| SPEED CONTROL SIGNS: Solar & Wind solutions | ||||||
|
Signs can be powered by either Wind turbine,Solar panel or Both together depending on site conditions.
The solar panel is positioned facing south for optimum performance. The energy is stored in batteries housed in a purpose made enclosure fixed to the post behind the sign. SOLAR PANELS Time-tested polycrystalline (multicrystalline) silicon cells with improved silicon nitride (SiN) coatings provide maximum efficiency. Proven technology so you can be assured that the panels are going to work and last for many years to come. Highly resistant to water, abrasion, hail impact and other severe weather conditions. Suitable for use in any climate it's a modern product that meets the highest safety standards. Manufactured in ISO 9001 and ISO14003 certified factories, you can have confidence that the Solar panels are designed and built to a rugged specification, with frames that outperform lighter weight models. Products are certified to IEC 61215, meaning your solar panel will provide the voltage and current well within the industry standards for a given performance rating. Solar panel solutions are highly versatile, so you can string them together easily to increase power or voltage rating. Provides the right current for your application using single or multiple panels. TWM have years of experience providing tried and tested solutions. We have the gained experiance from thousands of installations and learned over time how to get every installation idealy setup so you get the reliability of power you need. Our experienced qualified staff give professional expert guidance to help specify your system requirements. Environmentally friendly power solutions ZERO Carbon emissions so you can "do your bit for the environment" and in reality actually reducing carbon emissions WIND TURBINES The wind turbine generates 90 Watts @ 19 knots and 24 Watts @ 10 knots Low wind speed start up of just 5 knots. More ampere hours are generated because of the turbines low wind speeds start up. Power is being generated in the most typical wind speeds as well as being powerful in the strong winds. Quiet in operation, every turbine is finely balanced to ensure smooth rotation Low friction 3 phase alternators give a smooth and silent output. Automatic thermostatic alternator protection, this slows the turbine down in prolonged gales to give added protection against damage from high winds. Robustly constructed for excellent reliability and product longevity, typically more than 10 years. One way only fit fine profile efficient aerofoil blades are unique in the industry, they have a positive one-way-only fit. They have been tested to withstand a loading with a safety factor 10 times the turbine's maximum rpm. Turbine diameter of 910mm, this is a small turbine diameter for the power it produces. Easy to handle for installation. Built in slipring and low wear brushes gives free 360º rotation on the mounting pole even in the slowest wind conditions. The alternator's windings and magnets are totally encapsulated. Weather Proof, the generator is completely protected from all weather conditions. No radiated interference, complies with EEC Directive BS EN 89/336/EEC Alternative energy can power most of TWM's signs and signals, providing that the right parameters are applied.
