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 🙂
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..
M10x200mm hanger bolts for roof mounting my 18 solar panels

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
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 🙁
LoRaWAN node with a solar harvesting module
Testing a #LoRaWAN node with a solar harvesting module. Sending temp and batt once every 5 min @ SF7. Node is placed near a north facing window, it is showing and completely overcast. 1800 lux measured by phone. Recording battery readouts, will post them in few days. #IoT
Solar harvesting LiPo chargers
Just ordered one of @jrsikken's Solar harvesting LiPo chargers, looks promising https://www.tindie.com/products/jaspersikken/solar-harvesting-into-li-ion-battery/
My solar water heater (220l) reached 79*C
My solar water heater (220l) reached 79*C yesterday #summeriscomming

DIY swimming pool solar heater
A DIY solar heater for our 13m³ Bestway pool out of 16mm LDPE pipe – getting the water past the 25°C mark more days of the year.
Smart IoT solar hot water tank controller
A smart IoT controller for my solar hot water tank – mode switching (manual/auto/anti-freeze) driven by an emonCMS feed.
Video of the LTC3108 energy harvesting board with solar cell
Video: the LTC3108 energy harvesting board pulling power from a solar cell lit by a single 23W CFL a meter away.
Using the LTC3108 breakout board with a solar cell
Charging a 1F supercap from a scavenged solar cell through the LTC3108 energy harvesting board – first light, wrong cell, lesson learned.
Solar water heating in the winter
Winter mode for the evacuated tube solar heater: plumbing disconnected, fingers crossed, electric element on standby against freezing.
Solar statistics
Statistics from my 440 Euro 220l evacuated tube solar water heater – what the self-installed rooftop system actually delivers.
Solar Funky
Stuffing a Funky into a one-euro solar garden lamp – free enclosure, free NiMH battery, free charging. Solar-powered wireless node.
Finding good use for excess solar hot water
My 220l solar tank hits 85°C in summer with water to spare – finding good use for the excess hot water and trimming the electricity bill.
Measuring the solar yield
Measuring the actual solar yield of my evacuated tube collector and comparing it against the calculated available energy in emonCMS.
Thoughts on the Solar Energy Calculator
Refining the solar energy calculator – an emonCMS input processor now derives momentary yield from the tank temperature rise.
Calculating the available solar energy and logging it to emoncms
Calculating the Sun’s position and available solar energy for my 2.088m² evacuated tube collector, logged to emonCMS as a baseline.
Using the Sensing Shield for logging solar hot water tank temperatures to Pachube
An expandable solar hot water tank temperature logger to Pachube on the Sensing Shield – built for a forum guy new to Arduino.
