The MPPT Calculator is a simple, user-friendly tool designed to help you size and optimise your solar panel system by calculating the key specifications for an MPPT (Maximum Power Point Tracking) controller. It takes into account your solar panel details, system configuration, and environmental factors to ensure your solar setup runs efficiently and safely.

How It Works

1. Solar Panel Details
   The calculator starts by asking for details about your solar panels, such as:
   • Panel Voltage (Voc): The maximum voltage a panel can produce when not connected to a load.
   • Short Circuit Current (Isc): The maximum current a panel can deliver.
   • Panel Wattage (W): The power rating of a single solar panel under standard conditions.
2. System Configuration
   Next, it considers how your solar panels and battery system are configured:
   • Battery Voltage: Choose the battery voltage (e.g., 12V, 24V, 36V, 48V) for your system.
   • Number of Panels in Series: Determines the total voltage by adding up the voltage of each panel in the series.
   • Number of Panels in Parallel: Determines the total current by summing up the currents of each parallel panel.
3. Environmental Factors
   The calculator also considers real-world conditions:
   • Minimum Temperature: Adjusts for voltage changes that occur in cold weather. Solar panels produce higher voltage in colder temperatures, and this adjustment ensures your MPPT controller can handle the increased voltage.

What It Calculates

The APPT Calculator provides:

• Adjusted Panel Voltage (Voc): Adjusted for temperature variations using a correction factor.
• Total Voltage (Voc Total): Based on the number of panels in series.
• Total Current (Isc Total): Based on the number of panels in parallel.
• Total Power: Calculates the combined wattage of all your panels.
• Recommended MPPT Values:
  • The voltage range your MPPT controller should support.
  • The current capacity your MPPT controller needs to handle.

Who Should Use This Calculator?

The APPT Calculator is ideal for:

• Solar enthusiasts looking to size their MPPT controller.
• Homeowners designing a solar panel system for their energy needs.
• Installers and professionals ensuring their solar setups are efficient and safe.
