All the power in my camper is provided by solar energy. I paid maybe $500 for the system, including a lithium ion battery. It will provide power for the next 25 years for two people, using computers all day long and plenty of bright lights at night.
Solar power is hella cheap. People need to stop whining.
It is cheap because manufacturing was subsidised by cheaper dirty coal-fired electricity. Solar panels today are essentially overpriced batteries that require years of time and sunshine to discharge. 10 years ago most solar panels barely returned 50% of the energy expended to make them. At least we seems to be getting close to the breakeven point.
P.S. I really doubt that the panel will last 25 years, and the battery is likely to go poof even sooner.
The battery is Lifepo4 chemistry with a good solar controller from electrodacus.com. I typically drain to about 65% so these are considered shallow cycles.
I think the battery will go for 15 years & the panels too. So 25 years was a bit of a stretch but 15 years electricity for $500 was pretty OK.
Solar energy really is cheap.
There are many parts of the world where it makes the most financial sense.
