Following our receipt of the allegations from Marianne Hunn (as reported by the ABC), a thorough investigation was performed by John Daly, the National Sales Manager for SunEnergy.
Marianne Hunn has consented and given permission for SunEnergy to disclose the following information regarding the performance and operation of her solar system.
Marianne had a 5.13kw system installed on 3 phase. From the first day of power generated (December 30th 2018) until the date of assessment (20th August 2020) it was found that the system had produced a total of 11647.7kw. This works out to be an average of 19.38kw a day. Her original proposal was estimated to be only 17.43kw a day meaning her system was performing better than originally calculated.
Below is the data from Marianne’s solar installation.
The above figures are from 2 winters and 1 summer in Adelaide over 601 days. It’s important to note that there is lower solar power production in winter. The difference between her savings per fortnight and solar repayments was only $0.73 per week. However, Marianne had in fact saved $1822.87 on her energy bills. She was also credited by her retailer with $1046.50 for power fed back into the grid. The total savings up the time of assessment from having the solar system installed was in fact $2869.36.
Marianne is on a feed-in-tariff of 14.44c per kw which is lower than the current available SA rate of up to 18c per kw. She was also on ‘bill smoothing’ with her energy retailer that had not been reviewed in over 18 months resulting in her paying more than required.
Mr & Mrs Hunn were only using 38% of their power with 62% being sold back to the grid. They were educated on how to maximise their energy usage to increase savings. Prior to having solar installed, Marianne and her husband were using 23kw a day of power. Their energy usage had also increased by approximately 20%.
A cash flow forecast was done based on all the data. Should energy prices stay at what they are at this time, over the next 20 years it is forecasted that Marianne will save an estimated $36,578 putting $70 each fortnight back into her budget.
Based on these findings, SunEnergy is confident that it has created a solution that works better than expected, plus it is a solution that matches the customers budget without almost any impact on their cashflow.
SunEnergy is now reviewing its legal rights with respect to the defamatory statements made and aired by the ABC.
