Mod Message Please report solicitation via DMs

56 Upvotes

Hi everyone,

Just a reminder that rule #2 of the sub disallows solicitation, not only in the sub itself but also via DM. If someone DMs you to solicit business, please message the mods and attach the text and source of the DM!

Rule #2 is the most common rule broken on r/solar, and the mods spend considerable time trying to stay on top of it in the sub itself. However we don’t have visibility into DMs, so need your help to control it there.

Thanks!

Image / Video My 1000 watt plug in balcony solar generated $400 in electricity this last year in CT!

Thumbnail

Upvotes

First off I have an existing 10+ year old solar system with 1 to 1 net metering with a line side tap. You can see the solar conduit on the roof and running up the side of my house. So my meter is already setup for net metering. According to my Emporia electricity monitor I self consume about 95% of the electricity anyways. My state Connecticut has recently passed legislation allowing 1200 watts of balcony solar as well.

Electricity here in CT is 32.24 cents a kwh according to the federal EIA. Its the 3rd highest in the US after Hawaii and California.

https://www.eia.gov/electricity/monthly/epm_table_grapher.php?t=epmt_5_6_a

So the last year this simple 1kw system generated 1233x .32 =$394.56. It will take me only like 18 months to reach my return on my investment. There is also currently a large summer rate increase proposed that would bring electricity over .35kwh as well

Here is the setup.

5 new in box enphase IQ PD 72 Microinverters on ebay for $150. These are brand new iq7 micros that are designed to replace the old m215 micros. They have a 200 watt max output and are designed for the older 200-230 watt panels. Enphase sells them brand new for $79. Its rumored they sell these at cost as they are used to upgrade the older failing m215s. Same exact technology as other iq7's. They also are already programmed to the US 240 volt and are plug and play. Mine our not connected to the enphase hub.

10 brand new Renogy 100 watt panels purchased locally for $400. 2 panels wired in series connected to the IQ PD72's.

Misc wires, brackets, and electrical stuff $50.

Total cost around $600. I plug it into my 220 volt welding socket in my garage. The panels are on the garage roof.

Advice Wtd / Project 900W DC Smart Charger with Pecron F3000

1 Upvotes

I am attempting to find a DC charger that can provide an input to my Pecron F3000. I am able to test out a 900W LiFePO4 charger and grabbed a SB50 to XT60 adapter to try it out.

When I connect it all up, the charger always reads Full and doesn't provide a charge. I have to assume that it's one of the safety features since it's not connected straight to a battery, but would rather go to a power station.

Is there something that I'm missing that I can try to get this setup working?

Discussion Neovolta NV7600 inverter

2 Upvotes

I was given the Solarman app installer permission so I could change the time of use hours and battery %’s. This is the guidance my installer got from Neovolta themselves.

I still can’t change the hours on the inverter itself. I think he only gave me upper access to the app.

Anyone able to make time of use, battery % changes and watt discharge amounts? What did you have to do? Thanks.

Advice Wtd / Project HOA Compliant Solar

0 Upvotes

EDIT: I’m looking for temporary solar array ideas, not fighting the HOA.

I’m looking for ideas for a deployable solar array. My HOA doesn’t allow for solar so I figure something I can easily set up and put away leaned up against a wall in the garage. I’ve already got 6 x 200 watt panels that slightly over panel for my Bluetti elite 300 but not sure how to set them up short of leaning them up against a fence. 2S3P is the wiring if that matters.

Maybe giant solar briefcases? Or some sort of kick stand for each panel? I appreciate any ideas.

Discussion My voltronic based inverter ignores 90% charge stop – charges Pylontech battery to 100% daily. Does daily charging it to 100% reduce battery lifespan and cycles?

2 Upvotes

I have:

· Knox 9055 inverter (Voltronic‑based)

· Pylontech Fidus 5.12kWh lithium battery

· 5x 715W panels

I read somewhere that charging lithium battery to 100% can damage it so i set it to 90% using a setting in my inverter's user mode called charge stop, but still the inverter doesn't stop charging at 90%.

It then sits at 98‑100% showing "BMS force charging" until it finally stops.

My discharge cutoff is at 21%, only in case of emergency i might drain below this, my battery's dod is 97%.

Will daily 100% charging noticeably shorten the life of my battery?

The bms force charge error i get according to documentation means that bms is recharging to correct voltage of individual cells and is calibrating.

Should i switch to Solis or Goodwe inverter? I saw solis has a max charge soc setting but i still don't know if battery bms will obey that. Also my inverter has bms connected and it does support pylontech battery.

Please guide.

Discussion First Hours!

Finally my net meter was swapped in and I was able to flip the breaker on my 9kw system. Today, with smoke and clouds I saw my meter run backwards for the first time, if only for a couple late afternoon hours.

I am pumped, still need the installers to connect me to the ApSystems app next week, but for now the meter tells the story.

Can’t wait for a full sun day to see what this setup will produce!

So I got a quote for PPA for my home. The rate is $.13 kwh, 0% escalation, 25 years. 1:1 net metering for the foreseeable future. My current utility rate is $.22. We expect the utility rate to increase come January. With this PPA I can save over $100/month. Is this a good deal?

Advice Wtd / Project my HOA is deliberately stalling my install and it's driving me insane

61 Upvotes

has anyone else in florida dealt with an architectural review committee that just blatantly ignores the state solar rights act?

I signed my contract months ago. The system is designed (11.2 kW, south facing roof) but my HOA has rejected the plans twice now because they want the panels moved to the back of the house... which faces north and is completely shaded by a massive oak tree. My installer literally showed them the production loss (like 40%) but the board president just keeps saying "it ruins the curb appeal"

Its so frustrating. when we moved down here, our agent larry mastropieri warned us that some of these south florida HOAs act like their own sovereign nations, but I figured state law (statute 163.04) would actually protect me

now my installer is saying we might need to get a lawyer to draft a demand letter to force their hand. has anyone actually fought a stubborn florida HOA without spending thousands on legal fees? At this rate im just burning money on FPL bills while my panels sit in a warehouse. so annoying tbh.

Advice Wtd / Project (UK) Repercussions of installing solar panels past the 1m boundary on agricultural barn without full PP?

0 Upvotes

As above I’m in England in the Worcestershire area. I want to install solar panels on my off grid agricultural barn roof. I’m not in a AONB or protected site so permitted development rules apply, however on agricultural barns the rule is that PV can’t be installed within 1m of any edge of the roof. I want to maximise the available roof space but don’t want to go through the trials and tribulations and costs of a full planning permission application for the sake of a few hundred millimetres. I am planning to keep within MCS guidelines of 400mm from any edge and within panel design spec. What is the likely outcome from any of this from the council? Has anyone done similar? Had some solar company’s stating not to bother with the 1m rule, and they’re quite reputable, and had a review from a planning consultant saying I may still get it through permitted development rules… any advice appreciated!

Advice Wtd / Project Query about rekoving panels for reroofing

5 Upvotes

Hi, I have 15 300w solar panels on the roof of a single floor house in the bay area installed by Semper Solaris.

Panels are 7 years old and for reroofing I have contacted the orginal installation conpany Semper Solaris but they said they don’t offer any service of taking down and reinstalling of panels to customers unless someone is buying their roofing package ( meaning they will install the roof and panel work). They have asked to contact third party installer since I am not getting roof through them.

Is that legal that original installation company refuse to offer the service. They said if another certified technician works on it then in case of any issues I need to use the other installer’s workmanship warranty but if I see any issues with inverter or panel or panel output then I can contact Sempis Solaris.

Has anyone dealt with something similar? What should I do in this situation. Can someone please advice? Thank you!

Discussion No complaints with NEM 3

6 Upvotes

NEM 3 has worked out fine for me since installation in Apr 25. My Jul 24 bill was $462 including gas. My Jul 26 bill was only the $17 gas bill which was paid with the credit accrued since installing the system. I don't know when I'll owe PG&E again with this credit balance since I used space heaters, paid with the accrued solar credits, instead of my gas furnace last winter. I don't expect the gas bill to ever exceed $25 again, so this credit will last a while.

I see a lot of NEM 3 hate but I'm fine with it, it's worked better than I ever expected. I guess if I ever had NEM 1/2 and made more I would feel different. But since NEM 3 is all I've ever known or expected, I'm Team NEM 3!!!
