The amount of battery a 100w solar panel can charge depends on the discharge capacity of the battery. A 10 hour charge rate should charge an 80 Ah battery. The maximum charging current of a 2V 100W solar panel is about 9A. The longest effective lighting time in Lhasa per day is about 5.5 hours. For other regions, it is calculated at 4 hours, so it can charge more than 4 hours*9 A = 36 Ah. 40ah. In other words, if the 80 Ah battery discharges more than 40 Ah per day, it may not be fully charged. In addition, the maximum charging current of lead-acid batteries is 0.3c, which is 0.3*80ah=24a. They cannot be charged with higher current for a long time. It must be considered globally. The calculation of the discharge quantity is the discharge current multiplied by the discharge time. For example, if the load is a street light, 12v30w, thenThe maximum working current is about 3A, then the discharge quantity will be 30Ah after working about 10 hours per night.
What size battery can a 100W solar panel have?
Solar panels produce DC power and televisions require AC power. Therefore, solar panels cannot directly power the TV. An inverter is required for the conversion, which depends on the power of the device.
If the power of the solar panel is 100W and the power of the inverter is also 100W, then it can power a TV with around 70W. Check the power of your TV to know if 'it can be piloted.
This question is too difficult to ask.
100W is only the theoretical output power of the solar panel. If you want to fully charge it in 8 hours, then the theoretical capacity is 100W*8h=800wh=0.8 kWh=0,8 degrees
And the general battery label. The scale unit is AH, and the batteries are basically 12V,
800wh/12v≈67AH
The common battery capacities are 40, 60, 80. , 100, 120 and 160AH, which means 80AH. It can meet the storage needs of 8 hours of energy from a 100W solar panel.
The larger the capacity of the battery, the more energy it can store. Of course, it is also more expensive, so consider it appropriate.
In addition, the self-discharge of larger batteries is relatively greater, so you should pay attention to it.
