Some large PVs for rooftops were at a street market for €35 each. I’m not deeply knowledgable about them.. I just know that there are two varieties of solar panels and that the kind that are used from small appliances (e.g. calculators, speakers, lawn lights, etc) are junk. And that junk variety is sometimes used in large rooftop panels. What I was looking at resembled the kind I see on a bluetooth speaker with a slight blue tint so I was skeptical. The info on the backside of the panel indicated “1000 V”. The other thing is, all solar panels degrade over time and reach end of life after like 15 years (though this is improving). They may have been a good deal but I passed on them because I didn’t want to buy them on a blind risk.

How would I know how much life a used PV has left? Would a volt meter give that info, assuming it’s sunny when I encounter them again?

This article was almost surely placed because it came out that the tech firms were using accounting techniques to obscure their impact:

When the record was broken, solar was serving about 22% of load. A new record for solar energy generation in ERCOT was also set.

A solar well went into operation a few days ago in Dêrik in Northern and Eastern Syria. The well in the Şehid Xebat district is a central component of the district's water supply after the infrastructure in large parts of the region was destroyed by air strikes by the Turkish military. The project, funded by the Berlin State Office for Development Cooperation (LEZ), was implemented by the Berlin twin town partnership Friedrichshain-Kreuzberg – Dêrik together with the city administration in Dêrik and the "Make Rojava Green Again" initiative.

From January through July of this year, wind and solar in the U.S. generated more net electricity than power from coal, according to recent data from the U.S. Energy Information Administration (EIA).

According to the EIA’s Monthly Energy Review for July 2024, electricity net generation from renewable energy outpaced coal for the first seven months of the year so far, a first for the U.S.

Further, wind energy generation alone beat coal energy generation in two consecutive months: March and April. As CleanTechnica reported, wind energy installations produced 45.9 gigawatt-hours (GWh) in March and a record high 47.7 GWh in April, compared to the 38.4 GWh in March and 37.2 GWh in April generated by coal-fired power plants.
