Vacuum Tube	Size (mm)	Φ581800 / Φ471500
	Tube (pcs)	40 / 50 / 60
	Glass	Borosilicate 3.3 glass with high vacuum, featuring a double layer design, is an incredibly durable and versatile material. Its unique composition allows for superior strength and resistance to thermal shock. With its exceptional heat resistance and transparency, it is commonly used in scientific and laboratory applications. The high vacuum capability of this glass ensures optimal performance and reliability in various environments. Its double layer construction further enhances its insulation properties, making it ideal for insulation and containment purposes. This type of glass is highly sought after for its exceptional quality and reliability.
	Coating	AL/AL-ALN(H) is a single-target approach, while Cu/SS-ALN is a three-target approach. There are differences in the focus and composition of these two materials. AL/AL-ALN(H) is primarily designed to target a single objective, whereas Cu/SS-ALN is capable of targeting three objectives simultaneously. In the former, the emphasis is on achieving high precision and efficacy with a single target, while in the latter, the focus is on multitargeting capabilities. Both approaches have their own advantages and can be used in different applications depending on the desired outcome.

The vacuum tube material used is borosilicate glass 3.3, which offers excellent durability and heat resistance. To enhance its performance, an AL-SS-CU absorb coating is applied. This coating helps the vacuum tube efficiently absorb and retain solar energy, making it an ideal choice for solar water heaters and other solar thermal applications.
6. Collector mounting: flat roof or inclined roof

Working Principle

An active open-loop solar system operates by connecting solar vacuum tubes directly to a manifold tank. These tubes contain cold water that is heated through solar irradiation. Due to the difference in specific gravities, the hotter water rises towards the manifold tank, while the colder water descends back into the vacuum tubes. This continuous circulation gradually heats the cold water in the manifold tank. Simultaneously, the hotter water from the manifold is pumped into a hot water storage tank. This process allows for the circulation of colder tank water back to the manifold collector for further solar heating. Through this efficient system, solar energy is harnessed to provide heated water for various purposes.

Competitive Advantage

1. It is the most economical solar collector which is widely used in large-scale hot water heating system, supplying hot water for dormitories, hotels, restaurants, schools, hospitals, factories, swimming pools, and other places requiring large amount hot water application.

3. INLIGHT glass tube collector can be connected in series-parallel arrays and used in active or passive solar water heating system with stable and reliable performance.

4. INLIGHT glass tube and manifold is anti-freezing device, the collector can be used in extremely cold area with anti-freezing system design and pipeline insulation.

5. High absorption: αs ≥ 90%, low-emissivity: εh ≤ 8%, daily average thermal efficiency ηd ≥ 50%

6. INLIGHT modularized design makes the collector more adaptable to different architecture structure and locations.
