Our solar system design calculation in Bago service turns site realities into a safe, build-ready plan for both the mounting structure and the PV array. Bago Region mixes RC slab roofs, metal decks, and tiled surfaces with monsoon winds, occasional flooding, and long sun hours. Templates and guesswork fail under those conditions. We start with a structured survey that captures roof type and condition, parapet heights, usable setbacks, prevailing wind exposure, drainage paths, and access for installation and maintenance. From these inputs we produce calculations and drawings that balance energy yield, mechanical safety, waterproofing, and maintainability so your investment performs predictably year after year.
Mounting structure design begins with wind uplift and mechanical loads. We compute rail spans and clamp positions based on module clamp-zone data and apply conservative safety factors suited to Bago’s storm seasons. On RC slabs, we evaluate concrete strength, edge distances, and membrane condition to choose between chemically anchored stanchions or ballast frames. For metal decks common in industrial estates, we specify compatible fasteners, thermal isolation pads, and a fastening pattern that spreads forces across purlins rather than point-loading thin sheet. Waterproofing is engineered, not improvised: every penetration gets manufacturer-rated flashing and sealants that are chemically compatible with the roof system, and array geometry preserves drainage so water cannot pond beneath rails or around footings.
Corrosion control is treated as a first-order constraint, not a footnote. We select stainless or hot-dip galvanized hardware where exposure demands it, manage dissimilar-metal contact with isolators to prevent galvanic reaction, and route cable in UV-stable conduits with clips that do not abrade insulation. Where the site is near agricultural dust or light industrial emissions, we account for accelerated wear by specifying cleaning corridors, safe tie-off points, and protective grommets at every pass-through. These details reduce creaks, leaks, and maintenance calls over the system’s life.
PV array engineering is driven by measured data. We map seasonal shading from trees, parapets, and nearby structures, then set tilt and row spacing to protect early and late sun hours without inviting wind problems. String sizing is calculated for the inverter’s MPPT (maximum power point tracking) windows across Bago’s realistic temperature range, ensuring that cold-morning open-circuit voltage remains below absolute limits while hot afternoons stay within efficient current bands. Mixed module batches are grouped to minimize mismatch, and where partial shading is unavoidable, we evaluate module-level power electronics only when the gain exceeds added cost and complexity. DC cable sizes are set for ampacity and voltage drop using route-lengths from the actual layout; terminations are specified with torque values and polarity checks baked into the commissioning plan. On the AC side, feeder sizing and protective devices are coordinated with your distribution board so a fault trips locally rather than silencing the entire array.
Protection, earthing, and labeling are designed into the system rather than added at the end. Surge protection devices are specified on both DC and AC sides to match expected exposure and earthing topology. Residual-current protection is applied where people and portable loads are involved, and equipotential bonding ties module frames, rails, and metallic services into a low-resistance path. We plan isolation points where technicians can operate safely and we standardize labels, string maps, and equipment IDs from roof to distribution board so future inspections and maintenance are quick and unambiguous.
Documentation is your build kit. You receive a single-line diagram, string tables, cable schedules, breaker lists, mounting details with rail spans and clamp offsets, a wind-uplift summary with assumptions and safety factors, and a waterproofing note that your civil team can action. We include a pre-monsoon maintenance plan that outlines safe cleaning methods, torque checks, visual inspections for gasket wear, and a recommended thermal scan to catch hot connections before they become failures. If you plan to add batteries later, we reserve wall space, conduits, and breaker ways for a hybrid inverter so expansion is neat rather than a retrofit wrestling match.
Compliance and local alignment matter for approvals, insurance, and long-term safety. We follow recognized low-voltage and PV good practice while tracking domestic guidance from the Government of Myanmar.

Using authoritative references keeps your project aligned with evolving expectations without slowing the schedule.
Costing remains transparent. 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 integrity. During handover, our engineers walk through the design intent on-site, explaining isolation points, access routes, and maintenance intervals. The outcome is a coherent package—structure that resists Bago’s weather, an array that lives inside its electrical sweet spot, and documentation that turns installation and inspection days into calm, predictable work.
