WIND
1. Can I use a small wind turbine to power my house? 2. What information do I need to become energy self sufficient? 3. How do I achieve the most cost effective solution? Most often the best solution is achieved by a combination of energy solutions such as: 4. How much energy do my appliances use? Please refer to the table below for energy usage of appliances. So you want to install some renewable energy for your business or home and have come to the crossroad as to which is better, wind power or solar power? Both wind power and solar power have been around for a long time now and both renewable energy sources have successfully been used to produce clean electricity for home and commercial users. But which renewable energy source is the best for you ? Criteria Wind Energy Solar Energy Description Working hours per day 24 hours ±5 hours Risk of theft/vandalism Low High Solar panels are easier access than wind turbines Effect of dirt Low High When solar panels get dirty it loses some of its performance Effect of snow Low High The output of a wind turbine i not effected by snow Temperature effect Not effected by temperature High As the panel temperature increases, the electricity output reduces. Footprint Low High A 1000w solar panel would have a footprint of 7.3 sq.m whereas a 1000w wind turbine would have a footprint of 1 sq.m 1kW wind turbine Wind Speed (m/s) Monthly Energy (kWh) Equivalent Solar Panel Capacity (W) 3.0 49 327 3.5 77 513 4.0 110 733 4.5 146 973 5.0 184 1227 5.5 223 1487 6.0 261 1740 6.5 297 1980 7.0 330 2200 Diversified Products (trading as Renewable Solutions) is the renewable energy and energy efficiency. With developed technologies that provide the opportunity to customers to better use the natural resources available to them in an efficient and productive way that doesn’t hurt the environment. WE now provides a full range of small wind turbine solutions in 600w, 800w, 1kW and 3kW range. Because of their robust construction and unique engineering, turbines have proven to be the product of choice for telecommunications, off-grid, grid connected and water pumping solutions. For all these reasons, shouldn't you be riding on the winds of change too?Wind Power Basics
