Step 6 - Add Batteries

From SolarPneumaticHybrid

I probably won't do this until May 2011, but hopefully I will be able to do it sooner. What I can guess at this point, is that if you already have batteries, and you don't charge them from the grid as an emergency backup, and you only use them to store surplus energy, don't add more if your solar panels never manage to fully charge them. Instead of adding more batteries you should add more solar panels if your existing batteries are never fully charged.
