How does the LG Resu compare to the Tesla Powerwall?
If you are looking at a 6.4kWh Lithium-Ion battery for use with your solar power system in Australia right now, you are probably tossing up between a LG Chem Resu 6.4Ex and the Tesla Powerwall.
To help you decide which one is for you – here is a side by side comparison, and some commentary on their warranties below. [Read more…]
Duracell has just announced its first product in the home battery storage market – competing directly with Tesla.
Well, it finally happened. After sitting on the sidelines as the solar battery storage boom unfolded around it, the world’s biggest name in batteries has finally joined the party.
Today, April 1, at a glittering press event in Bethel, Connecticut, Duracell’s VP of Solar Storage, George Leclanche, unveiled the Duracell Ultra Lithium Home Battery – which will be available in priority markets including Australia by the end of the year. [Read more…]
The cost of a storing each kWh in a Tesla Powerwall is much more than you might think.
[Update: on Aug 16 2024 Tesla announced the Powerwall 3Â ]
[Update: on Oct 28 2016 Tesla announced the Powerwall 2Â ]
[Update: In June 2016 Tesla updated the Powerwall warranty – details here]
11 months ago Elon Musk jumped on stage and announced the Powerwall.  The Tesla data sheets released after Musk’s presentation proclaimed we would soon be able to buy a 7kWh daily cycling Powerwall for US$3,000. It would be guaranteed for 10 years with an optional 10 year warranty extension available. Treehouse, one of the companies who Tesla announced would be first to sell it in the US declared that $3,000 was the retail price – not the wholesale price and we all went “Wow! Cheap batteries have finally arrived.”. [Read more…]
Here are your options and gotchas when adding solar panels to an existing system.
Please note: this post was written in 2016
***Please read this 2022 post for the latest information on upgrading your solar panel array.***
So you’ve got solar panels on your roof and you want more so you can get your bills even lower?
Do you want your new solar system to be ‘battery ready’? First you have to know what that actually means…
Most homeowners I speak to are really keen to get batteries.
Just not right now.
They want to wait a few years until the price has come down substantially. And who can blame them when a typical battery system in 2016 has a payback of 20 years but only carries a 10 year warranty.
So clued up homeowners looking to buy solar are really keen to get a system that they can easily add batteries to in the future.
Solar companies have caught on to this and we are starting to see solar systems sold without batteries but advertised as ‘battery ready’.
Here at SolarQuotes we are getting more and more questions about what ‘battery ready’ actually means in these adverts, and the best way to buy a solar system that really is battery ready.
The truth is that ‘battery ready’ can mean lots of things. Many of the ads I have seen are technically correct – in that you can add batteries in the future – but probably not as easily, or with the functionality that many people will be expecting.
In my opinion if you are going to claim a specific solar system as battery ready then you must be more specific and explain the basis on which you are making the claim.
In this post I’ll go through 3 different interpretations of ‘battery ready’  – make sure you understand which one you are being offered. [Read more…]
Just 3 of the Powerwall alternatives now available in Australia.
Manufacturers of Powerwall alternatives struggled to be heard last week as the mainstream media went crazy over the beautifully stage managed, first residential Powerwall battery storage installation in Australia.Â
The mood was one of expectation and excitement — mixed with a tinge of dread in fossil fuel circles – as it heralded the advent of affordable home batteries from Tesla and its many competitors in the home battery market. [Read more…]
How the Tesla Powerwall and Enphase AC battery specs compare.
In terms of good marketing in Australia, two batteries stand head and shoulders above the rest in Australia right now: the Tesla Powerwall and Enphase AC battery. Both of which are due for mainstream release in 2016.
(There are lots of alternative batteries around – many of which are worth considering – but this article is about Tesla vs Enphase due to the volume of enquiries we get about them.) [Read more…]
Part 1 of an interview with Enphase VP of Quality & Reliability: Ciaran Fox
In my experience solar installers either really love microinverters, or are incredibly wary of them. There seems to be very little middle ground.
Those who love them talk about their ease of installation, increased power output, flexibility of panel layout, panel level monitoring and shade performance.
Those who are wary of them generally worry about their reliability.
A microinverter is a box of sophisticated electronics that sits on your roof (under each solar panel). In Australia your roof gets hot! And if a microinverter fails, replacing it means climbing on the roof and removing the panel. So installers’ concerns are understandable.
A microinverter. You generally use one per solar panel instead of a single large central inverter. They are about as big as an iPad mini
To get some authoritative answers, I asked installers that I know to send me their toughest questions about microinverter reliability.
I then put those questions to Ciaran Fox who is the Vice President of Quality & Reliability at the world’s biggest microinverter manufacturer, Enphase. [Read more…]
Caution – extremely cheap solar has a high cost
The best deal is very rarely the cheapest deal. This is something we all understand intuitively.
So why do we get so easily get seduced by unbelievably cheap solar deals that appear so totally believable?
Let me be totally up front with you. I did not set up SolarQuotes as a tool for people to find the absolute cheapest solar systems on the market. [Read more…]
Learn how to hack the government’s electricity bill data for fun and profit…
If you own a solar system but haven’t shopped around the electricity retailers in a while, your bills are probably higher than they need to be.
The big gentailers, Origin, AGL and Energy Australia have made their disdain for solar very clear. They all lobbied to scrap government support for small scale solar during Tony Abbott’s RET review in 2014. And unsurprisingly their electricity tariff offers for solar owners are pretty ordinary.
Luckily there are lots of smaller retailers around these days that often beat the big names. And a handful of those offer solar Feed In Rates that are higher than the rates mandated by your state government. [Read more…]
