Designing and installing a total of a total 10kW solar electric system comprising the following:

• 5kW, 48VDC Bus voltage inverter, 8x 330W Monocrystalline Panels, and a 48V, 200Ah Deep Cycle Battery
• 2.5KW, 24V DC Bus voltage Inverter, 4x330W Monocrystalline Panel, 220AH, 24V Deep Cycle Battery
• 2.5KW, 24V DC Bus voltage Inverter, 2x330W Monocrystalline Panel, 200AH, 24V Deep Cycle Battery

1. Site Assessment:

• Project began by conducting a thorough assessment of the installation site to determine the available solar resource, shading, and roof or ground space for panel placement.

2. Load Assessment:

• Calculate the daily energy consumption of the property to size the system accordingly.

3. System Sizing:

• components were selected based on the system sizes and energy requirements.
• Calculation of the total capacity of the solar panels to meet energy demand.

4. Solar Panel Selection:

• high-efficiency 330W monocrystalline solar panels were chosen
• Determination of the optimum panel placement, azumith angle, and orientation for maximum sun exposure.

5. Inverter Selection:

• Selection of inverter compatible with the system voltage and capacity.

6. Battery Bank:

• Installation battery bank to store excess energy for later use.
• Ensured proper battery placement in a well-ventilated and secure location.

7. Mounting and Racking:

• Designed and install a sturdy mounting system for all solar panels on the rooftop.
• Optimized panel angle and orientation for maximum solar exposure.

8. Wiring and Connection:

• Wired the solar panels in series or parallel to match the inverter’s input voltage requirements.
• Connect the panels to the inverter, ensuring proper grounding and overcurrent protection.

9. Inverter and Battery Installation:

• Mounted the inverter and battery system following the manufacturer’s guidelines.
• Ensured safe and secure installation.

10. Electrical Connections: – Connect the inverter to the electrical distribution panel to feed electricity into the building. – Install necessary wiring, disconnects, and circuit breakers.

11. Monitoring and Control: – Set up a monitoring system to track the performance of the solar electric system, including battery charge status and power production.

12. Testing and Commissioning: – Tested the entire system to ensure it generates electricity as expected and effectively charges the batteries. – Verify that the inverter operates efficiently and manages the battery system.

13. Safety and Compliance: – Ensured all electrical work complies with local building codes and safety standards. – Checked that the system is properly grounded and protected from electrical hazards.

14. Maintenance and Monitoring: – Implemented a regular maintenance schedule to clean panels, inspect wiring, and monitor battery health. – Continuously monitored the system for performance issues or anomalies.

Designing and installing a solar electric system with a battery bank is a significant project that should be carried out by experienced professionals to ensure safety and efficiency. It’s important to adhere to safety and code requirements, as well as to monitor the system’s performance over time.
