Calculating Your SavingsFind out how much your home or business can save on the cost of energy by installing solar.
How Much Can Solar Save You?
Unless you are planning on installing a solar system to save the environment you need to look at the financials to see if they stack up. With power prices increasing the chances are that solar will be a great investment. In Queensland the solar bonus scheme is a net metered scheme which means that only the excess electricity that you produce if fed back to the grid and the primary source of power for your home during the day is solar. This means that anything you use during the day will be power 100% free of charge by the solar. The savings that you make each quarter will vary according to a number of factors including the weather, how much power you using during the day, what appliances you are using, how much you are paying per kWh from the grid, the value of the power being sold to the grid and most importantly the size of the solar system you have. This table demonstrates how much the average person using 70% of the solar and exporting 30% would save on power over the next 10 years.
Solar energy has to be utilized correctly to pay full dividends for businesses and households.
What does that mean? Traditionally, when installing and using solar, we would only save energy when we use it during the day, as solar does not work at night. This means that we need to import electricity from the grid if we need extra energy or export it when our solar system is producing more than we use. But nowadays we have the option of adding storage and extending the benefits of solar energy savings into the evening and night. To illustrate this, let’s use an example: Below is a snapshot of the system energy flow and load energy flow of a 5kW system installed N-NW, in Emerald QLD. We can see the solar production and the grid energy flow for the 27-8-16. We can see that the solar production covers ~60-70% of the load. There is a baseline of ~1kW throughout the day and peak in the morning for ~2h and occasional peaks during the day. OFF SET LOAD: It is important to note the solar will only offset what is under the solar production curve and under the blue curve, marked with green rectangles. BUY FROM THE GRID: The load that exceeds the solar will be purchased from the grid, marked with red rectangles EXPORT TO THE GRID: Pretty much everything that is not green and not red. This is the type of solar system that would greatly benefit from additional battery storage. Batteries would be able to capture the excess energy to be reused later in the day and at night. This makes sense as the purchased energy costs ~25c/kWh and the exported electricity is only worth 6-7c/kWh.
