Rooftop Solar Panels Are Almost All Facing The Wrong Direction

If you’re thinking that solar panels face south to capture the most sunlight and thus the most energy, then you’d be absolutely correct. Yet, solar experts are saying that rooftop panels should be installed facing west. This surprising turn can be explained by quirks in the US’ electrical grid.


This Cheap, New Solar Cell Doubles As A Battery

Solar power has an efficiency problem. When the electrons move from the solar panel to the battery that stores them, about 20 per cent of the energy is lost. But now, thanks to new type of solar cell, nearly 100 per cent of the energy is stored. That’s because the solar cell itself is the battery.


This Solar Sunflower Provides Electricity And Clean, Hot Water

This floral fabrication may look luxurious, but in fact it has a rather down-to-earth aim: to take renewable energy and warm water to remote, off-grid communities.


New Crystal Clear Solar Cells Could Power Your Smartphone One Day

The idea of a completely transparent solar panel has always been a bit of a dream. Such revolutionary technology would mean that we could turn windows into power generators and build phones with self-charging screens. Well, guess what? That dream is becoming a reality.


This LED Torch Is Powered By Spherical Solar Cells

Solar-powered torches consistently suffer from one glaring problem: They’re ugly as hell. But that’s nothing that a multidisciplinary creative collective from Japan can’t solve.


Simply Layering Solar Cells Could Make Them As Cheap As Natural Gas

It’s not uncommon to focus on excotic solutions to making solar power more efficient: new materials, complex tracking systems or unusual physical phenomena. But what about just stacking them on top of each other?


Spray-On Solar Cells Are Finally Viable Technology

The concept of spray-on solar panels has existed for some time, but it’s been hard to make them efficient. Now, a team of scientists from Sheffield University is using a new material to create a solar paint that could change that.


A New Adaptive Material Could Halve The Cost Of Solar Power

Solar power is one of the most reliable forms of renewable power — but it’s still expensive. Now, a team has developed a smart, adaptive material that could slash the its cost in half.


Australian Households With Solar Panels Might Pay Extra For Helping Generate Power

In Victoria, households that have installed solar panels on their roofs are facing an increase in the fixed rate they pay on every bill to connect to the state’s electricity grid. An extra 14 cents per day, or $51 per year, is being proposed to punish householders for helping to produce electricity.


Scientists Swapped A Toxic Chemical In Solar Cells For A Tofu Ingredient

Thin-film solar cells promise to bring flexible, low-profile solar power to all kinds of surfaces. Unfortunately, constructing thin-film panels requires cadmium chloride, a finicky, expensive and toxic material. Now, University of Liverpool scientists have figured out how to make solar cells using magnesium chloride, a compound so innocuous, it’s actually used in the production of tofu.
