Size a photovoltaic system from site conditions, energy use and installation requirements.
Mostly daytime loads, or do you need stored energy for later? That answer shapes the system.
A grid-tied system without batteries is not a backup supply during an outage.
Backup needs its own design: which circuits, battery size and protection.
AI-generated equipment concepts, not photographs of specified models.
System size, yield and payback are assessed per project; there is no standard figure.
Every part must match electrically and structurally, from module to monitoring.
AI-generated conceptModule model chosen for roof space and usage, installed to the manual for the selected module family.
AI-generated conceptConverts DC to AC. The manufacturer advises confirming each module–inverter pairing rather than assuming compatibility.
AI-generated conceptRacking matched to metal-sheet, concrete or carport roofs, with structure and waterproofing checked.
AI-generated conceptGeneration and equipment status data, so your team can see when output drops.
Manufacturer documents are technical context; models, warranty and utility connection terms are confirmed in each proposal.
Each roof needs different racking, structural review and cable routes.

Foundations, drainage and fencingShade from buildings, trees or rooftop plant reduces output, so it is assessed before layout.
Continuous data shows soiled modules, faults or unusual output early.
Protection devices and earthing are designed by qualified engineers to the project requirements.
Modules come from LONGi; inverters and batteries are chosen to match the modules and your usage plan.
This is DPI design guidance, not a quality or price ranking.
One team from survey, design and supply to installation, testing and after-sales support.
Equipment sourced through authorized channels, with model advice and the manufacturer’s warranty terms.
Roof condition, shading, structure and daytime usage are assessed before sizing.
Modules, inverter, mounting, protection, monitoring and the building connection designed as one.
LONGi modules, with inverters chosen for confirmed compatibility.
Commissioning checks, monitoring access, electrical drawings and equipment records at handover.
A Pathum Thani team providing maintenance and technical support across Thailand.
Separate the energy path from monitoring data and design the connection for the building.
Solar supplies the building first; any surplus is exported or limited, as the site’s grid-connection approval allows.
Scene, timing and power values are an illustrative model, not a yield or savings estimate. Real results depend on system size, orientation, tilt, shading, weather, consumption and the utility’s connection terms.
AI-generated equipment concepts, not photographs of specified models.
Concept only, not an electrical wiring or installation guide. Qualified professionals must review the project design and requirements.
Agree commissioning checks, equipment records, electrical drawings, monitoring access and maintenance guidance before handover.
Equipment details, compatibility and scope must be confirmed for each project.
Is roof area enough to size a system?
No. Consider shading, structure, electricity use and electrical-system constraints together. Actual generation depends on the site and design.
Will LONGi modules work with any inverter?
Confirm the exact models and electrical ratings first. A module brand alone does not establish compatibility of the complete system.
The same six stages on every project, so the system is ready on handover day.
