Why Solar Projects Fail
Battery Under-Design
Small battery capacity causes unstable lighting during rainy or winter seasons.
Result: system failure during low sunlight periods.
Solar Panel Under-Performance
Undersized solar panels cannot fully recharge the battery.
Result: reduced brightness and shorter working time.
Environmental Mismatch
Harsh environments include:
Coastal salt corrosion
High humidity regions
Desert UV exposure
Result: structural aging and sealing failure.
Installation Errors
Common issues:
Solar panel shading
Wrong orientation
Incorrect pole spacing
Result: unstable system performance.
Incorrect System Sizing
Mismatch between road width and lighting design causes uneven illumination.
Result: dark zones on roads.
