I. Application Scenarios

Versatile installation solutions designed for diverse architectural environments

SOLETKS Solar Installation Scenarios

The solar panel mounting system offers multiple angle brackets (0°, 25°, 45°) to accommodate diverse roof structures. The adjustable bracket angles allow precise alignment with roof slopes, ensuring seamless integration for flat roofs, sloped surfaces, and irregularly angled roofs. This innovative solution effectively addresses the common challenge of "difficult solar panel installation on roofs" by providing adaptable mounting options that perfectly match structural characteristics.

Villa

Luxury homes with flexible roof designs

Pointed Roof

Sloped roofs with various angles

Flat Roof

Modern buildings with horizontal surfaces

Multi-storey Residential

Apartment buildings and complexes

Adjustable Mounting Angles
25° 45°

Multiple bracket angles ensure optimal solar panel positioning for maximum energy collection efficiency across different roof types and orientations.

II. Core Advantages

Five key innovations that redefine solar water heating performance

SOLETKS Core Technology

The efficient utilization of solar energy is crucial in product design. This all-in-one unit boasts a solar absorption ratio of up to 95%, capable of heating even under average sunlight conditions while efficiently collecting heat. Compared to traditional electric or gas water heaters, it requires no substantial energy consumption, saving household expenses and reducing pollution – perfectly aligning with the green living philosophy.

1

Efficient Heat Collection
More Efficient Energy Utilization

The efficient utilization of solar energy is crucial in product design. This all-in-one unit boasts a solar absorption ratio of up to 95%, capable of heating even under average sunlight conditions while efficiently collecting heat. Compared to traditional electric or gas water heaters, it requires no substantial energy consumption, saving household expenses and reducing pollution – perfectly aligning with the green living philosophy.

⚡ Energy Savings

95% solar absorption rate reduces electricity costs by up to 70% annually

2

Natural Circulation
No Power, More Easy

The water heater adopts the design of non-powered natural circulation, which uses the horizontal density difference between hot and cold to realize water circulation heating. There is no need to consume electricity, reduce operation cost and failure probability, and users do not need to worry about pump maintenance, so they can enjoy stable hot water safely.

🔧 Zero Maintenance

No pumps, no moving parts – reliable operation for years without service

3

Multiple Capacity Options
Suit Family Differences

Different family population, different water use habits, different demand for capacity. A variety of specifications to meet the needs of different families for hot water.

150L
3-Person Family
200L
Medium Household
300L
Large Family
👨‍👩‍👧‍👦 Perfect Sizing

A family of three selects 150L to meet daily needs; larger families choose 200L/300L

4

Operating Under Pressure
Enjoying a Torrential Rain

The water flow fluctuates during the shower, significantly reducing the experience. The water heater operates using a pressure-boosting water storage tank, with the water pressure entirely determined by the tap water pressure – No matter how much hot water remains in the tank, the showerhead maintains a steady flow of water, avoiding the issue of "the more you use, the weaker the flow becomes."

💧 Consistent Pressure

7 bar working pressure ensures powerful shower flow from first to last drop

5

Enamel Inner Tank + Magnesium Rod
Durable and Hygienic

The tank's quality determines both the water heater's lifespan and water quality. The all-in-one unit features an enamel tank with porcelain interior and steel exterior. The ceramic glaze layer is fixed on a specialized steel plate through high-temperature baking at over 830℃, resisting long-term erosion from 100℃ hot water while preventing corrosion and scaling. Combined with magnesium rods for corrosion protection, these rods actively react with corrosive substances in the water, extending tank durability and maintaining clean water quality – giving your family peace of mind with every use.

🛡️ Long-lasting Protection

830℃ enamel coating + magnesium anode = 10+ years of reliable service
