How to determine the impact of Solar on your Home

1) All energy companies base your energy bill off of the number of KWh that you consume

each month and multiply it by the cost for each KWh. The cost per KWh can be

calculated by dividing your total bill ($) by the total number of KWh consumed for the

month.

2) You can determine the number of KWh you consume each month by dividing your energy

bill by your cost per KWh.

3) Calculate your total annual KWh consumption or estimate it by multiplying it by 12.

4) Compare your annual KWh consumption to a package number based on the KWh

production of each system. Please be aware that there is a difference in solar production

based on the system being installed on the S, E, or W side of your home.

Example:

My home consumes and annual average of 2000 KWh per month which is around 24,000 KWh

per year at a cost of $0.15/KWh. The available space on my roof is 300 SF and is oriented to

the South.

I choose solar package APS-PV-3600 as the best option for my home based on the square

footage. This system will produce around 4,391 KW in the year which is 18% of my homes

energy consumption.
