Re: Going Solar...the best solution for Mars.
Is Making Your Own Solar Panels Worth It?
You can buy a stack of standalone solar cells on Amazon for around $15. which in turn generates an electrical current. 60 of these cells adds up to a 400 watt solar panel, which can provide enough electricity to power small devices and appliances in ideal conditions.

How Batteries Can Unlock the Full Value of Your Solar Panels
Modern lithium batteries are temperamental to heat and cold, but if they are kept under stable conditions, they hold up much better over the long term than the flooded lead acid batteries of generations past.
Fishman said she's been using batteries with her 2.4-kilowatt home solar system for over a decade. She opted to install more batteries rather than double or triple the amount of panels.
"They're still going strong after 13 years. We don't have any degradation on the batteries," she said.
According to FindEnergy.com, as a rule of thumb you should expect to pay around $1,000 per kilowatt-hour of a battery's capacity.
You can find batteries from as little as a few hundred bucks on up to $15,000 per battery. The average amount spent on batteries is in the top half of that range. Fortunately some of this cost can be offset by a 30% federal tax credit and other incentives.
