Glycol Solar Panels

It s non toxic biodegradable and relatively stable.

Glycol solar panels.

The information contained herein is based on data considered accurate. This glycol is completely non toxic safe for all types of solar heating applications and is made from sustainable bio based raw materials. Propylene glycol pg has become the most common heat transfer fluid used in closed loop solar heating systems that contain antifreeze. In most solar heating applications the solar collectors are exposed to periods of freezing as such the solar heating heating fluid needs to be able to with stand freezing.

Antifreeze fluids degrade over time and normally should be changed every 3 5 years. Fernox solar s1 is classified as non hazardous and non irritant but as with all chemicals keep out of the reach of children.

However no warranty is expressed or implied regarding the accuracy of these data or the results to be obtained from the use thereof.

When commissioning a pressurized glycol solar hot water system it is essential that all the air in the solar loop is removed. All glycol products used in solar fluid mixes come with a dilution chart an example of which is shown below. Typically any time a system has a glycol bulk temperature in the range of 250 f 121 c fluid degradation increases. In all three scenarios if a glycol fluid is used the residual glycol remaining in the panels becomes acidic and can cause corrosion issues.

It has a long track record over many decades in this application and is widely available from a number of sources. This is done through the use of mixing water with specially formulated solar glycol to avoid freezing and large scale damages. By code any solar application involving potable drinking water must use a non toxic blend of solar glycol known as propylene. The industry standard for solar fluid is a mix of propylene glycol and water.

Glycol is now pumped out of the bucket filling the solar collectors from the bottom to the top. The formulation should not be diluted prior to use. Solar water heating systems that use an antifreeze solution propylene glycol or ethylene glycol as a heat transfer fluid have effective freeze protection as long as the proper antifreeze concentration is maintained. At first air returns into the bucket and then glycol mixture with air and foam which can be very hot.

Air in the loop can cause pump. However you should always mix as much water as possible with your choice of glycol product as simple water is the ideal solar fluid. Air in the collectors and the pipe is pushed out the purge hose back into the top of the bucket by the charge pump.
