The hazards of Solar Installation
Aug 22nd, 2019 at 1:53pm
 
Solar panels are reasonable safe and reliable to install and can pay off but batteries are jolly expensive.

So forget about recharging your tesla overnite from the 7 or so batteries you would need.





Don’t Become A Lost Sheep In A Field Of Wolves:. The Top 7 Mistakes People Make When Buying Solar Systems
By Finn Peacock – Chartered Electrical Engineer, Ex-CSIRO, Founder of SolarQuotes

Don’t wait for batteries to drop in price before buying solar
Despite the hype about solar battery storage, any honest solar installer will give you the same advice: Batteries will not pay for themselves in 2019.

At the moment, a Tesla Powerwall battery system will cost you around $15,000 to install, and will take about 15 years to pay back. The unit is warranted to last 10 years.
You do the maths.

Unfortunately, all the hype in the mainstream media about batteries has made people question the viability of solar without batteries – to the extent that people are waiting for ‘affordable batteries’ before they invest in solar. But even though the cost of solar battery storage is projected to decline year-over-year, it makes no sense to wait to get solar.

Every day you don’t have solar is another day you do have to pay high electricity bills. A well designed solar system without batteries can give you tiny bills.

Waiting 2, 3 or 4 years for batteries to become affordable means another 2, 3 or 4 years of high bills. One day, batteries will make lots of sense – and when that day comes they can easily be added to any existing solar system using a method called AC coupling.

So don’t lose years of savings waiting for cheap batteries to arrive.

Consider going solar now – with the knowledge that you can easily retrofit batteries later when they will pay for themselves – not before.

Get the solar asap, the money that can be saved can go towards batteries in the future, if they come up with anything worthwhile and proven, the solar panels will go at least 20yrs.

Yes so long as you have a north facing roof and don't get one of those giant hail storms.

Solar panels can catch fire if they develop an electrical hot spot.

But otherwise quite good just so long as the Govt doesn't stop subsidizing them.

But you need to be very brave or silly to try to live off the grid with them. Or like candles.

I wouldn't live off the grid and I wouldn't buy batteries unless I had to, the solar panels are good value as any growing number of solar panel owners will tell you, free electricity and no moving parts.

Just so long as the Govt keeps subsidizing them. This could change at any time.

Actually solar home installations are a nuisance for the power companies as they cause excessive voltages which burn out neighbors' appliances as they reverse the power companies line systems which assume a lower voltage at the end of the run.

If I put power into the grid I am going to blow up my neighbors toaster?

I doubt it, I dare say the power companies have adapted to rooftop solar alright.

You could use excess solar power during the day to run your hot water service—The Mechanic suggested that couple years ago.

The Greeny Munky from the GetUp! Propaganda Site's opinion is his alone. His post should be deleted just like he does on his GetUp! Propaganda Site.

As always he pushes the Greeny she'll be right view. Just like it is OK for windymills to kill hundreds of birds.

It is FACT that the high voltage from a house solar system does INCREASE the voltage on the mains above the normal value which shortens the life of neighboring appliances.

Rooftop solar panels overloading electricity grid
By ANNABEL HEPWORTH 11:00PM OCTOBER 12, 2011

Solar panel installer Chris Hart says the popularity of solar panels has led to increased loads on networks that cause problems if utilities don't adjust flows.

THE runaway take-up of rooftop solar panels is undermining the quality of electricity supplies, feeding so much power back into the network that it is stressing the system and causing voltage rises that could damage household devices such as computers and televisions.

Power distribution lines and home wiring were designed for electricity to flow from power stations to appliances, but households with solar panels do the reverse of this.

One of Australia's biggest electricity network providers, Ausgrid, yesterday warned that there was a "significant likelihood" that costs would have to rise because of the impact of the solar photovoltaic cells.

In a letter to the NSW pricing regulator, obtained by The Australian, Ausgrid warns that in areas with a high concentration of solar cells, voltage levels can rise and this can have "consequences for appliances and equipment in customers' homes". It can also cause solar systems to switch off.In Qld, some new applications for rooftop solar systems have been rejected and Energex now urges customers to check that a solar PV system can be installed without threatening the operation of the network.

In WA, Horizon Power has set limits on how much renewable energy can be installed in a system without affecting the power supply. Horizon is rejecting applications for new renewables installations in Exmouth and Carnarvon, and accepting them only from households, schools and not-for-profit organisations in Broome and Leonora.

Energex spokesman Mike Swanston said it was becoming difficult for electricity distribution authorities to set up the power system to ensure correct voltages when some houses in a street had solar and others did not.

"It is similar to the water network - the pipes get smaller and the pressure is designed to be lower as you get closer to the house," Mr Swanston said. "Start pumping water backwards into the smaller household pipes, and all sorts of strange things happen."


Energy Networks Association acting chief executive John Deveraux said the problem would only get worse as more rooftop solar panels were installed and the systems got bigger.

In southeast Qld alone, more than 22,300 rooftop solar systems were installed in the first 3 months of this financial year - more than the 19,000 installed in the 2009-10 financial year, according to Energex.

Federal Labor's target of producing 20 per cent of electricity from renewable sources such as solar power by 2020 has pushed up demand for the rooftop PV systems. So, too, have state-based schemes that pay generous feed-in tariffs to households for injecting power back into the grid.

Meanwhile, a flood of cheap solar panels being made in Asia and imported into Australia has offset moves by the government and some states to wind back their subsidies.

Power quality problems are worse in rural areas as the network is sometimes weaker and there is generally more space, meaning that bigger solar PV systems with capacities of 5 kilowatts or more are being installed, compared with the 1kW-3kW systems more common in urban areas.

Essential Energy, which operates powerlines in country NSW and parts of southern Qld, wants NSW to follow Qld's lead on introducing a cap on solar PV systems of 5kW to avoid power quality problems.

Endeavour Energy, which runs the network in Sydney's greater west, warns that some solar panel installers have not done voltage checks and other measurements to ensure the solar PV system operates adequately.

"The biggest problem we've got with the accelerated rollout is making sure every installation is fully compliant," Endeavour's general manager of network development, Ty Christopher, said.

Adelaide solar panel installer Chris Hart said the problems were worse in the summer months, when airconditioner use added to the stress on the system.

Mr Hart, who owns EcoSouth Solar Electricity, said areas with a lot of solar panels pushed the volts up to the maximum allowable level, triggering shutdowns in the individual systems and taking the load off the grid.

He said solar systems "drop out for a few minutes" when volts get too high, a phenomenon known as "tripping out".

"Then they try to come online again and it pushes the volts up again and it's very wearing," he said. "That's the problem with having too much solar in an area where the local authority hasn't got enough wires or copper in the street to hold the volts down."

Mr Hart said the size of conductors and cables in the streets would have to be upgraded "so it can handle lots of solar, versus times when there's lots of load and no solar".

"If you get a very, very hot night and there's obviously no solar, the mains voltage is going to drop a lot," he said. "If your wires aren't up to it, you've got a problem."

The network companies say measures such as retrofits and battery storage can stop the "tripping" but can be costly.

In WA, Horizon Power has set "hosting capacity limits" for renewable energy installations.

That is total crap. Solar PV accounts for a 3% increase in mains voltage which is well within spec. Stop spreading lies you lying little LNP turd. The people who design those PV inverters have to build them to spec so they know more about them than the LNP which couldn't even build a mouse trap.

There are over 2 million solar PV installs in Australia and I rarely hear complaints socko so put that in your pipe and smoke it. Those people are enjoying REAL significant discounts on their power bills rather than the hollow promises from the LNP which are still to materialize !!

Choice tips the bucket on the whole shady home solar panel affair.



Regulation plays catch-up with Australia's residential solar industry. A new report by CALC outlines numerous problems.
Andy Kollmorgen Last updated: 04 April 2019

...

Sorry state of solar

A report released today by the Consumer Action Law Centre's (CALC) erases any doubt that consumer protections have fallen behind Australia's chaotic residential solar industry.

Citing a number of case studies, the report paints a grim picture of the experience many consumers have had with the installation, performance and financing of solar panels.

The findings are well in line with recent CHOICE investigations, which have reported a doubling of complaints in 2018 and the widespread issue of pop-up solar installation businesses going bust and leaving customers stranded.

Too many families [are left] struggling with worthless and unaffordable solar power systems

"Unfortunately, consumer protection has not kept up with increased demand for solar energy, and this has left too many families struggling with worthless and unaffordable solar power systems," says CALC CEO Gerard Brody.

There are currently about 2 million household solar arrays installed in Australia.

In a recent CHOICE survey of more than 1000 solar owners, 30% reported they had a problem with the solar company.

Solar panel installation gone awry
CALC references a December 2018 report by the Auditor General's office which found that up to 25% of small generation unit installations inspected in recent years were rated 'unsafe' or 'sub–standard', a finding that's well in line with what CHOICE has been hearing from consumers.

In our earlier investigation into solar, one customer we profiled paid $29,000 for a 15kW system that never really worked.

It didn't help that the business she bought the system from, Elite Solar and Electrical Services, went into liquidation three months after she paid for it and before it had been hooked up to the grid.

She hired an electrician to finish the job, but the Australian Premium Solar (APS) monitoring system that was installed with the system still only works intermittently.

We have seen retailers either intentionally or inadvertently take advantage of the confusion

As the CALC report makes clear, it's not an uncommon experience.

The overriding issue is the diversity of stakeholders involved – solar retailer, solar installer, local electricity distributor, electricity retailer and a licensed electrical inspector – all of which need to work together to get the job done right but have no legal obligation to do so.

"We have seen retailers either intentionally or inadvertently take advantage of the confusion that this complex arrangement creates by denying responsibility and denying people's legal rights when solar systems are not performing as promised,' CALC writes.

Read our advice on how to pick a reputable solar retailer and installer.

Solar businesses gone bust
The CALC report points to an estimate by industry giant LG solar that 690 solar installation companies had a change in trading conditions, went into liquidation or stopped trading between 1 March 2011 and 31 January 2019, leaving 650,000 'solar orphans' in Australia – or installation owners who no longer have a business to contact if there's a problem.

When we spoke to LG general manager of solar and energy Markus Lambert in our earlier investigation he said the company adds 10 to 12 companies to the out-of-business list every four to six weeks.

Can the solar industry redeem itself? The way forward
CALC outlines a number of recommendations to improve consumer outcomes in the solar industry, including:

Solar retailers should be responsible for ensuring that solar panels are properly connected to the grid.
'Buy now, pay later' finance should fall under national consumer credit regulations.
Unsolicited solar sales should be banned.
Solar panel retailers should provide a 10-year warranty.
A solar default fund should be established to provide compensation for victims of shonky solar installers that have gone bust.

But the underlying issue is lack of government regulation.

"A key problem with self-regulation is that it is voluntary, so this should mean more solar retailers sign-up," Brody says. "But there are still problems not addressed by industry codes. There is still no simple way to resolve disputes with solar retailers, and we see too many examples of inappropriate or unsolicited sales supported by unaffordable finance."

give it up socko. Nobody reads your copy and paste crap.

I've monitored the line voltage in extreme heatwaves and it is not atypical for the line voltage to droop from 237 VAC down to as low as 217 VAC during the day with peak solar power feedins !! Also solar PV inverters are designed to cutout at a safe voltage for this very reason ! So much for solar PV over driving the grid Cheesy LOL
