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

August 14, 2015 2017-04-19T14:22:06 by 12 Comments

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)

Microinverters vs DC Optimisers. Part 1

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.

** This is only an opinion! If you vehemently disagree with my analysis, please leave a comment, or even write a well articulated blog post with your differing opinion, and I will happily publish it.

If you want a 5kW solar system in QLD – consider getting it before Sept 30 2015!

August 6, 2015 2017-04-19T14:23:38 by 22 Comments

Rules for installing solar in QLD change after 30 September

 

The Queensland electricity networks (hello Ergon and Energex!) are a fussy bunch. At the time of writing (August 2015) if you want to install a standard grid connect solar system bigger than 5kW, you need to jump through all sorts of technical hoops. And then the networks may also insist that you install a box of electronics that stops any of your excess energy being exported. That’s right you have to waste any excess clean energy instead of letting your neighbours use it! [Read more…]

Microinverters Vs. Dc Optimisers: Which option is best?

optimisers and microinverters

If you’ve decided on panel-level optimisation, which is the better choice, microinverters or optimisers?

Good grief this article is going to get me into trouble with some solar installers.  Why? Because by the end of it I will give my humble opinion on whether microinverters (e.g. Enphase) are better than DC optimisers (e.g. SolarEdge or Tigo). [Read more…]

Solar Systems in ACT to increase by $400 from 1 July 2015

June 19, 2015 2017-04-19T14:27:48 by 3 Comments
a meter and $400

$400 extra from July 1. Ouch.

ACTEW AGL have just announced that they are increasing the cost of installing a solar compatible, import export meter from July 1 2015.

Basically – if your application to connect is received after 30 June, instead of paying $66, you will be charged $500 for a new meter.

So if you live in ACT and have decided to go solar, it makes sense to sign up as soon as possible. You can get quick quotes from up to 3 ACT installers here.

ActewAGL General Manager Asset Management Stephen Devlin said:

“Charges for meter installation will be increasing. This change has occurred because of new National Electricity Rules that have been introduced that restructure the provision of metering in the industry.

 

As part of the Australian Energy Regulator’s final decision released on 30 April 2015, ActewAGL Distribution is required to move to full cost recovery for metering services from 1 July 2015.

 

Therefore, from 1 July 2015 ActewAGL customers will be required to pay the full up-front cost for new meters, including installation. Applications for any connection received before 30 June 2015 will be treated under the old pricing regime, where customers only pay for installation.

 

For solar customers, the cost of a new meter and installation would change from about $66 to $500.”

Solar meter charges will also be increasing by around $200 in NSW if you are on the Ausgrid network from July 1 thanks to the AER’s decision.

Tony Abbott vs. Elon Musk

June 16, 2015 2017-04-19T14:30:17 by 20 Comments

Who do you think has it right – Tony or Elon?

Posted by SolarQuotes on Thursday, June 11, 2015

 

 

Tony Abbott is convinced that solar and wind cannot power an industrial economy. Elon Musk believes it is very feasible to power the entire world with batteries and renewables.

Elon Musk Announces Powerwall Upgrade Before It Is Even Released

Elon Musk announces Powerwall V1.1

Earlier today, in the 2015 Tesla Motors shareholder meeting Elon Musk announced that the Powerwall will be upgraded from 2kW to 5kW steady power output (and up to 7kW peak) and keep the same price. He said that they were responding to criticism that the original 2kW was not enough to cope with the peak power demand of a typical home. [Read more…]

Solar Battery Storage Explained [Infographic]

June 9, 2015 2017-04-19T14:33:01 by 6 Comments

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!

Tesla Powerwall vs. AGL’s PowerLegato

May 23, 2015 2022-11-02T14:52:04 by 12 Comments

So AGL have thrown their hat into the solar battery storage ring with the AUO PowerLegato manufactured by Taiwanese Solar and Electronic conglomerate, AU Optronics.

So how do they compare on specs?

The cheap & cheerful way to add a Tesla Powerwall to your exisiting solar system?

May 21, 2015 2023-04-10T08:01:47 by 51 Comments

What might be the cheapest way to install a Tesla Powerwall + solar?

Note: The Tesla Powerwall 1 was released after this post and required a separate Battery Inverter and the existing solar inverter. The Powerwall 1 has since been superseded by the Powerwall 2, which has an integrated Battery Inverter – and AC couples to a solar inverter.

—–

[Note: This blog post is an educated guess on how the Tesla Powerwall might work based on stuff Elon Musk has publicly said and the press section of their website. So bear that in mind if making any decisions based on this post. Tesla have released sketchy and often contradictory technical details about the Powerwall, so it is impossible to be sure how the thing will work or integrate into an existing system. I’ve tried asking Tesla US and Tesla Australia for clarification, but with no luck.]

Since Tesla announced their low cost home battery, many solar installers have been looking for the cheapest way to integrate one into your home’s electrical system.

This has led to the emergence of a whole new category of residential solar system, that had never really been considered here in Australia before the Tesla announcement – the not-very-catchy “Hybrid Solar Without Backup” system.

This is a system which, to save thousands of dollars on the install, removes the ability for the batteries to power your home if the grid goes down. The batteries are only used to store solar energy. They cannot be used in an outage. [Read more…]

Will The Tesla PowerWall let you go off grid for $3500 ?

[Update: Since I wrote this post (on the day the Powerwall was announced) Tesla have added some technical details that open up the possibility of installing the Powerwall for a much lower price than this blog post estimates. But – and it’s a big but – the cheaper installation will not allow you to go off grid. More details on the alternative install option here]

 

So Tesla has just announced a 10kWh home battery pack that costs US$3,500 (AUD$4,500) . The Tesla PowerWall will mount unobtrusively on the wall of your home and store your solar energy, so you can use it at night or when the grid goes down.

Lots of twitterers are proclaiming that Renewable Energy utopia has arrived. You’d be forgiven from thinking that, thanks to Tesla founder Elon Musk, all we have to do to divorce the grid is shell out three and a half grand.

Look – I don’t want to piss on anyone’s parade. This announcement is massive in lots of ways which I’ll get to soon. But you won’t be able to go off grid for that kind of money (yet).

Here’s what Aussie homeowners should know about the Telsa Powerwall [Read more…]
