OVERALL VIEW OF SMUD'S ONE-MEGAWATT PHOTOVOLTAIC FACILITY (FOREGROUND) AND THE 913-MW RANCH OSECO NUCLEAR POWER PLANT.
SACRAMENTO MUNICIPAL UTILITY DISTRICT'S ONE-MEGAWATT PHOTOVOLTAIC FACILITY (SMUDPV1) IS THE INITIAL STEP IN A PLANNED FIVE-PHASE, 12-YEAR VENTURE TO CONSTRUCT A 100-MW PHOTOVOLTAIC POWER PLANT NEAR THE RANCHO SECO GENERATING STATION. THE FACILITY IS COMPRISED OF 896 PHOTOVOLTAIC PANELS--MORE THAN ONE MILLION SOLAR CELLS--MOUNTED IN SINGLE-AXIS TRACK- ING ARRAYS. THE PHOTOVOLTAIC DEVICES, MANUFACTURED BY ARCO SOLAR, ARE MADE FROM SINGLE CRYSTALLINE SILICON AND CONVERT SUNLIGHT INTO DC ELECTRICITY WITH 11-PERCENT EFFICIENCY. EACH MEGAWATT OF THE PLANNED POWER PLANT REQUIRES ABOUT NINE ACRES OF LAND AND WILL PRODUCE ENOUGH ELECTRICITY TO POWER 300 HOMES. SMUD USED ITS OWN FUNDS, AS WELL AS THOSE BORROWED FROM DOE AND CALIFORNIA'S ENERGY COMMISSION, TO FINANCE THE INITIAL, $12 MILLION MEGAWATT. COMPLETION OF THE ENTIRE 100-MW PLANT IS EXPECTED IN 1993.

A recent solar panel installation just down the road from my house. I wonder which cowboy firm did it. I reckon most of the panels are too shaded to be worth having.

I have photographed many ISS solar transits but today got my first solar transit of Tiangong, the Chinese Space Station. Tiangong is currently about 16.4 meters in length by about 4.2 meters in diameter, much smaller than the ISS which clocks in at about 108m long by 73m wide).
The best time to photograph a transit is when the Sun is highest in the sky so the station is closest to you it can be. That means you want to photograph close to the summer solstice (which was a few weeks ago so check) and close to local noon (the transit was at 12:07pm so check) resulting in a range of 389km. Tiangong appears to move really fast across the Sun at that low obrit!
Here is a video of the transit and two composite photos (the second photo is a cropped version of the first).
Trying out a solar filter on a Novoflex 400mm m42 mount lens. Can just make out a small sunspot. The April 8, 2024 eclipse is coming...

Solar panels at Tivoli Gardens in Copenhagen. Output on this partly
cloudy day was 360W when I walked by.
Trying out a 150Wp #solar panel at my apartment. Max today was 100W. Have to figure out a way to mount it as a window. #solarenergy #solarpanel #green #electricity #sustainable #apartment #12V #battery #offgrid

Yesterday had some good clouds that dissipated near 3PM so I decided not to go out and hunt for sunset pictures. That was a mistake because some more clouds moved in and made fantastic sunset.
The solar panels catch the final light of the day.
Cheers.
This is a slide of the total solar eclipse that occurred on February 26, 1979.
My father-in-law found some old slides at the local dump. I've been slowly transferring them to digital pictures and have found some very interesting pictures. This is my Vivian Maier project (without the financial gain).

San Antonio, Texas: This a small part of a 445 acre solar (PV) farm. It is the first of 7 know as the Alamo Solar Project. It contains 167,680 panels rated at 295 watts each and the total output is 41MW.
Solar sailers are the newest toys of the Algorian elite... The model shown here is the "Guilty Pleasure" of the infamous guerilla banker Gilga Meshaneed.

The solar panels that artist Robin Salant is using to power her light installation in the Sears Crosstown building.
Nine of the twelve solar panels. This is a 1.6 kilowatt system. After the rebates and tax credits it will cost us $7,500 or so. But then we can start selling back power and watching the meter run backwards.

The Solar Decathlon 2022 Competition Event took place at the National Renewable Energy Laboratory, April 22-24, 2022. 54 Design Challenge teams and 23 Build Challenge teams presented to juries, with more than 300 students on-site and over 500 virtual attendees.
This is one of those solar garden lights that draw off sunshine during the day and then turn on to glow at night. Of course, they're not this bright, but a long exposure like this when it's dark outside will make them look much stronger than they really are. It's positioned right at the bottom of the front steps to my house.
For The Sunday Challenge group, who's theme this week was to use a setting on your camera you hadn't used before. I chose the "B" (bulb) setting, which I had never used before, on an old Diana-clone 120 camera. In fact, I'd only ever run one roll of film through the camera and had been meaning to use it again for some time.
For those that don't know about the classic "Diana" camera - they were really really cheap plastic cameras made in Hong Kong in the 1960's and given away as prizes or sold for about .50 cents. That's right - they are super cheap and if you drop one, they might break into a thousand pieces because the plastic is so thin. As a matter of fact, I think mine melted a little on the front because it was kept in a hot car. If you look at mine in the picture below, the melted spot is just above the lens and under the viewfinder.
