Solar analysis projection to 2024

Postby Kalani4321 » Mon Oct 21, 2013 1:27 pm

Hello Energy experts, would anyone have a spreadsheet that will allow me to input current system size, 12 months of historic usage (commencing in 2011) and generation data, current consumption and generation rates and allow me to project anticipated revenue and costs, including system degradation until end of 2024?

I installed a system, in Victoria, during mid 2011 while the Premium Feed In Tariff (PFIT) scheme was available and I received the tariff for 12 months until the retailer claimed that they had made a mistake updating the distributors database and now they want to bump me off the scheme. Obviously I paid a premium for my system during the PFIT timeframe and to be bumped off the scheme after only twelve months leaves me wearing an extremely high capital cost of the system and substantial loss of revenue until the end of the PFIT scheme which is 2024.

Any assistance will be greatly appreciated as I am up against a wall of bureaucrats doing their well rehearsed best to avoid the issue. :evil:

Check the http://www.DPI.vic.gov.au which scheme you are entitled to.
Having said that, the dates will refer to when a system was not only installed but all the paperwork had been completed and submitted as well. check that all out first. ;)

Sorry, it changed it's now to :-

Kalani4321, I have access to online software for calculating costings up to 25yrs from installation. I could enter all your information in and send you a report. You must be aware though the program carries a disclaimer regarding accuracy so court use would not be possible but you would have some information to help out. I gather you want find out difference if you were on one scheme as to the other.

Thanks davidg for your kind pointer, however I was really looking for a spreadsheet, that I have seen used by companies selling solar systems, which allows me to plug in the tariff, peak and off-peak rates and then project costs/revenue over a period of time. This also takes into account the degradation of panels over a period of time.
I am fully aware of the dates associated with the various schemes and my system was installed and accepted, with all the paperwork completed and submitted into the PFiT scheme, however now the retailer claims to have updated the distributors database incorrectly at the time of installation, and they now want to bump us off the scheme. Quite unbelievable I agree. That is why I need the spreadsheet mentioned above to mount a case with these people.
The additional frustration, as you have realised with the multiple URLs, is finding the latest Government department who is administering these schemes.
Do you know of anyone who might have access to this style of spreadsheet?

If you know your FiTs, what you pay for eletricity, and expected decline of PV output etc, it would be pretty easy to produce your own I think.

Hello Gordon, yes it would however it would also be helpful to use something that is used within the industry to add independence to the numbers. Do you know of anything that exists?

I dont know of anything personally, but if you show how you arrived at your figures, and use generally accepted/published data for cost per kWh, FiTs, panel degradation etc, there shouldnt be any bias/independence issues.

The reason I asked was because the applicable paperwork had to submitted by If I remember correctly September 30 to eligible, The last one I did under that scheme was for a Sparky friend, I/we put his paperwork in on September 29 for the PFIT.

I don't know anyone that provides spreadsheets for that, they build them (I did), I never did one that projected that far out.

Hi DavidG, thanks for the feedback and your recollection is spot on. My paperwork was lodged in August 2011. It's quite alarming that they can expel you from the scheme due to an error with the retailer, despite all paperwork being lodged and confirmed as received and processed. Does your spreadsheet still exist?

Not as it was, and with respect I would not provide it anyway, sorry

Now the current iteration has changed suit now, I don't use it as sales tool never have, I always believed and still do that real value in a PV system is in the saving that can be achieved by having the system, the SFIT(< I'm on this one), PFIT, TFIT were bonuses since they were offered it makes sense to claim them. I chose the SFIT at the time because there was almost no size limit well 100kw's.

Now I believe the real value is in hybrid, I promote this because it offers savings, it does take time to get the full ROI out of it but with a FIT of just .08c or even no FIT you can still make it pay it's own cost overtime not to mention essentially no blackouts, battery bank/pack size dependent.

Got to be worth considering and can be retro-fitted to any domestic and most commercial electrical systems with or without a renewable energy system. I know this because I not only install/design them I also live on a decent sized system as well. and run 2 houses from it.

No it's not cheap to do, good solutions never are unfortunately.
