for the moment that is what we recommend as well. Its still in the early adopter stage. They do have advantages due to lithiums acceptance of higher current for charging and discharging. So for an off grid scenario you can massively oversize the solar array due to cheap solar panels and get it all in with a relatively small battery bank. Lead's rate of charge/discharge is more fixed so you would have to double the bank size to equal the charge rate which lowers the cost difference. There are also some problems in our area due to Lithium's poor cold charging characteristics. I like them. I will like them more in 5 years...

Bottom line here is I just don't see the need for so much storage or power generation.  You just need to keep a few diode lights on and keep your laptop charged up and a fridge running.  How much power does that really take?
