this is a very good point. would be good to see data for a couple of years of production and compare vs. traditional system. it's most of the time better to spend upfront for ongoing production increase. If 5% loss during 25 years, 20% upfront saving might not look that good anymore for a plant that pays back in 7 years or so.

The response of the company when the issues of heating, vegetation, snow, and rain is... I guess I am not impressed. > The expert added, “I’m also concerned about the lack of airflow around the module in this system design. Glass-glass modules provide a good moisture seal, but I suspect the back of the module will have very high humidity with no airflow. Damp-heat testing will be important. Not sure what other organic stuff could grow back there, like fungus or mold or things that get in the J-box,” referring to the junction box that houses the equipment that carries electricity from each panel. > Daniel Flanigan, chief marketing and product officer at Erthos, offered this response: “No developer is going to install an Erthos system without proper diligence and all of these issues…being resolved. Yet we are engaged in over a gigawatt of pipeline.” Okay, got it. So because people are paying for it people should pay for it.

  That's what they said about Theranos, too.

  I agree. sounds like a red flag when they reply with "yeah everyone is buying it so your question is irrelevant" instead of providing a technical explanation/response. I am also skeptical on companies that raise too much funding (I can not imagine why they need $18million)

Consider the difference in borrowing costs now too. A 20% higher upfront cost means a 30% higher cost if you include financing over several years. So it will be good to see how the alternatives work out
