Our solar system design calculation in Yangon service turns site realities into a safe, build-ready design for both the mounting structure and the PV array. Yangon’s mix of RC slabs, metal decks, and tile roofs—plus monsoon winds, standing water, and aging electrical infrastructure—demands calculations that go beyond generic templates. We begin with a structured survey to capture roof type and condition, available set-backs, parapet heights, prevailing wind exposure, and access constraints. From those inputs we build a model that balances energy yield, safety, waterproofing, and maintainability, so your installation performs year after year without nasty surprises.
Mounting structure design starts with wind uplift and mechanical loading. We calculate rail spans and clamp positions using module clamp-zone data and apply conservative safety factors for Yangon’s storm seasons. On RC slabs, we check concrete condition and propose either chemically anchored stanchions with proper edge distances or a ballast solution sized to resist uplift while respecting roof load limits. For metal decks, we specify compatible fasteners, thermal isolation pads, and a fastening pattern that spreads forces across purlins instead of point-loading thin sheets. Waterproofing is treated as an engineering problem: penetrations get manufacturer-rated flashing kits, sealants compatible with roof membranes, and a drainage path that avoids ponding under rails. Where corrosion is a risk, fasteners and brackets are selected in stainless steel or hot-dip galvanized finishes, and dissimilar-metal contact is managed with isolators to prevent galvanic attack.
Array engineering is guided by data rather than rules of thumb. We map shading across seasons, set row spacing to protect early and late sun hours, and align tilt to the roof’s practical geometry as well as your load profile. String sizing is calculated for the inverter’s MPPT window across Yangon’s temperature range, ensuring cold-morning open-circuit voltage stays below absolute limits while hot-afternoon conditions still deliver current in the tracker’s efficient band. Mixed module batches are handled with cautious grouping to reduce mismatch, and where unavoidable shading persists, we evaluate module-level power electronics only when the gain exceeds the extra complexity. Cables are sized for ampacity and voltage drop with realistic routing lengths; DC runs are kept short, polarity-proofed, and protected in UV-stable conduits, while AC feeders are coordinated with distribution board ratings and discrimination so a fault trips locally rather than silencing the whole array.
Electrical protection and earthing are specified with maintenance in mind. We select surge protection devices on both DC and AC sides matched to expected fault energy and earthing topology, and we define residual-current protection where people and portable loads are involved. The earthing and bonding scheme ties module frames, rails, and metallic services into a low-resistance path, verified by test values that will later appear in commissioning records. Labels, string maps, and isolator placements are planned during design rather than improvised on the roof, which makes future inspections faster and safer.
Documentation is the deliverable you can build from. You receive a single-line diagram, stringing tables, cable schedules, breaker lists, mounting details with rail spans and clamp offsets, a wind-uplift summary with assumptions, and a waterproofing note that your civil team can action. We also include a pre-monsoon maintenance plan outlining torque checks, visual inspections, and a safe cleaning method that avoids scratching anti-reflective coatings. If you intend to add batteries later, we reserve conduits, breaker ways, and wall space for a hybrid inverter so expansion is tidy rather than a retrofit wrestling match.
Compliance and local alignment matter for approvals and insurance. We design to recognized low-voltage and PV good practices while staying mindful of Myanmar’s regulatory environment. For official policy updates and resources, you can consult the Government of Myanmar’s Ministry of Science and Technology portal: https://myanmar.gov.mm/ministry-of-science-and-technology. Using authoritative references keeps your project aligned with evolving expectations without burdening the schedule.
Costing remains transparent throughout. The bill of quantities separates structural hardware, modules, inverter, protections, and balance-of-system so you can compare brands without compromising safety margins or waterproofing quality. During handover, our engineers walk through the design intent on-site, explaining isolation points, access routes, and maintenance intervals. The end result is a coherent package—structure that resists Yangon’s weather, an array that stays in its electrical sweet spot, and documentation that turns installation and inspection days into calm, predictable work.
