Anyone know of an American company building residential fencing using solar panels? Good idea or no? #solar
Rooftop #solar could supply two-thirds of global power, study finds https://www.pv-magazine-australia.com/2025/03/17/rooftop-solar-could-supply-two-thirds-of-global-power-study-finds/ #ClimateChange
@chris
Im at the point now when I see a big blank south facing roof I immediately think "why isnt it covered in PV panels?".
So much potential to tapped..

Verdammt, Waschmaschine und Geschirrspüler sind durch und der Tag hat noch ganz viel Sonne über. Tischlampe und Staubsauger sind auch schon geladen. #solar
Good news about our #pluginpv project in #Ukraine: “Yesterday we completed the installation of the panel: my husband fixed all the elements and ran the cables to the balcony.”
Our project partners from #EcoClubRivne are checking out how to install #solar on the #balcony. How to set ups such a system with a small battery, because there are lots of #blackouts in Ukraine, due to the destruction of the #powergrid by Russia.
Of course we also try to explore what landlords and gridoperators think and if they try to block small #pv.
"In yet another knee-jerk reaction to curb #RenewableEnergy growth through #solar net metering amid high grid electricity costs, [#Pakistan's] government on Thursday reduced the buyback rate by two-thirds to Rs10 per unit and scrapped net billing.
The decision [is] applicable to new net-metering consumers."

In a first for the US, wind and solar produced more electricity than coal last year, according to a new report from energy think tank Ember. Coal fell to a historic low, generating 15 percent of the country’s electricity compared to 17 percent from solar and wind combined.

What if we put solar panels on every roof in the world?
Scientists set out to explore the impact of covering every rooftop on Earth with solar panels.Their research found that swapping traditional energy sources for rooftop solar could actually cool the planet — lowering global temperatures by up to 0.13°C.

Aren't there extension cables for these solar panel connectors? I only find "MC4" cables, which seem to be only the connector on the receiving end but not the panell side. I need an extension for the panel side though. as 2 of the 4 panels are further away.
Do those extension cables even exist, or isn't this meant to be due to some frequency issues? Should I instead get another one of those cables with 4 connectors put them in a row if possible? (Seems to be possible?)

I have been warning both friends and family about this, and advising them to ditch mains grid ASAP & behold:

Net-billing axed, electricity purchases from solar prosumers capped at roughly a FIFTH of what they sold from the grid, full sales tax (GST) + surcharges irrespective of net consumption, no tax refunds
This is so stupid lol
#FunFactFriday: If every suitable roof in the world was covered in solar panels, it could provide 65% of global electricity, allowing for almost all fossil fuel-based generation to be replaced. Are you interested in getting rooftop solar? News Source: https://www.pv-magazine.com/2025/03/13/rooftop-pv-could-cover-almost-two-thirds-of-the-worlds-electricity-study-says/

'Scientists at NTU Singapore, have developed an innovative solar-powered method to transform sewage sludge - a by-product of wastewater treatment - into green hydrogen for clean energy and single-cell protein for animal feed.
Published in Nature Water, the sludge-to-food-and-fuel method tackles two pressing global challenges: managing waste and generating sustainable resources.'
Ooooh, man, did we have a stellar day for #solar energy production today! With electric heating, I usually don't get a day when I'm net positive until about a month from now. But after all was said and done, I'm up 12kWh despite it being between -5 and -9 Celcius for most of the day.
Positive externalities from #solar farms: number of birds on the mixed-habitat solar farms was typically twice that of the intensively managed sites, and three times higher than adjacent high-yielding cropland. .

Our PV+battery has been up about little over a week now. Today was hot and sunny; the first day of a 4-day heatwave and topped out at 31C while staying pretty humid.
We had AC on in a couple of rooms most of the day, using 26kWh of energy for all activity. The PV array produced nearly 44kWh of energy. We consumed 16kWh from the battery. At about 4:00pm, the battery was full.
Presently, the battery is discharging as we consume electricity from it, and it exports to the grid. Over the day, and across two price spikes we've exported 23kWh of energy. It's clearly not going to be any less in coming days.
On less sunny and hot days, it looks like we'll generate around 2x our consumption. On hot days like this, it will be even more (
Yes, it's going to take a handful of years to recover the outlay, but at this rate, we’ll both completely offset the cost of electricity supply to our house as well as earn enough FiT to offset a significant proportion of electricity supply for our guest cottages.
In NSW (and I believe other states), there are significant state government rebates on batteries alongside federal rebates on PVs. If you have the chance to invest in solar+battery, now is as good a time as any.
Interesting. Everyone has kind of assumed that putting big #solar arrays in a farmer’s field (so-called “agrivoltaics”) would probably further harm biodiversity. Someone finally tested that assumption and found out that the opposite is true: a well designed solar array allowed birds in much greater number and variety to live in the field compared to crops growing without the solar array.
