Who We Are
Learn moreAn Arabic renewable energy platform
Najdeah exists to turn sustainable energy from an idea into action. We provide the tools, the projects and the knowledge that let an engineer design a plant, price it and hand it over with confidence, instead of starting from a blank page.
It is led by engineer Nouraldeen Najdawi, with more than nine years designing and delivering solar projects across Saudi Arabia, the Gulf and Jordan. Every file in the store came out of a real project he worked on.

What Engineers Say
Great course. Very easy to follow and understand. I learned a lot through this course. No matter you are a beginner or experienced, this course will teach you everything you want to learn regarding solar energy system design and installation.
The content is well organised and the explanation is clear and to the point. It covers the practical side of the design, not only the theory, which is what I was looking for.
Very useful material for anyone working on solar plant design. The examples are taken from real projects and that makes a big difference.

Frequently Asked Questions
What happens after I pay?
The download appears in your account immediately and a link is emailed to you. Nothing is posted and there is no approval step.
Are the files really editable?
Yes. Drawings are AutoCAD, calculators and models are Excel with the formulas left in, documents are Word, and the simulation is a PVsyst file. Nothing is flattened to a locked PDF.
Which standards do these follow?
The design work is written against IEC and NEC. The design guide also covers the Saudi code and the requirements that come up across the Middle East, with worked examples.
Can I use them on a client project?
Each file is licensed for use by the person who bought it, including on your own commercial work. Reselling the files or passing them on as your own product is not covered.
