Yeah, when I was looking into this a couple of years ago, thermal panels were about 4 times as efficient as photovoltaic panels, but they were also 4 times as expensive. The ratio has probably shifted in favor of photovoltaics since then. If you have very limited space on your roof solar thermal can still be a good idea, but otherwise why prefer low grade energy (heat) over high grade energy (electricity) if you can get the same capacity at the same price? |
