Namkoo Industrial and Commercial PV Systems

Storage Option: MPPT Charge Controller

Component References for Project Review

 

Storage Option: Gel Battery

Gel batteries are sealed lead-acid storage devices. Size capacity for the required usable energy and operating cycle, and follow the specified charging voltage, current and temperature limits. Provide ventilation and inspection access. Battery storage is a separate design choice and is not required in every grid-connected commercial PV system.

Namkoo Commercial and Industrial PV Planning

 

Project Overview

Plan a Namkoo building PV system around daytime consumption, available roof area and the electrical connection. Confirm whether the project is grid-connected, hybrid or off-grid before selecting inverters and storage. Roof loading, shading, access and protection requirements should be reviewed with the installation design.

Design Priorities

• Array Performance: Choose modules by rated output, tested efficiency and usable installation area. Generation varies with sunlight, temperature and shading; confirm the actual panel model.

• Energy Economics: Estimate self-consumption and operating costs using the site load profile and applicable tariffs. Confirm any export or incentive arrangements locally.

• Site Conditions: Check mounting loads, weather exposure and electrical protection. Storm conditions can reduce solar generation; structural suitability does not guarantee constant power.

• Future Capacity: Plan expansion around roof space, inverter inputs, connection limits and component compatibility. Confirm allowances in the initial design.

• Energy Planning: Estimate annual generation and displaced purchased energy using the project location and measured consumption profile.

• Optional Storage: Specify batteries when backup or energy shifting is required. Confirm usable capacity, charging limits and control integration for the selected system.

   • Intended Use: Specify storage for the actual solar or backup-load requirements.

System Architecture

Grid-Connected PV Considerations

1. Supply Scope: A grid-connected PV system may operate without storage. Confirm whether battery backup and island operation are required before selecting equipment.
2. Surplus Generation: Export depends on local connection approval and equipment settings. Confirm export limits or curtailment requirements for the site.

Project Types

• Commercial Buildings: Match generation to the building load profile, roof area and electrical connection.
• Industrial Facilities: Review daytime demand, process loads and site installation constraints.
• Remote Facilities: Off-grid or backup applications need separate storage and power-conversion sizing.

Enquiry Examples

• Pumping Loads: Provide pump power, starting demand and daily operating schedule for configuration review.
• Building PV Loads: Send the site location, roof layout and consumption data to Namkoo for a project-specific proposal.
