✅ 1. Energy Efficiency

• Heat Pump: Uses ambient air to heat water with up to 70% less electricity. Doesn’t rely on sunlight.

• Solar Water Heater: Zero electricity usage when the sun is available — but performance drops on cloudy or rainy days.

Winner: Heat pump (more consistent savings all year round)

✅ 2. Weather Independence

• Heat Pump: Works day and night, in all seasons, including monsoons and winters.

• Solar: Fully dependent on sunlight. Needs electric backup on cloudy days.

Winner: Heat pump (ideal for Tamil Nadu's varied climate, including hill stations)

✅ 3. Installation Flexibility

• Heat Pump: Can be installed on terraces, walls, or ground level. Suitable for homes without sunlight access.

• Solar: Requires direct sunlight and roof space for solar panels.

Winner: Heat pump (more location flexibility)

✅ 4. Maintenance & Lifespan

• Heat Pump: Low maintenance with glass-lined tanks, especially when combined with descaling.

• Solar: Regular maintenance needed — panels, pumps, and valves require care.

Winner: Heat pump (especially in hard water areas)

✅ 5. Cost Comparison

• Heat Pump: Higher initial cost than solar, but provides faster return on investment through consistent savings.

• Solar: Lower upfront cost, but needs electricity backup, reducing savings in some seasons.

Winner: Depends on usage. For year-round reliability, heat pump is preferred.
