Over the past 30 years residents have begun to use solar collectors for hot water.

Last year, a passive solar collector on a house would have been expected to pay for itself in 12 to 15 years.

The solar collectors also provide hot water to the house all summer long.

They can function as a sail, a solar collector, or both at once.

It took time to right you, and your solar collectors usually got damaged.

The light from the solar collectors made him narrow his eyes till he got used to it.

The system includes 18 solar collectors and cost around $15,000.

If not the stove, it had to be the solar collector.

But there was a heat source out by the solar collector.

The solar collector was given a clear field of sunlight.
