The marketing problem facing solar thermal is quite complex. It's not just the bad deals and fallout of the early 80's that it has to get past, but now it's also competition with other energy-saving products in a similar cost range. I think the "simplify" message is beginning to move in the right direction but even to me that seems like more of an operations method than a marketing tool.

In PV, the face of the industry experienced an overhaul when grid-tie was introduced in the early 2000's. Solar thermal still feels like it is stuck in the off-grid era and that it hasn't benefited from a policy overhaul in the same way PV did.

A big problem? Consumers have no concept of how much money they spend heating water. They know their electric bill to the penny. They might know their natural gas bill, too, but often water heating is only part of that alongside a gas stove. If it's rolled in to a heating oil bill, water heating will be a small bump. So communicating the value of solar thermal is very challenging when put up against these issues.

Kudos to you all for working on tackling these issues. There are few folks working on marketing solar thermal and there's a lot of work to be done.

Hi:

As a person that has been involved with RE, particularly solar, forever (business and non-business) Pam is correct in most if not all her assertions.
Two important facts here. PV did not really take off until grid tied entered the equation. That happened for a multitude of reasons. Second, because of this, any person has the option of benefiting from producing more power than they use and storage is never an issue. These facts are huge and not to be underestimated.
From an engineering perspective, PV is not susceptible to diminishing returns due to approaching a finite load. Any installation for all practical purposes can "view" an infinite load with infinite returns. Even if most do not take advantage of this, it is a carrot that is available. Second, thermal is more complex than PV, again, for a multitude of reasons. So I agree that taking something that is complex and making it appear simple is beneficial for marketing, (as example, computers are really anything but simple), you can only go so far and still meet the engineering demands for a given system in a given location when it comes to solar thermal.
