This high quality 20W Solar kit includes:
- 20W polycrystalline solar panel
- 3A 12V/24V PWM charge controller
- Battery clips with 2m extension wire
The solar power kit can be used for powering various DC devices.
If you want to store the solar energy you may use a battery.
The battery should be bought separately.
The recommended voltage of the battery is 12V and the recommended type of battery is sealed lead acid/SLA/.
As you know it is advisable 12V SLA deep cycle batteries to be used with solar power systems.
The car/track batteries also known as starter batteries are not very well suited for deep cycle operation.
When used in solar power system they exhibit reduced capacity and at least 5 times lower cycle life.
The provided water proofed polycrystalline solar panel has 20W rated power.
The high efficient light weight polycrystalline solar cells are encapsulated in long lasting aluminium frame with tempered glass with 3.2mm thickness which ensures at least 20 year lifespan.
The panel has the following dimensions (L x W x H)mm: 539 × 351 x 19 and following characteristics:
Short circuit current (Isc): 1.22A
Working current (Iop): 1.11A
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℃
Guarantee of power: 90% within 10 years 80% within 25 years
The 3A 12V/24V PWM charge controller provides overcharge and over discharge protection for the battery.
