Just wanted to share my first experience with solar power!

I have a room which isn’t very well ventilated, so I decided to build in a small cooler. To keep it simple, I decided to connect the cooler directly to the panel.

The panel is 5W and can produce 0.28A at 18V with maximum sun. I bought it on aliexpress.com and it was 20 USD with free shipping 😉

Related power 5W
Voc 22.41V
Vop 17.9V
Short circuit current (Isc) 0.3A
Working current (Iop) 0.28A
Output Tolerance ±3%
Temperate coefficient of Isc (010+/- 0.01 )%/
Temperate coefficient of Voc – (0.38 +/-0.01 )%/
Temperate coefficient of power Voc -0.47%/?
Temperature range -40?to +80
Frame Heavy duty aluminum
Kind of connection waterproof junction box, can be customized
Guarantee of power 90% with in 10 years  80% with in 25 years
Kind of glass and its thickness Low Iron, high transparency tempered glass of 3.2mm
SLA Battery Voltage 12V
Size 255 x 194 x 15mm

The cooler is a 24V, 0.31A cooler, so at 18V it will use 0.24A. Perfect fit for the panel!

The system works great. At about 8 am the cooler starts spinning and runs continuously until about 4 pm!
