Do you wonder about the wattage of solar lamps? Why do some companies claim that their solar lamps are 1000 watts, but there is such a big gap between them and the real 1000 Watt lamps?
Before I explain the reason, you need to understand what wattage means to a lamp.Power is a physical quantity that describes the work capacity of a light bulb. It is usually expressed by the work done by the light bulb per unit time. The unit is Wattagr, or W for short.
According to this, you can see that it is difficult to calculate the wattage of solar lamps.Because the working principle of the solar lamp is to store the electric energy converted by the photovoltaic panel in the time of effective light charging into the battery of the lamp, and then release the electric energy to light the lamp at night.
Therefore, here is a formula:
Battery(ah)× battery(V)÷ Work days(full charged) ÷ Work hours(daily)÷ Efficacy(Usually 20%)=
Based on this, for example, the following picture:
1. 6.4V*3AH/2DAYS/8Hours/0.2= 8Watt
2. 6.4V*12AH/2DAYS/8HOURS/0.2= 24Watt
This is totally common but not right in the market to dummy data. Wosen has been specialized in LED manufacturing since 1992, and offered lighitng solutions about 10 years. 300workers, 30,000 square meters, ISO9001 2015, CE, DLC and so on.
