Recently I opened up a surprising can of worms with a blog post about CitizenRe wondering if they had finally solved the problem of making solar power compete with the electrical grid. At that post you will see a substantial comment thread, including contributions by executives of the firm, which I welcome. At first, I had known little about CitizenRe and the reputation it was building. I thought i should summarize some of the issues I have been considering and other elements I have learned.
CitizenRe's offer is very appealing. They claim they will build a plant that can make vastly cheaper solar. Once they do, they will install it on your roof and "rent" it to you. You buy all the power it produces from them at a rate that beats your current grid power cost. Your risks are few -- you put down a deposit of $500 to $1500 depending on system size, you must cover any damage to the panels, and they offer removal and replacement for a very modest fee if you need to reroof or even move. You lock in your rate, which is good if grid rates go up and bad if grid rates go down or other solar becomes cheaper, but on the whole it's a balanced offer.
In fact, it seems too good to be true. It's way, way cheaper than any offering available today. Because it sounds so good, many people are saying "show me." I want to see just how they are going to pull that off. Many in the existing solar industry are saying that much louder. They are worried that if CitizenRe fails to deliver, all their customers will have been diverted to a pipedream while they suffer financial ruin. Of course, they are also worried that if CitizenRe does deliver, they will be competed out of business, so they do have a conflict of interest.
Here are some of the things to make me skeptical.
