Off-grid solar systems must be designed correctly in order to generate enough power throughout the year and have the necessary battery capacity to meet the installed locations electrical energy requirements or demand.
A backup generator or alternative back up power source may be necessary to supplement your electrical demand and recharge the batteries during times when the batteries are inadequately charged due to very bad weather patches or other unforeseen circumstances. We recommend that the size of the backup power source should be adequate to supply energy to your house and charge your batteries at the same time.

Daily watt-hour usage can normally be calculated from your utility bill over a time-period but may require more accurate usage pattern monitoring with energy metering data loggers.
