1. EXPERIMENTING THE SUN Experimenting with a solarpanel

2. Sun table: The measuring was smallest in the shadow With load at. 9.00 Voltage (V) Current (A) Effect P=U*I (W) In the sun19,40,0951,8 In the shadow1,30,0180,02 Angled from the sun 19,30,091,7

3. With load At. 12.30 Voltage (V) Current (A) Effect P=U*I (W) In the sun200,091,8 In the shadow18,50,0170,32 Angled from the sun 18,50,0891,65

5. Different measuring at. 12.30 Voltage (V) Current (A) Effect P=U*I (W) In the sun without load 1,36,88,84 In fluorescent lamp 0,73,152,21 In darkness10 mV00 In shadow without load 0,85,34,24 We tried to measure voltage and current in the sun and in the shadow outside, in the darkness and in the light of a fluorescent lamp inside. We did these measurements without load, that is a short circuit.

6. We had started another project before this one with a wind power station but it failed. The construction didn´t work as it should have. But we´ve got some nice pictures from the lessons that we worked on buliding it. The problem was that the wind mill didn´t spin when we took it out or blew at it with a hair drier. It would have needed more powerful wind.
