Samil Inverter Review: German magazine gives top marks

Samil Power Solar River Inverter

The Samil Inverter got a great review in the German Photon Magazine in August 2011

Samil Inverters are very popular in Australia. They are great value, and have great specifications on paper. However I get a lot of emails asking me if this Chinese made solar inverter is any good.

It is a fair question. The inverters are a lot cheaper than their German made competition (like SMA), and are a relatively new player in the market. Plus there are a lot of solar salespeople out there that are peddling the (somewhat xenophobic) line that all Chinese made solar components are crap.

So what’s the truth? Are Samil Inverters any good? [Read more…]

Interview with Paul O’Reilly of the Rainbow Power Company

Rainbow Power Company Logo

Rainbow Power Company – one of Australia’s oldest solar companies

In this, the first in what we hope will be a number of interviews with solar opinion leaders, business people and experts in the solar industry we chat with Paul O’Reilly, director of the Nimbin-based Rainbow Power Company. Sit back and enjoy as Paul talks feed-in tariffs, the almost constant boom and bust cycles in the Australian solar industry and his optimism for the future.

The solar industry must have changed a lot since Rainbow Power Company first set up? Do you think this has been for better or worse?

How Does Temperature Affect Your Solar Inverter Power?

Inverter positioned badly

Don’t mount your inverter where the sun can cook it!

If you’ve been reading this blog for any length of time you are probably already aware of how high ambient temperatures negatively affect solar panel performance.

But did you know that when it gets hot outside, those scorching Aussie temperatures can also cause the efficiency of your solar inverter to drop? [Read more…]

8 Reasons To Get A Site Inspection Before Buying Solar Power

a solar inspection

If you are considering putting some solar panels on your roof, then I strongly recommend that you have a physical site inspection before getting firm quotes.

Since I started SolarQuotes many years ago, we’ve handled hundreds of thousands of quote requests and over those years the most frequent complaint I’ve had from people looking for quotes is:

“This solar installer won’t even give me a ballpark price for a solar system! He’s insisting on coming round to my house first!”

Rubbishing the idea that solar power is not commercially viable

Bin with solar panels

Australian waste management group Veolia Environment Services are very proud of themselves this week as they prepare to celebrate the installing of their brand-new, state-of-the-art solar powered energy source at its Arndell Park facility in NSW.

On Feb.23, the company will be hosting a knees-up to mark the recent installation of the 50 kW solar panel system, which has been added as part of the company’s drive towards boosting its renewable energy source. The project — in collaboration with BP Solar and installed by Solar Technology — is a key part of the Blacktown Solar City project, described, a little breathlessly in a company press release of Feb. 14, as being derived from “…a $94 million Australian Government initiative to help lay the foundations of a sustainable energy future.”

The STC Price: Is Your Solar Installer Ripping You Off?

A solar crook

Short Answer: Probably Not.

Longer Answer:

Ah, the joys of STC prices! Every so often I get an email from someone who is desperately worried that their solar installer is using the STC price to rip them off.

The suspicion is usually kicked off by one of two things: [Read more…]

How To Read A Solar Panel Specification: Part #1 Power & Temperature Specs

Magnifying the NOCT on a solar panel specification

Discover how to read a solar panel specification

Does a solar panel specification with “Max Power” rated at, say 190W, really produce a maximum power of 190W when it is on your roof in the blazing sun?

Short Answer: Not on your nellie!

The max power rating (in Watts) that your solar panels are rated at is the figure that everyone quotes when talking about “panel size”. If the installer or salesperson talks aout a “190W or 250W panel” they are talking about the “max power” rating of the panels. This rating is based on the power output measured from that panel under “Standard Test Conditions” (STC) that, unfortunately, are a long way from “Real World Operating Conditions”.

AC Solar Panels (microinverters) : The #1 Solar Trend to watch for in 2012?

Will 2012 be the year of the AC Solar Panel?

Before answering that question I should probably explain exactly what an AC Solar Panel is…

An AC Solar Panel converts sunlight to AC electricity at the solar panel.

 

What is an AC Solar Panel?

The short answer is: An AC Solar Panel is a solar panel that takes sunlight in and spits AC (Alternating Current) electricity out. This compares to a “conventional” DC Solar Panel which takes sunlight in and spits DC (Direct Current) electricity out.

AC Electricity is the type of electricity you need to power the appliances in your home. DC panels need a Solar Inverter to convert the DC electricity to AC. The big advantage of AC panels is that there is no need for an inverter to do that conversion, so you have a really simple design, a simpler installation, and adding extra panels becomes almost plug and play.

Will your solar power system protect you from power cuts?

I get asked this question a lot.

Unfortunately the short answer is: No – A standard grid connect solar system will not protect you from blackouts.

Kind of counter intuitive isn’t it? You go to the trouble and expense of your own little solar power station, and then you have no power if the electricity grid goes down. [Read more…]

Solar Power Forecast for 2012: More stability, better forecasts, fewer conspiracies?

solar to grow in 2012?

This year should be the year that renewables start to take off in Australia:

  • We will have a carbon tax in place that will support renewable energy and overseas money is starting to flow in.
  • Large scale solar is finding funding, following the trend from overseas.
  • Chinese production of solar panels is bringing the cost of solar energy rapidly down towards that of fossil fuels.

But there is one factor that governments, both federal and state, need to provide: stability.

The solar industry needs to sense that financial support given in one year won’t be withdrawn the next when the going gets tough or when a newly-elected government reverses the previous government’s solar policy just because they can.

Certainly in the case of solar energy the governments’ efforts to forecast costs got an “F” grade this year. In a New Year’s resolution that we think makes complete sense, the Australian Solar Energy Society (AuSES) has promised to carefully watch over the government’s solar forecasting in 2012 on behalf of the nation’s solar industry. Reading between the lines it seems AuSES is none too pleased with the end-of-year report card for government forecasting agencies.

“As a national voice for Australia’s solar industry, the Australian Solar Energy Society has made a New Year’s resolution: to work more closely with Government agencies to ensure there’s no repeat of the 2011 solar forecast mistakes,” the society said in a recent release.

This brings an image of government forecasters sitting in class rooms watched over by AuSES teachers. The solar forecasters, gazing out into the playground where their fellow  number crunchers are all playing, before looking down and writing: “I must not bugger up the solar forecasts again” 100 times.

Am I being too harsh here? After all a forecast is just as it states: a forecast. But surely it should have some relation to the outcomes?

The AuSES release points to four key areas where forecasts had to be speedily revised to bring them to within a bull’s roar of real outcomes.

1. The Productivity Commission’s overstating of the cost of solar subsidies per tonne of CO2, forcing it to revise down the cost of solar subsidies from $431-$1041 to $177-$497.

2. The Energy White Paper, released by the federal government, which overstated solar’s cost by a factor of three.

3. The Treasury Department’s estimate that the country would have around 9 gigawatts of solar by 2050. However 1.2 gigawatts has already been installed, with yearly installations increasing ten fold since 2009.

4. The NSW Government, led by Barry “The Terminator” O’Farrell, forced to revise the cost of the state’s solar bonus scheme down by nearly a quarter.

Hardly inspiring is it? No wonder AuSES chief executive John Grimes described 2011 as “a horrible year for government solar forecasting”. And why are the forecasts always so against the interests of the solar industry? Is the reason for the solar forecasting simply the innocent result of a culture of excessive drinking and partying in our state and federal capitals? Or are there other motives at work?

There you go folks, a nice little conspiracy theory to kick off the year. Wishing you all a safe, happy and productive New Year.
