They are made from high-grade materials that are durable and long-lasting and come with a warranty to ensure customer satisfaction.
By choosing Goldstar Solar Water Heater, you can reduce your dependence on traditional water heaters that consume electricity or gas and lower your carbon footprint. This not only helps in protecting the environment but also saves you money on your electricity bills. Overall, Goldstar Solar Water Heater is a smart, reliable, and sustainable choice for heating water in an eco-friendly and efficient way.
Goladstar’s Bharg solar water heater model is an advanced and extremely efficient system that utilizes evacuated glass tubes to capture and transfer solar energy. These tubes have two layers of glass with a vacuum in between, creating an insulated space that reduces heat loss. The heated water is then collected in a storage tank, where it can be used for various purposes.
Thanks to the evacuated glass tube technology, the Bharg model is highly efficient and can generate hot water even in low sunlight conditions. Additionally, the model is ideal for use in areas with colder weather conditions due to the vacuum layer in the tubes, which prevents heat loss and maintains the water temperature for a longer period of time.

The Goldstar RAY Model is specifically created as an economical and budget-friendly option to cater to hot water requirements through solar water heating. Among its peers, RAY is considered the most inexpensive solar water heater available.
Despite its affordability, RAY has a tank that is optimized for corrosion resistance. The tank is constructed with high-grade GI steel to ensure durability over an extended period of time. Additionally, the outer cover is coated with premier powder on GI made from Poly Propylene resin, which safeguards against UV rays and corrosion and ultimately results in a longer lifespan with no maintenance required.

A Flat Plate Collector solar water heater is a type of solar water heating system that utilizes a flat, rectangular collector plate to capture and transfer solar energy. The plate is typically made of copper or aluminum and is coated with a special material that absorbs sunlight and converts it into heat. A network of pipes, also made of copper or aluminum, runs through the plate, and a heat transfer fluid, typically water, is circulated through the pipes.
The heated water is then stored in an insulated storage tank until it’s needed. Flat Plate Collector solar water heaters are highly efficient and can provide hot water for various applications, including residential, commercial, and industrial settings. They’re ideal for use in areas with moderate to high levels of sunlight and are suitable for use in areas with mild to moderately cold weather conditions.
