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 illustrated below.

Good news for the you and the environment

The lightweight construction makes solar kilns very economic to purchase and inexpensive to errect on site. In locations where solar contribution is good, kiln operation can be programmed to operate on solar only for the required thermal energy input into the kiln. Or a hybrid combination of solar thermal energy and auxilary heating can be used with auxilary 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 average climate zones, produces energy savings valued at approximately 4-6 times their upfront cost over a ten year life span. Now that’s good karma.

In most cases, the deliverable additional savings each year due to unique features of this technology will pay for the kiln.
