Microinverters Vs DC Optimisers – which is best? [infographic]

For those of you that want an easier way to understand the differences between microinverters (such as those manufactured by Enphase or APS) and DC optimisers (such as Solar Edge or Tigo), and don’t want to read this long post I published a couple of weeks ago then this 2 part infographic is for you!

The first part explains the difference between conventional, string inverter systems, DC optimised systems and microinverter systems (seasoned solar nerds may want to skip this and scroll straight down to part 2)

Part 2 goes into the pros and cons (and even picks a winner based on my humble opinion).

If you want to republish any of these infographics, no worries. All I ask is that you link back to this original post. I also have higher res versions which I can provide. Just ask!

* Note: the 2nd graphic has been updated to include 2 features of full Solar Edge systems (i.e. systems with Solar Edge optimisers coupled to Solar Edge Inverters) . Specifically Arc protection and individual fault bypass circuitry.

Solar Battery Storage Explained [Infographic]

I’ve written about hybrid solar and off grid solar systems before, but Tesla’s latest announcement about its new PowerWall battery is a real game changer for solar battery storage affordability – Morgan Stanley has a report that attests to this in greater detail. For those of you that don’t feel like slogging through an in-depth report, I’ve summarised the important distinctions between Hybrid and Off-Grid solar systems below. Enjoy!

The Huge Companies That Rely On Commerical Solar

Whilst commercial solar systems in Australia are steadily growing in number despite pushback from many electricity networks, the USA is forging ahead with enormous commercial systems.  America’s biggest companies, like Wal*mart, Costco and Macy’s are relying on solar power to reduce their bills. Here’s a great snapshot from the Sustainable Energy Industry Association which has some seriously impressive numbers on it.

When will Australia’s biggest companies (e.g. the miners) start installing more solar to power their operations?, Perhaps when the government stops subsidising their filthy diesel to the tune of about $8bn per year?

Anyway – all I can say is way to go USA! Here’s those amazing stats:

Fossil Fuel Subsidies are a Joke

I’m getting a lot of comments on Facebook at the moment along the lines of: “Solar needs to stand on its own two feet without subsidies of any kind”.

What these commenters (and our government) seem to miss is that fossil fuels in Australia – and around the world – are massively more subsidised than renewables.

This cartoon fresh from First Dog on the Moon, first posted on treealerts.org, sums up the situation nicely:

Solar Power For Your Home: The Absolute Basics

Back to absolute basics today on the SolarQuotes blog!

Here’s an infographic I got drawn up that explains the fundamental concepts you need to understand before buying solar for your home.

Yes, yes – I know for many of you dear readers this is completely obvious! But trust me, many folks out there starting on their solar journey do not realise that solar hot water panels don’t produce electricity.

Feel free to reproduce, republish and share to your heart’s content. The more knowledge out there the better for everybody!

Solar Power For Your Home: The Basics


New research shows most power bills are more than halved with solar.

Recent research by the Australian Solar Council shows that the average Aussie that has installed solar has seen an average 65% reduction in their power bills. And to pre-empt a gazillion comments – yes – this is achievable with a crappy Feed-In -Tariff too!  

They have produced a great infographic which sums up most of the benefits of solar that the anti solar brigade wish weren’t true. Here it is:

Micro Inverters vs. String Inverters [infographic]

I’ve had a lot of people ask me about the pros and cons of microinverters recently.  I have written a long and detailed description of microinverters, but for those who would rather learn about them without ploughing through 1000 words of my ramblings (and who can blame you!) I created this infographic about micro inverters vs string inverters. Hope you like it 🙂

Why the government’s direct action sideshow is a joke

“Direct Action” is nothing more than a sideshow. Do you agree?

Think solar is expensive? Be glad you’re not American!

Our American friends may get dirt cheap Nike runners, Levis jeans and iTunes downloads compared to us Aussies, but at least we can get some comfort from the fact that our solar systems are a helluva lot cheaper than theirs!

This infographic from those nice people at US site lineshapespace.com does a great job of spruiking the benefits of solar power, but also gives an insight into just how cheap Aussie solar is.

A big part of the price discrepancy is that the permit system for solar power is a bureaucratic nightmare in America. If you buy a 3kW solar system in the US you could pay $12,000 for it, of which $3,000 is permit paperwork! Compare that to about $5,000 in Australia of which about $0 is permit paperwork. In most states in Oz your installer simply fills in a 2 minute form online and gets ‘permission to connect’ within a day or so.

Here;’s the lovely infographic in all its glory – just be aware that the prices only apply to the US! [Read more…]

The Economics Of Solar Power in Australia [infographic]

I put this together to try and get across just how economically compelling solar power is if you look at the cost of electricity over 20 years instead of simply focussing on the up front cost.

If you can get good financing, solar power is an economic no-brainer for most households.
