Self-storage rooftops will become a nationwide 100MW+ solar farm

Posted on by

Electrek reports that a solar energy company is renting 8.5 million square feet of roof space from the National Storage Affiliates Trust’s (NSA) buildings for its newest solar panel project.

The commercial and community solar developer Solar Landscape’s new rooftop solar panel grid on the NSA’s 1,052 self-storage facilities and properties across 42 states and Puerto Rico are expected to produce at least 100 megawatts of solar capacity. The NSA, headquartered in Greenwood Village, Colorado, is one of the nation’s largest self-storage operators with brands like iStorage, Move It, Northwest and SecurCare.

These solar energy panels won’t just generate power for the NSA’s facilities. The panels will also provide clean power to nearby businesses and homes for a discounted price.

One of the challenges of implementing solar energy is finding enough space for the solar panels. These panels can take up a lot of space, like the Noor Abu Dhabi solar plant that set a world record in 2019 with 3.2 million solar panels taking up over 3 square miles of space.

Solar Landscape and the NSA may have found an interesting solution to solar panel projects’ space problem. If this partnership is successful, it could inspire similar deals for other communities looking to benefit from solar power technology.

Oxford scientists’ new light-absorbing material can turn everyday objects into solar panels

Posted on by

Oxford University scientists may have solved one of the greatest hindrances of expanding access to solar energy. Scientists from the university’s physics department have created an ultra-thin layer of material that can be applied to the exterior of objects with sunlight access in place of bulky silicon-based solar panels.

The ultra-thin and flexible film is made by stacking layers of light-absorbing layers of perovskite that are just over one micron thick. The new materials are also 150 times thinner than a traditional silicon wafer and can produce 5 percent more energy efficiency than traditional, single-layer silicon photovoltaics, according to a statement released by Oxford University.

Dr. Shauifeng Hu, a postdoctoral fellow at Oxford’s physics department, says he believes “this approach could enable the photovoltaic devices to achieve far greater efficiencies, exceeding 45 percent.”

This new approach to solar energy technology could also reduce the cost of solar energy. Due to their thinness and flexibility, they can be applied to almost any surface. This reduces the cost of construction and installation and could increase the number of solar energy farms producing more sustainable energy.

This technology, however, is still in the research stage and the university doesn’t mention the long-term stability of the newly designed perovskite panels. Going from 6 to 27 percent solar energy efficiency in five years is an impressive feat but stability has always been limited compared to photovoltaic technology, according to the US Department of Energy. A 2016 study in the science journal Solar Energy Materials and Solar Cells also noted that perovskite can provide “efficient, low-cost energy generation” but it also has “poor stability” due its sensitivity to moisture.

Solar energy has also become a cheaper power option just over the last decade. The cost of solar photovoltaic technology has dropped by 90 percent in the last 10 years, according to the Global Change Data Lab.

New solar energy farms are popping up all over the world. The US Department of Energy announced earlier this month its turning an 8,000-acre piece of land that once housed parts of the nuclear weapons program known as the Manhattan Project into a solar farm. Last month, Google invested in a Taiwanese solar company to build a 1 gigawatt pipeline in the region.

Solar bot is a smart device concept that makes solar power more accessible

Posted on by

Solar power is something that is pretty important if we need to reduce our carbon footprint and our electricity consumption. But it’s still not something that’s easily accessible for everyone or something that’s portable and easy to use or access. A recent invention from Jackery, a portable power and green outdoor energy company, might be the thing we need to revolutionize how the ordinary consumer can access and use solar energy.

Designer: Jackery

The Solar Mars Bot was named one of the Best Inventions of 2023 by Time Magazine, specifically in the Green Energy category. It is a robot type machine that is a photovoltaic energy storage device equipped with various sensors to enable it to gather as much solar power as it can store. It has laser radar and camera modules to help it get around. It’s smart enough to roll around and find spots where it can align its panels with sunlight and even avoid obstacles.

The energy that it is able to gather is stored in a lithium iron phosphate battery and then you will be able to power your devices through any of its connectors including ordinary earthed sockets, USB-C and USB-A ports. You can take this solar robot with you when camping or on any outdoor activity or when you’re just lounging in your backyard or swimming pool and you need to charge your devices.

For now it seems to still be in the conceptual stage and Jackery may be creating a prototype for testing. But if ever it reaches the consumer market it will make solar energy common for those who are conscious about their electricity consumption. Hopefully we see some progress with this “best invention” soon as we all want to be able to regulate our carbon consumption over the next few years.
