I. Design Phase

Site Survey

Load-bearing capacity: It is necessary to determine the load-bearing capacity of the roof or floor, obtain architectural structural drawings, and have a structural load report issued by a professional institution.

Power Consumption Analysis: Collect historical electricity usage data, consumption patterns, and peak loads from the factory.

Shadow analysis: Observe the surrounding environment and avoid obstructions caused by chimneys, parapets, air conditioner outdoor units, and trees.

local weather: Collects local weather data for the entire year. For example: annual sunshine hours, total solar radiation.

System Design

Equipment selection: When choosing high-performance solar panels and inverters, attention should be paid to the capacity ratio between the equipment.

Support structure design: Ensures the corrosion resistance (especially in coastal areas) and pressure resistance of outdoor photovoltaic power stations.

Electrical design: Design grounding and lightning protection systems, and provide DC arc protection where necessary to prevent fires.

II. Installation Phase

Construction safety

Personnel safety: Protective equipment must be worn when entering the construction area.

Electrical safety: Check in advance whether the equipment is powered off.

Equipment Installation

Mounting Structure: Ensure flatness and levelness to prevent micro-cracks in modules.

Support structure design: Ensures the corrosion resistance (especially in coastal areas) and pressure resistance of outdoor solar farms.

Electrical design: Design grounding and lightning protection systems, and provide DC arc protection where necessary to prevent fires.

Electrical Wiring

MC4 interface: Ensure that all interfaces are securely connected and well-sealed.

Wiring standards: Cables should be fixed neatly, and different lines should be laid separately.

Reliable grounding: All non-energized metal parts must be effectively grounded.

III.Operation & Maintenance Phase

Regular Inspections

Daily monitoring: View power generation data daily through the monitoring system.

Regular inspections: Perform visual inspections and regular cleaning of the solar panels.

Electrical inspection: Use a thermal imager to scan combiner boxes, inverters, and other equipment to promptly identify any abnormal overheating in the power generation system.

Common Faults

Inverter failures: Common causes include abnormal grid voltage and low insulation impedance.

Low power generation: Common causes include continuous rainy weather, module obstruction, failure of a module in the string, and inverter failure.
