Solar calculator and system design tools

NEW! - Try our new solar quoting system. Simply enter some basic details, then based on solar power equipment choices you select and your location, detailed performance information and graphs will be calculated. ">Try it out here!

Our solar calculator and system builder can help you calculate your solar energy needs. However, if you'd like free, expert and no-obligation advice regarding a solution tailored to your home or business, please call our friendly team today on 133-SUN

Historical weather and climate data

To optimise the performance of your system, we need to know the what the weather is like in the area where the system will be installed. Please complete the 3 steps below to begin designing your renewable energy system

Step 1: Enter your country followed by a postcode, town or suburb name, then click "search". A map of your general area will then appear below (it may take a few seconds to load):

Step 2: At this stage weather data from the nearest weather station should be displayed below. You can scroll down to view the climate data, or click on the red markers on the map to view summary information. (It may take a few seconds to load).

PLEASE NOTE: If no data is appearing in the calculator below, you will need to click one of the red markers above to select a weather station close to your chosen location

• Solar Irradiation & Wind Speed
• Air and Ground Temperature
• Humidity and Air Pressure

Step 3: Once you have chosen your nearest (or most appropriate) weather station, you can proceed to design your own wind or solar power system. Choose the type of renewable energy system you wish to design.

	Are you connected to the electricity grid? (Australia) Use our grid connected system calculator to calculate the electricity savings and greenhouse gas emission reductions.
	Do you need electricity in places where it is not available? Try our Stand Alone Power Systems (SAPS) calculator to determine your remote power requirements. Suitable for remote houses, marine, campers, campervans, caravans, 4 x 4 and off-road vehicles, etc.
	Online DC cable sizing calculator, use this tool to determine thickness of cable required for your system. The right sized cable will give you the best efficiency!
	Solar pumping calculator - Use this tool to determine what kind of solar pump you'll need, how much solar power is required, and how much water will be delivered.
