The load is calculated by enumerating all appliances together with their power ratings and operational hours, thereafter adding these values to derive the total average energy demand in watt-hours or kilowatt-hour. . Batteries for autonomous systems are dimensioned to store energy generated by the array for utilization by the system loadsas needed. The overall rated battery capacity require. . Autonomy refers to the duration, in days, that a fully charged battery can sustain system loads without recharging from the photovoltaic array. Extended autonomy periods are empl. . The designated autonomy and maximum permissible depth of discharge (DOD)determine the overall battery capacity necessary for a specific system load. Extended p. . This MS Excel spreadsheet calculates the following: 1. Total Demand Load 2. Size of Solar Panel 3. Select Type of Connection of Solar Panel 4. Select Rating of Each Solar Panel 5. Energy f. [pdf]
Use our Off-Grid solar calculator tool below to estimate system size. Check out our video on off-grid sizing for details and more information on the design process. Steps to use the off-grid calculator: Enter your zip code *, and we'll look up the the sun hours in your area. *Must enter zip code to gather data.
Steps to use the off-grid calculator: Enter your zip code *, and we'll look up the the sun hours in your area. *Must enter zip code to gather data. How many Sun Hours a day do you average in the darkest month? We’ll start by using your winter low sun hours to size your PV array.
Below is a combination of multiple calculators that consider these variables and allow you to size the essential components for your off-grid solar system: The solar array. The battery bank. The solar charge controller. The power inverter. Simply follow the steps and instructions provided below.
The primary factor determining your off-grid system size is your Daily Energy Consumption, measured in Watt-hours (Wh) or kilowatt-hours (kWh). 1 kWh = 1,000 Wh. The higher your daily energy usage, the more solar panels and batteries you’ll require.

In Georgia, a solar panel installation would cost you between $2.55 and $3.55 per watt. That means a 5- to 6-kilowatt installation could run anywhere from $12,750 to $21,300.. In Georgia, a solar panel installation would cost you between $2.55 and $3.55 per watt. That means a 5- to 6-kilowatt installation could run anywhere from $12,750 to $21,300.. As of December 2024, the average solar panel cost in Georgia is $2.65/W. If you install a 5 kW system it will cost you between $11,250 to $15,220, with an average cost of $13,235.. You'll need to install a 11.91 kW solar panel system to cover the average electric bill in Georgia, which will cost you about $22,061 after the federal tax credit. [pdf]
