Node-RED solar power forecast plus
Using Node-RED's node-red-contrib-solar-power-forecast-plus contribution to plot (light blue line) the estimated max PV generation in ideal conditions for my location/panel orientation/time of year; seems pretty accurate so far. Useful to know what theoretical maximum I have.
DC side surge protection device
Installed a DC side surge protection device to my @froniussolar GEN24 #solar inverter. It comes as retrofit option, installs in under 20 min. A lightning strike nearby can induce damaging voltages in the wires from the rooftop panels 30m away, this SPD takes care of such cases
July solar stats
July #solar stats: 69% of our consumption is self-generated. If we had the 7.7Kw BYD battery (on order) installed, that would have been an easy 100% self sufficiency.
The grim reality of buying anything PV related in 2022
The grim reality of buying anything PV related in 2022, see below the response to an inquiry about a order I made couple months ago. Other sites cite April 2023 for the same product, these guys preordered Nov 2021 and “are optimistic” to deliver this September.. crazy times
Solcast API and home energy usage planning
Fiddling with @solcastAPI; API supposedly provides estimated PV produce based on weather forecasting for a location. Will compare against reality and potentially use to optimize home energy usage planning
Charging an EV 100% on solar PV surplus
Charging an #EV 100% on #solar PV surplus, feels oddly satisfying. @froniussolar
Fronius WattPilot EV charger
The @froniussolar WattPilot EV charger just arrived. This is the 22kW model, we have single phase installation, so max 7.4KW would be available. Can be configured to only charge using PV surplus, and supposedly works with zero feed-in. I don’t own an EV yet,will rent one to test.
A week on solar energy
A week on #solar energy, 70% of our consumption is solar-generated. Battery (BYD HVS 7.7kW) is ordered but 6-8 months to deliver, which I am told is “the new normal” Export of energy has been set to 0%, the inverter regulates production to match consumption. It is underutilized for the moment, but things will change…
PV generation data from the Fronius solar inverter API
Quick and dirty dashboard update to show PV generation data from the Fronius #solar inverter API on our Raspberry Pi home automation status display
Fronius solar inverter and 6kW PV generation
The @froniussolar #wolar inverter is now powered up and working as expected 🙂 Max load test , 6kW PV generation
The final solar panels configuration, 18 Q-CELL 355W
The final #solar panels configuration, 18 Q-CELL 355W Not powerd yet, I will do that tomorrow. Hoping no magic blue smoke is generated
6kW froniussolar GEN24 Primo hybrid solar inverter
My 6kW @froniussolar GEN24 Primo hybrid solar inverter and the DIY automatic switchover box are mounted and wired. Planning on going #solar this weekend 🙂
My @froniussolar Primo GEN24 6.0 kW hybrid solar inverter
Woohoo! My @froniussolar Primo GEN24 6.0 kW hybrid solar inverter just arrived 🙂 It took two and half months after the order, so global chip shortages and high demand are affecting this industry as well. If you try to order one today, delivery times are close to a year now.. crazy times
Seven solar panels on the roof
Mounted seven #solar panels on the roof today, 11 more to go 🙂

Adana kebab
Thank you, Turkey, for the Adana kebab..
Automatic solar grid island mode switchover box
Components for my automatic #solar grid <> island mode switchover box are (almost) here. Now toying with placement and wiring options..

Android statues from its headquarters in Mountain View
Google removes the Android statues from its headquarters in Mountain View. Those were fun, managed to snap a picture of them a decade ago.. https://www.cnet.com/google-amp/news/google-removes-android-statues-from-its-headquarters-in-mountain-view/
18 solar panels and a 6kW inverter
Decided to go for 18 #solar panels and a 6kW inverter instead of 14 panels and a 5kW inverted because the 14 panels I originally planned produce over the recommended MPPT voltage for the inverter,and don’t split well into 2 strings. Learning as I go, should’ve consulted better
Roof rafters under asphalt shingles
Tip for non-invasive detection of roof rafters under asphalt shingles for #solar panels installation:these are clearly visible on an early morning with freezing temperatures. Marked mine with paint and took a ton of pictures at 6 am today,before the sun rises and frost marking go
Fronius Smart Meter
Received the Fronius Smart Meter, it limits the power export of my yet-to-build solar roof installation. Exporting power here is a bureaucratic hell, I will not subject myself to it by zeroing on the export. The inverter itself, a @froniussolar Primo GEN24 5kW due in 3 months 🙁
South-facing slope of the house roof
Sketched the south-facing slope of the house roof to identify where/how to fit the 14 Q CELL 355W #solarpanels I bought earlier (sized 1.68m x 1m), looks like I can fit 4 more panels in the future and split them into two strings. A good site, if you want to do that same thing in…
Sunroom we added to the back of the house last year
Sunroom we added to the back of the house last year totally pays off as it is the favorite place to hang out for all, dog included. The sun and greenhouse effect make it 24*C inside with no additional heating, while outside is below freezing -1.3*C.
Cloud connected geiger counters for Bulgaria
Pleased to see couple new cloud connected geiger counters appear on http://gmcmap.com for Bulgaria the last week. For years my own DIY sensor and another one in the city of Plovdiv were the only contributing to the GMC radiation monitoring community for the whole country.
Q-CELLS DUO-G9 355W hybrid installation
Got 14pcs Q-CELLS DUO-G9 355W, planning a ~ 5kW hybrid installation with automatic grid-tie <> island mode switching with battery backup. The @froniussolar hybrid single phase inverter is impossible to purchase, lead times 1.5+ months.. #SolarPower
