Solar Tarp – foldable, portable solar power.

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

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.

Container Roll Out Solar System – Portable Solar

ARENA (the Australian Renewable Energy Agency) have awarded a grant to ECLIPS Engineering to design, manufacture, and test its ‘diesel killer’ portable solar offering, the Container Roll Out Solar System (CROSS).

ECLIPS Engineering (formerly Sea Box International) are a Canberra based engineering firm hoping to do their part to help Australia do away with diesel generators in situations where a temporary power supply is required. They have created factory assembled 20 and 40 foot long solar panel arrays which fit in shipping containers and have minimal setup / teardown time. 

According to RenewEconomy, each 20ft unit has 2.1kW of power, and 7 of them can fit in a shipping container. The 40ft units has up to 4.3kW and can also fit seven to a container. 

ARENA have given CROSS $703,468 to to help the project, which has aims more lofty than just replacing diesel generators at work sites – the Container Roll Out Solar System could also help in defence situations, disaster recovery, for humanitarian needs, or for ‘temporary network augmentation’ (i.e. helping the grid if it’s malfunctioning or under severe stress).

ARENA CEO Ivor Frischknecht spoke about funding the project, and how they hope to see an eventual replacement of diesel generators in 99% of cases:

“CROSS units can be deployed in off-grid and fringe-of-grid areas, displace or offset diesel consumption and improve the security of existing networks,” he said.

“These renewable options can reduce some of the barriers to entry for potential renewable power users in remote locations, including short project durations and where power systems need to be periodically relocated,” Frischknecht said.

“Renewable energy can provide an emissions-free, silent energy system that could replace diesel generators in the long run.”

We’ve already reported on the Maverick by 5B, which is another prefab, low-cost ground mounted solar array – it’s great to see some more options available to try and minimise the amount of diesel generators used as a temporary power supply. 

We’ll keep you posted how the project goes and what the next steps are!

Solar Paper by YOLK – solar phone charger.

Solar company Yolk have released their ‘solar paper’ mobile phone charger. This lightweight, portable solar charger pairs with mobile phones, tablets, and powerbanks with high efficiency and a reasonable price. 

About Solar Paper

YOLK Solar Paper
YOLK Solar Paper (source: yolkstation.com)

The Solar Paper product was launched via a successful Kickstarter in 2015 where they raised over $1 million – it’s now been brought to market and you’re able to purchase one from the official YOLK website.

The Solar Paper comes in four models (all prices are in USD):

  • 5 Watts ($148)
  • 7.5 Watts ($198)
  • 10 Watts ($248)
  • 15 Watts ($348)

It’s able to output 5V, with 500mA regulated output per panel. The device is modular (extra panels can be connected via magnets) and additional 2.5 watt solar panels are $60 each. 

According to the official site, Solar Paper measures 9 x 19 x 1.1 cm when folded, and each panel weighs 65-75 grams (2.5 oz). Watt-for-watt, that makes it 70% smaller and lighter than competing products (no word on which products they’re speaking of, though). Solar Paper is 1.1 cm deep at its thickest point, making it suitable for a multitude of uses, like camping, hiking, or carrying around in backpacks/handbags. 

It has auto reset technology – so you don’t have to unplug and replug the cable every time you step into the shade (usually a drop in voltage would cause your device to ‘uncouple’ from the charger, requiring manual repairing).

The product is IP54 water resistant and includes an LCD meter to show how well the panels are working. One thing to note is that it doesn’t have any sort of storage included – so you could couple it with an inexpensive power bank such as one of the Xiaomi models so you can charge that if your phone is full. 

It won’t be able to charge something like a Macbook due to different voltages. You could, however, charge a power bank that’s suitable for Macbooks and then charge through that!

About YOLK

Korean based YOLK launched their first solar charger “Solarade” in 2014 via Kickstarter – it raised $72,000 and was moderately successful. Since then, they’ve been focusing on making solar power as portable and cheap as possible. The reviews on Amazon are good and the founding team (Sen Chang and Lim Sam) have since expanded rapidly. No word on their next product but hopefully it won’t be long!
