Global Sun Hub - Independent solar system calculator and equipment database

Hi Product Hunt! I’m Serhii Bereshchuk, the maker of Global Sun Hub. I built this because I realized that for most homeowners, going solar is a "black box." When you start looking into it, you’re usually met with aggressive sales agents, confusing quotes, and a lack of transparent data. It’s a huge investment to make without having the full technical picture. Global Sun Hub is designed to give the power back to the homeowner. We don’t sell panels and we don’t take commissions from installers. We just provide the data and the tools you need to walk into a meeting with an installer knowing exactly what you need. What you can do with it today: Solar Quiz: Get a custom system recommendation (size, panels, battery) based on your actual energy needs. Solar Roof Calculator: Help you to fit solar panels on your roof. Technical Database: Browse 5,900+ solar panels and inverters with deep engineering specs. Comparison Tool: Compare hardware side-by-side to see which technology (TOPCon, HJT, etc.) actually fits your roof and budget. No Signups: I wanted this to be as frictionless as possible. You can get a full PDF report without even creating an account. I’d love to hear your feedback on the calculator accuracy or if there are any specific features you'd like to see added to my tools! I'll be here all day to answer your questions. Thanks for the support! 🚀
