I love pv ... its the batteries / inverting / trouble shooting I hate, batteries will get old and bite you... I love all the craigslists free battery adds. Like I said .... loose just one cell out of the many and the system 50% impaired, Im done with that aspect of of it. Systems are getting better all the time agreed. Battery technology we have access to not much better than in the early 20’s. Lithium and other advanced batteries having the same issues fuel cells do – they catch fire….
However there is always a however isn’t there….. The Japanese are site installing little itty bityy 1kw fuel cells at residential locations to help with load on the grid – another one to watch
I can make electricity with a honda cheaper then I can buy it from helco these days - it really frosts me - Waiting for propane fired fuel cells for ten years now that is why I haven’t taken the cabin to more kw on the roof... I paid about 2.00 a watt and promptly watched it pass 4 as the europeans subsidized and forked up the market.
Being over here I took a couple of kw down and put them in storage rather then risk theft. I put them back up when I visit.
The boat is space and sound limited at 41 ft. 13 foot wide deck all working space... very little room for panels have them on the davits now - subject to big following seas being the downside. Lots of room by comparison for batteries down below – a good thing... One hasn’t lived until spending some time on a sailboat dependent on a ancient 7.5 kw diesel onan, rattles the filings right out ones teeth - grin
Using a 1 kw honda and solar to keep the radar,radios ,12 volt freezer and autopilot going underway these days
