Twin creeks technologies are claiming a cost reduction breakthrough for solar PV

Last week’s column brought you the latest, world-record-breaking achievements of the University of NSW. This week, just to balance the books a little, we thought we’d bring you news of the latest incredible overseas advance in PV cells from overseas — just to prove that solar research is pushing back the boundaries the world over.

The name of the firm is Twin Creeks, which may or may not be a nod to the superb David Lynch-produced TV series of the early nineties (or am I showing my age here?), and the breakthrough is that photovoltaic cells are created using a hydrogen ion particle accelerator. [Read more…]

Samil Inverter Review: German magazine gives top marks

March 13, 2012 2017-05-02T10:48:08 by 20 Comments
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…]

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?

March 1, 2012 2017-05-02T10:55:07 by 26 Comments
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

February 21, 2012 2017-10-20T13:10:56 by 7 Comments

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?

February 17, 2012 2018-05-09T11:20:28 by 55 Comments

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

February 3, 2012 2023-09-13T13:44:30 by 22 Comments
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?

January 10, 2012 2016-05-30T14:06:40 by 15 Comments

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…]
