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.

Solar Camping Roundup – Products for Camping/Hiking

If you’re an avid camper or hiker, I’m sure you’ve already seen some of your fellow outdoor lovers using portable solar to charge their electronics while on the trail or at the campsite. Gone are the days when using a heavy (and expensive!) generator, wasting your car battery, or, even worse, using traditional non-rechargeable batteries were the only ways to charge electronics or run lights at the campsite. Solar camping is the way of the future! 

The rapid proliferation of advancements in solar panel technology has led to some exciting new ideas in the world of portable solar panels. So if you enjoy hiking, camping, (or you do and your family can’t live without their phones!) have a look at some of the options which are available to people who want to use recharge with renewable energy when they’re out in the wild. 

Buy Camping Solar Products in Australia

There a number of retailers in Australia offering a huge range of great products, from portable solar panels, foldable solar panels, solar torches, power banks to store the energy in, and much more. Quality can vary quite considerably so make sure you do your due diligence before purchasing anything too expensive. 

Kathmandu have a small range of products for campers and hiker such as the Goal Zero range of panels and some Kathmandu branded Power Banks and Hand Torches.
