SOLTIGUA SRL

Their core work

Soltigua is an Italian SME that designs and manufactures concentrating solar collectors and solar thermal systems. Their core business centers on solar boilers and parabolic trough collectors used in concentrated solar power (CSP) plants and district heating networks. They bring hardware expertise to EU consortia — supplying and optimizing solar thermal equipment for both power generation and heating/cooling applications. Their work spans from improving CSP plant efficiency and reducing water consumption to deploying solar thermal solutions in smart district energy systems.

What they specialise in

How they've shifted over time

Soltigua's early H2020 work (2015-2018) focused squarely on concentrated solar power — improving CSP plant efficiency, extending the lifetime of CSP materials, and reducing water consumption in solar mirror cleaning and cooling. From 2019 onward, their focus shifted toward district-level energy systems, smart city integration, and renewable heating/cooling networks. This evolution suggests a company moving from component-level CSP optimization toward integrated urban energy solutions where their solar thermal hardware serves a broader system.

Soltigua is transitioning from pure CSP hardware toward integrated solar thermal solutions for urban district energy systems, making them increasingly relevant for smart city and decarbonization projects.

How they like to work

Soltigua primarily operates as a technology partner, joining consortia (5 out of 6 projects) rather than leading them. They coordinated one project (Re-Deploy), which was also their largest single grant (EUR 2M), indicating they can lead when the topic aligns directly with their core product. With 67 unique partners across 14 countries, they maintain a broad European network rather than relying on a small circle of repeat collaborators.

Soltigua has built a wide network of 67 unique consortium partners spanning 14 countries, indicating strong European reach for a small Italian SME. Their partnerships bridge the CSP research community and the district energy sector.

What sets them apart

Soltigua occupies a rare niche as an SME that actually manufactures concentrating solar collectors — most H2020 solar thermal participants are research institutes or large utilities. This means they bring real hardware, production capability, and commercial deployment experience to consortia. Their evolution from CSP into district heating makes them a versatile partner for any project needing solar thermal equipment with a pathway to market.

Highlights from their portfolio

• Re-Deploy
  Their only coordinated project and largest grant (EUR 2M), developing redeployable solar boilers for ESCO-type commercial sales — directly tied to their core product line.
• WEDISTRICT
  Their most recent and second-largest project (EUR 1.5M), marking their strategic shift into smart renewable district heating and cooling.
• MinWaterCSP
  Addressed a critical operational challenge in CSP — water scarcity — with specific solutions for dry/hybrid cooling and mirror cleaning, showcasing deep technical specialization.
