i have designed an physics experiment as below:
Aim:
The aim of this experiment is to use different shapes of mirrors to reflect the sunlight onto the solar panel, and find out which shape of mirror makes the most efficient solar power of the solar panel.
Apparatus:
A solar panel, Mirrors (maybe shape of circle, triangle, rectangle, ect..), wires, An ammeter
A voltmeter
Method:
1. Set up a circuit to connect the ammeter and voltmeter to the solar panel
2. Put a mirror at 45°angel of the solar panel
3. Record the voltages and currents
4. Put the mirror at 90°of the solar panel
5. Record the voltages and currents
6. Repeat step 5 for different shapes of mirrors
i have 2 problems now:1.if i put the mirrors at different angles,i don't know what angles should be chosen to test(i am afraid i miss the best one)2.i have thought of do one shape of mirror each day,start from 9 am to 4pm(the angle of the sun is changing),i am considering the weather won't be the same every day.what should i do?
