So is the facility being built a manufacturing plant or just an engineering/research lab?


With them saying this, "that will increase its production capacity in Massachusetts by 70 MW and double its employee base in the state to more than 600 employees" I would assume it's a manufaturing plant but it's on the MTC campus.

I'm the biz developer for Evergreen so I think I can speak with some authority on this: The MTC location will be a factory only; research will remain in Marlborough and our personel overhead should not really increase with the build. The vast majority of the addtional workers are production not administrative or research.

I love this blog btw... cheers.


Thanks for the insite Nol. I've been following ESLR for about 6 months and wish you guys all the luck on your String Ribbon technology.

Can anyone make a comparison with the String Ribbon technology vs. the technology of let's say First Soloar's cells??? Solar specs are something I'm a complete novice at so any info would be appreciated.

Dante Paolillo

In few words, First Solar's cells are cheaper, but are less efficient than Evergreen's ones.
You'll need more pannels (more surface) to obtain the same power.
First Solar: 7% conversion efficiency
Evergreen Solar: 14,5% conversion efficiency

Jimmi, this site www.worldwater.com provides some real time data. Three locations in California at capacity factors if 4%, 5%, and 18%. One NJ site had 13%.

Doubling conversion efficiency does not addup to very much electricity with poor capacity factors.

When it comes to solar, let the buyer beware. The solid state components that convert variable solar panel output to usable 120VAC coat about $5000 and have a warranty of 5 years. If you connect to the grid you must have a special breaker and a contract with the utility. It is a safety thing. I know of one case where solar panel never produced electricity because the cost of the lawyers to negotiate the contract was not factored into the project. It did make a pretty picture on a government web site.

Oh, those evil utilities. In this case it was a muni that claimed to be the greenest.

well I think this is a great idea, I'm glad, and I really expect that you keep talking about this
