Solar power Archive
Maybe you have also wondered how much power do solar panels generate on a cloudy day compared to the clear sky? Other than the location on earth this is also a huge factor in overall performance. I had the same questions myself. So I tested my solar panel. I included my location on earth and time
This is a small follow up post for my main post (go read that post also after this post) about CMTP02 type of solar charger controller. Turned out that 5 amper version has actually much different content (-5a after model name refers to a maximum of 5 amperes charging current). It’s not actually a surprise since it handles much
Here is a simple solution to align and fixate cells while tabbing solar cells together using common tile spacers. This is very good because I can focus on soldering cells instead how they are aligned and fixed.
I want to share inside look at cheap Chinese solar charge controller CMTP02 (CMTP-02). I have a 30A (charging current) variant, but it has also 5A, 10A, 15A, 20A versions. It should be a PWM controller. Maybe even not that (like Didier pointed out in the comments section). I have not learned all the terminology regarding
