Revolutionary ‘Super Solar Panel’ Generates 120 kW of Clean Energy in Space
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: A powerful ‘super solar panel’ called IROSA is being tested 400 km above Earth, generating 120 kilowatts of electrical power for the International Space Station, promising cleaner and more efficient energy for future space missions.
📈 One key stat: The new solar system can generate 120 kilowatts of combined power output, enabling the International Space Station to operate at full capacity while supporting expanded space operations.
💬 One key quote: “CEO of Redwire, Peter Cannito, is convinced that the ROSA-powered IROSA system will ensure sustained human activities in space.”
1️⃣ The big picture: A revolutionary solar power system named IROSA (ISS Roll-Out Solar Array) is currently being tested 400 kilometers above Earth. Developed by Redwire Corporation in partnership with Boeing’s Spectrolab, this ‘super solar panel’ can generate an impressive 120 kilowatts of electricity for the International Space Station. The 4th pair of solar wings was delivered in early 2025 and is now undergoing testing in extreme space conditions. IROSA uses lightweight materials that provide excellent performance with lower launch mass, making it an ideal power solution for expanding space operations.
2️⃣ Why is this good news: This solar technology represents a major advancement in powering space missions sustainably. The lightweight design reduces launch costs while maximizing power generation, helping extend the capabilities of the International Space Station. ROSA technology has already proven successful in other NASA missions and will likely become the foundation for powering future lunar bases and interplanetary travel. With $35 million invested in the latest wing pair, this technology establishes crucial power infrastructure for the growing commercial space industry. Clean, reliable energy generation in space removes a significant barrier to long-term human presence beyond Earth.
3️⃣ What’s next: The 4th pair of IROSA wings is currently undergoing testing in extreme space conditions. A resupply mission is planned for late 2025 or early 2026 to support ongoing operations. The technology aims to power future space habitats, lunar bases, and interplanetary missions as humanity expands its presence beyond Earth.
