Solar Rebate Loss

I had a customer that has had their system for four years now and never been cleaned. I worked out they are missing out on one kilowat of power every day. Their buy back rate is $0.44/kW. So this works out that they are missing out on an average of $200 off their electricity bill each quarter!

That's a lot of money each year to be missing out on!

A bit extra money every month

Am I the only one that is always looking for ways to make a little extra money every month?

Would you Invest Money into Something to Help you Save Money?

I have been Cleaning Solar Panels for my Customers over the last 5 years, in Both Dubbo NSW and Gold Coast/Brisbane QLD.

The Systems are usually around 3 years old when a customer must start to recognize a significant enough difference to their bill to start investigating about what they have to do to help their System!

I would have thought if you Invested so much money into a way to save you in further money on your electricity costs that you would have read through the Owners Manual or Investigated further online as we all do these days, to find out how you can keep your system working for you to it's maximum?

So if I was to buy a 5Kw System approx 3-4 years ago and got it installed and just left it there, as this is what most of us do! say it cost me $8-10,000?
At $0.52 per Kw Rebate, I would be expecting Approx $3930 Savings off my Electricity every year?
Taking a bit under 3 years to pay this off!
Loosing up to 30% off that $3930 after 12 months = $2751 now taking a bit "Over" 3 years to Pay the System Off!
Year 3 starts and we loose another 30% Off = $1925
All this because we Did not want to spend how much to Clean and Maintain your Systems Panels?

So if we Take First Year = $3930 minus Second Year $2751 = $1179 Difference
Second Year = $2751 minus Third Year = $1925 = $826  Difference

Cost to get your System Cleaned is Average $7.50 per Panel ( This average is based on SolarCleaner Aust Prices)
5Kw System Approx 21 - 27 Panels = Average of 24

24 Panels x $7.50 = $180 every 6 months to Maintain a minimal Loss off $3930 Every Year if any at all!

So If customer was to Get their System installed and set up a Clean and Maintanence Program through SolarCleaner Aust
I would estimate something like this?

Year 1 - Return of $1965 in 6 months then a cost to clean of $180 = $1785
Year 1 - Return of $1965 in 2nd 6 months then a cost to clean of $180 = $1785
Year 2 -  Return of $1965 in 6 months then a cost to clean of $180 = $1785
Year 2 -  Return of $1965 in 2nd 6 months then a cost to clean of $180 = $1785
Year 3 -  Return of $1965 in 6 months then a cost to clean of $180 = $1785
Year 3 -  Return of $1965 in 2nd 6 months then a cost to clean of $180 = $1785

$10710 in Electricity Rebates - $1080 Maintenance Program = $9630

No Maintenance Program  Approx $8606 Back in Rebates over 3 years?? is it worth it?
