Is Solar Techno Alliance real or fake?

I've been hearing a lot about Solar Techno Alliance lately, and I'm wondering if it's a legitimate investment opportunity or just a scam. I've seen some claims that they're using blockchain technology to revolutionize the renewable energy sector, but I'm not sure if that's just hype or if there's any real substance behind it. Can you tell me more about Solar Techno Alliance and help me determine if it's worth investing in? I'd appreciate any insights or red flags you might be able to point out.
