The costs just don't make sense to me given you can only produce a 'maximum' amount of solar power per year and thus will only have a theoretical max savings that might only amount to anywhere between $100-400/year depending on size and system, and some of the plug-in solar systems I've seen have been running upwards of $3000+.

I know I can't justify spending $3k upfront to only offset $25/month at best. I'd rather just turn off a few lights and stop paying for Netflix.

It seems like a large cost for not a lot of power offset that's also unusable when the power goes out (since you can't run untied from the grid).
