In theory, 1 square meter of solar panels can generate 1.2 to 1.4 kWh of electricity in 10 hours.
Generally speaking, 1 square meter of crystalline silicon solar panel is equivalent to about 120-140 W. If calculated as 120 W, the sun at 6 hours a day is 120*6 = 720 WH.
For a 10W lamp, it depends on the number of hours of use per day and the number of consecutive rainy days it requires. If it is used 9 hours a day and 3 rainy days, then the battery panel. should be 30-50W.
Scopes of application

IV. Oil, marine and meteorological fields
oil pipelines and solar energy systemsire of cathodic protection of tank doors, service life of oil drilling platforms and emergency power supplies, marine detection equipment, meteorological/hydrological observation equipment awaits.
To answer this question we need to consider the following aspects:
First of all, we need to know how much electricity a 60 square meter solar panel can generate. This value depends on the type and quality of the panels. Generally speaking, each square meter of panels can produce around 200 to 400 watt hours of electricity per day.
Assuming that each square meter of panel produces 300 watt hours of electricity per day, then 60 square meters of panel can produce 18,000 watt hours of electricity per day.
Next, you need to consider the price of solar panels. Prices vary depending on market conditions and the type and quality of panels.
In additionAssuming that electricity production costs 10 yuan per watt hour, the total daily investment in 60 square meters of solar panels would be 18,000 watt hours × 10 yuan/watt hour = 180,000 yuan.
Finally, energy storage and export costs must be taken into account. These costs depend on the type and quality of panels and storage equipment, as well as electricity market prices.
Assuming that the cost of energy storage and generation is 5 yuan per watt hour, the total daily investment of 60 square meters of solar panels should be added to this part of the cost.Cost : 18,000 watt hours × 5 yuan/watt hour = 90,000 yuan.
Therefore, the total investment for solar power generation on 60 square meters requires about 270,000 yuan.
As for the amount of electricity that can be produced each day, this value will vary due to many factors, including the cweather conditions, orientation and tilt angle of the battery panels, etc. Generally speaking, a 60 square meter solar panel can produce around 1,800 to 3,600 watt hours of electricity per day.
Assuming that an average of 2,700 watt hours of electricity can be produced per day, a 60 square meter solar panel can produce approximately 27 kilowatt hours of electricity per day.
It should be noted that this value is only a rough estimate and the actual situation may be different.
