Time to document the latest state of my solar setup.
Fristly, panel can be rotated and pivoted towards the sun. I get way more power this way, plus if it's horizontal seagulls will poop on it. It's a 160 watt panel I brought it a 2 years ago for $200.
Here is how the panel mount works. Aliminium tubes and a strap.
That goes to the mppt charge controller and batteries. Charge controller was second hand from someone who was upgrading their system, $100.
200 amp hours on lifepo4 battery this was a recent aquisition, and a great deal at $340. Currently set up in the location so I can check the voltage easily.
Laptop powered though 12v car adapter. $40. I also have 220v inverter but it's less efficient.
Lights from led strips, 5m for $15 switches $1 each.
It wouldn't be honest to leave out the engine although it's primarily for propulsion some times it gets used to top up the battery if it's been cloudy for a few days. Mostly there is more that enough sun, even in winter.
