Designing an off-grid solar system has traditionally been a complex process involving detailed calculations to ensure the system can meet a household''s energy needs year-round. However, for the average Australian family, much of this complexity can be avoided by using a simplified approach based on established averages.
Lead Acid Sizing. 10 kWh x 2 (for 50% depth of discharge) x 1.2 (inefficiency factor) = 24 kWh Lithium Sizing. 10 kWh x 1.2 (for 80% depth of discharge) x 1.05 (inefficiency factor) = 12.6 kWh Battery capacity is specified in kWh or amp hours.
The amount you enter is the minimum recommended inverter size. Example: If you want to run a 50-watt LED light and a 1500-watt blow dryer at the same time, you would need a DC/AC inverter that is rated to handle more than 1,550 watts (1,500w + 50w = 1,550w peak watt usage).

This MS Excel spreadsheet calculates the following: Total Demand Load; Size of Solar Panel; Select Type of Connection of Solar Panel; Select Rating of Each Solar Panel; Energy from Solar Panel as per Daily Sun lights; Size Battery Bank; Select Type of connection of
Step 1: Calculate your load. Check all of the loads (home appliances) and record their power requirements. You need to make sure what devices are likely to be on simultaneously and calculate the total load (peak load). An off-grid solar system operates independently from the electrical grid, generating and storing enough energy to meet a

Grid-Tie Solar Calculator. This grid-tie solar calculator generates a Solar Electricity Analysis that will allow you work out how many solar panels you will need to create a theoretical ''carbon neutral'' building, where you sell surplus energy you make from your solar panels to the electricity utility company and then buy energy from the utilities when your system is not generating enough
Using the energy wisely when being generated will help minimise the size of the batteries such as using the washing machine when it is sunny with a solar pv system. By now you can see how much of a balancing act it is designing the best off-grid system. We recommend you use our Off-grid Sizing Calculator and return the results to us.

Input ALL electrical loads and appliances that will be powered by the solar and/or backed-up by batteries. To properly size the system, we need the maximum estimated daily usage for that electrical equipment year round. Most Off-Grid homes are designed with electrical loads in mind.
Electric heaters - Do not use solar power to run electric heaters for long periods of time. Electric heaters use up a huge amount of power (1200 watts for example) and a solar system to power them would cost too much. Use propane, natural gas, wood, solar air heating or solar hot water instead. Things like toasters and coffer makers use
