Hi Leasx.
If your business is open and running air-con in daylight hours, batteries won't be what changes the equation, the ever reducing costs of solar panels will be.

Yes, EPW supplies power to commercial/industrial clients, and yes, the uptake on their rooftops to date has been slower than in residential applications.

But you are looking at a solar and battery combination as a one unit phenomenon that will take one user off the grid.

What I am talking about is a change in the way that electricity is generated and stored at the tips of the tree branches by all users, rather than in the trunk as it is now.

Check out the software that Reposit power has developed. This allows a battery owner to sell back their electricity to the grid at times of peak demand.

It won't matter if the panels or batteries are physically owned or installed on the business' roof, the overall effect will be that end users of electricity will become both consumers and producers of electrons, traded using the grid.

If current electricity producers/retailers don't come to the party, you can be sure there will be a new company that will. And they won't have the old overheads to cover.

I'm not saying anything will happen overnight, but going back to my point about psychology of the investor, once people begin realising that this is coming in one shape or another, there won't be a single buyer of shares for any traditional power supplier/retailer.
