Finally got around to switching to Octopus Flux, which gets us cheap electricity to charge the batteries during the night. Of course, the day it goes active we get glorious sunshine and now I have a full battery but nowhere to store the solar. shakes fist at sun#solar#solarpower#batterystorage#renewables
Yesterday I let my bot manage the inverter charging and discharging for the entire day. It did quite well! Our entire electricity demand was met for less than zero cost with solar and automated load shifting on the Octopus Agile tariff. #solar#renewables#solarpower
"The idea that solar power could interfere with the UK’s food security is utterly detached from reality. Solar power generated over 8% of all our electricity this spring, but takes up less land than golf courses."
Better idea than banning solar panels on potential farmland - turn all the golf courses into community gardens and allotment sites.
Generations of solar panels: installation upgrade, nominal 63W to 375W. The old panel that served for around 30 years was still working, but a bit low-powered. De facto output seems to be around 6 times higher as well for the new one. The Victron system is also good at teasing out power despite some clouds.
The most annoying part was when I messed up the ”no tools needed” MC4 connectors and had to drive to get a new pair. #offGrid#solarPower
An impressive curve! South Africa is experiencing an influx of solar panel imports, totalling about $650 million (equivalent to R12 billion) in the first half of 2023. These panels amount to approximately 2200 MW of solar energy. It's great to witness the accelerated shift towards renewable energy :apartyblobcat:
Scientists Beam #Space-Based #Solar Power to Earth for First Time
"#MAPLE’s array of transmitters successfully beamed #SolarPower collected in space using #microwaves to a receiver on the rooftop of Gordon and Betty Moore Laboratory of Engineering on #Caltech’s campus in #Pasadena."
First week of solid spring solar power production! Hoping for many more. At this rate we'll produce well over 1MWh per month through the summer and the first part of autumn.
🌞 Sonnige Aussichten: Am 𝗦𝗮𝗺𝘀𝘁𝗮𝗴 decken Photovoltaikanlagen in Deutschland etwa 𝟯𝟰% des gesamten Strombedarfes.
Im Jahresdurchschnitt waren es letztes Jahr 𝟭𝟭.𝟴% (🔍 energy-charts.info), heute ist also sehr viel Solarenergie im Netz!
Wenn du deine Haushaltsgeräte über die Mittagszeit in Betrieb nehmen kannst, dann kannst du sie mit der Kraft der Sonne versorgen. Bist du Mittags nicht zuhause, kannst du vielleicht am nächsten Tag viel Wind am Abend nutzen oder z.B. das Wäschewaschen auf einen Tag verschieben, an dem du zuhause bist.
Solaranlagen werden übrigens oft nicht mehr nach Süden hin ausgerichtet, obwohl in der Himmelsrichtung die Einstrahlung der Sonne am höchsten ist. 🤔 Stattdessen neigt man eine Hälfte der Panels nach Osten und eine nach Westen. 🧭
Dies hat den Vorteil, dass man den Mittagspeak abflacht und in die Breite zieht. So wird der Zeitraum verlängert, in dem die Energie der Sonne genutzen werden kann.
Durch die gefallenen Kosten für Solarzellen in den letzten Jahren ist diese Ausrichtung auch bei privaten Anlagen auf entsprechenden Dächern inzwischen wirtschaftlich. Ebenso steigt die Autarkie vom Stromnetz und ein Stromspeicher kann kleiner dimensioniert werden. 🔋
Doch auch ohne eigene Solaranlage kannst du dadurch länger grüne Energie aus dem öffentlichen Stromnetz nutzen. 😉
Ich finde es erstaunlich und sehr befriedigend, dass selbst unsere popelige 600W-Solaranlage es in den Mittagsstunden oft schafft, nicht nur unseren eigenen Strombedarf zu decken, sondern sogar noch etwas ins Netz einzuspeisen. Ich freue mich schon darauf, wenn wir endlich die volle Leistung von 800W freischalten können.
Wczoraj lało, dzisiaj lało, ale nareszcie jest 🌞 Temperatura? Lepiej nie pytajcie, ledwo 15 stopni. Ale zawsze trochę prądu ze słoneczka wieczornego do aku nałapię ;) #Wyprawa2023#solarpower#BikeNomadOffgrid
My electricity bill for last month: Import costs ~£50, export credits ~£90. Overall credit for April: £40 (including standing charges and running an electric car).
This is thanks to Solar PV, a House Battery and a flexible tariff from #Octopus (Intelligent Go) - all orchestrated with #HomeAssistant
Capital cost was high but well worth it 👍 #solar#solarpower#battery#solarpv#lowcarbon
Solar PV capacity still chugging along at +4 GW/year in the Netherlands, reaching 24 GW by end-2023. That's 1.35 kW per inhabitant, and way above the national peak demand (~18 GW)
Fed by generous government support, including continued net metering for residential systems.
I don't plan on touching them whilst grounded so I'm not too concerned, but I am now wondering if I can just put up an antenna and steal power. Screw solar and wind, our house will be powered by MEDIUM WAVE BABY!
My solar panel system is ready for testing. Two "6V 3W" panels connected in parallel. This weird backplane is connecting them using the ancient Chinese technique of hot glue. Using that screw I should be able to mount them to something.
Initial measurements show that this gizmo is making 180mA at 6V (~1.1W) with light clouds.
I'm waiting for a USB current meter, and soon I should be able to continue my "powering Raspberry Pi Pico" blog series.
How much did the solar eclipse whack our solar power generation over in California, three time zones away from totality? A significant amount, it turns out. Monday was the eclipse, Tuesday was a regular sunny day. #Eclipse#SolarPower
“The rapid growth of solar power led to a record-breaking year for clean energy generation in 2023, and the year is expected to mark the start of a long-term decline in fossil fuels”
