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.

Solar power basics
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.
The inverter continuously adjusts PV voltage and current to operate near the array's maximum power point.
DC becomes synchronized AC for appliances, motors and distribution boards. A hybrid inverter can also charge a battery and coordinate the grid or generator.
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.
Reference configurations
| Use case | PV | Example modules | Inverter | Battery planning range | Electrical form |
|---|---|---|---|---|---|
| Essential home | 3.3 kWp | 6 × 550 W | 3–5 kW hybrid | 5–10 kWh | Single phase |
| Standard home | 5.5 kWp | 10 × 550 W | 5–6 kW hybrid | 10–15 kWh | Single phase |
| Large home or shop | 10.8 kWp | 18 × 600 W | 10 kW hybrid | 15–30 kWh | Single or three phase |
| Small business | 20.4 kWp | 34 × 600 W | 20 kW three phase | 30–60 kWh | Three phase preferred |
| Commercial facility | 50.4 kWp | 84 × 600 W | 50 kW three phase | 80–150 kWh | Three phase |
| Medium C&I | 100.8 kWp | 168 × 600 W | 100 kW or 2 × 50 kW | 160–300 kWh | Three phase with protection study |
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
Easier handling, flexible roof layouts and broad compatibility with residential inverters.
Fewer modules and connections per kWp, but larger dimensions and higher string current require careful engineering.
Best considered for ground mounts or engineered large roofs. Verify commercial availability, dimensions, wind loading, clamp zones and inverter current limits.
Connection reference
Cable size is determined from current, voltage, installation method, ambient temperature, grouping, voltage drop and fault withstand—not from system kW alone.
| Circuit | Cable / connection | Accessories | Installation rule |
|---|---|---|---|
| PV string DC | H1Z2Z2-K / PV1-F copper solar cable | Matched PV connectors, UV clips, conduit/tray, labels | Keep +/− together, avoid roof contact and sharp bends; never mix connector brands. |
| Battery DC | Manufacturer harness or flexible fine-strand copper battery cable | Crimp lugs, shrouds, fuse/breaker, DC isolator, busbar | Use short, protected, polarity-marked conductors; parallel paths must be equal length. |
| Inverter AC | Copper XLPE/PVC cable with the required phase, neutral and PE cores | MCB/MCCB, isolator, RCD/RCBO, SPD, gland | Size for continuous current, derating, voltage drop and short-circuit withstand. |
| Controls / monitoring | Specified CAN/RS485 cable, shielded twisted pair or Ethernet | CT, meter, terminators, dry-contact relay, data logger | Separate signal cable from power; follow the manufacturer pinout and shield instructions. |
| Protective earthing | Green/yellow copper PE and equipotential bonding conductor | Earth bar, tested lugs, bonding washers, electrode, inspection pit | Bond exposed metal and keep SPD earth leads short; test continuity and earth resistance. |

These are manufacturer-listed product families, not a statement of Myanmar warehouse stock. Obtain the exact suffix datasheet, serial traceability, authorized-channel evidence and inverter–battery compatibility letter before purchase.
Battery-first design
Battery energy (kWh), battery power (kW), inverter voltage and the BMS protocol must all match. Brand name alone does not prove compatibility.
Balance of system
Protection devices must be selected from voltage, current, fault level, earthing arrangement and cable calculations—not copied from a generic bill of materials.
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.
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.
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
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.
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.
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.
