Solos Solar Array production stats - March 2026

solominer (81)in #solar • 2 months ago

The sun is ramping up again for the year, and I am capturing much of its light. We set another record for March, even with array-C in a degraded state. Finally got over the 2 megawatt hour threshold. I am still working on issues with that one string. Seems my fixes did not resolve the problems. So I am still troubleshooting to figure out what is the cause. @txracer recommended adding insulation to the connectors so I may try that next. In the mean time I have done continuity tests on the wire ran into the building. And also separated the paralleled PV connection so I can troubleshoot them separately. One by one I am isolating components to hopefully find the fault. Next is to try replacing the circuit breaker out by the degraded string. Hopefully I find the issue soon, sucks only being able to run one Bitcoin miner right now. But I hope to have all that fixed soon.

In the month of March we produced 2010.6 kWh (2.00 Mwh) on the farm.

A new record for solar production!

Using excess solar power the farm mined 0.00012011 Bitcoin valued at $8.19 based on the current Bitcoin price of $68,250

Mining hardware: 2x Bitmain Antminer S21 Pros running at 7200 watts. Only one was in use for March due to array issues.

I hope you are able to get it figured out fairly quickly. It's definitely a good time of year to be capturing those rays! I got myself a nice sunburn on my arms watching softball on Friday.

Thanks, these kind of problems are pretty normal in my projects. Helps me learn a lot along the way.

Hah yeah I am wearing my sun hat a lot outside now.

I hope you can figure out the issue there, it really sucks having an investment into the panels/cables/batteries/ and wiring and not get your maximal ROI. I guess some BTC from the solar power is good BTC. Now when that goes to $200K you'll really have some better value!

With any luck you'll have another miner up soon. Trouble shooting these kind of problems is always a nightmare. It's even worse if you have to get an electrician involved... Good luck!

Me too, it sucks not being able to run it at full power right now. But with every time I go out there and work on it I isolate a little more of the problem, so its all progress I think.

Yeah stacking those BTC will indeed be worth something some day, just does not make sense to sell them as soon as I get them at this price.

Thanks much, I do hope to get fully up to speed soon.

2MWh for a month is great. I've seen a big difference between February and March, but that is to be expected. I need a couple of months of good exports to get me into credit with the power company :) My system has been working well with no issues for a while, but I guess yours is more complex. Hope you can resolve any niggles.

Shine on!

Yeah it was quite impressive, it has been getting brighter out here and the days are getting longer.

That is an interesting idea of selling back to the grid, though where I live its not really worth it. I am guessing it heavily depends on the region, well glad you have something to do with the excess power.

Yeah well I built it myself, and since it was my first array I did all myself something probably needs to be improved. So once I figure it out, hopefully I will be better prepared for next time it happens.

Thanks!

I'm sure you've learnt a lot from the experience and you get to share it here. I left it to the professionals. We get quite a got rate for export, so that offsets the cost. I wouldn't have spent this much otherwise.

qué bien que publiques estos datos porque a veces uno no se imagina todo el mantenimiento que lleva un sistema off-grid
un gran saludo por allá y espero que el clima de primavera te siga ayudando a romper más récords de producción este año

it's great that you publish these data because sometimes one doesn't imagine all the maintenance that an off-grid system requires
a big shout out over there and i hope the spring weather continues to help you break more production records this year

Ah glad you enjoyed reading my updates, yeah I figured I should report what is going on as I produce my stats as well.

Thanks!
