As the world deal with the unprecedented virus, the economic shock wave almost derails wind and solar industry progress.
Renewable energy have growth over past two decades, avoiding amounts of greenhouse gas emission.
The coronavirus pandemic will depress U.S. electricity markets and hurt generators in 2020, the U.S. Energy Information Administration says.
There are three main impacts on 2020 wind energy industry below.
1. Coronavirus threatens 35,000 US wind jobs
2. Supply chain disruptions lead to delays in completing projects
3. The risk of being unable to benefit from government incentives at the end of this year
In the US. the world's second-largest renewable markets after China. However, Both of them fight against Covid-19 right now. No one is a winner.
Wind generators have a natural appeal to sailors in need of extra power. Our customer installed it on sailboat to help supplement his solar panel. He almost lives on the sailboat. Some people asks us which power supply (Solar panel or wind turbine) is suitable for his/her sailing boat. Budget are always the top problem that stop them from purchasing both power supply. However, we recommend using both at the same time.
Hawaii is a state of the United state of America located in the Pacific Ocean. As you may know, throughout the year, Hawaiian weather are affected by trade wind and there are plenty of rainfalls in the mountains and valleys. Because of wind trade, there is always cooling breeze here.
Above pictures are from one of our customers, he lives in Hawaii. He installs this home wind turbine on his own. He is a good customer providing some installation info to us.
He uses 8 AWG wire and the interval between the wind turbine and the MPPT is 35ft. The battery capacity is 230Ah. The interval between the MPPT and the battery is 3ft. The tower height is 25ft. The wind speed in his area is 10-30mph.
It's happening! Our "Three Brothers" wind turbines is doing their live performance on Container House. Even thought the weather is not so good, they still perform pretty well. What's more, the ticket is totally free. Come to join us and you will not regret.
This is our special guests "power bank". They are responsible for store your batteries and then take advantage of the build-in pure sine power inverters to turn DC current to AC current.
Come to join us and you will not regret. Trust me!

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.
