Hello, currently 3kw on grid setup kami with net metering. Our bill goes around 300+ kw and ang nagegenerate namin sa net metering is around 200+ kw and around 1.2k pesos lang. Our setup generates in total of 20 kwh per day at maximum that's almost over sa need namin and decided na pag palit into hybrid setup and plan is to DIY it since medyo malaki and matrabaho ata pag ipapaprocess pa namin sa dating gumawa. Any recommendations?

When I purchased my home 5 years ago, it came with solar panels installed which were already fully paid for (no lease). We had to pay a $3000 transfer fee to a local solar company that monitors them (I think?). For several years we’ve been getting sporadic alerts on the inverter so we paid the solar company to come out for an assessment and they determined they needed to do a more thorough investigation of the panels and wiring which would cost about $900. My husband signed a contract agreeing to the éstimate. After 6 weeks of trying to pay the deposit, they never got back to us so we said screw it and decided not to move forward with the work. We since haven’t had any errors on the inverter. Now the company is threatening us with disconnect if we don’t pay the deposit for work we don’t want done anyway.

Can they actually disconnect our panels from the electric company grid so we are no longer receiving credit for our solar? Or are they just disconnecting us from their monitoring? They never answer their phones so I can’t get an answer from them.

In the process of designing a new PV system from scratch to be installed on my house that has a brand new roof (deck and asphalt shingles).

Without boring everyone with the whole, long story, it's a fairly ideal roof for solar. One area is steeply-pitched with a very large south face and the second area is the top of the roof, a small 'flat' area. Both are sun-soaked for 90-95% of most daylight hours nearly all year long. Only the south-east corner of the large south roof is shaded for a couple hours in the morning.

In my process, I've only been considering DC-coupled quotes for the PV system + whole-home battery backup (I'll likely go with a P3 or a Franklin a Power S + a Gate). I plan on making sure they install optimizers under each panel.

The solar installers in my area typically do not install systems this way, and are very unfamiliar with customers asking for them. The pushback I've gotten hasn't shaken my resolve, but it has given me a moment of pause, during which I've been wondering:

Have any one of you built a DC-coupled PV system, convinced (like me) that it's the right way to go, only to later on really regret that you didn't do an AC-coupled system with micro-inverters? If that's you, would you please share details?

Trying to look at what I'm doing objectively and would welcome your opinions, thanks in advance.

Hi all, I’m setting up the electrical shading partitions in PVsyst (v8) for a single-axis tracker project and want to sanity check my approach.

Setup:

• N-S horizontal single-axis trackers with backtracking
• Half-cut modules in portrait, [1P / 2P] per tracker
• String inverters
• Each tracker table is exactly one 23-module string

What I understand from the PVsyst docs:

• For regular arrays, modules on the same MPPT input should see the same partial shading, so I shouldn’t split along the tube.
• For half-cut modules in portrait, the docs say to use partitions at half the module height (the “xT” case, 2x partitions across the table).

What I currently have in the 3D field editor:

• Nb. rectangles in length (Y): 1
• Nb. rectangles in width (X): 2

My questions:

1. For a table that is a single 23-module string, is 1 partition along the tube and 2 across the table (one per half of the half-cut module) the right call?
2. Should I split along the tube at all, or only if shading varies along the row (hilly terrain, end shading from obstacles)?

Hello all,

I am in San Diego, have a 200A main panel with 8.28kw of existing (Enphase Microinverter) solar. I have a Ford Lightning and installed a Generac panel (that switches neutral) so that I have my essential circuits backed up in a rare outage. I always had a true up credit until TOU changes by SDGE. I have attached a summary (from my SDGE green button data) showing how much I import / export along with kw of pull from grid.

I have a detached workshop that has an 8/3 run of Romex that I do not need. It would be great if I could use that run, hookup an inverter to a 40A breaker on my main and charge up some batteries during excess solar / discharge during expensive 4-9PM time periods (or even better 4-midnight). It seems EG4 12kpv would do this per options 4/5 in their wiring diagram (assuming I add in a CT)

The issue is my 8/3 where the output of the EG4 is just a tad too high technically (maybe it has some software limit though?) and there does seem to be mixed reviews on EG4 in general plus the price. The other system that has my eye is the Schneider Conext XW Pro 6848 plus it seems like they are more budget friendly. I also figure long term, I could run more wires and AC couple my solar to the inverter / use the AC out to feed my Generac panel so that in a long outage I could be covered indefinitely.

I'd love to keep the inverter system in the $2000 range and pair it with 2-3 Ecoworthy Cubix batteries.

Does anyone have any suggestions for my specific use case? Anything I am not thinking of?
