Turn sunlight into stable hot water and guaranteed savings for 10–15 years.
Built for hotels, factories, and commercial buildings demanding continuous performance and maximum energy independence.
SOLETKS Solar Water Heater systems are engineered to capture solar energy efficiently and convert it into reliable hot water for homes, businesses, and industries. With advanced flat-plate and heat pipe technologies, our systems deliver outstanding performance, energy savings, and environmental benefits. Each model is designed to meet diverse installation needs and climate conditions, making solar water heating more efficient and sustainable than ever.
A compact system that combines the solar collector and water tank into one integrated unit.
It offers easy installation, reliable operation, and excellent heat retention—ideal for homes and small-scale applications where simplicity and efficiency are key.

This system separates the solar collector from the storage tank, allowing flexible installation according to building layout.
The split design minimizes heat loss, provides better freeze protection, and ensures stable hot water supply in all seasons.

Equipped with vacuum tubes and advanced heat pipe technology, this model delivers rapid heating and superior efficiency even in cold or cloudy conditions.
It is suitable for regions with varied climates and users seeking high performance with minimal maintenance.

A solar hot water system captures solar radiation and converts it into usable thermal energy for domestic hot water, commercial demand, industrial processes, or space heating support.
It significantly reduces dependence on grid electricity, gas, diesel, or LPG.
Higher energy prices = faster payback = higher ROI
Solar thermal is not a trend — it is a mature, field-proven technology. Perfect for:
The more hot water your facility consumes, the more you save.
Solar thermal is not only an environmental solution — it is a powerful financial tool.
A solar hot water system integrates three essential components:
Guest rooms, staff dormitories, kitchen wash, laundry
Solar covers >65% annual hot water energy.
Predictable morning/evening usage
Sun heats during the day → usage at night → perfect cycle match.
Sterilization wash + bathing + cleaning
Hot water demand 365 days → fastest ROI among all sectors.
Food, textile, dyeing, laundries, dairy, poultry
Process water 40–70°C → solar thermal is unmatched in cost.
(For Reference)
European energy prices are high. Hotels have permanent hot water demand. The more expensive the energy, the faster the payback.
MENA has the best solar irradiation globally + high hot water demand. Hotels, resorts and staff housing generate exceptional financial returns.
Laundries and industrial washing operate at high and stable temperatures → Every day produces real savings.
Solar hot water is an energy investment, not a decoration.
| Region | Typical Energy Source | Energy Cost | ROI Performance |
|---|---|---|---|
| Europe | Electricity / Gas | High | 3–4 years |
| MENA | Electricity / Diesel | Very high | 2–3 years |
| LATAM | Electricity / Gas | Medium | 2.5–4 years |
When daily hot water demand is constant, solar thermal becomes a real cash-flow generator.
Heat is a bigger cost driver than electricity in many commercial buildings.
Soletks flat-plate collectors are designed for long-term commercial use, not consumer backyard kits.
Maximizes heat gain while minimizing radiation losses.
Ensures uniform fluid distribution, high thermal conductivity, and zero localized overheating.
Eliminates spot contact, preventing thermal fatigue and solder cracking.
91% light transmittance, anti-impact, anti-hail resistant.
Outdoor durability >15 years, resistant to humidity and UV exposure.
Stable thermal output without performance drop after 2–3 years, even under heavy-duty loads in hotels or hospitals.
Soletks collectors are engineered for high-duty, commercial operation:
Soletks optimizes the entire hydraulic system, not just the collector's kW rating:
Higher outlet temperature, lower pump energy
Consistent loop temperatures across collector strings
Prevent backflow and night losses
Extend collector and fluid life
Predictable thermal performance with minimal instability, even under fluctuating loads.
Soletks tanks are built for frequent, high-temperature cycling:
Maximum corrosion resistance
Minimal heat loss
Extended tank lifespan
Multi-source integration capability
No rust, insulation collapse, or early failure. Designed to operate reliably for 10–15 years in hotels, hospitals, and industrial facilities.
Unlike many suppliers who sell panels and random tanks, Soletks designs complete hydraulic architectures:
We deliver solar hot water SYSTEMS, not isolated components.
Soletks systems are built to withstand extreme environmental conditions:
High-UV EPDM & silicone sealing
Aluminum alloy anti-salt spray coating
Collector fluid compatible with antifreeze
Mechanical structure validated for strong wind and hail
Every design decision aims to reduce field maintenance:
Even in countries where maintenance cost > equipment cost, Soletks systems remain economically viable.
Many solar systems look great in year 1, die in year 3. We engineer long-term stability, which directly increases ROI:
Our performance is steady, so your return is steady.
For EPC, hotel operators, and industrial users, we provide:
We don't send "catalog PDFs" — we deliver engineering you can actually install, run, and maintain.
Soletks Solar is chosen not because we are cheaper, but because our systems stay stable under real consumption when customers truly need hot water.

We are a solution partner — not an installation contractor.
| Item | Electric Heater | Gas/Diesel Boiler | Soletks Solar System |
|---|---|---|---|
| Running Cost | Very high | High | Near zero |
| Payback | None | None | 1.8–4.5 years |
| Lifespan | 5–8 yrs | 5–10 yrs | 15–20 yrs |
| Safety | Power outage risk | Explosion/leak risk | Safe and stable |

Traditional heating gets more expensive over time.
Solar gets cheaper the longer you use it.
Yes. The system is designed with a backup heater or heat pump. Solar provides primary heat; auxiliary kicks in only when needed.
Most commercial projects: 2–5 years. Heavy-load applications (hotels, factories): 1.8–3.5 years.
No. Periodic inspection of valves, pumps, and fluid — very simple.
Yes. We offer: Remote design, Installation guidance, Standardized spare parts, Distributor & EPC training
For projects, partnerships, or technical consulting:
We return a financial model and system design.
