The Ensun-Flat Plate Solar Collector is engineered for high-efficiency performance and long-term durability in residential, commercial, and industrial water heating applications. It features a selective coated absorber, toughened solar glass, and corrosion-resistant components. Designed to perform well in a wide range of climates, it is an ideal solution for centralized hot water systems, with strong certifications including ISO 9001, CE, and RoHS.
The Ensun-Flat Plate Solar Collector uses a flat absorber plate made from aluminum or copper, coated with a highly selective surface to maximize solar energy absorption. Encased in a well-insulated weather-resistant box with tempered glass, it captures sunlight efficiently to heat fluid in the copper pipes. Its simplicity in design allows for fast installation and easy maintenance, making it a popular option for both residential and commercial projects.
The collector is particularly efficient in areas with high solar irradiation and is ideal for rooftops, balconies, and flat areas. With a wide operating temperature range and strong structural integrity, it offers excellent thermal output year-round.

The U pipe solar collector constitutes multiple parallel tubes organized in U-shape used to convert the sun’s energy for heating purposes. Usually, these tubes are made from metals such as copper with high thermal conductivity.
To enhance solar absorption, the collector is often installed on a roof or a frame with the tubes towards the sun. The fluid flows naturally thanks to the collector’s U shape without the use of pumps or additional energy creating a thermosiphon.
U pipe solar collectors are a preferred option for solar thermal applications due to their many benefits some of which are highlighted below:
Compared to other solar collectors these have straightforward design with fewer parts making them more affordable. Their lack of supplementary pumping systems makes their installation and maintenance costs lower and thus a decent investment.
U pipe collectors are often constructed of durable and corrosion-resistant metals like copper. This guarantees performance in the face of adverse conditions enabling dependable performance that is long-lasting.
The wide surface area of these solar collectors effectively accommodates heat transfer when exposed to solar radiation. The collector heats up uniformly along its length thanks to the U-shaped design, maximizing the absorption of energy by the fluid.
Since they use solar energy that is renewable, U pipe solar collectors minimize reliance on fossil fuels. As such, they help create a more eco-friendly and clean environment by lowering carbon footprint and greenhouse gas emissions.
