Flat Panel Collector
Tube Panel Collector
Flat Panel vs Tube Panel, what is best?
Cost is typically the primary consideration. Collector for collector, evacuated tubes can cost around 20% to 40% more to buy than flat panel collectors.
Generally, evacuated tubes perform better in colder and/or cloudier conditions than their flat panel counterparts. They also perform better in an east or west orientation. However in summer time with high temperatures tube collectors can produce super heated steam in excess of 200 degC resulting in more water loss and maintenance. In a north facing installation a flat panel performs equally as well as the tube panel in getting the geyser up to 55 degC.
Installation
Evacuated tubes are typically less sensitive to sun angle and orientation than their flat panel counterparts. Their circular design allows sunlight to pass at an optimal angle throughout the day.
Flat panel collectors are more sensitive to sun angle, and may require the use of a frame to maximize their efficiency and production.
When considering which technology to use please feel free to contact us directly. We will be glad to look at both technologies and see which is the best fit for your specific application.
