closing up rew 2009

Today ends Renewable Energy World 2009 Confrence & Expo in Las Vegas….it was a great event, I got to reconnect with many friends and business partners in the industry. I did notice this year the attendance was quite low compared to the last couple years so you can say that the economy has caused companies to scale back in the renewable energy industry too.

I want to share some interesting pictures with you. Below is a typical setup of how a grid tie system is connected your electric meter. The picture highlights a Solectria residential solar grid tie inverter, on the left side of the inverter, thats the DC disconnect. On the right side, thats the AC disconnect right above the revenue grade utility meter. Doesn’t seem too complicated, wouldn’t you agree?

I got some great close up pictures of the Skystream 3.7 wind power system. A user friendly feature of the Skystream 3.7 is that the grid tie inverter is built into the head of the wind turbine. The picture below shows the housing in which the grid tie inverter sits inside.

A closeup shot of inside the head of the Skystream 3.7 that shows the guts of the grid tie inverter. The downside to having the inverter and communications interface built into the head of the inverter is that if you ever need to service the grid tie inverter you would have to access the top of your tower, which could be very inconvenient. What do you think? Regardless, the Southwest Windpower, the company that makes the Skystream 3.7 booth at the trade show will continuously busy, it seems like there is still extremely high demand for their products.

The back of the housing seems to features a heat sink cover to help the built in grid tie inverter to stay cool, notice the short antenna? That’s there to monitor the output and overall performance and health of the system through a wireless connection.

Anyways, I hope you enjoy this short review of our experience at the leading renewable energy expo of the year. If your interested in checking out more pictures of our experience please check out our community!
