Answer:
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
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
In general, at equal watts. The cheapest amorphous panel Higher is the total crystal. And single crystal
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
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
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
