Emerging alternatives could be cheaper and greener. In Australia's Yarra Valley, new battery technology is helping power the country's residential buildings and commercial ventures – without using lithium. These batteries rely on sodium – an element found in table salt – and they could be another step in the quest for a truly sustainable battery.
Currently, lithium (Li) ion batteries are those typically used in EVs and the megabatteries used to store energy from renewables, and Li batteries are hard to recycle. One reason is that the most widely used methods of recycling more traditional batteries, like lead-acid batteries, don't work well with Li batteries.
While this may sound like the ideal path to sustainable power and road travel, there's one big problem. Currently, lithium (Li) ion batteries are those typically used in EVs and the megabatteries used to store energy from renewables, and Li batteries are hard to recycle.
However, batteries are both difficult to produce at the gigawatt-hour scale and sensitive to minor manufacturing variation. As a result, the battery industry has already experienced both highly-visible safety incidents and under-the-radar reliability issues—a trend that will only worsen if left unaddressed.

This metric quantifies how much a panel's power output changes for each degree Celsius change in temperature above or below 25°C. For example, a temperature coefficient of -0.
It's a range for the temperatures at which a panel can produce at its best. Here's an example. A 200-watt panel at 20 degrees Celsius (68 degrees Fahrenheit) might only produce 180 watts when the panel reaches 45 degrees C (113 degrees F). The ideal day for a solar panel is actually cold, sunny and windy.
As such, the manufacturer's performance ratings of solar panels are usually tested at 77°F (25°C) or what's called “standard test conditions.” To get a bit technical, solar panels are rated with specific high and low “temperature coefficients” that represent efficiency losses related to temperature changes above or below 77°F.
When discussing solar panel efficiency and temperature, one crucial term to understand is the “temperature coefficient.” This metric quantifies how much a panel's power output changes for each degree Celsius change in temperature above or below 25°C. The temperature coefficient is expressed as a percentage per degree Celsius.
The maximum temperature solar panels can reach depends on a combination of factors such as solar irradiance, outside air temperature, position of panels and the type of installation, so it is difficult to say the exact number.
When considering solar panels for hot climates, pay attention to the temperature coefficient. This tells you how much efficiency the panel loses for every degree above the standard test temperature of 25°C (77°F). Panels with a lower temperature coefficient, closer to zero, perform better in high temperatures.
Although extreme conditions will affect solar panel performance efficiency, solar panels are rated to operate in a very wide temperature range. Designed to reflect real-world conditions, most solar panels have an operating temperature range wide enough to cover every single day of your system's multi-decade lifetime.
Solar modules can shade crops where light intensity is in excess of crop requirements, reducing water evaporation; they can be mounted on agricultural buildings to power farm business energy needs; and they can export low-carbon electricity to meet wider demands for “green” power and the transition to a “net zero” global economy.
Finally, the solar farm has reduced maintenance costs because livestock can keep the grass short. All this is achieved while the solar panels provide locally generated, clean energy. However, if they're not set up properly, agrivoltaics may still cause problems.
Agrivoltaic farming could be a solution to not just one but both of these problems. It uses the shaded space underneath solar panels to grow crops. This increases land-use efficiency, as it lets solar farms and agriculture share ground, rather than making them compete against one another.
Finally, the solar farm has reduced maintenance costs because livestock can keep the grass short. All this is achieved while the solar panels provide locally-generated, clean energy. But if they're not set up properly, agrivoltaics may cause problems.
It is no surprise that some of the best locations on Earth for harnessing solar energy are often ideal places for agriculture and horticulture. However, intelligent design for multi-purpose land use can alleviate real or perceived conflicts between energy and food production.
Developers of solar farms are encouraged by the NFU to follow best practice guidelines for multi-purpose land use, combining energy production, continued agricultural management such as grazing, and creation of wildlife habitat.
Here's all you need to know about 'agrivoltaic farming' Agrivoltaic farming uses the shaded space underneath solar panels to grow crops. This article was updated on 28 October 2022.
