After recapping what we’d achieved during the previous day, I set about measuring the effects of shading on the two 2 amp solar panels. After setting up the lighting unit I then measured the effects of the shading (using solid templates of different sizes) and saw how covering the panels (normally done by clouds or shadow) effects the amount of current generated. After initial teething problems I managed to measure the current, with four lights being used and got the following results:
|One Eighth Shading||0.54|
|One Eighth Shading||0.32|
I also found out that shading on various parts of the panel effected the performance of each panel differently, which showed that although the solar panel produces a current when the sun is not shining it doesn’t even produce enough power to light fully a 60watt light bulb. It also shows how powerful the sun really is. Once that was finished, I was shown how to fit MC4 connectors using a crimping tool and I made up two extension cables for the solar panels.
