We share with you the results of a test conducted with the support of the University of La Sapienza in Rome, to determine the most efficient configuration of three vacuum thermal solar panels. The test compares Pleion X-RAY R solar collectors, in series or parallel configuration.
Here is a summary of the main points:
• Series Configuration: The collectors are connected one after the other, with the fluid flowing through each collector in succession.
• Parallel Configuration: The collectors are connected in such a way that the fluid divides and flows simultaneously through each collector, then converges into a single flow.
The test results showed significant differences between the two configurations, highlighting the advantage of the parallel configuration for most conventional applications:
• Energy Efficiency: more uniform fluid distribution and lower hydraulic resistance;
• Thermal Performance: more stable and uniform temperatures;
• Ease of Installation and Maintenance: requires fewer hydraulic connections. However, for specific installations requiring high temperatures, the series configuration may still be preferable.
PLEION advantages
• Can be installed in both series and parallel configurations;
• Offers flow and return possibilities on the same side;
• Ensures minimal aesthetic impact;
• Improves system performance in every application;
• Allows for significant material savings;
• Significantly reduces installation times;
• Facilitates periodic maintenance;
• Offers maximum flexibility with hydraulic connections on both the right and left sides. How much is all this worth?
According to our calculations, it is worth at least €200 for each collector installed!
