Zillow Advice: Heating & Cooling - At what cost would it be affordable to convert to solar heat? http://www.zillow.com/advice-thread/At-what-cost-would-it-be-affordable-to-convert-to-solar-heat/235509/ Zillow Advice | Zillow Real Estate Solar heat effectiveness ... http://www.zillow.com/advice-thread/At-what-cost-would-it-be-affordable-to-convert-to-solar-heat/235509/ Solar heat effectiveness depends upon many variables.&nbsp; One of the most important being what region one lives in and how much exposure they have to the sun.&nbsp; <br/><br/>Solar hot water is practical in many locations as a supplementive means of providing hot water.&nbsp; One must look at the payback time to best understand costs of solar.&nbsp; There are many tax credits which vary from state to state.&nbsp; If I were to look at solar as an option, which in my case I would hold off a few more years until solar panels drop in price, I would first check out my states energy section on its website for information relevant to tax credits and solar programs.&nbsp; <br/><br/>Another factor which is critical for solar heating is what type of existing heating system does one have, building insulation and construction,&nbsp;size constraints for panels.<br/><br/>I believe solar has a great future ahead, but personally am waiting for it to become more cost-effective.&nbsp; When solar panels become cheaper to produce and more efficient I myself will consider a supplemental hot water system tied to a wood-gasification heating system here in chilly New England.
