Thread: Power prices, gas prices- ouch or Solar perhaps?

We have two separate lots of solar panels on our house so two inverters ( German & Swedish ) One inverter had to be replaced after 3 years the other we had to replace in January this year ( about 10years old) The guy who came to replace it told me we would need to replace all the solar panels in the next 5 years as the efficiency of the panels & booth panels & inverters have a limited life . They don't tell you that when they sell you the systems.

Bet he is wrong! 10 plus years for almost all Solar panels. Every thing has a life span. Proof is your solar yield in a month by month over the years not some one wanting to sell you things.

Note some very cheap rubbish was imported a few years ago allegedly. Some studied in this link are 2008. Surprised you were not under a warranty for the 3 year replacement? SMA for example has "5-year manufacturer's" warranty which is often 10 years with just a little rejigging. I sold one second hand to put a Hybrid inverter at work which is still kicking on at 10 years old now.

I have a tenant in one of our sheds that wants a 200Kw solar system.

We are working through quotes,and other options at the moment.

I hope the panels and inverters last longer than 3 to 5 yrs?
Seems most we have been quoted have a 5yr warranty.

Looking at some with 25 years warranty? 10 year plus is normal for better quality panels.

Back on topic. "Five states face power uncertainty as AEMO warns of maximum load interruptions"

What a mess! Beside lights our vaccines are completely dependent on power security! That five state warning is right now and next few days!

Better warranties than 5 years on inverters.
What gear have they quoted you on?

This off one of the quotes,i cant get to the prefered quote at the moment.

System Size: Approx. 219.kW
Panel Make: Tier 1 Panels
Panel Model: 440 – 540W modules
Inverter Make: SolarEdge
DC Isolators: ZJBeny or Suntree
AC Isolators: Suntree, NHP or Nusainger

Up to 100Kw there are good rebates,so will probably be done in two stages,as it will be just under 200Kw.
Need room around the AC units,roof mounted fans,access to gutter clean,etc.

Ok, doesn't have a panel brand I see.
Solaredge stuff is good, I have that on my house. We are currently installing a 1.2Mw solaredge system on Coffs hospital, a lot of work.

We generally do all our over 100kw systems the same, install the first 99.9kw, claim STC'S, then do the remainder later on.
