a
very stable, long-life silicon photovoltaic detector.

Applications :
The meter can directly measure the solar power radiated from
any direction, angle or position, and can be mounted firmly on
a tripod. The meter can also calculate the total solar energy
against elapsed time or calculate the average solar energy
per hour.
1. Solar Power Panel Industry:
The meter can be used to measure the solar power at the
installation to determine the best location, angle and
direction before fitting the solar panel.

2. Solar Power Research:
The meter can be used for solar power research and
development, as a tool of education and to check the
efficiency of solar cells.
3. Agriculture:
Vegetables, flowers and plants are influenced by sunlight,
especially when cultivated in a greenhouse. The meter can
measure the solar power and help optimize plant growth.
4. Solar transmission measurement:
The meter can measure the solar transmission of glass,
heat insulation papers, parasols, sunshades etc.
For example:
Compare the solar power radiation measured before and
after a sunshade is installed. The measured readings help
determine whether the sunshade material is good at
reducing the solar power transmission.
5. Construction:
The meter can check the solar radiation at any angle and
any time, which is helpful when installing sheltering
systems to control the indoor temperature efficiently and
save energy.
Electricity can be produced by combining the building materials
with the solar power panel. The meter can measure the solar
power radiation to obtain the highest efficiency.
