Can I use solar to reduce my electricity costs?

Using solar to save money on electricity is possible but not necessarily practical. First, you won’t get much benefit out of solar unless you also install a load supporting inverter or move some outlets over to be ran off of an inverter (both of which run off of battery power).

Then you’ll need to stop the converter/charger from recharging the battery so that the solar can so it’s job.

And then you’ll need to make sure you’re monitoring your battery’s state of charge in times that there isn’t enough sun.

I can’t imagine that by the time you invest in panels, installation supplies, and hardware that you’ll be able to recoup the cost.
