  • Twice a year I fill in as DBA when our lady graybeard Oracle DBA takes vacation. This month is one of those times. Yay me.

    For my org, it’s just the massive in-house developed line-of-business application that’s tightly coupled to Oracle. that keeps us chained to it. It’s technical debt from to to bottom, but no one seems willing to start replacing it.

    The new projects typically go with Postgres, MariaDB, or if all else fails, MSSQL. But the Oracle monster in the closet isn’t likely to leave any time soon.


















  • The usable south-facing roof area is full, unfortunately. I’ll have to do ground mount in the back yard and run a bunch of conduit if I want to add any more PV.

    The 32 kWh of batteries are made of two 16 kWh batteries in parallel. Since this system is in lieu of a backup generator, I have it configured to only draw the batteries down to 50%. That leaves the bottom 16 kWH available for emergency use. Basically, for day to day usage, I treat the battery as being half the capacity it really is.

    I’ve only been running this system for about 3 weeks now, but the batteries have been operating between 65% and 90% pretty consistently even running the A/C pretty heavily. They’ve been closer to low 60s this past week, but the wildfire smoke was choking out the sunlight Thursday and Friday.



  • Lol, def can become an obsession. First hand experience there.

    I’ve wanted a whole house PV system for a long time, and this is just me finally getting around to making it happen. SO and I were talking about getting a backup generator installed, but that would have been about $7,000 for something that would only get used two or three times a year since our power doesn’t go out often (we have no heat or ability to cook when the power goes out, and it’s always in the dead of winter when we lose power). The PV system I sketched out was about $9.000, but in addition to covering us during outages, we could use it daily to reduce electric bill so, unlike the generator, this would pay for itself over time.

    SO finally came around to my way of thinking, so here we are lol. My limiting factor is usable roof area. Of the roof that’s south facing, only about 14x20 feet of it is suitable for mounting panels. There’s a west-facing gable, but it’s blocked most of the time by a tree. The east-facing side of the gable is available, but it’s pretty much always foggy in the mornings here, so it wouldn’t add much to the system.

    Unless I build a ground mount setup in the back yard, we’re pretty much at the limit of how many panels I can buy. I’m kind of glad for that because otherwise I’d just keep buying them.




  • All of the labor has been DIY, and I’ve got about $9,000 invested in the system components.

    Back of the napkin math, at current electric rates, puts my ROI at just under 9 years. If electric rates keep going up, it’ll pay back even faster.

    Edit: Depending on how you look at it, ROI could be in as few as 1.5 to 2 years. This system is in lieu of a whole house generator that would have cost us about $7,000. Had we gone with that instead, it would never have paid for itself (other than peace of mind) and we would have been perfectly content. So if I’m only considering the price difference between this and the generator, it’d only have to pay back $2,000.
