LOAD ANALYSIS

The key to reliable operation, enhanced performance, safety, and longevity of solar systems lies in precise system design and accurate sizing of each component. For off-grid solar systems, the sizing process includes several critical steps:

1. Electric Load Estimation
2. Inverter Sizing and Specification
3. Battery Sizing and Specification
4. Array Sizing and Specification
5. Controller Specification

Electric load estimation involves listing all appliances, their power ratings, and operation hours, then summing these to obtain the total average energy demand in watt-hours (Wh) or kilowatt-hours (kWh). This total average energy demand is essential for determining the appropriate size of the inverter.

It is crucial to conduct a thorough load analysis before proceeding with other steps, preferably with someone who is well-versed in this process.
