Understanding Solar Thermal Installation in Quick Points

Prior to installing your solar water thermal system, you need to find out the angle, location, and direction on the house. The basic prerequisite is to open the solar collector to gather enough sunlight every day and the entire year. 

It is also ideal to talk with different installers who will provide you a quote for the thermal installation. Not only that, it is essential to obtain a surveyor that is MCS-accredited to inspect your area. The surveyor will also be the ones to estimate the output of your solar thermal system as per the geographical property factors. 

Now, these are just some key guidelines to take note of. Below are other key installation guidelines for your solar thermal system.

Solar Thermal System Installation 

As mentioned, only those who are MCS-accredited individuals are eligible to install a solar thermal system. A standard solar thermal installation involves the following steps: 

  • A solar thermal system is mostly a plumbing exercise for engineers with a bit of system assembly, roof installation, and electrical wiring. 
  • The run-through can differ from unit to unit, depending on the specific elements that your solar thermal system is comprised of. Examples of this are displaced tube collector, unventilated cylinder, or flat plate collector. 

Key Factors to Consider 

These are the aspects to consider when having your solar thermal system  installed: 


As much as possible, solar collectors should face each other closely which is the noontide sun. Based on the position of facing the equator, it means that in the northern hemisphere, solar collectors must face south. As for the southern hemisphere, solar collectors should face north.

Although it’s not always ideal to mount solar collectors facing north or south, 45 degrees west or east is recommended. This will not decrease the output of solar energy being collected. Also, when collectors are facing more on the east, it increases exposure towards the morning sunlight. More exposure to the afternoon sunlight when faced on the west. 

It is also required to add a larger solar system when pointing away from the equator since it decreases the daily solar output. System designers should consider this when installing a solar thermal system. 

Installation Perspective 

When it comes to perspective, solar thermal should be installed facing the sun in order to get sufficient exposure to sunlight. The angle should be up to 15 degrees higher than the locations’ latitude. This ensures maximum heat output for the entire year. A higher or lower perspective, depending on the application, can be more applicable as observed by the solar installing system experts. If you need a contractor to hire check out Sungrow.  

Solar Collector Spot

Solar thermal collectors can be mounted on the roof, wall, or even on the ground. The key determinants for collector positions are the following: 

  • Shadow — Establishments, trees, chimneys, etc. that may create a shadow on the solar collector in the morning and afternoon. These are the times when solar radiation is mostly given. 
  • Storage tank distance — Having a shorter pipe size can diminish the installation cost, usage of energy, and heat loss. 

Premium Craftsmanship 

The most integral aspect of the solar thermal installation is a professional and expert installer. Just like how people can be so keen when installing cat6 cables to get the best network connection, solar thermal installation is no exception. One must have a good solar thermal system for it to work accordingly. 

Managing System Control 

  • Ensure to check the generation meter – This should be checked by MCS-certified professional. The heat produced from your solar thermal system should be monitored according to the heat liquid flow. This is required for the main purpose of renewable heat incentive calculation payment.

A trained electrician will install and control the generation meter from your solar thermal system. Also, the heater element immersion from the meter will be monitored by the MCS-certified electrician. 

  • Control facilities —  This part needs to be monitored meticulously. The installation varies depending on the specific system you have. But, for the most part, these are automatic systems that pump maximum heat possible. The collectors pump greater heat levels to the thermal and store during needed times. 

Solar Thermal System Pressure 

The transfer of special heat fluid will be infused into the system’s closed loop. The heated fluid is developed mainly for solar heating systems working for a maximum of 200°C. It contains special reversible and vaporizable inhibitors that protect all metals located in the solar heating system. 

Not only that, but it also serves as a freeze-resistant to temperatures as low as -23°C and is biodegradable and non-toxic. The heated fluid is then pressurized depending on the manufacturer’s exact level specifications. 


A Solar thermal system can be complicated most especially during the installation process. Understanding the basics of the process will give you a better idea of how it is done. Having a solar thermal system in your home helps in saving you more energy costs as it collects solar energy from the sunlight.

Also, take note that the installation should always be done by professional installers for the system to work accordingly and perform at its best.
