Owning Your Own PV System

[gadfly56]

Yeah that's about what mine was. Probably anyone doing it themselves and not counting their labor, would be around there for a simple payback. I have always been surprised that More sparky's don't put in solar.




Just a bucket of electrons sitting there in the garage....had the cat tip it over one time, man that took a like time to pick up, those things are small!

Geez, just use the electron vac next time.

Off grid is not an option. The thought was in a prolonged outage the PV array would provide power and charge the batteries during the daylight hours. Are you saying that this type of system is not feasible?

It's certainly technically feasible but the cost can vary drastically depending on what and how long you want to power. But for extended outages you should have a multi-fuel generator because there isn't always enough sunlight to adequately recharge batteries and power loads or the temperature get too low to prevent the (lithium based) batteries from working.

8kW average would be 192 kWh/day or 70,000 kWh/year. Not plausible for a normal single family residence unless something is very wrong.

I believe what was meant was that an 8 kW PV system would be expected to annual generate about the full annual consumption at the time of PV installation, but a 12 kW PV system was installed. The rest of the post discusses how the excess generation was then utilized.

I’m going to guess that 8kW is peak demand
That sounds better

Who knows?

Sorry it was early. I use average 8000kWh per year and my system makes average 12,000kWh per year.

I am allowed to send excess production to anyone in my Utility's area.
This is called Schedule Z net metering credit transfer...

A Schedule Z form is used to transfer net metering credits to another account with the same electric company and within the same ISO-NE load zone. This can be done to share savings with family and friends, or to donate the benefits of renewable technology to other entities.

That's cool

A shockingly reasonable option. Some bureaucrat was punished for this actually helpful regulation, I'm sure.

This is what I thought so for my current needs PV is not worth the effort. If I were building a forever home it would probably be worth it.
