The main criteria for choosing solar panels
Power. This characteristic has a direct impact not only on the efficiency of the device, but also its cost. Naturally, the more powerful the solar battery, the greater the amount will have to pay for it.

Of course, in the second case, you need to pay a lot more for the solar battery.
