Solar panel upgrade / book recommendation

[GeraldTheBonzai]

Hi,
Want to recommend a book. https://www.amazon.co.uk/dp/B0BT7DZTN1? ... M19KZ9VSWK

Off Grid Solar Power Simplified: For Rvs, Vans, Cabins, Boats and Tiny Homes by Nick Seghers.

Absolutely packed with useful information if you have an off grid solar setup.

I'm in the process of adding some more panels and generally giving my emergency power setup an overhaul. Issue I had (now fixed) is that the panels I had are discontinued so had to find the closest match, whilst understanding the impact of adding more in series. Book has been really helpful, as well as other things like cable gauge calculations. Definitely worth it if you need to tinker with solar stuff, or just build a setup.
