1Object-affected harmful factors
If water heating is performed using conventional power supply methods, then hot water can be supplied, but noise is generated during operation and energy efficiency is reduced
Solution Approach 1:
The system preheats water during daytime when solar power is abundant and noise sensitivity is low, storing the heated water in a tank for evening use. This preliminary action during off-peak hours eliminates the need for noisy nighttime heating operations while maintaining energy efficiency through solar utilization.
Solution Approach 2:
The system uses solar panels to generate self-sufficient power for water heating operations, reducing dependence on conventional grid power. This self-service approach using renewable energy simultaneously improves energy efficiency and eliminates noise associated with traditional heating systems.
2Productivity
If solar panels and energy storage systems are interconnected with power management devices, then energy management efficiency is improved, but device complexity increases
Solution Approach 1:
The power management device serves multiple functions: it manages solar panel power generation, controls energy storage battery charging/discharging, regulates water heating operations, and provides user interface capabilities. This multi-functionality consolidates what could be multiple separate devices into one unified system, improving energy management efficiency without proportionally increasing complexity.
Solution Approach 2:
The system merges the solar panel controller, battery management system, water heater controller, and user interface into a single integrated power management device. This consolidation enables efficient energy management across all components while reducing the overall number of separate devices and interconnections required.
