FAQ

What is off-grid and what is on-grid?

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 turbine should you pick?

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
Where should you put your turbine?

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. 

 

How do you measure your wind?

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 you get your wind turbine?

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.

How do you connect and install your product?

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 you choose the right product?

We would be happy to help you to choose the right wind turbines to reach your sustainable development goals. Please contact us by email.

Can I order more than one product at a time?
You should because then you benefit from the cluster effect of the turbines making their neighbors perform more efficiently.
What makes Flower Turbines special?

We try to solve all the issues of small wind turbines that could prevent them from being used in a tight environment, near people, and near and on buildings. As a starter, they must be quiet and pleasing to the eye. Our game changer is that our wind turbines perform better when close together.

We also provide solar and charging solutions for e-bikes so you can also encourage clean transportation.  

How many wind turbines will power a house?

How many turbines will power my house or business? We can answer that if we know your electricity consumption, the wind speed, the size of your property—on the ground or on the roof– and the size of wind turbine you can fit.
