Off-Grid Estimator

Calculate solar off-grid system loads or perceived loads by entering information in the blanks. You may enter information about quantity, wattage, and number of hours of operation of each load per day. Make your way through the estimator by clicking on the equals button only for the loads you wish to calculate. When you have made it through all of your loads you may then estimate your load size at the bottom of this page.

The information you calculate on this page can be emailed to a design engineer along with other necessary site analysis information. If you are ready to start the consultation process see the info at the bottom of the page.
