Solar export value in dollars
We’ve taken the energy you exported in kWh (sourced from your energy company) and multiplied it by the regulated, recommended, or average FiT offered in your state.
Solar energy consumed within your home in dollars
Taking the amount of sun that fell on your area, or ‘solar radiation’, in kWh, and your solar system size, we have projected how much energy your solar system produced within the given period.
We have subtracted the amount of energy you exported to the grid (in KWh) and then multiplied the remainder by the reference rate in your area (single or anytime rates, using the regulated Victorian Default Offer, Default Market Offers in NSW, South East Qld and SA, and published rates in North Qld, ACT and Tasmania).
We have assumed the system is optimally installed (facing North at a 22 degree tilt with no shading) and sustains an average amount of energy loss.
Total value of your solar system in dollars
Calculated by adding together the solar energy consumed within your home in dollars and solar export value in dollars for given period.
How much you could save by using more solar energy
The difference between the solar energy consumed within your home in dollars and our calculation of the value of how much solar energy an energy efficient home could optimally consume (at Victorian Default Offer usage rates, single or anytime rate).
Sun compared to normal
This is the amount of sun, or ‘solar radiation’, that has fallen on your area this month in kWh. This is compared to the long-term average of solar radiation in your area. The areas we use for the data are based on available weather data.
Lump of coal
Calculated doing a visual assessment of the lump of coal Scott Morrison brought into Parliament in February 2017, which is estimated at around 400g (assumed brown coal, 400g is equal to around 1kWh of usable energy), which contains 350g of CO2 emissions if burnt.
Solar system down or ‘flatline’ days
Days when your solar system exported an abnormally low amount of energy to the grid.
How far your solar savings could take you in an electric car
Using the average cost of electricity in Australia ($0.25 per kWh) and the typical efficiency of an electric car (18.75kWh per 100km) we know that for every $4.68 your solar system saves you, you could travel 100kms in an electric car. So we divide your solar savings by 4.68, then multiply the result by 100 to find the distance.
