Our solar PV upgrade and modification service in Shan State extends the life and boosts the performance of systems installed years ago across Taunggyi, Kalaw, Nyaungshwe (Inle Lake), Kengtung, and Lashio. If your array was sized for older tariffs, fitted with a basic inverter, or is suffering from nuisance trips and poor yields, we re-engineer the system so it matches today’s loads, safety expectations, and grid behavior. Instead of ripping everything out, we diagnose what can be reused—modules, rails, cabling—and what should be refreshed to deliver safer, steadier kilowatt-hours.
The process starts with measurement, not guesswork. We test open-circuit and short-circuit values per string, compare them to plate ratings and expected irradiance, and isolate underperforming modules. Thermal imaging and IV-curve checks reveal cracked cells, diode issues, or hotspots that sap output. We also inspect connectors, combiner boxes, and DC isolators for heat marks, mismatches, or water ingress—common root causes of intermittent faults on older rooftops. On the AC side, we log voltage and frequency stability, review breaker sizing, and check earthing continuity so that any inverter upgrade is paired with proper protection and clean utility interconnection.
Re-stringing is often the single biggest win. Early systems were strung to chase peak voltage but ignored seasonal temperature swings—leaving inverters outside their happy MPPT window for much of the day. We redesign strings to keep each tracker in its efficient range, reduce mismatch, and protect against over-voltage on cold mornings in highland Shan. Where shading or module mismatch is unavoidable, we consider optimizers only where they offer a measurable gain rather than adding complexity everywhere. Cabling is recalculated for ampacity and voltage drop; aging MC4 connectors are replaced with crimped, torque-verified terminations; and UV-brittled conduits give way to fresh, weather-resistant runs.
Inverter updates are the heart of many retrofits. Modern units offer wider MPPT windows, better surge tolerance, and grid-support features that reduce nuisance trips. If your property experiences frequent outages, we design a hybrid path: a right-sized hybrid inverter and an LFP (lithium iron phosphate) battery that covers essentials such as networking, refrigeration, lighting, or point-of-sale. Critical circuits are moved to an essential-loads sub-board, keeping heavy non-essentials on utility so backup hours stretch longer. For sites that stay grid-tied, we prioritize self-consumption and set export limits if required by local utility practice.
Safety upgrades turn an old system into a dependable asset. We add or replace surge protection devices on both DC and AC sides, specify residual-current protection where appropriate, and validate earthing and bonding with measured resistance values. Combiner boxes are re-gasketed or replaced, labels are standardized from roof to distribution board, and isolation points are positioned where maintenance staff can operate them without confusion. Where roof hardware shows corrosion, we swap in stainless or hot-dip-galvanized fasteners and restore flashing and sealants so waterproofing is as robust as the electrics.
Documentation is what makes the upgrade auditable and maintainable. You receive an updated single-line diagram, as-built drawings, test sheets (insulation resistance, polarity, earth continuity, RCD and SPD checks), and a maintenance plan with cleaning intervals, torque checks, and a suggested pre-monsoon thermal scan. Monitoring is connected or restored so you can track generation, consumption, and state-of-charge from a simple dashboard. These records help with landlord approvals, insurance, and future troubleshooting—and they keep the system performing, not just “on.”
Because rules and expectations evolve, we align our work with recognized low-voltage and PV good practice while following domestic guidance. For official updates and policy resources relevant to engineering in Myanmar, consult the Government’s Ministry of Science and Technology portal: https://myanmar.gov.mm/ministry-of-science-and-technology. Grounding methods, protection choices, and documentation standards benefit from anchoring to authoritative sources, which reduces approval friction and keeps safety at the forefront.
Financially, the aim is pragmatic improvement rather than shiny overspend. Daytime-heavy users in hospitality and schools often benefit most from better stringing and a modern inverter; clinics, retail, and homes that face evening outages gain from modest battery capacity targeted at essentials. We present tiered options that reuse what’s sound, replace what’s risky, and leave room for future expansion—spare ways in boards, clean conduits, and monitoring points. The outcome is a quieter, safer, more productive PV system tailored to Shan State’s climate and your actual operating reality.
