SolPal ICS Passive Solar Water Heater

Due to its perfect combination of a solar collector with a hot water storage tank, SolPal® is more efficient than traditional thermosiphon systems. SolPal® is a compact system with an integrated hot water tank that is suitable for the most diverse applications. Whether you own a family home, a villa, a holiday resort or a weekend retreat, SolPal® is the ideal solution.

SolPal Benefits

• Save up to 80% of water heating costs
• Save up to 30% of total energy costs
• Best price/performance ratio
• Hot water 365 days a year

Replace your current power source entirely
Unlike traditional thermosyphon systems, the water heater is integrated directly into the collector, which means that the sun's energy is transferred directly to the water heater. This is not only fast, but also ensures that the water is not polluted.

Significant cost savings
Reduce energy costs for producing domestic hot water of up to 80%. The sun is an unlimited energy source. Making use of it is good for the environment, conserves resources and is kind to your wallet. The new hot water system SolPal® is able to exploit this free solar energy better than all other comparable models thanks to its boosted efficiency. The simple, compact and efficient design of the SolPal® ICS system offers an extremely high price/performance ratio. Add to this its durability, and you get a cost-effective system which will provide free hot water to your household for years.

Hot water 365 days a year
When the sun is shining, every traditional thermosyphon system should work well. The new SolPal® system works more efficient every day of the year and can be installed as a stand-alone unit, in combination with external energy sources or connected to other units in series.

Easy installation; lower costs
SolPal ICS systems are easy to install. The solar collector and hot water storage tank are incorporated into a single, compact casing. Installation is as easy as plumbing the cold water feed and hot water return into your existing domestic hot water system. This is truly a “plug & play” system. SolPal® can be installed on flat or pitched roofs.

More efficient than thermosiphon systems
When compared to traditional thermosiphon systems, the SolPal ICS is superiorin collecting heat from the sun, and transferring it to your household water. And in areas where direct sunlight is not always available, the water tank backup will supply hot water for your household.

Sleek design
The SolPal ICS system offers a sleek profile that follows the contour of your roof. Optimized visual appeal is achieved through blending of form, function and material. Traditional thermosiphon systems are bulky and do not blend in well with their surroundings.

SolPal Specifications:

Most sources of water are ok for this system. As a precautionary measure we suggest you take a water sample to a local water conditioning company for a no cost/low cost water test.

Important Note: Two factors that are important for use of these units are water quality and potential freezing.  Water quality is an important factor for these units as they are made of 444 stainless steel.

Specifications for Water Quality:
SolPal should not be installed if the water quality does not conform to the specified limit values. If you should still choose to install SolPal, this will void your warranty.

Below are links to websites where you may purchase kits to test your water mineral content:

• Chloride content, kit SB46613M
• Other mineral content, kit 481199

Freeze Protection:
SolPal may be installed in areas within the United States that experience mild winter climates. Because of the huge mass of water inside the SolPal, the System does not freeze. However, the SolPal must be drained if the temperatures have ever fallen to:

10°F for 6 consecutive hours, or
20°F for 18 consecutive hours

When these environmental conditions are met or exceed the SolPal must be manually drained in accordance with the installation instruction. Failure to do so will void the warranty coverage.

How does it work?

Water is heated directly in the solar collector and held in the accumulator (patented single-circuit system). This allows a substantially greater energy saving and can reduce energy costs for producing domestic hot water by up to 80%. By continuously tapping fresh warm water, an optimal hygienic standard can be guaranteed too.

Easy Plug & Play Installation Video (Flat Roof)

The pre-assembled plumbing package shown in the video and manual is not available in the U.S.; the plumbing kit includes U.S. approved parts which can be assembled to meet the requirements of the installation.

Mounting Options:

Includes standard factory 
flush/tilt mounting brackets 
(shown on image on left)

Flush Mount - underside of unit attaches directly to the mounting surface. For tile roof applications where the tile roofing is installed around the unit, or use with angled rack mounts.

Fixed Mount - aluminum frame supports unit slightly above mounting surface. For shingle or tile roof applications where a space is desired between the mounting surface and the unit to allow for air flow and rain runoff.

Tilt Mount - aluminum frame supports unit slightly above mounting surface, plus tilts collector to desired angle for increased solar performance. Can also be used for ground mounts applications [cement pad or footings required].

Flush mounting the collector to a pitched roof:

Depending on the local installation codes, the flush-mount hardware that comes packaged in the SolPal box might require additional parts to comply with these codes. If your state requires that you raise the collector above the roof on some sort of substructure, you can select one of our System Mounting Kits, or you will need the following parts to finish securing the collector to the roof (parts not included):

• Unistrut rails for the collector to rest on the roof.
• 5/16" bolts with channel nuts & springs to secure the bottom of the SolPal 'L'  brackets into their unistrut rails. 1 each per connection needed (typically need 6 connection points)
