Solar power basics

How sunlight becomes usable electricity

1

Sunlight reaches the module

PV cells convert light into direct-current electricity. Rated watts are measured under standard test conditions; real output changes with irradiance, temperature, shade and dirt.

2

MPPT captures available power

The inverter continuously adjusts PV voltage and current to operate near the array's maximum power point.

3

The inverter supplies AC power

DC becomes synchronized AC for appliances, motors and distribution boards. A hybrid inverter can also charge a battery and coordinate the grid or generator.

4

Energy is used, stored or exported

Loads normally use solar first. Surplus may charge the battery or export where permitted; shortages come from the battery, grid or generator according to control settings.

Basic production estimateDaily energy ≈ array kWp × peak-sun-hours × performance ratio
5.5 kWp × 5.0 h × 0.78 ≈ 21.5 kWh/dayIllustrative clear-season day; monthly weather changes the result.

Battery ranges are examples for critical-load backup, not fixed bills of materials. An energy audit must separate essential loads from air-conditioning, water heating, pumps and industrial motors.

Technology selection

Match module size to the structure

400–500 W

Residential roof class

Easier handling, flexible roof layouts and broad compatibility with residential inverters.

540–650 W

Commercial roof class

Fewer modules and connections per kWp, but larger dimensions and higher string current require careful engineering.

700–800 W

Large-format engineered class

Best considered for ground mounts or engineered large roofs. Verify commercial availability, dimensions, wind loading, clamp zones and inverter current limits.

Recommended modern baseline

  • N-type TOPCon or HJT modules with IEC 61215 and IEC 61730 certification
  • MPPT hybrid or grid inverter with local service support and documented battery compatibility
  • LiFePO₄ storage with cell monitoring, BMS, DC isolation and IEC 62619 evidence
  • Remote monitoring, generator integration and export limiting where required

Connection reference

Accessories, wiring and grounding guide

Cable size is determined from current, voltage, installation method, ambient temperature, grouping, voltage drop and fault withstand—not from system kW alone.

Battery-first design

LiFePO₄ first; flooded battery only where justified

Battery energy (kWh), battery power (kW), inverter voltage and the BMS protocol must all match. Brand name alone does not prove compatibility.

SPECIAL CASE

Flooded deep-cycle lead-acid

  • Lower initial cost can suit basic off-grid or essential-load systems
  • Requires ventilation, upright acid-resistant containment and safe service access
  • Needs electrolyte-level checks, correct charging and corrosion control; never install in living or escape areas

Balance of system

DC, AC, earthing and protection accessories

Protection devices must be selected from voltage, current, fault level, earthing arrangement and cable calculations—not copied from a generic bill of materials.

DC side

PV1-F cable, compatible connectors, gPV fuses where required, string combiner, DC-rated isolator, Type 2 SPD, battery fuse or DC breaker, labels and cable containment.

AC side

Correctly rated MCB/MCCB, lockable AC isolator, Type 2 SPD, RCD/RCBO only where the inverter and earthing arrangement permit, ATS/changeover where required, metering and an essential-load board.

Earthing and lightning

Bond module frames, rails and equipment; verify earth continuity and resistance. Coordinate SPDs with the lightning-protection system and use Type 1+2 protection where the risk assessment or incoming supply requires it.

Representative manufacturers to evaluate include ABB, Schneider Electric, CHINT, DEHN and Phoenix Contact. Select only model-specific DC/AC ratings and request coordination evidence; this is not an endorsement or stock confirmation.

Monthly solar resource

Myanmar solar radiation and availability map

Select a month to compare long-term average daily global horizontal irradiation (GHI) at 17 representative locations. The map shows Myanmar's 14 state and region boundaries.

3.56.7 kWh/m²/day
Selected monthApril
17-location range5.27–6.65kWh/m²/day
Myanmar pattern

February–April is generally strongest. Monsoon cloud lowers GHI most noticeably from June–August, especially in coastal and southern areas; central Myanmar remains comparatively stronger.

Monthly GHI matrix — kWh/m²/day

Solar source: NASA POWER long-term climatology, ALLSKY_SFC_SW_DWN. Annual total is calculated as each monthly average daily GHI multiplied by the number of days in that month and summed for a 365-day year. Magway and Chauk share the same NASA climatology grid cell.
