How to Use the PV System Storage Size Calculator

Purpose:
This calculator is designed to help users determine the optimal size for energy storage units (such as Lithium-ion Capacitors - LiC, and Lithium-ion Batteries - LiB) in off-grid photovoltaic (PV) systems. It takes into account various factors including PV generation capacity, average load, days of autonomy, and system lifetime under different scenarios.

Instructions:

1. Enter Your Data: Fill in the fields for:

• Average load (in Wh/day)
• Required days of autonomy
• Years of system lifetime

1. Choose a Scenario: Select from the available scenarios - 'Dynamic Load & Temperature', 'Constant Temperature 25°C', and 'Constant Load'. These scenarios represent different operational conditions.
2. 
   
3. Select Storage Type: Choose between Lithium-ion Capacitors (LiC) and Lithium-ion Batteries (LiB).
4. 
   
5. Calculate: Click on the 'Calculate' button to get the recommended storage size.

Understanding the Results:
The calculator will display the size of the energy storage system in ampere-hours (Ah). This size is optimized based on your inputs and the chosen scenario, ensuring efficient and reliable energy storage for your off-grid PV system.
