Solar - 8kW Hybrid Inverter w/10kWh (upgraded to 20kWh in Sept. 2022) ESS/battery (not DIY)

[KhunLA]

Solar production past 3 days has been just OK, and looks like the next week, probably 5 to 7 of the next 10 days, is going to be the same.

 

 

Good .. not brutally sunny & hot, and no 'feels like' 5-10+ degrees added to ambient temp.  Can actually get by with just fans, although still enough produced to run the ACs, if not too abusive.

 

Bad ... takes a good part of the day to recharge the ESS.  Instead of topped up before 1000 hrs, it's taking till 1400 hrs.   Although you can tell when I charged the MC.   Got back from the park with the dog just as it started to drizzle a bit of rain.

 

 

Also backed a Cheesecake for about 1 hr worth of appliances, and wife on the sewing machine, all day.   Certainly not charging the car, though don't need to.

 

The rain part is, just an annoying (if on scooters) drizzle now & than.   Shies are almost 100% clouds, light, allowing sun through, to very ominous dark gray, but not much rain.

 

A bit better than overcast & heavier rain, as that would probably knock production down to 10 ish kWh a day.   Needing 6kWh over night, if minimal AC, or just fan on, while sleeping.

That forecast is spot on ... again.   Another gray day ahead.  Although, already producing a bit more than using.  That's with 1 AC going in the bedroom.

Sadly, our Solar System has hit a milestone, with our digital meter, installed about 2 weeks after Solar was installed, and almost 25 months to the day, on the digital meter. 

 

It broke the 1000kWh mark ... 

That's the same, as a few of our one month Solar production & consumptions numbers.  Took 25 months instead of 30 days.

 

So not quite 'off grid' ... average 40kWh a month, for ~฿130 a month.

 

 

Damn overcast skies & owning a BEV car.  Somedays, you just got to use the grid to charge the car.  Like today, since overcast this week, haven't bothered.  Then the bank calls and tells you that your visa extension paperwork is ready.   Say what, only took 3 days instead of a week.  Oh crap ... got to charge the car.

 

And now, charging, as ran it down to 28%, going to Imm office about 250kms R/T.  And plan on going O&A tomorrow 🙄

 

On the flip side, have produced 16+ MWh & consumed 15+ MWh.

For a saving from PEA of ~฿64,000  without even considering the petrol savings of what it would cost for 17k kms worth of liters of 91 @ ฿36 (~฿43.7k)

 

 

Guesstimate would be about 250kWh went to house/inverter, average 10kWh a month & 750+ going to the BEV (car), average 30kWh a month.

If planning on having Solar & BEVs for transport, then size you system accordingly, if wanting to be almost off grid. We did not, but have plenty of excess solar ... usually
