Solar Tarp – foldable, portable solar power.

Posted on by — No Comments ↓

California based Lipomi Research Group are working on creating a solar tarp – which would have myriad uses for society. Let’s learn more about how these upgraded solar panels could help parts of the world where they don’t have access to regular electricity – and some of the technological challenges they’re facing trying to complete the project.

About the Solar Tarp technology

The Lipomi Research Group are focused on “identifying ways to create materials with both good semiconducting properties and the durability plastics are known for – whether flexible or not”.  They’ve been tinkering with perovskite solar cells, which are 1/1000 the thickness of a silicon layer in a solar panel. 

Darren Lipomi of the Lipomi Group, who is also a Professor of Nanoengineering at the University of California, said that their goal is to create flexible solar panels which are as efficient as conventional silicon but don’t have some of the drawbacks of it.

The goal is to develop flexible solar panels which are thin, lightweight, and bendable. Lipomi is calling their idea a ‘solar tarp’ – which refers to a solar panel which can be expanded to the ‘size of a room’, but balled up to the size of a grapefruit when not in use. The issues here are finding a molecular structure to make the solar panels stretchable and tough – this involves replacing the silicon semiconductors with materials such as perovskite. 

They’re also taking a look at polymer semiconductors / organic semiconductors (based on carbon, and used in place of perovskites or silicon in a solar cell). These aren’t as efficient, but are far more flexible and extremely durable.

According to The Conversation, the sunlight that hits the earth in a single hour contains more energy than the whole planet uses in an entire year – so there’s plenty more work to do on improving how we utilise the sun! We’ll keep an eye on the solar tarp project and let you know when it reaches the next stage.

Portable solar panels camping – fridges, reviews

Posted on by — No Comments ↓

Portable solar panels camping – if you’re thinking about a portable solar panel purchase for your campsite – to power laptops, charge phones, or even run a small fridge – you’re on the right article! Let’s take a look at the three main styles of portable solar panel and which you should choose.

Portable Solar Panels Camping

You have three main choices with regards to portable solar panels – and your choice depends on your unique circumstances.

Portable Folding Panels – the best option if you only camp a few times a year or you’re on a budget. These panels are quite heavy and inflexible, but they’re very simple to move to find a spot in the sun. Unless you’re a pro, we generally recommend starting here. 

Solar Blankets – the mid-range choice. More expensive than portable folding panels but worth the extra investment if you’re a frequent traveller – especially if you’re concerned about space and weight. It’s extremely simple to hang a solar blanket over the hood of your car, over your tent, on a nice sunny rock…

If you are going to have a look at the solar blanket option make sure you pay a little extra for a quality brand as these solar blankets aren’t the cheapest to begin with. If you’re going to invest in them it’s worth your while to get something that will last!

We can recommend the 112W SOLAR BLANKET AMORPHOUS CELLS from Redarc.

Fixed Panels – for the grey nomad or the frequent traveller, fixed panels have very low setup and are very easy to get working. You do need to park your trailer (or however/wherever you have fixed them) in the right spot to get as much sun as possible – which can be a little annoying. But in terms of performance vs. ease of use, these are the Cadillac of portable solar.

Alternatives for Portable Solar Panels

Although Portable folding panels, solar blankets and fixed panels comprise the bulk of what we’ll recommend for solar camping, there are a couple of caveats we should mention befor eyou go and buy anything.

If you’re not sure how much power you’ll require we can recommend the REDARC Solar calculator selection tool which is a fantastic tool for those planning a getaway!

If you want something simple just to charge a phone or a power bank we recommend giving Solar Paper by YOLK a look.

Any questions or feedback on any of these products? Do you have an issue with your solar powered camp? Please let us know in the comments and we’d be happy to help!

Solar Barbecue at Koroit Standoff Continues

Posted on by — No Comments ↓

The Moyne Shire and the Koroit Lions Club have continued discussions over who should fund and be responsible for maintenance over a proposed solar barbecue at the Koroit railway station. 

The $90,000 Solar Barbecue

The Koroit Lions Club had requested $20,000 from the council through community assistance funding towards the project, which, according to Standard.net.au, is estimated to cost close to $90,000, exclusive of ongoing maintenance. 

Cr Jill Parker proposed to give $20,000 to the club towards a ‘barbecue and shelter of any kind’ with the proviso that council are not responsible for ongoing maintenance. 

“I agree that the Lions Club have shown initiative in putting up a solar barbecue,” Cr Parker told a council meeting. 

“They have asked us for funding towards that and I would like to see that we make that available to them.

“The only provision I would add is that if it is a solar one, that (council) won’t be responsible for ongoing maintenance of a solar unit.”

Through a submission to the council, the club noted that it would be an environmentally friendly asset and some of the councillors, such as Cr Jim Doukas, agreed. Cr Doukas told the meeting that having “two bob each way” (i.e. offering the money but refusing to take responsibility for the project in an ongoing fashion) represented ineffective policy and will make the council look like “idiots”. Cr Doukas said the money should be given “in the interest of progress”, an idea which was shared by Cr Jordan Lockett who said it was not “just about a simple barbecue where old mate cooks his snags”, but an opportunity to be a “progressive shire and say we believe in solar energy”.

The $20,000 grant was eventually passed but, as discussed, the council won’t be responsible for any maintenance/repair. So we’ll see what happens after it’s built! 

Whichever way you cook it, $90,000 for a barbecue is certainly expensive. But when you put the investment into perspective, it’s great seeing the councils get involved in making facilities more environmentally friendly – such as the solar bins which have been rolled out to Cairns and in Noosa recently. Great progressive investment from the Moyne Shire!
