The technology manufacturer Chemik Group aims to grow its global business by 25% to 30% in 2026, driven by new solutions for solar photovoltaic (PV) projects and an international expansion strategy in key markets. The announcement was made by Héctor Erdociain, Chief Strategy Officer (CSO) and Chief Technology Officer (CTO) of Chemik Group, during his participation in the Future Energy Summit (FES) Iberia 2026.
“Last year we supplied 6 GW of products worldwide, which is no small figure. Overall, we have reached 40 GW globally,” Erdociain stated while outlining the company’s recent performance. He also noted that Chemik holds between 80% and 90% market share in Spain.
Building on this growth trajectory, the company presented two new technological solutions designed to enhance asset safety and reduce installation costs in solar PV projects, at a time when developers are seeking to maximise operational efficiency and ensure the bankability of projects.
The first innovation is TCS String, a solution designed to optimise string inverter installations by industrialising installation processes and modifying materials used in the system, with the goal of significantly reducing implementation costs.
“By industrialising more of the installation process and changing certain materials, we can achieve savings of 55% to 60% in string inverter installations,” Erdociain explained.
The second technology presented at the event was Chekarc, a system focused on the early detection of electrical arcs in PV strings — a phenomenon that can lead to operational failures or even fires if not identified in time.
“It can detect the arc within the string and isolate it so it remains contained. At the same time, it alerts operations and maintenance teams to verify what is actually happening,” Erdociain said during his presentation.
The system is customised for each project through a prior electrical analysis that allows it to differentiate between real arc faults and the electrical noise or harmonics generated by inverters, one of the main technical challenges in this type of detection.
“Electrical arcs are quite complex, and we analyse them for each project, distinguishing real arcs from the noise generated by inverters,” the Chemik executive added.
Erdociain emphasised that the company’s growth is closely linked to its ability to identify operational challenges faced by solar developers and provide technological solutions that add value to projects.
He explained that the company’s performance in recent years has been largely supported by strong client retention and the development of solutions tailored to the needs of each market.
“Ultimately, it comes down to offering solutions that build customer loyalty and identifying the problems developers face so we can provide answers,” he said.
In parallel, Chemik is advancing its international expansion strategy to sustain growth in the coming years. One of the most recent moves was the signing of a collaboration agreement with a local company in Japan, a market offering opportunities in solar plant repowering projects.
“Two weeks ago we were in Japan signing a partnership agreement with a local company. We have already supplied the first projects with our String Plus product. The client approved them, and now 17 additional projects are expected to follow,” Erdociain revealed.
The company also sees growth opportunities in Australia and the United States, where it is strengthening its presence through local partnerships and commercial initiatives.
“In Australia we appointed a Chemik country manager to closely follow both projects and market developments. We have already supplied 1.5 GW there, but growth has been slower than we want, and we believe this strategy will help accelerate it,” Erdociain explained.
In the United States, Chemik has established a partnership with a local company specialising in aluminium and copper cabling for the energy sector.
“You need to identify the markets where you can operate independently and those where you need local partners so your products can effectively reach the market and support growth,” the executive concluded.
