Solarkilns design is extremally effective at converting the suns energy into directly heating the kiln. A revolutionary, environmentally friendly drying system developed and proven in the timber industry with wide ranging applications where product drying and dehydration is required.

Industries Solarkilns can help with are:

  • Agricultural / Food Products
  • Sludge / Waste Products Dehydration
  • Minerals / Hydroscopic Salts Final Drying

Solar Kilns Design

The elegant multi-layered plastic design of our drying system is strong, long lasting and extremely effective at converting the suns energy into directly heating the kiln.

Timber Drying

Conventional timber drying methods have peaked their maturity levels after decades of optimizing research. Solarkilns have developed and proven “Cyclic” drying that works with the daily cycles maximising the solar kilns operation.

Superior Technology

The kilns control system has been developed over 25 years to capture, store and maximise the benefits of free solar energy, to heat the kiln enabling the drying of timber and many other products.

Solar Collection

Principle of operation

Solarkilns dome kiln design makes the most out of daylight hours energy absorption. The dome shape is installed in a North/South alignment providing a large surface area facing the sun’s direction from sunrise to sunset. Whenever sunshine is on the kiln, solar energy is being absorbed into the kiln.

The kilns advanced control system works in harmony with day/night cycles and automatically adjusts the operation of the kiln to make the most out of cloudy days where intermittent sunshine is available. In fact, the control system even knows when a cloud blocks out the sun and adjusts to suit as you can see here.

Daylight Mode

Energy Absorbtion

Airflow through the inner cavity transfers re-heated air in to the kiln

Reversing main circulation fans distribute heated air during the solar heating phase

Night Time / Cloud Stall Mode

Energy Conservation

Air flow through inner air space stops

Outer and inner air spaces act as efficient dual insulation layers

Reduced air flow within kiln

High humidity treatment period and heat storage

Environmentally Friendly


Our Solarkilns have had over 25 years of development to be able to offer the user the many benefits of solar heating and the advantages of a superior faster proven cyclic drying method

Good News For You and the Enviroment

The lightweight construction makes solar kilns very economic to purchase, and inexpensive to erect on site. In locations where solar contribution is optimal, kiln operation can be programmed t operate on solar only for the required thermal energy input into the kiln. Alternatively, a hybrid combination of solar thermal energy and auxiliary heating can be used. Auxiliary heating methods available such as LPG, Natural Gas, steam, hot water, heat recovery and many other options.


Another saving for both the hip-pocket and the environment is a typical ‘Solarola’ technology Solar Kiln. Working in moderate climate zones, producing energy savings valued at approximately 4-6 times their upfront cost over a ten-year life span. Now that’s good karma!
