Genius Or Bonkers? US solar company glueing solar to roofs to reduce installation costs.

November 28, 2014 2024-07-03T11:45:32 by 14 Comments

Innovation in solar never ceases to amaze me. But I can’t decide if this particular innovation is genius or totally nuts.

US solar panel manufacturer Lumeta Solar have announced a new 175W solar panel design that is super thin, with no frame, a junction box on top instead of underneath, and get this: double sided sticky tape on the back.  The idea is that you simply peel the backing off the tape and stick the panel to the roof.

Coal vs Solar – Which is more space efficient?

November 19, 2014 2024-08-18T20:37:00 by 6 Comments

solar and a coal fired power station

This is a guest post by Greg Bell – which was conceived in the comments section of another post on this blog.

Take it away Greg:

——-

Some things we can say we know for sure about photovoltaics – the fuel is free, it’s quiet, and there are no moving parts. But other benefits are more controversial. Recently a claim was made to me that solar PV is actually more area efficient – that is, it generates more energy per hectare – than coal.

Specifically, the claim was

“The 1,600 megawatt brown coal Hazelwood Power Station and associated mine in Victoria covers 3,554 hectares. In a sunny location in Australia 20% efficient solar panels covering that area would produce more kilowatt-hours than Hazelwood’s average output.”

Let’s see if that’s true. [Read more…]

Are micro inverters & battery backup compatible?

November 5, 2014 2024-06-04T14:56:44 by 57 Comments
3 microinverters and 2 batteries

Can you combine micro inverters with batteries? Yes you can!

Can you use a micro inverter off grid? Or even for grid connect with batteries?

With the growth in the use of micro inverters, I’m starting to get more and more emails asking: can micro inverters be used in off grid (or hybrid) solar power systems? [Read more…]

Can LDK drag itself out of Bankruptcy?

Another large solar panel manufacturer appears to be in serious financial trouble. Bloomberg is reporting that LDK Solar, the world’s largest producer of wafers by capacity, has put it’s US operations into bankruptcy with over a billion dollars of debt. [Read more…]

The Huge Companies That Rely On Commerical Solar

October 17, 2014 2017-04-20T10:46:54 by 1 Comment

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:

The Solar Council Aren’t Lying. Your Government Is.

August 22, 2014 2019-04-15T14:38:41 by 9 Comments

The government has painted a big bullseye on solar power.

They’ve got it in their sights. They want the renewable energy target (RET) repealed and they’ll do just about anything to make that happen.

Well, anything but come right out and say, “We’re against renewable energy because because we want to protect the fat wallets of our buddies in Big Energy”.

No, they can’t bring themselves to be that honest.

Instead, they’ve engaged in an almost comical game. A game where they attempt to justify their solar enmity with numbers.

The problem, of course, is that numbers don’t lie. [Read more…]

Is Abbott about to axe the Solar Rebate (and push solar prices through the roof) ?

tony abbott and renewables

What does Abbott have in store for solar?

Well, I woke up this morning to a beautiful spring day. Only to see an inbox full of emails telling me that, according to the Australian Financial Review, Tony Abbott has already decided to scrap the Renewable Energy Target (RET) no matter what his review panel advises.

Bummer!

Let’s see what the rest of the papers have to say on the matter. Well, the most recent article I can find, published at 9am, is telling me that the government maintains it has absolutely no intention of scrapping the RET.

Hmmmmm. [Read more…]

Big Energy Has a Big Problem…But They Want YOU to Fix It

August 14, 2014 2023-06-22T14:23:03 by 4 Comments

Big energy has a big “problem”.  What’s the problem?

Competition. Competition from whom?  From Australian citizens like you who’ve told the big power companies, “We’ll  generate our own power, using solar technology. Thank you very much.  Shut the door on your way out.”

Why is this “big a problem”? Well, it’s simple economics that whenever a supplier generates way more “product” than the market demands, that product’s price drops through the floor.   And simple economics is biting Big Energy in the arse.

Like a pit bull terrier.

But it’s their fault.  They stuck their arse out to be bitten.  [Read more…]

How to find the most efficient solar water heater

August 13, 2014 2024-10-02T11:03:25 by 5 Comments
an evacuated tube solar hot water system

Is the evac tube system really more efficient than the flat plate system you have been quoted? Here’s how to find out…

When you are looking to buy a solar hot water system for for home, one of the most important things to check (apart from the price) is the efficiency of your Solar Hot Water System. The more efficient your system is, the better it will be at converting the sun’s heat to piping hot water, which means you will use your gas or electric boost less.

But with thousands of models of solar water heaters on the Aussie market, from flat plate or evacuated tube, to heat pumps it can be difficult to know how to find the most efficient solar water heater. Especially when each sales person says their technology / model is the most efficient! They can’t all be right…
