Which is best for you, on-grid and off-grid

12/26/2019

Comments

 
What's the First thing that comes to your mind when you hear the word "off-grid" and "on-grid" ?
Pardon, 
What does it mean to be off grid?  What is difference between on grid and off grid?
Let me clarify something for you. 
👇👇
What is On grid ?
A
 home that is connected to locally provided power source is considered “On-grid”. 
An on-grid can be practical if the following conditions exist:
You live in an area with an average annual wind speed at least 10 mph (4.5m/s). Utility-supplied electricity is expensive in your residential area. The utility’s requirement for connecting your system to its grid are not prohibitively expensive.

What is off grid?
Systems are not connected to a local utility supplier are known as “off-grid”.
An off-grid can be practical if the following conditions exist:
You live in an area with an average annual wind speed at least 9 mph (4m/s).
A grid connection is not available or expensive. You would like to gain energy independence from the utility.

Wind generator in cold climate

Do you know a blade cover with 5 mm of ice can reduce power curve by as much as 80%?
Do you know icing is a major problem for aircraft, wind turbine and power lines?
Do you know why people choose to set up their wind turbine in this cold region?

Picture

Rather than waiting for the ice on the blades to be removed by direct sunlight or higher temperature, we have to find some active methods to protect our expensive wind turbine.
The problems occurs for wind turbine operating in cold region.

✔ Accumulation of ice on wind turbine blades resulting in reduced power output and increased rotor loads
✔  Mechanical and electrical failures due to higher load on blades
✔ Limited or reduced access for maintenance activities
✔ Measurement and control error and other safety hazard
Picture
Actually, there are a variety of different approaches to remove ice from blades. IEA wind recommends heating outer surfaces of blades or using Atifreeze coating.
Furthermore, there are various ice protection system technologies available on market.

✔ Hot air ice protection systems have a heat source combined with a high powered fan to circulate hot air to different areas of the blade.
✔ Electro-thermal ice protection systems have heating elements, typically carbon fibre, placed on the outer surface on the blade
✔ Microwave ice protection systems have a special outer coating on the blade surface that heats up when exposed to microwaves created by generators inside the blade
✔ Passive systems use blade coatings with special material properties to passively (no energy required) mitigate ice induced risks

The cold regions tend to have low population density and high wind speed which make them particularly attractive sites for setting up a home wind turbine.

How to live off the grid

Have you ever dream of self-sufficiency like Tom and Barbara in The Good Life? Living in the remote country after retiring with your wife or husband? or Getting rid of hustle and bustle of modern life desperately? Still don't know how to get started, then here are few tips for you below.
1. Find the best spot for your off grid home
Top best 3 states suitable for off grid living:
 Hawaii 
Hawaii's weather is warm all year around and soil is rich. Its rainy season is on November to March. There are plenty of rainfall as well.
 Missouri 

Missouri laws are friendly for those who want to get away from society. There are plenty of green acres and mountains. The climate is also warm and humid.
 Alaska
This state is a popular consideration for off-griders. This population density is sparse. And you may found a group of experience outdoors people here. Water is easily available in Alaska, Black bear, brown bear, moose, caribou and deer can be hunted here. 
2. Set up your water collection system
You can just simply install rain barrels or harvest water with swale.
3. Grow your own food
These plants such as tomatoes, peppers, cucumbers, radishes, zucchini, and pumpkin can be grew easily for the beginners. 
4. Find alternative energy
Wind and solar systems are the most popular and feasible methods for off-griders. Using solar panel as a main power to supply your daily use on the daytime and wind turbine as a back up power at night.

How to install Automaxx Windmill Wind Turbine

12/18/2019

Comments

 
Finding your best location for your wind system
Locate your wind turbine in windy sites so as not to disturb neighbors and animals around. The better location of your turbine requires avoiding personnel or animal activities within a 33 ft (10m) radius, and human habitation and wildlife within 66 ft (20m) radius.
Purchasing a pole kit from your local hardware outlet
The minimum recommended tower height for Automaxx windmill turbine is 22 ft(7m) to 33 ft(10m).
There are three types of Automaxx windmill pole kits.
Pole kit
Pole kit for land
Pole kit for marine

Choosing your wind turbine battery
​The capacity of your battery bank is determined by your use. Battery price might be your first concern. Nowadays, there are multiple battery options on market. e.g. Flooded Lead Acid, Lithium Ion, and Deep Cycle Battery. In general, we will recommend our customers using Deep cycle battery.
For further information, you could visit Battery Council to get to know more about battery.

Things to consider before purchasing a wind turbine

The amount of wind at your site
If you live in the U.S., you can estimate the wind source in your area by referring to the wind resource maps provided by the U.S. Department of Energy's Wind Powering America Program.
​
The zoning requirements and covenants in your area
You can find out about the zoning restrictions in your area by contacting the local building inspector, board of supervisors, and/or planning board.

Estimating appliance and home electronic energy use
Knowing your electricity usage is a must before installing a wind turbine. 
Following steps below.
1. Find wattage of the product
 
2. Estimate of time used
3. Find the daily energy consumption by using this formula
   
(Wattage × Hours Used Per Day) ÷ 1000 = Daily Kilowatt-hour (kWh) consumption
4. Find the annual energy consumption by using this formula
    
Daily kWh consumption × number of days used per year = annual energy consumption
​5. Find the annual cost to run the appliance by using this formula
    
Annual energy consumption × utility rate per kWh = annual cost to run appliance
