Solar Panel Sizing Basis

As i earlier mentioned that i shall install 1260 watt solar panels. Now its the time to show what were the basis of calculations. I have used a smart on-line solar panel system sizing calculator. The link is at the end of this post. Click on the photos to make them bigger.

Here is the stepwise sequence of load calculation activities:

STEP-1:  MONTHLY POWER CONSUMPTION CALCULATION

STEP-2: SOLAR PANEL SIZING

In this step we shall calculate the number of solar panels required based on the energy consumed by the electrical appliances in Step-1.

STEP-3: MPPT SOLAR CHARGER SIZING

I have already purchased 150DC, 45Amp charge controller.

STEP-4: BATTERY BANK SIZING

I have already purchased two batteries 12VDC 220AH.
