This is the amount of energy you are going to be producing using your Solar PV system. This can work for you or only slightly for you if you are not careful. You have to keep in mind that in most places, they apply a principle of ‘Net Metering’. What that means is that your utility company has to buy any excess energy produced by your panels.
Now why would that be so bad?
For the very simple reason that the price at which you buy electricity from the grid is not at the same price as when you sell the electricity produced by your panels. The price being larger for the former than latter. So sizing the system is key unless you want to oversize it for off-grid usage.
You don’t want to produce huge excesses of energy – this will yield poor economic metrics and make your investment worth lesser in terms of Return on Investment (ROI) and leads you to a higher Payback Time (PBT).
