If a box has a yellow background you can manually change the figure. It may have a pre-populated amount which is a general assumption that is changeable. If the box has a black background the figure that appears has been automatically calculated.
How to use the SPEC
There are 7 sections (left to right and top to bottom):
Some boxes require input whilst others automatically re-calculate:
If a box has a yellow background you can manually change the figure. It may have a pre-populated value which is a general assumption that is changeable.
Section 1: Power Consumption Data
From the drop down menu select battery voltage - 12V, 24V, 36V or 48V. Then enter either watts (column 1) OR Amps (Column 2) of items that will consume power plus the daily hours the item will generally be used (column 3). Column 5 lets you select whether the item is used day and night, just day or just night time. This section is pre-populated with some example data that should be checked and modified by the user for their specific needs.
Section 2: PV & Battery Performance Data
This section is pre-populated using real equipment data. The data, particularly the battery performance data should be checked and modified by the user if necessary.
Section 3: PV Solar Sizing Calculations
This section automatically calculates the required PV solar system size based on data in sections 1 and 2.
Section 4: Battery Sizing Calculations
This section automatically calculates the required battery capacity based on data in sections 1 and 2.
Section 5: Select Location and Season
This section allows you to choose a location and season from the drop down menu. This may be a regular travel destination or area where you will use the solar power the most e.g. Tropical North Queensland in Australia’s winter (dry season up north). Once chosen, the location on the map will display the peak solar panel power, the solar charge controller capacity and the battery capacity required for that location.
Note: The map shows annual solar radiation levels from lowest (dark blue) to highest (red) across Australia. (Source: http://www.energyfutures.qld.gov.au/solar.cfm)
Section 6: Calculation Results
This section displays your solar power system component requirements based on the data entered.
Section 7: Current/Proposed system
Since the calculation results in section 6 are only a guide, this section gives you the opportunity to choose a smaller system. You just need to enter your current/proposed panel wattage and battery Ah. The automatic calculations then display how long you can be independent without mains power based on the amount/size of panels you have/propose and the battery capacity you have/propose.
Only available on desktop.
If you have difficulty using the SPEC on an Apple Mac then try an alternate web browser (Chrome or FireFox). We are in the process of sourcing an alternate hosting platform to resolve the formatting issues on some PCs.
The calculator takes into account the power consumption you use in your caravan/RV and your travel destinations.

What is a PV System?
A Photo-Voltaic (PV) system is the solar panels together with the solar charge controller.
