AC&T are a UK consultancy specialising in ventilation technology for both commercial and residential properties and buildings. They have compiled a year-long assessment of a SolarVenti SV 30 model, which assess its yearly efficiency, airflow, and generally puts the claims made by SolarVenti to the test.
The full report, complete with graphs and equations, can be downloaded here:
However, if neither science or maths are your strong points, here is a quick over view of some notable nuggets of info from the report.
- The theoretical maximum energy output was regularly exceeded, even despite some slight shading and the unit being mounted vertically on a wall. In short, the SV 30 device was actually more powerful than SolarVenti claimed.
- Efficiency of the unit during the winter months was higher than anticipated - few, if any, other solar devices can provide 55% efficiency during January. According to many online reports, the average efficiency of many solar products during winter months is well below 15 per cent, so in this context the SV 30’s performance during this period is mind-blowingly good.
Airlfow, which SolarVenti tell customers is a minimum of 120m3/hour, actually averages 150m3/hour.
- The SolarVenti SV 30 provided measurable reductions in space heating and therefore reduced CO2 emissions, all of which contribute to reduced energy bills and massive savings over a year-long period.
Baseline temperature in the target room was significantly increased after the installation.
All in all, this is a very promising write-up and should go along way to propagate the benefits of solar ventilation to tech-skeptics.
People want scientific proof, well, here it is folks. It’s all there, and it doesn’t have make for an interesting read once you get past all the scientific jargon. That said, geeks will have a field day perusing the report!
