Let's put it this way, if configured for 5 degrees of power consumption, a solar power generation system of around 1500W is enough. At present, it is generally recommended to make it a grid-connected power generation system. The cost is around 15,000 euros and the lifespan is around 20 years. The main thing is to regularly clean the surface dust. of the solar panel. It is not recommended to use an off-grid system with a battery. The maintenance cost is high and the battery needs to be replaced regularly, the total cost in 20 years is more than 2 times higher than a grid connected system. same power. It can also be used in winter, but the electricity production in winter is less than in summer
2100 W, or 2 kilowatt hours of electricity per hour. Cell phone charging lights. They are little.
It depends on your usage.
Solar panels are around 100 to 150 W per square meter. To meet your needs, it is estimated that more than 20 square meters will be required. If you want to use it during the day, charge it and use it at night. It is estimated that it will double.
The 12V100ah battery can store approximately 1 kilowatt hour of electricity. If you want to use the electric cooker for 2 hours at night, you will need 5-6 batteries. There is a loss of about 15-40% during large discharge and conversion.
If the inverter is afraid of false markings, it is recommended to use a 5 kW inverter.
Do not consider using electrical appliances outdoors. It is recommended to purchase a complete set of mobile phone chargers and lighting. Simple and inexpensive.
