Solar hot water prices

The prices of solar hot water heaters vary with size and the design, largely dependent on climate.

The thermosyphon design (for moderate and hot climates) is much cheaper than the drainback design or other solar designs used in colder climates.

These last types of systems have pumps, controls and anti-freezing elements that make them more expensive.

As expected, solar hot water kits are cheaper than common customized systems, even when these are highly standardized...

Solar Hot Water Prices in cold climates

In today's USA market the average prices of drainback and active solar hot water systems (composed by panels, storage tanks and also pumps, antifreezing and controls to respond to colder climate conditions) is in the range of $3,000 - $5,000.

These systems can fulfill the hot water needs of average homes, that is, around 50 to 100 gallons (190 to 380 liters) of hot water per day...

Solar Hot Water Prices in moderate and Hot climates

Simpler water heaters - some of them without circulating pumps, sensors and controls - for moderate and hot climates are obviously cheaper. You may find prices between $1,000 and $2,500.

solar space heaters Prices

Simple solar space heating solutions (often wall solar air heating systems for individual rooms, without pumps and controls) are relatively inexpensive. Prices in the range $700 - $1000 per panel/room are common.

Other more complex solar air-space heating systems demand a more sophisticated design and maintenance, and a large area of solar panels, which make them a costly solution (more expensive than common solar water heaters).
