Focusing on the temperature management of PV


With a background in the development of Low Concentration PV, focusing on the temperature of PV naturally became the next step. Our goals were to improve temperature management of PV modules, without adding costs per Wattpeak, and keeping production uncomplicated.

We utilized Design Thinking –  with a “less is more” approach –  to find a solution that would not add costs, transportation weight or require production changes. The solution resulted in the COOLBACK® design.

Imagine if all solar modules in existence were able to produce more output and have a longer, more productive lifespan?
We would have more sustainable energy, consume fewer materials for production, and reduce the waste and pollution related to manufacturing.

This is what COOLBACK® stands for.

But that’s not all. COOLBACK Company makes every effort to operate and produce in the most environmentally-friendly manner possible. This starts with sourcing raw materials from carefully selected suppliers. Our production and logistics methods are aimed at reducing waste. And we produce part of our own energy. We practice an environmentally-friendly philosophy throughout the entire supply chain.

COOLBACK Company started as a Low Concentration PV (LCPV) project in the Middle East, in 2011. The project focused on a combination of optics and PV. It was subsequently rolled out via Optixolar BV, a Dutch-based enterprise originally founded by Simon Meijer, the current CEO of COOLBACK Company. Following several years of development in the area of Low Concentration PV (2011-2015), it became evident that standard PV modules were the clear winner in terms of energy costs per kWh. This was due to a massive decline in cell prices.

This change in the market called for serious lateral thinking, and it prompted the management and shareholders of Optixolar BV to re-evaluate their objectives. It was decided to completely abandon the LCPV project and to take a new approach in improving solar energy advancement.

A new project was then developed from the ground up, relying on expertise in PV, thermodynamics, aerodynamics and material science. This was the birth of COOLBACK®.

COOLBACK’s aim was to cool down standard modules and reduce heat losses in a structure that weighs less and with very low cost. These design criteria where the benchmark during a 2-year phase of research and testing.

In 2017, things were ready to roll: patent applications were submitted, production and assembly methods had been established, capacity requirements were complete, and certification testing was in progress.

Extensive outdoor performance testing was done – starting in 2017 – at COOLBACK Company’s test location in Sevilla, Spain. Since early 2019, extensive testing has taken place at the Doha (Qatar) and the Zuidbroek (The Netherlands) testing locations.

COOLBACK Company uses unconventional thinking to find solutions for industrywide problems. Traditional engineering (over-dimensioning) was left behind and rapid prototyping and testing was applied to PV module innovation. Agile innovation is key.

Pioneering for the future is important, as COOLBACK® sets the premise for further innovation in mounting, stacking and tracking. Optimizing PV output at reduced costs calls for lateral thinking and questioning current industry standards and conventions.

COOLBACK Company is owned entirely by renewable energy enthusiasts with a proven track record in business development and expertise in wind and solar energy. The management team is built on senior-level industry knowledge. A diverse and international team is dedicated to pioneering a new approach for clients worldwide.
