Why Choose Solar?

Posted by HTP on Feb 20, 2015 10:00:00 AM

Obtain freedom from high fuel costs while protecting the environment with solar options from HTP!


  1. You Care -  Each solar panel eliminates tons of carbon dioxide from being released into the atmosphere.  It would take the planting of 40 trees per year to recoup that much CO2. Collecting and using solar energy reduces fuel consumption, be it electricity or natural gas (15,000 cubic feet of natural gas or 4,000 BTU per day for each solar panel) *Consult local utility rates for your area.
  2. Solar Heating Pays Off - Choosing Solar saves you money by cutting your electricty of gas use
  3. Rebates lower the costs - There are numerous incentives to help lower of the cost of solar. Federal Tax Incentives, State rebates and incentives, utility rebates and incentives and even local city or Municipality Rebates and Incentives.

Here are some helpful links to help you find solar rebates:

Sizing Your Solar Hot Water System

Posted by Rod Hyatt on Sep 3, 2014 2:13:55 PM

Below is some information from AskRod.com about sizing a solar hot water system for your home. AskRod.com is created by Rod Hyatt, HTP's National Solar Manager.  -- 


In late spring, I published a chart that helps size a solar hot water system for your home, but after hearing from some people I realized I needed to make it more simple.

So, to back up and provide a bit more information:

This chart shows what system is right for you, using actual sizing logic instead of guessing. (Believe me, I see that more than you’d think.) Instead of a rule of thumb, it considers a southern or northern location in the U.S. to determine what the incoming water temperature might be. The amount of energy you’ll need is based on raising the water temperature from where it starts as it comes into your home. With a little math, we can easily determine how much solar will be needed to fill up the tank, based on the incoming temperature.

The chart lists four choices of collectors with differing measurements. For example, if the load requires two 10-foot collectors and your roof height is only 7-feet tall, you still have several choices to make them fit nicely on your south-facing roof. (Unless you live in Brazil, then please face them north.)

Simple Solar Water Heating Design Trick: Heat The Water You'll Actually Be Using!

Posted by Rod Hyatt on Jul 11, 2014 4:17:43 PM

Read on for a tip on efficient solar water heating, from HTP's National Solar Manager Rod Hyatt.


For the most efficient solar thermal design, solar-heat the water heater first.  I know that may seem self-evident because it’s the water heater that you’ll draw from when you run a bath. But I continue to see system designs where the solar storage is heated first.

So, basically, the water heater is using fuel to warm the water for your bath, while the sun’s hot water is being stored. Does that make any sense? Why not heat the water you’re actually using?

Always heat the water heater first —  and then send the over-flow heat into a storage tank. It is paramount that solar is delivered as close as possible to the point of use. Don’t send solar heat to a distant storage tank that feeds the water heater. Feed the water heater first.

And don’t pre-heat the water heater. Let solar do as much as it can. Here’s how to achieve this simpler, more efficient design.

This first drawing is for a design that will heat solar water in residences, as well as the commercial arena —  laundry, restaurant, hotels, car washes and apartments. It would also work with residences that have side heating loads — such as fan-coils, a pool or hot tub. It features the Mon Con water heater. The Mod Con stands for modulating and condensing — condensing gives you the 96% efficiency; modulation gives you lower firing rates to react more efficiently to the solar input.         

The second diagram shows a design for a low-temp space heating, with the Versa Hydro water heater being heated by the sun first.
