Solar Monkey and Eturnity merge to form the European leader
in installer software

25 March 2026. Today, Solar Monkey and Eturnity announce their merger. Together, they
deliver software to more than 2,000 installers across 8+ European countries. Their
software provides the backbone for the full installer process, from design and sales to
installation and permitting. This enables installers to tackle the complexities of today’s
energy market and improve their cost competitiveness.
The merger brings together Solar Monkey’s software for intuitive design and sales with
Eturnity’s strength in end-to-end workflows and complex project engineering. The full
range of energy installations and related products will be supported. With a footprint
across 8 European countries, the new entity can provide superior economies of scale
and emerges as the leading installer software in Europe.
Both brands and products continue to operate in the foreseeable future. At the same
time, a stronger and more comprehensive range of software products will be
developed.
The new company is backed with fresh capital by investors including Klima (Spain),
Junction Growth Investors (Belgium), Eneco Ventures (Netherlands) and Helen
(Finland).
Addressing growing complexity of home electrification in a low-margin
market
The market is rapidly expanding beyond solar panels toward complete home
electrification systems. Installers are moving from single-product solar projects to
integrated energy systems including products like batteries, heat pumps, and dynamic
tariTs. This drastically increases the complexity of the installers’ jobs.
At the same time, the pressure on labour costs (which accounts to 60% of the total
cost) is mounting.
“Basically, all installers need to grasp this increasing complexity”, says Matthias Wiget,
CEO of Eturnity. “Installers can no longer compete without a strong software backbone
to streamline their increasingly complicated work. From lead to installation, every step
in the workflow needs to be digitised. That’s where the biggest gains are.”
Accelerating the path to clean, independent energy is more relevant
than ever
Both companies have always been passionate about sustainable energy, making solar
the world’s leading power supply. But there is more to it than clean energy and
preventing climate change. In today’s turbulent political climate, energy independence
is increasingly important. Locally produced sustainable energy reduces dependence on
imported fossil fuels and stabilises energy costs across Europe.
From two local industry peers to one merged leader
The founders of both companies have known each other for years through the European
solar industry. “We always shared respect for what the other team was building,” says
Jan Pieter Versluijs, founder of Solar Monkey. “By joining forces, we combine deep
market knowledge and complementary strengths across markets and products. That
allows us to innovate faster and build even better software for installers across
Europe.”
