At Over Easy Solar, we make solar simple. Introducing the VPV Unit—the world’s first fully prefabricated vertical solar solution. Complete with pre-assembled panels, cabling, and structure, it minimizes installation time and complexity. Thanks to our patented stacking design, transport is effortless and planning gets even easier. No matter your roof type, the VPV Unit delivers unmatched versatility and performance.

World`s first prefabricated solar system

Our wind-resistant system eliminates the need for heavy ballast and structural fastening, with a lightweight design that adds just 11 kg/sqm. Now, solar installations are possible on roofs with structural limitations that were previously unsuitable for solar.

No Need for Ballast or Fastening

Designed with ultimate user convenience in mind, these units offer a true plug-and-play experience, complemented by a clever integrated cable management system that promotes a clutter-free environment. The practical packaging of 33 units per pallet makes both upfront planning and ongoing logistics remarkably straightforward and manageable. Adding to this ease of use, the units can be assembled entirely without the need for any tools whatsoever, making deployment accessible to a wider range of personnel and significantly reducing setup complexity.

Blussuvoll skole, Trondheim

Over Easy Solar har utviklet en unik og fremtidsrettet løsning som åpner helt nye muligheter for solenergi på flate tak. Den vertikale, tosidige teknologien gir høy produksjon – spesielt i vinterhalvåret – og den lave vekten og enkle monteringen gjør installasjonen både effektiv og skånsom mot taket. Som installasjonspartner setter vi stor pris på hvor gjennomtenkt produktet er, og hvor profesjonelt teamet i Over Easy jobber. Dette er en teknologi vi tror mange bygningseiere vil få øynene opp for fremover.

Thor Christian Tuv, Daglig leder, Solenergi FUSen

Defensieweg 1, Odjik

We see the VPV Unit from Over Easy Solar as the perfect match for green rooftops, and we're excited about our partnership to bring this technology to the market. We have so far delivered Over Easy’s product to 13 installations in Netherlands, Germany and Belgium

Gjennom vår rammeavtale med Solcellespesialisten har vi fått installert solcelleanlegg med Over Easy Solar på to av våre bygg, ett i 2024 og ett i 2025. Vi har valgt løsningen på grunn av bæreevne og andre tekniske utfordringer som gjorde det vanskelig eller umulig å installere vanlige solcellepaneler. Vi ser særlig fordeler med løsningen med tanke på lav vekt, og ikke minst vedlikehold av flate tak der vi er usikker på levetiden til takmembranen.

Working with Over Easy Solar is always professional, efficient, and collaborative. Their vertical solar solution impresses both technically and visually – especially on gravel and green roofs, where the system's added value becomes particularly evident. Most recently, we completed another installation on a gravel roof in Romandy – the first of its kind in the region and already our fifth project with Over Easy Solar in Switzerland. We value Over Easy’s innovative approach and look forward to realising further sustainable projects together.

Aker Tech House, Fornebu

Over Easy Solar leverer teknologi vi ønsker å løfte frem i Aker Tech House – innovativ og fremtidsrettet. Deres vertikale solcelleløsning gir god ytelse året rundt, samtidig som vekstvilkår for det grønne taket blir ivaretatt.  Installasjonen ble gjennomført raskt og ryddig. For oss handler bærekraft også om innovasjon og nytenkning, og her er Over Easy Solar et veldig godt eksempel.»

Håkon Øiseth / teknisk konsulent, Fornebuporten drift

Ullevaal Stadion, Oslo

Som Norges nasjonalarena har vi høye ambisjoner – også når det gjelder bærekraft. Med Over Easy Solar har vi fått en innovativ solenergiløsning som ikke bare passer vårt tak, men som også setter verdensrekord med største vertikale solcelleinstallasjon på tak. Installasjonen på Ullevaal Stadion gir høy ytelse gjennom hele året, spesielt i vintermånedene, og den lave vekten og tilgjengeligheten gjør vedlikehold enkelt.
