Swedish residential units store solar energy for half a year

July 29, 2007 at 10:52 am · Filed under Green Building, Power, Solar

Relying on solar heating might sound like a bad idea if you live in a country that sees little daylight for much of the winter. Yet that’s exactly what 50 households in Anneburg, Sweden, have been doing for the past two years.

During the summer, water is pumped through rooftop solar heaters to warm it, before being stored in pipes embedded in granite 65 metres below ground. The water is kept hot by the rock, and can then be pumped back up to heat homes in winter.

    Good post. That would be awesome to rely on half of year of solar energy, but I don’t know about in a place that doesn’t receive much sun. Keep up the good work.

    This is a really awesome post! Makes me wonder how efficient the rock is at keeping the water warm. This would probably work very well in Arizona, where I live.
