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.

This is my complete current set up and if you are running code I have recently written know that it is solar powered JavaScript!

Nice black & white kiwi curtains! Is that a hand built plywood dingy?!

@Dominic

@nanomonkey thank you. not just handmade, but also folding! It collapses to the size of a large surfboard and stows on flat(ish) on the deck. That's important when you only have a 7.8 meter long boat. It's okay to tow the dinghy short distances or in settled weather, but it's noisy (slapping against waves) and if it flips over, you have a big problem.

Are you using a 12 V regulator (LM7812) or buck converter prior to your LED strips, or is it fine with the 14.4V of the LiPO4 when fully charged?

@Dominic

@nanomonkey haha, I doubt you'd do very well selling something as "12v" if you didn't expect people to plug it into a car cigarette lighter! no I don't use anything, and it seems fine!

@nanomonkey

That's what I expected, an alternator can output quite a bit more than 12v. Still, I've burned up quite a few LED's running high current through them, and everything I googled suggested a regulator when used with a car battery. They probably dereg them a bit with the internal current limiting resistors so that they can handle some abuse.

Good to know.

Re: %16+4FpAAf

I lost one laptop with a similar wired up adapter, and switched to a car-laptop-adapter as mentioned my solar setup. I have fried several adapters, but no laptops. Luckily, they are much cheaper than laptops.

@Hiure welcome to secure scuttlebutt!

Your house is beautiful!

Haha, I noticed I have exactly the same charge controller on my boat
