Kia pehea te roa ki te utu i te pākahiko porohita hohonu ma te whakamahi i nga panui solar?

The time it takes to charge a deep cycle battery using solar panels depends on several factors, including the āheinga pūhiko, te solar panel wattage, te sunlight conditions, Me te ahua utu Tuhinga o mua.

Battery Capacity (Ah or kWh)

The capacity of your deep cycle battery is usually expressed in amp-hours (Ah) or kilowatt-hours (kWh). A typical deep cycle battery might range from 100 Ah to 300 Ah or more.

Hei tauira:

  • A 12V battery with a 100 Ah capacity stores 1,200 watt-hours (Wh) of energy (12V * 100Ah = 1,200Wh).

Solar Panel Output (W)

The size of your solar panel system also impacts how quickly you can charge your battery. Solar panels are rated by their wattage (W), and the total output depends on the amount of sunlight they receive.

Hei tauira:

  • A 300W solar panel under full sunlight can produce 300 watts per hour, though this can vary depending on geographic location and weather conditions.

Nga Tikanga Ra

Solar panel output is directly related to the amount of sunlight available. On a bright sunny day, you might get around 5-6 hours of peak sun, but on cloudy days, this could drop to 2-3 hours or less.

Te Mana Whakahaere (SOC)

The time required to charge the battery also depends on how much energy is already stored in the battery. If the battery is discharged to 50% capacity, you'll need less time to recharge it compared to when it's fully discharged.

Formula to Estimate Charging Time:

You can estimate the charging time using the following formula:

Charging Time (hours) = Battery Capacity (Wh) ÷ [Solar Panel Output (W)×Sunlight Hours]

Tauira Tauira:

  1. For a 100Ah, 12V Battery and a 300W Solar Panel:

    • If you have 5 hours of full sunlight, the solar panel will produce about 1,500Wh of power (300W * 5 hours).
    • To fully charge a 12V, 100Ah battery (1,200Wh), it could take approximately 1-2 ra of full sunlight depending on other factors like system efficiency.
  2. For a 200Ah, 12V Battery:

    • A 200Ah battery stores 2,400Wh (12V * 200Ah).
    • With the same 300W solar panel and 5 hours of peak sun, the system could take 2-3 ra to fully charge the battery in optimal conditions.
