A six year old Solahart that has changed colour

Let's have a look at a six year old Solahart panel (This system is owned by a young family):

Here's another angle, because it can be very hard to see what is beneath patternised glass:

As one installer jokingly said to me; "White is not a very good colour for solar panels".

The Government, the Green Party and environmental groups like Greenpeace are urging householders to be responsible and "invest" in solar water heating. A 15 million dollar Government campaign has been announced that will encourage approximately 15,000 to 20,000 extra systems to be installed by 2010. This could be a lot of landfill material if my experience proves to be the rule and not the exception.

"But surely these systems have improved over the last five years?" You respond.

You could be right; but I will counter this immediately by pointing out that the three different solar panel models that we have had on our roof are all less than five years old from today.
