In a bid to offer sustainability and charging power, Japan’s new solar film is set to be a great alternative for houses that can’t handle the weight of solar panels, and it could be the future for Nissan cars, too.
While many firms have been trying to power new cars with solar panels, it’s been almost impossible to generate more energy than is lost through the added towing weight.
But what happens if you can take away the weight and have a solar film wrap?
Well, we could be about to find out, as a company in Japan is creating just that.

Solar film could replace panels and be a winning recipe for houses and cars
Solar energy is a major player when it comes to electric cars, with the technology harnessing the sun’s power and converting it into battery life.
Soon, solar panels are set to be in mass supply to buildings like parking lots, in a bid to provide free charging.
But a firm in Japan is taking things a step further and has created a new solar film that could replace the heavy solar panels.
New startup PXP Inc. and Tokyo Gas Co. have partnered to create a solar film using chalcopyrite solar cells, which weigh significantly less than a usual panel and don’t need the heavy metal frames to be attached to buildings.
Instead, it can be installed on slate, tin, and even glass.

But others are thinking that you could even add the solar film to cars.
One man has used a similar tech on a DIY Tesla, and he found resounding success.
Now, Nissan appears to be stepping up to the plate as the first manufacturer to give it a go
Nissan leads the charge with new solar film tech
In a blog post on the Japanese Nissan Newsroom, it was announced that the popular car manufacturer has also joined in a partnership with the new solar film firm.
Currently, the tech is being applied to Nissan buildings, but it might not be too long before we see the adventurous team make car roofs with this wrap.

Solar energy has already been proven to bring down charging costs for EVs significantly, which is a win-win for the renewable planet-saving consumers.
