Approximately 3 degrees.
The power consumption of the solar water heater display is very low, approximately 5 watts per hour. Power consumption per day is 5 × 24 = 120 watts, or approximately 0.1 kilowatt hours per hour. day, that is, solar energy is said to consume approximately 3 kilowatt hours of electricity only for 30 days per month.
The amount of electricity a solar panel of this power can generate is:
The amount of electricity generated by a solar panel of 100 watts in a day depends on many factors including geographic location, weather conditions, installation angle and direction, etc. Under ideal conditions, such as on a sunny day, a 100 watt solar panel will provide approximately 4 hours of effective sunlight per day.
If we consider that the efficiency of the system is approximately 70%, the production ofEnergy production of the grid-connected system is approximately 0.3 kilowatt-hour, while energy production of the off-grid system is approximately 0.2 kilowatt-hour. hours.
