Sunrun We were deceived San Fransisco California

The neutral lead is the one that melted.  the hot side was OK.  I have a letter on company letterhead from the licenced electrician stating this.  A copy was provided to sunrun.  I am not just stating "whatever" for effect.  They reimbursed me for the electrician ($75) after a few months.  Obviuosly, they were convinced there was an issue as they paid me back and sent their own person to supposedly make a permanant fix.  It only took over a year after notifying them and going through the trouble of hiring an electrician and filing online complaints for them to send one.  I still, to this day, do not know what "repair" was afforded as I was not home when the person showed up. 

The system installed on our house is only a 3KW one.  I do not know what the weather is like where you live but it is over 100 degrees here for 2 weeks straight and our AC runs a lot.  I am in my 4th round of talks with sunrun and they are really taking their sweet time "talking" about what to do to make this right.  Been over 4 years now!!!!  Initiated this last round 3 months ago!!!! Like I said, stonewalling.  Glad you are able to get savings with your 8KW system. 

I went back in our records and found our power bill in 2010 (BEFORE activating the solar) was over $2700.00. Last year, with the solar it was $1300 for the year.  This is even with the ever increasing rates from the power company. 

Hang in there..you WILL see positive results.

I've had an 8kw system from SunRun since Sept 2010 and it's already starting to payback..not a lot, but it won't be long before we're looking good.  Our bill from April through Sept. is about $8.00 to the power company and an equivalent $90.00 to Sun Run.  Prior to the system going in our summer power bill was almost $300/month during the summer. I also must run medical equipment 24/7 and that quickly adds up.  I have been VERY satisfied with their service and responses.  I believe them to be an honest company.  You should have received a power plan summary when you purchased the system.  Are you generating (solar) approx what the chart shows?  What is the size (kwh) of your system?  You can also look on their website and see your production versus expected production.  How is that doing?  Their website is VERY informative on system performance.

I don't know what you were really "told", but you just don't immediately start making money with your solar.

Do your solar panels need cleaned? Has the production dropped?  How did the wiring melt due to too much current through the breaker?  The breaker is there to protect the wiring and will trip at rated  capacity no matter how many wires are connected to it. If the breaker is 20 amp, it will trip a bit over 20 amps, no matter the number of outlets or wires. If, they connected a 14 gauge wire to a 20 amp breaker, it could present a wiring problem. Utility circuits (kitchen, laundry, etc) are usually 20 amp with 12 gauge wire.  Other household circuits are usually 15 amp with smaller 14 gauge wire.  Did your electrician install a double 120 V breaker to fix the problem? That allows an extra breaker position in your electrical panel.

Again, hope you can work it all out.  I'm very satisfied with the service. 

No, I DON'T work for them only subscribe to their service.  It's nice to know if something fails or the panels get broken by hail, that they will take care of it.
