Services

We can be involved in every step and are experienced project managers when it comes to solar thermal installation.

Processes we are often involved in include:

- Presenting options for the site's size, area and layout.
- Owning contact with the surveyor to ensure correct markings for pipes and solar collectors. 
- Owning contact with consultants, government officials, museums, etc.
- Managing construction site during solar collector- and pipe build. 
- Ramming steel profiles with our own equipment and team.
- Executing pull/peak test of the steel foundation - including necessary documentation.
- Installing solar collectors, individual connection of all collectors and connection to the pipe system.
- Delivering flexible steel hoses, vents, jacket pipes, and more.
- Delivering and completed application of glycol - including necessary documentation.
- Performing pressure tests and preparing for commissioning.
- Airing out and adjusting plant pressure.
- Calculating and adjusting balancing valves - including any minor adjustments.
- Owning construction site safety and general order on site.
- Documenting quality control (QC) and quality assurance (QA).

Solar heating is a well-known, simple, and effective type of energy that can be a financially advantageous addition to existing energy sources.

We offer all services related to commissioning your solar thermal plant. We can commission new solar plants and recommission existing plants after rebuilds and break-downs.

The following are typically the steps necessary for commissioning:

- Prepare for commissioning, including checking the entire plant.
- Delivery and filling up the glycol (if necessary).
- Starting up and commissioning the plant.
- Follow-up walk-through of the plant to ensure there are no leaks, air pockets, etc.
- Incoming-regulation and flow balancing of the solar thermal site (especially for new plants).

Our experienced service technicians have completed numerous plant commissioning and we are very flexible regarding what time of day the work is performed.

In case the solar thermal plant experiences a stagnation we are ready to move out quickly and ensure a correct restart. We will complete a thorough check of the solar thermal plant to locate any causes or errors, and to discover the cause of the stagnation.

In case of special tasks, such as repairing a leak in a pipe in the ground, we are ready to consult on the best and most financially sound solution with the goal of limiting the plant down-time. Similarly, we are also ready to assist by project managing the contractors needed to solve the project.

With experience from numerous solar thermal plants in all sizes and designs, we have found solutions for all possible challenges.

A solar thermal plant that is regularly serviced ensures security and reliability - both financially and operationally.

We offer a service contract that can include:

- A fixed, annual walk-through and a status report on the plant's condition.
- Online support and error-finding.
- Support for operational optimization, for example with a monthly operations report and suggestions for improvements.
- Annual glycose analyses.
- Discounted hourly rates.

We offer both large and small, as well as individually customized, service reviews for your plant.

A service check on a solar thermal plant is more than just a check of the solar collectors and possible leaks. The pressure conditions and levels of glycol are also significant factors for the plant's longevity and the quality of its produced energy.

For example, if the pressure expansion system is not performing optimally, the plant will most likely be functioning in a state of alarm. In the worst case, the pressure may be too low and this will damage the pump. Or, if the pressure is too high, there is a risk that it will activate the pressure safety valve.

Additionally, there will not be room for the expansion and decompressions necessary in the daily workings of a solar thermal system. Remember that the liquid can go from 20-30°C all the way up to 90-100°C within a short window of time once the sun hits.

The temperature quality from the solar collectors is also a significant parameter, and by measuring the outlet temperature on each solar collector row, it is possible to determine how well the flow balance is performing. In some cases, there could be a risk of localized stagnations in the solar collector due to limited flow. This can create unnecessarily high temperatures and cause leaks around valves and connections.

The physical status report is not enough in itself. We ensure full documentation of all observations and the completed work. This guarantees tracking for many years to come, and can be used for reporting, for example, for board meetings.

If you do not have a service contract with us, please feel free to reach out to learn more about what it can include and how it can support your solar thermal plant.

We offer operational analyses of your solar thermal plant and its connection to the heating plant's existing energy sources. Backed by years of experience, one of our major strengths is the identification of optimization options and how to get the existing solar thermal plant to provide more. We believe in a practical approach to operational analysis, and are available to help with training and descriptions of operational functions. With our hands-on operations experience from many different solar heating systems, we are also able to set up a support contract where we can assist with remote support by logging onto your plant to help - either in critical situations or during normal operations. We call this a "live" operational analysis and adjustment of parameters and set points.

Our operational analysis works with the historical operational data and it allows us to offer both a complete review of the entire solar thermal plant or more specific problem points. The operational analyses will always be customized to your specific district heating plant.

We offer a quick and affordable analysis of the solar thermal plant by accessing operational data from 1-2 days of stable service. The result of this analysis is typically a review of the flow conditions, temperature levels, as well as calculations for potential operational improvements - for example, changing the defined temperatures. With this analysis, you will be ready to identify possible optimization options.

The historical operational data is also an important factor to consider when the district heating plant's energy production is looking to expand or be converted. Maybe it is an extension of the solar thermal plant where the actual pump- and heat exchanger capacities need to be examined beforehand. Or it may be the addition of a heat pump and its temperature levels can have a positive effect on the solar thermal heat and vice versa. With specific and targeted operational analyses, the foundation for any major investment decisions is solid and based on actual conditions in the heating plant. We partner up with the heating plant and control systems supplier to plan, execute, adjust and test the control strategies.

If the ongoing collection of operational data is not available, we have solutions that can easily be installed in the existing plant, and which collects the specific data that is necessary for a further analysis. We can provide customized, automatic data collections and calculations that result in operational reports. This type of ongoing reporting is especially valuable for board members and other stakeholders.
