Is Panasonic exiting the solar panel industry?

Reading Time: 3 minutes

In February 2021, Panasonic announced that during fiscal year 2022 (ending in March 2022), it will stop producing photovoltaic (PV) modules (aka solar panels). This announcement created some confusion about Panasonic’s future role in the solar industry, causing some to wonder if the company will stop selling solar panels altogether. However, according to Panasonic’s press release, this is not the case! The company stated that it will “continue to sell outsourced photovoltaic modules as it has been doing in North America.” So the question is: how does this shift in production impact the company and its customers?

How does solar panel degradation impact savings?

Reading Time: 8 minutes

The word “degradation” can be scary, but don’t let it frighten you too much: every product, from your cell phone to your shoes, degrades over time, and solar panels are no exception to this rule. Fortunately, solar panels degrade at a very slow rate relative to other technologies – in fact, even after 25 years, most solar panels will still generate at least 80 percent of their original solar power output!

Introducing Wallbox: the European-based smart EV charger company

Reading Time: 4 minutes

In 2019, the Solar Energy Industries Association declared the 2020s would be the ‘Solar+ Decade”. So far, their designation has come true, and then some: 2020 was the best year ever for energy storage deployment in the US, including at the residential level. But it’s not just energy storage that is being paired with solar; according to our recently released Installer Survey, in 2020, 1 in 12 solar installations also included an electric vehicle (EV) charger, while nearly as many people purchased an EV as purchased a solar panel system nationwide.

Solar-assisted heat pump

What are solar-assisted heat pumps, and how do you compare them?

Reading Time: 4 minutes

According to the U.S. Energy Information Administration, space heating and water heating can account for almost two thirds of energy use in U.S. homes—those bills definitely add-up! You can use many different types of energy efficient heating systems to offset these costs, including solar-assisted heat pumps (SAHPs), which some manufacturers claim can have payback periods as low as two to three years. These systems combine technology similar to solar hot water and air source heat pumps in order to heat water or small spaces in your home. SAHPs have existed since the 1970s, but have recently started gaining more attention due to their high efficiency.
