Show HN: Solar Panel Shade Simulator – Visualize How Shading Impacts PV Output

https://solar-shade-simulator.lovable.app

I built an interactive solar panel shade simulator that lets you click on individual solar cells to apply shade and instantly see how it affects power production at the cell, string, and system level.The goal is to make the often-confusing behavior of shaded solar panels intuitive—especially how string current is limited by the most-shaded cell, and how bypass diodes change the story.Why I...

You get similar ones from alibaba from around $175 : https://www.alibaba.com/product-detail/Fresh-Air-Ventilation...

I am looking at buying one of these and have had a look at similar (but not open-source) products available on Alibaba, e.g. https://www.alibaba.com/product-detail/Fresh-Air-Ventilation...

Prices there start at $150 + shipping.

Has anyone tested these?
