What is off grid and what is on grid?2019-10-08T01:59:12-04:00

On grid means that you attach your system to the utility. Off grid means that you live independent of the utility and provide all your own power.

An on-grid system doesn’t need a battery because you use electricity and sell your extra to the grid and use grid electricity when your wind system doesn’t produce enough. In effect, the grid is your safety backup.

If you disconnect from the grid, it means that you need extra capacity to make sure you can charge your batteries, and that your batteries have enough capacity to carry you through periods of no wind and no sun, if you own solar. Having wind and solar together gives you a greater chance of being able to recharge your batteries.

You have to determine the capacity of your batteries by looking at your electric usage and by knowing how long, in the worst case, you might have no wind (or no solar) energy feeding the battery. To go off-grid, you should plan on having extra energy capacity and extra battery capacity for worst case scenarios.

In an off-grid system, your wind turbine’s output passes through a charge controller into a battery and from there into an off-grid inverter, which synchronizes to the voltage (120 or 240) of your house or building without synchronizing to the grid.

What size of turbines should you pick?2020-12-09T11:02:41-05:00

You can adjust your available space and the power available from the different turbines. The bigger and larger the turbines, the more cost effective, in general. One has to take installation costs into account. Our wind turbines perform more efficiently in a cluster effect.

Here is a table about the way to locate the different sizes, in general:

Size Location
Large (6 meters high) Land or very strong roof
Medium (3 meters high) Land or strong roof
Mini (1 meters high) Land or regular roof
   

Now you are ready to place your order with information about number of turbines, size of turbines, the electrical capacity of the turbines. Have a look at our prices here.

Location of a wind turbine2020-12-11T08:21:45-05:00

Determine the place where you want to put your turbine. An area of higher wind is almost always the best choice.

If it is on a flat area, ground or roof, you should have exact measurements of the location and the direction of where most of the wind comes from. You will ideally place your group of turbines so that they are side by side perpendicular to the direction of the wind.

We can help you to determine the best place for your wind turbines when you send us your weather station data. 

 

Measure your wind2019-10-08T02:07:57-04:00

The most important thing you can do first is measure your wind with one of many reasonably priced and commercially available kits, often called weather stations.
If the average wind speed is 6 meters per second or above, you almost always have a great return on investment. 5 meters per second usually means a good return on investment. Gusty wind is better than lower but steady wind.

Look at some free online resources to get a feeling as to whether or not you are in a high wind area. There is a caution that comes with all these resources. Wind can be very specific to a specific location and height. Many of these resources don’t tell you exactly where they were measured and at what height. They are useful as a starting approximation.

International information: Weather Underground: https://www.wunderground.com/

USA.com: www.usa.com

Enter your location, then click on Others, and scroll down to the bottom of the page for the wind graph.

International information: Meteoblue: https://www.meteoblue.com To take full advantage of this site, click on the left side bar where it says Archive Climate and then under it Weather Archive. It takes you to a page where you can get wind speed measurements or projections over the course of a year.

US Department of Energy: https://windexchange.energy.gov/

This site has useful information in general and has links to wind maps of each state. Many countries have their own meteorological services and provide data to the public.
You can take that approximation and generalize by asking yourself questions: Are those websites generally accurate about what I feel the wind is? Is my location open on all sides so the wind can come through easily? Is my location in a geographical wind tunnel that accelerates the wind and makes it higher than the norm in my area?

Ultimately, the best solution is to invest a small amount of money and get data from a weather station. Look for one that produces a spreadsheet so that the data can be analyzed. The more often the weather station can take readings, such as every 10 seconds instead of every minute, the better. We do not make these weather stations. We simply recommend any of the reputable models that are in the price range of $100- 200 each. If you are building a wind farm involving megawatts, then you should approach one of the commercial testing services.

When do I get the wind turbine?2020-12-09T11:10:52-05:00

The estimated shipping date from the ordering date is 6 – 15 weeks. We are happy to provide you with an estimated delivery date. Please contact us.

What happens if I cancel my order or pre-order?2019-10-08T01:52:05-04:00
Refund minus 50 Euros or dollars administrative charge. Temporarily, pre-orders in the US are fully refunded, but that will change shortly
What are the color options?2020-12-09T11:13:12-05:00

The standard for wind turbines is white and, for the smallest size, blue and black. For an additional charge you can choose any RAL color you prefer. We can also provide our products with a customized logo.

The standard for our Charging products is green, but we are able to deliver the charging products in any RAL color. There is usually a charge for non-standard colors.

 

How do I connect and install the wind turbines or/and Charging products?2020-12-09T11:15:28-05:00

You will need a local installer. Our current default is to ship our wind, charging, and solar products ready to install.

After physical installation, an electrician should make the electrical installation.

We are happy to help you with the installation. We work with qualified partners who can help you with the installation in some locations.

 

How do I choose the right electronics for the turbine?2019-10-08T01:46:53-04:00

See the page www.flowerturbines.com/customers . Here is a summary of some important points. In most cases, you will connect your turbine directly to the utility grid, in which case you will receive an inverter. If you want to go off-grid and supply all your energy from wind or wind plus solar, you will need a battery system (not supplied), an off grid inverter, and a charge controller to connect the turbine to the batteries. If you already have a solar system with batteries, we need to give you a charge controller that fits your current battery voltage; email us the information when you purchase. If you want such as system and have not purchased it yet, we recommend batteries with minimum voltage setup of 48 volts. If you want to connect wind and solar panels to a new system with our turbines, let us know and we will supply you with a hybrid charge controller.

In general, it is best to email us when you order and reference the order number. Information that will help us help you includes:

  • Your location and how windy it is
  • Your choice of on-grid or off-grid
  • Whether you have or intend to get solar also, and if you do, what electronics you currently have, and what is the voltage of your batteries, if any
  • Configuration of the planned location for the turbines with a simple map. Flat roof or slanted? Area available on the ground?
