1. Benefits of Coolback

Besides cooling, what other benefits does COOLBACK offer?

In addition to cooling, COOLBACK also gives a added strength to a module, as well as extending a modules lifespan.

COOLBACK’s frameless structure gives added strength to the back surface of a solar module. It offers more support than conventional frames, which only provide support to the rim of the glass.

COOLBACK also prolongs the lifespan of solar units by combatting degradation, caused by high temperatures and bending.

A module’s lifespan is estimated to be prolonged by 20-30%, based on ongoing scientific and test data.

Can COOLBACK be recycled?

Yes. COOLBACK is made from premium aluminum and can be recycled in various aluminum recycling processes.

Does COOLBACK fit all solar modules?

Yes. In principle, COOLBACK® fits all kinds of solar modules.
Solar modules with 60 cells, 72 cells, mono crystalline and poly crystalline can all be equipped with COOLBACK.

How does COOLBACK affect shipping volume?

The COOLBACK system is designed specifically to lower transport volumes. The height of COOLBACK measures 40mm, which is similar to standard frames that measure 30 mm to 40 mm in height. The trick is in the nesting. COOLBACK units can be stacked back-to-back, reducing transport volume by 50%.

How is COOLBACK assembled during solar module production?

COOLBACK is integrated during the framing phase of production using standard methods. Instead of installing the frame during this phase, the COOLBACK system is attached to the back side of a module.

This process is fully automated and done at high speed. Further, COOLBACK Company provides the assembly machine to manufacturers for seamless integration into their process.

How is mounting a COOLBACK system different to conventional methods?

The COOLBACK system placed solely on the back side of a solar module and takes the place of a conventional frame & backsheet. COOLBACK is a frameless, rimless unit that is mounted using clamps that are typically used for glass / glass modules. COOLBACK can provide these clamps or can advise which clamps are best to use.

How much weight will COOLBACK add to a solar module?

The weight of the COOBACK system is comparable to that of a conventional frame & backsheet unit.

The COOLBACK system replaces the frame & backsheet of solar modules during the assembly processes.

Yes. In principle, COOLBACK® fits all kinds of solar modules.
Solar modules with 60 cells, 72 cells, mono crystalline and poly crystalline can all be equipped with COOLBACK.

How does COOLBACK cool a module?

As a frameless structure which is mounted to the back of a solar panel, COOLBACK works by dissipating the heat of a solar module through natural convection and radiation.

This effect is magnified by COOLBACK’s larger surface area (5x larger), allowing heat to dissipate at more easily.

Heat losses in solar modules account for more than a 10% decline in the energy generated by a solar module. COOLBACK plays a big role in preventing these losses.

In which temperatures and climate does COOLBACK work most effectively?

Although COOLBACK works in all climates, it’s most effective in high irradiation areas where the sun’s intensity causes normally high module temperatures.

COOLBACK provides extra cooling when operating temperatures exceed 40°C. In more moderate temperatures, COOLBACK has no extra cooling effect but does offer added structural strength at lower shipping volumes than a conventional frame-equipped module.

Is COOLBACK certified and safe?

Yes. COOLBACK is fully IEC certified, including certification for standards concerning isolation, strength and safety. COOLBACK’s backsheet replacement change has also been tested and approved by the institute.

What kind of extra output can I expect from a solar module using the COOLBACK system?

The extra output generated by COOLBACK can vary between 1-7% depending on the temperature of the standard module and the location of utilization.

By measuring the temperature of a standard module with frame, we get a good indication what the output would be using COOLBACK.

The effects of COOLBACK become very apparent at operational temperatures above 40°C (104°F). For every 10°C above 40°C, an additional 1.4% output can be expected. This really adds up in warmer climates.

For example:

If the operational temperature of a standard module is 80°C, COOLBACK would generate an additional 5.6% in output.
