![]() Configure the weather measurement devices alert system to let you. Using the given import(buy) tariff, and export(sell) tariff and the clean energy cashback feed-in tariff for a system of the chosen size, we calculate an estimated value for each year. Know wind speed and direction easily, thanks to the Netatmo Wind Gauge Weather Station.We display this under the Energy Projection tab.Any energy that is not used on site, we mark as exported.Using the locations energy use and the chosen energy use profile, we match the wind turbine installations output with the energy used. As previously stated, different measurement units can be selected with the cup vane wind speed meter: m/s, km/h, knots, ft/min and mph.This is the calculation we use to give a guide price based on the peak output of the chosen turbine. We have analysed a number of wind turbine installation quotes provided and developed a price calculation that you can review here.We calculate this value for each month of the year.Finally we apply a reduction factor to allow for inverter and cable losses that occur when the wind turbine generation is converted to a form suitable for use in a property or for exporting to the grid.Each model is listed at each of the mast heights that are available. You can choose any of these turbines from the Turbine Model drop down under the Wind Turbine tab. We have a list of most wind turbine models and their specifications available here.There are several types of anemometer to choose. You could go out and buy one, but I find it much more fun to build my own. We use an average turbine power curve to estimate the output of a generic turbine with the chosen peak power at a particular wind speed. One of the best ways to measure wind speed is to use an anemometer. Best accuracy in a home weather station Durable (has withstood up to 199 mph winds and wildfires) High-quality sensors Cons Expensive, and no internet connectivity out of the box Dated, bulky.Finally we apply a factor to account for buildings being nearby and the location being an urban environment.We use a mathematical tool called the Weibull Curve to account for this in our calculation. The wind does not always blow at the average speed given by the wind database, most of the time the wind blows well below the average, however as the energy that can be converted to electrical energy is related to the wind speed cubed, higher wind speeds produce exponentially more energy than lower wind speeds.You can read more about this calculation here Because wind speed increases as the hight above ground level increases, and the NOABL database we use is for 10 meters above ground level, we use a wind sheer model to adjust the wind speed at the height of the proposed turbine based on the Location Type under the Wind Turbine tab.This distribution is taken from the NASA POWER projects database of world renewable energy resources You can take a look at it We then calculate the distribution of this energy over an average year.Given your location, we look up the average wind speed using the NOABL wind database.The RenSMART Wind Turbine Estimation Process 1.
