Product Description

Solar PV water heater combines PV panels with a storage water heater.

This heater uses solar and electric energy with AC/DC systems. It utilizes solar DC power for heating at no electric cost on sunny days, switching to AC during rainy weather, ensuring constant hot water.

Specification

No inverter / No storage battery / Free Electricity

Inverter free & no storage battery
Direct DC power heats water, no conversion loss.

Solar powered hot water on sunny days
Switch to AC heating on rainy days for nonstop hot water.

Simple installation
Mount PV panels on rooftops. No complex plumbing needed.

Durable solar panels
Hail resistant, sun proof, freeze free. 30-year PV module life.

High energy saving & low maintenance
Fewer components mean fewer faults, ideal for homes and villas.

Corrosion Resistance: Tank and heating element designed for 10+ years lifespan in hard-water conditions

Eco-Friendly: Zero carbon emissions, approximately 1.5 tons Co reduction per unit per year vs. electric water heaters

solar pv water heater how it works?

A solar PV water heater works by converting sunlight into DC electricity via photovoltaic panels, which then directly powers a DC immersion heating element submerged in the water tank. Unlike traditional solar thermal water heaters that use heat-absorbing vacuum tubes, a solar PV water heater has no circulating fluid, no heat exchanger, and no risk of freezing or overheating.

After Sales Service

Solar panels (photovoltaic) absorb sunlight and generate DC electricity
The DC heating element converts electrical energy into heat, warming the water directly inside the pressurized tank
Polyurethane foam insulation retains heat for up to 24 hours, providing hot water even after sunset
Temperature sensor and controller prevent overheating, automatically disconnecting the heating element at [85°C]
