20+ years of solar energy experience, 80+ completed projects, a global vision from Konya to Romania
A journey that began in 2005 with a team of three engineers, transformed today into a leading company that has executed over 80 projects with a capacity exceeding 85 MW, now expanding into the European market.
The company was founded by Engineer Osman Çolaklıoğlu in Konya, central Turkey, a region with the highest solar radiation rates in the country. The company started as a small engineering workshop specializing in electrical system installations for industrial facilities, but the founder's early vision for transitioning to renewable energy made it adopt solar specialization before it became mainstream in Turkey.ÇAĞLAYAN ENERJİ® على يد المهندس عثمان تشولاكلي أوغلو (Osman Çolaklıoğlu) في قونيا بوسط تركيا، وهي منطقة تتمتع بأعلى معدلات الإشعاع الشمسي في البلاد. بدأت الشركة كورشة هندسية صغيرة متخصصة في تركيب الأنظمة الكهربائية للمنشآت الصناعية، لكن رؤية المؤسس المبكرة للتحول نحو الطاقة المتجددة جعلتها تتبنى التخصص الشمسي قبل أن يصبح تياراً رئيسياً في تركيا.
In the early years, the company focused on building a solid engineering base: carefully studying each site, selecting certified European components, and developing a strict installation methodology. This commitment to quality from day one explains our failure-free record in major projects.
Starting in 2018, our services expanded to include engineering consulting for major Turkish companies, then in 2019 we launched the R&D department. In 2020 we built the infrastructure for high and medium voltage networks, and in 2021 we made the strategic decision to focus fully on solar energy projects (GES) — a decision quickly confirmed by the wave of major projects that followed.
في عام 2026، نتخذ الخطوة الأهم في تاريخ الشركة: التوسع نحو السوق الأوروبي عبر تأسيس CAGLAYAN ENERGY S.R.L. في رومانيا. نحن صادقون مع شركائنا الجدد: لا نملك مشاريع منفذة في رومانيا بعد، لكننا نحمل معنا خبرة 20+ سنة من السوق التركي، ونفس معايير الجودة الأوروبية، ونفس الفريق الهندسي الخبير. شعارنا في هذه المرحلة الجديدة: «Global Vizyon, Yerel Güç» — رؤية عالمية، قوة محلية.
A clear vision and a measurable mission — this is what ensures that every project we execute serves a purpose greater than selling solar panels
We transform rooftops into a sustainable income source
We offer integrated solar energy solutions with European quality standards and an expert engineering team. We provide our clients with real energy independence.
Every decision at CAGLAYAN SOLAR ENERJİ is tested against these five values — they are the difference between us and competitors who offer the cheapest panels with the fastest installation
We use exclusively Austrian Fronius inverters and CE- and IEC-certified European components. We refuse cheap Chinese alternatives that offer illusory short-term savings and deteriorate quickly.
No hidden fees. Every price quote is detailed and includes materials, labor, installation, commissioning, and warranty. We clarify what you are buying and why, even if it means losing a deal.
Our team does not disappear after installation. We offer periodic maintenance, remote performance monitoring, and response within 48 hours throughout the 25-year warranty period and beyond.
We handle the project from the first idea to actual operation: 3D engineering design, procurement, installation, documentation, and grid connection. You get a working system, not just a set of panels.
We carry the name ÇAĞLAYAN ENERJİ® registered since 2005. Every project we execute protects this name or puts it at risk. Therefore, we treat every client as a future partner, not a single deal.
We do not just offer renewable energy, we select its components to last 25 actual years, not 5 years with weak remnants. Every ton of carbon we avoid today must be actually avoided, not just on paper.
From founding in Konya 2005 to international expansion in Romania 2026 — six milestones that made CAGLAYAN SOLAR ENERJİ what we know today
Founding of ÇAĞLAYAN ENERJİ® by engineer Osman Çolaklıoğlu in Konya, Turkey, as an engineering workshop specialized in industrial electrical systems.
Beginning of providing energy and engineering consulting services to major Turkish companies in the industry and agriculture sectors.
Launch of R&D department + development of energy sector software for performance monitoring and predictive fault analysis.
Installation of high and medium voltage distribution networks + consulting services for connecting major stations to the national distribution network.
Strategic focus on solar energy projects (GES) — a decisive move that led to executing 80+ projects in just 4 years.
Establishment of CAGLAYAN ENERGY S.R.L. in Romania — beginning of international expansion into the European market under the slogan «Global Vizyon, Yerel Güç».
Over 20+ years we built a network of trusted partners in Turkey — each specialized in a specific aspect of the solar energy project execution chain

"بدأت هذه الرحلة عام 2005 برؤية بسيطة: أن تكون الطاقة النظيفة في متناول كل منشأة في تركيا. رفضت منذ اليوم الأول التوجه السائد نحو استيراد منتجات رخيصة منخفضة الجودة، واخترت شراكات مع موردين معتمدين دولياً يضمنون أداءً يدوم 25 سنة فأكثر."
اليوم، بعد 80+ مشروع و85 ميغاواط، أفتخر بأن كل عميل من عملائنا يحصل على نفس الجودة التي وعدت بها في يومي الأول. والآن نحمل هذا الالتزام إلى السوق الروماني — نفس الفريق، نفس المعايير، نفس الوعد."
