Thread: 44 Solar panels fitted today

Not sure about the 60 watt panels as we only use 190 or 230W panels but if they work, all is good.

Did they go through best practise etc.

Like doing washing and ironing etc after sunset or when panels are not producing power. That way, when panels are producing you are getting 44c plus 6 cents credit during the day rather than power being generated being used as you go.

Check install that all panels are earthed and all that stuff.

Good work mate.

They are different style panels, they work better in partial shading and bad azimuth, earthing of all panels is not required yet and certainly is a joke, you need to earth the rail on non isolated inverters which pretty much anything over 3kw is, they hope to blanket rule to earth everything in the next as5033, idiots!

any idea of what the performance or efficencey for the pannels is after 25 years?

as far as earthing and such, up here in QLD where flooding is a real chance, which could easily mean being stranded on a metal roof top, would it not be wise to have an isolator or main on off switch on the roof????

I do realise you are in SA, the driest state in Oz...

I live in Qld and have solar panels and I bought a house that won't get flooded so I don't need a switch on the roof :-)

In SA both arrays must have isolators on the roof as well as at the control box.

Produced a lazy 38.93kWh today

ill ask some stupid ????

is it light or heat? does humidity change anything?

would the energy used to rotate the pannels on some sort of mech. to keep them in best angle to sun both long and lat, be overcome or out produced by the energy gained from doing so?

We get over 10.5 hours of useful light at the moment!!! He's loving it!

We are getting 5kW system fitted tomorrow on the shed roof with a SB5000TL which will hook into my LAN for monitoring just nicely

Living in Whyalla you would need to keep that red iron ore dust off the panels, when I worked down there you couldn't walk across the street after having a shower without the red dust settling on your hair, hope it's improved somewhat, regards Frank.

Had a bloke from Enviroment and Hertage round the other day and he reckons that it would take about 20 years to get the cost back (use about $1200/year) for an installation on my place, not only that but it is doubtful whether the panels and inverters would last that long anyway, so more replacement costs, is he right, Regards Frank.
