SolarPVSunrise_310_233Company claims new solar module prototype sets new world record for module-level efficiency based on mass-production technology. New HIT N330 high-powered module set to debut in U.K.

Mere days after U.S. solar company SolarCity claimed to have produced the world’s most efficient rooftop PV module – achieving 22.04% module-level efficiency – Japan’s Panasonic has raised the bar even higher with today’s announcement that it has produced a 22.5% efficient solar module based on mass-production technology.

The electronics giant revealed that its latest commercial-sized prototype panel has been produced using solar cells based on mass-production techniques, utilizing a 72-cell, 270-watt prototype that incorporates Panasonic’s enhanced technology that can be immediately scaled into volume production.

The panel’s 22.5% conversion efficiency was verified by Japan’s National Institute of Advanced Industrial Science and Technology (AIST), and builds upon the 25.6% efficiency record the company set in 2014 at cell level.

“The new panel efficiency record demonstrates once again Panasonic’s proven leadership in photovoltaics and our ongoing commitment to move the needle in advanced solar technology,” said Panasonic Eco Solutions Europe senior business developer Daniel Roca.

Panasonic will also introduce its HIT N330 solar panels to the U.K. market next week. The high powered modules are mass produced with a conversion efficiency of 19.7% module-level efficiency, and a nominal power output of 330 watts, making them – Roca added – ideal for mature solar markets going big on self-consumption.

“For solar installers, the HIT N330 represents the ideal complement to their existing Panasonic solar portfolio, delivering the missing tool to achieve more power on any roof, and to maximize BOS savings and lower installation costs,” Roca said.

    If we can get to 25-30% at less than $0.75/W no later than 2020, it would be awesome for solar – and the death knell for a lot of old, dirty power plants.

      We are already at U$0.55/Watt with SolarCity. But their factory may not export to AUS.

        maybe they should revise their options

    It’s worth remembering that the sort of “efficiency” discussed here is only one of several measures. In many cases it’s not the most important.

    The “efficiency” discussed here is the proportion of energy in the sunlight striking a module which is converted to electricity. Higher efficiency is great.

    But most businesses and many residential solar customers have more roof space than they need to generate most or all of their own electricity. The efficiency such customers focus on is how much electricity they get PER DOLLAR. Let’s say they’re interested in the highest “financial efficiency.”

    We need to keep our minds open to the possibility that the greatest financial efficiency might be achieved by more & cheaper modules rather than the latest and most “efficient” modules.

    None of that is meant to diminish the importance of this sort of advance. It’s just a reminder that the path to the lowest price per watt might not take us via the most efficient individual modules.

      Possibly the notion of financial efficiency is important at this price point. However in future your roof will be covered with panels which will put solar efficiency back in the frame.

    As panel efficiency improves more people will be generation more power from suburban installs with battery storage being more effective sooner
