Solar PV Panel Cooling Study: Water Film vs Fin and Fan
Approx. component budget: Rs. 6,000 - 11,000
Objective
Find how much extra electrical output a cooled panel gives, after subtracting the pump or fan energy.
What you will build
Two identical small solar panels (20-50 W), one with a water-film or fin-and-fan cooling arrangement, a small pump or fan, temperature sensors and voltage/current logging.
Results you can expect
- Panel temperature and power vs time for both panels
- Percentage gain
- Net gain after pump power
- Effect of ambient temperature
What you will learn
How temperature affects solar cells, heat removal methods, energy balance and data logging.
Tools and notes
Arduino with current/voltage sensors, Excel. Keep all electrical connections dry and insulated around the water.
Resume points from this project
- Built and tested Solar PV Panel Cooling Study: Water Film vs Fin and Fan; objective: find how much extra electrical output a cooled panel gives, after subtracting the pump or fan energy.
- Measured and analysed panel temperature and power vs time for both panels and percentage gain; wrote the report and presented the results in a viva. Add your own numbers: [x].
Replace [x] with your own measured results. Write only what you really did.
