Why Silentwind? Because it is whisper quiet compared to other small wind generators
The quietest small wind generator is finally available in Australia and New Zealand.
The SILENTWIND® wind generator from SPRECO offers maximum safety and efficiency with minimum noise emission. Designed by sailors for sailors in Germany and the world.
Whether it powers the batteries in a sailboat that is thousand of miles off land or

Myth about Solar PanelsSolar Panels are getting better and cheaper all the time. However there are certain facts about solar panels sales people never tell the customers. Marine solar panels like all other panels are rated in terms of their output wattage and voltage. The majority of solar panels are either Monocrystalline or Polycrystalline panels. The Monocrystalline panels have better peak performance but are shade sensitive and their output diminishes quickly on cloudy days. Polycrystalline panels have usually less output and are more cost effective and less sensitive to shade. All solar panels best performance is when exposed below 25 degrees centigrade and the output will diminish when they heat up. The rated output figures are rated of 1000 watts/sqm energy from sun light at a 90 degree angle. Panel performance drops off quickly in poor light. Output drops by 30% if the panel is angled 45%, by 40% in light overcast condition and 80% by when its heavily overcast. The facts are that solar panel only produces its full power under very rare condition. |
