Not - whether the amorphous panel or single crystal. If the spec says 40W, then the output power is 40W equal. Only the panel size of the amorphous Must be built to be larger than a single crystal panel To achieve the same output power
Single crystal panel provides efficiency The conversion of solar energy into electricity per unit of light-receiving area is the best, followed by combined crystals. And finally, amorphous
Every panel can be used in the same way. Only in the work that requires little installation space, lightweight, should use single-crystal panel or combined crystal
In general, at equal watts. The cheapest amorphous panel Higher is the total crystal. And single crystal
There are 3 types of solar panels:
- Amorphous type (the panel is like a film coated on a brown glass), for example, the solar panel on the calculator
- single-crystal type The panel will look like a black panel with solar cell panels. To be homogeneous
- The combined crystalline panel has a blue color, the solar cell material is the characteristic of the crystal Many styles combined
40W (watts) is the electrical power value for a solar cell panel. 40W means if we set up a panel A 40W solar cell will receive 1 hour of sunlight and will produce 40 W of electricity. If you receive 2 hours of sunlight, it will produce electricity = 40x2 = 80 watts, so if you set the light at 8 hours during the day will generate electricity = 40x8 = 320 watts
The solar cell panel can be used to charge the battery like AA or AAA size batteries, Nicd or NiMh, Lion + batteries, lead acid batteries
The solar cell panel can be used to charge a 12V or 24V car battery.
It can be done, but the efficiency is not as good as charging through the battery charger and there is no stopping charging when the battery is refilled. We have to remove the solar panels by ourselves when Full battery
Increasing the electric power of solar panels Achieved by bringing the solar cell panels connected in parallel (the anode of all solar cells connected together , The negative pole of all the panels are connected together) such as having a 40W panel to increase the total electric power = 120 watts. Therefore, 3 panels of 40 watts must be connected in parallel. We will get the total electricity produced = 40x3 = 120 watts.
