Since 2017, installers across the United Kingdom have deployed Tigo MLPE devices at more than 20,000 customer sites, with a sharp increase beginning in 2023. With nearly 1000 install sites in the second quarter of 2026 and almost 500 sites in July alone. More than 98% of all Tigo MLPE devices installed in the UK feature optimization. Due to the high incidence of shading, irregular roof elevations, and urban obstructions across the UK market, Tigo systems produce an average of 9% Reclaimed Energy. This results in a significant return on investment for UK homeowners with Tigo optimization.

“For our residential solar customers all across the United Kingdom, Tigo has consistently provided the absolute maximum value for solar system output, particularly because we do not have to overcomplicate our designs,” said Clark Gourlay, Electrical Installation Manager at Union Technical Services Ltd. “Granted, customers are not always certain about what Reclaimed Energy does for them, but once we can show the additional production via the EI App, it becomes quite convincing. We also appreciate the attention we get from the Tigo training and support team, who are basically never more than an email or quick phone call away.”

The GO Optimized ESS integrates the GO Battery with the Tigo EI Inverter, TS4 Flex MLPE optimization products, GO Junction for heat pump integration, and the Tigo Energy Intelligence (EI) platform, helping give installers a single, connected ecosystem that covers solar production, storage, e-mobility, and home heating. Installers deploying the GO Optimized ESS for the first time can benefit from the Tigo Green Glove program, which provides a professional system design review, puts technical experts on standby during installation, and creates a direct feedback loop with the Tigo team. Tigo Academy training further supports installer onboarding.

“Union Technical has very rapidly established itself as one of the strongest Tigo installers around the world, and I am happy to welcome them to the Advanced tier of the Tigo Loyalty Program,” said Mirko Bindi, Senior VP of Sales EMEA & MD Europe at Tigo Energy. “We firmly believe that solar must be a team sport between technology providers and the companies deploying the systems, which is why Tigo constantly works to expand installer relationships with programs like the training roadshow, Green Glove, and the Loyalty Program. Based on the feedback we have gotten in the UK, these initiatives move the needle for the whole solar industry here.”
