Solar Inverter Efficiency: What you need to know before buying.

January 28, 2012 2025-07-29T09:39:58 by 1 Comment

Everything goes through the inverter so its efficiency is critical.Solar inverter efficiency is a critical specification that directly affects the efficiency of your entire solar system. It is almost always a much more important consideration than solar panel efficiency.

All the power generated by your solar panels has to go through your inverter before you can either use the power in your home or export it to the grid (and get paid) so every percent of extra efficiency that you can squeeze out of your inverter will directly improve the performance and payback of your solar system.

So do you just need to pick the inverter with the highest “efficiency” number on the specification sheet? Well I’m afraid it isn’t quite that simple. (You guessed I was gonna say that didn’t you?!) [Read more…]

The announcement last month from R&D company Silex Systems that construction on Australia’s largest solar power station at Mildura, VIC, has begun gladdens the heart. And the hip pocket nerve. After all Victorian and federal taxpayers are helping to fund this venture to the tune of around $120 million.

Australian Researchers Break World Record for Solar Panel Efficiency

July 9, 2011 2025-07-29T10:05:24 by 1 Comment

By Rich Bowden

Now this is the sort of news your SolarQuotes.com.au correspondent likes to deliver. After weeks of wading through government reversals on solar feed-in tariffs, reporting on the various sniping at the edges of the solar industry and talking about savage cuts from state and federal governments affecting the Australian renewables sector, here comes a really positive development.

4 Ways to Know You’re Talking to a Solar Moron

March 14, 2011 2025-07-29T09:42:08 by 3 Comments

The title of this blog post is not exactly accurate. “Moron” implies that they don’t know any better. In actuality, most of the people who throw these lines DO know better.

Much better. But they still use these lines because they help them to sell more product. Which makes them much worse than morons. [Read more…]

How Important Is Efficiency When Choosing A Solar Panel?

November 15, 2010 2025-07-29T10:06:54 by 21 Comments

I get a lot of emails from people asking “Which is the most efficient solar panel on the market?”.

Last time I checked, the awesomely awesome Sanyo HIT 195DA3 (note: now manufactured under the Panasonic brand) laid claim to the most efficient panels in production at a whopping 20.5% panel efficiency!

(And before you SunPower fans swamp me with emails – yes, I understand that this is including light coming into the back side of the panel, which is would require special mounting – see the pic below. On a typical roof, the Sunpower E20 327W will be the most efficient at 20.4% panel efficiency)

Mounting a solar panel to allow "backside irradiance"

An example of Sanyo HIT solar panel mounting to maximise efficiency.

But whilst solar panel manufacturers like SunPower and Sanyo battle it out for the “most efficient panel” gong, the question we really need to ask is: “Is the most efficient panel the best option for your roof?”.

Chinese Solar Company Says Improved Solar Efficiency On The Way (based on Aussie Technology!)

April 7, 2009 2017-05-03T14:37:44 by 2 Comments

The largest producer of solar panels in the world, Suntech Power Holdings, has recently reported more information regarding its latest Pluto technology. This new technology has made substantial progress in improving the conversion efficiencies of solar cell technology

Although there have been a number of improvements in technology in the industry overall, none of the others are yet ready for commercial distribution. Although the Fraunhofer Institute achieved a solar cell efficiency of over forty percent, it, also, is far from ready for mass production.

Already in the process of mass production, Suntech’s Pluto technology has employed solar panels with efficiencies of 19% in monocrystalline technology and 17% in polycrystalline panels. Other current technology currently has efficiencies of 18% and 14% respectively.
