Solar Battery Size Calculation Explanation

Based on the principle of energy conversion, the formula is as follows:

$$AH = \frac{Daily\ Solar\ Irradiance \times Solar\ Panel\ Area \times Solar\ Panel\ Efficiency \times 1000}{Battery\ Voltage}$$

• AH – Amp-Hours (Ah)
• Daily Solar Irradiance – The amount of solar energy received per square meter per day (kWh/m²)
• Solar Panel Area – The total surface area of the solar panels in square meters (m²)
• Solar Panel Efficiency – Efficiency percentage of the solar panel in converting solar energy to electrical energy
• Battery Voltage – The voltage rating of the battery (12V, 24V, or 48V)

What is Solar Energy?

Solar energy is the energy harnessed from the sun's radiation. Solar panels convert sunlight into electricity, which can be used to power various devices.

What is Solar Panel Efficiency?

Solar panel efficiency refers to the percentage of sunlight that can be converted into usable electricity by a solar panel. The higher the efficiency, the more power the panel can generate from the same amount of sunlight.

What is the Role of Battery Voltage?

Battery voltage refers to the electrical potential difference across the battery's terminals. Higher voltage batteries are often used in systems where higher capacity and longer power durations are required.

What is the Purpose of the Solar Battery?

The solar battery stores excess energy produced by solar panels during the day for use during the night or in periods of low sunlight. This allows for uninterrupted power supply even when the solar panels are not actively producing electricity.
