Our rooftop and ground solar PV installation in Mandalay service is engineered for the region’s hot seasons, dust, and monsoon winds. We deliver full-scope projects for homes, hotels, clinics, schools, farms, and light industry across Chanayethazan, Amarapura, Pyin Oo Lwin, Meiktila, and Myingyan. From the first survey to final handover, the goal is reliable energy and clean workmanship: a system that performs on day one and remains easy to operate and maintain for years.
Every project begins with a site survey that captures the realities of your property rather than relying on brochure assumptions. We document roof orientation and tilt, year-round shading, truss or slab condition, waterproofing status, and safe access for installation and maintenance. For ground-mounts, we examine soil and drainage, wind exposure, fencing, and equipment access so foundations, cable trenches, and clearances are defined early. Your tariff and load profile shape system size and architecture: grid-tied to cut daytime bills, or hybrid where evening backup is essential. We share a simple single-line diagram so owners, caretakers, and inspectors can follow the plan without guesswork.
Design turns survey data into durable decisions. Mounting layouts set rail spans and clamp positions within each module’s approved zones, with hardware chosen to handle Mandalay’s heat and dust. On RC slabs, we specify chemically anchored stanchions or ballast frames with edge distances and membrane compatibility in mind. Metal decks receive roof-specific fasteners, isolation pads to prevent galvanic reactions, and a fastening pattern that spreads forces across purlins. Waterproofing is detailed, not improvised, using manufacturer-rated flashing and sealants with known compatibility. Array geometry preserves drainage so water cannot pond beneath rails, and walkways are kept for safe cleaning and service.
Electrical engineering keeps the PV array inside its sweet spot across Mandalay’s temperature range. We map strings for each inverter’s MPPT window so cold-morning open-circuit voltages stay within limits and hot-afternoon currents are still efficient. Cable sizes are calculated for ampacity and voltage drop based on actual route lengths, with UV-stable conduits and mechanically protected pass-throughs. On the AC side, feeders, breakers, and discrimination are coordinated so a fault trips locally instead of silencing the entire plant. Surge protection is specified on both DC and AC sides, residual-current devices protect people and portable loads, and the earthing and bonding scheme ties frames, rails, and metallic services into a low-resistance path verified later during commissioning.
Installation quality determines how quietly a system lives. Our teams work to documented method statements, lock-out/tag-out procedures, and working-at-height controls. Rails are aligned so rows shed water cleanly; penetrations are sealed with compatible flashing; DC wiring is clipped, polarity-checked, and strain-relieved before it ever sees sunlight. Inverters are mounted with ventilation clearance and away from damp or dusty hotspots, communication gateways are positioned for stable monitoring, and all isolation points are labeled clearly so non-technical staff can operate them safely.
Commissioning is a recorded process rather than a quick switch-on. We measure open-circuit and short-circuit values per string, verify insulation resistance and polarity on both DC and AC sides, confirm earth continuity, and check surge protection indicators. Inverter country codes, grid profiles, and export limits are set correctly; for hybrids, charge windows and backup priorities are tuned to your tariff and outage pattern. We run live tests that include simulated grid loss to confirm the essential-loads sub-board keeps refrigeration, networking, lighting, and point-of-sale equipment running while non-essentials remain on utility.
Handover includes what you need to operate and pass inspections with confidence: the single-line diagram, string maps, cable schedules, breaker lists, test sheets, warranty cards, and an upkeep plan covering safe cleaning intervals, torque checks, and a pre-monsoon thermal scan. Clear labeling from rooftop isolators to distribution boards shortens future troubleshooting and improves safety during maintenance. Because domestic guidance evolves, we align designs with recognized low-voltage and PV good practice and keep an eye on local policy.

Financially, we aim for realistic returns rather than optimistic charts. Daytime-heavy users—offices, hospitality, schools—maximize savings with grid-tied PV and smart load scheduling during solar hours. Sites that suffer evening outages benefit from hybrid systems sized around essential circuits instead of whole-building backups. Proposals compare trusted brands across budget tiers without compromising protection, earthing, or waterproofing, and we reserve space in boards and conduits so adding batteries or extra modules later is an upgrade, not a demolition. The result is a quiet, productive solar asset built for Mandalay’s climate and your operating reality.
