Description
See how much power a solar pannel couldproduce, using your phone.
Also can be used for solar heating to see
what temperature rise you could get.
Has been tested with a solar panel see
graph in photos, quite good results using
a Galaxy S3 with a filter over the light
sensor.
Has many features see below.
->Displays Watts meter square,Power,kWh,kJ/h,oC/hour.
->Real time graph of Wm^2
->Set solar size in m^2
->Set pannel Efficiency
15-20% for Electricity
60% for solar heating
Depends on solarcells or collector
used.
->Water tank size Litres
estimate oC rise per hour.
>Cal light sensor mode
Most phones will saturate under full sunlight
max of 80,000LUX GS3
So idea use a filter over the sensor so that
full sunlight can be measured.
Should give >100W/M^2 in good sunlight.
1) Use a bright light source a lamp?
2) Set reference light level
3) Cover Phone light sensor with a
filter, I use a small plastic sheet
and tape.
4) Select "add filter and cal"
Now it will adjust the reading to the
refernce light level.
->Save to LOG file
->Count KWH and reset
First try the free app to test your phone has
a light sensor.
This is not a replacement for a Solar radiation meter
but I found gives a good estimate.
