The X-Sol 100 is our innovative Solar Water Heater currently produced under licence by our partners in Argentina and India.
In 20 years of practical work with common solar hot water systems we observed many problems, especially under the harsh conditions found in sun rich countries and high mountain areas. These experiences have lead to multiple improvements integrated into the unique, simply and robust design of the X-Sol 100. Over 3000 units have been sold so far in Argentina, prooving this redefined solar water heater concept. It is the only locally produced hot water system in Argentina, which can compete with low cost evacuated tube systems.

The main benefits of the X-Sol are:


Modular design
Easily customizable in steps of 100L, from100L to 500Lover the integrated cold and hot water rail. The hot water supply canbe adapted flexibly to the actual demand and the financial possibilities
No corrosion-
long lifetime
Due to the use of high quality plastics corrosion does not exist, even with salty or brackish water!
Freezing tolerant
No requirement of anti freezing agent. This was prooven with hundreds of installations on the Argentinian Altiplano at temperatures below -20°C.
Highly compact
The whole system comes assembled in one casing. Easy to transport, easy to install even without a plumber. Requires cold water and hot waterconnection only.
Low stagnation
temperature (98°C)
Even if not used over long term, the system will hardly reach boiling point, thus material stress, evaporation of drinking water and scaling is avoided.
No theft
X-Sol does not contain copper or other valuable material which attracts thieves.
Optimized materials
The absorber's food grade rubber material withstands 120°C and the tank 100-110°C. No copper is used
Low risk of scaling
The big heat transfer area keeps local temperature in risers low, reducing risk of scaling. Scaling is also prevented by the use of plastic material.
Good efficiency
In the common temperature range of up to 50°C the system can compete with standard Chinese evacuated tube systems.
Easy maintenance
Easily maintained by the users due to the use of local materials

Launch of X-Sol in India:

X Sol India

In August 2018 the X-Sol was launched on the Indian market, with our parter Opti Engineering.

The first 55 X-Sol were shipped to Kenya in 2019. In June Simply Solar successfully trained the plumbers
of our Kenyan distribution partner Moxie Power in the installation of our modular X-Sol
system on residential and public buildings.

One of the first sites was the Chogoria Hospital:

After a successful trial period with four X-Sol's over a few months, Chogoria Hospital intends to
completely shift to environmentally friendly and economically favourable solar hot
water generation. With each X-Sol potentially over 1000 kWh of electricity can be saved per year.
