Good PPA?
I made a previous post here about my house's potential for solar. https://www.reddit.com/r/solar/s/cpwjdS0FIH There was some great feedback, but I only just started exploring my options. Someone came by today through mass save to give a quote/offer. I did not know he would be pushing a PPA so hard, as I generally think owning sounds better. I attached what they offered to the post. 0% escalation sounds nice, but it's not clear what a similar cost would be to own, since I want to compare that with possible financing rates.
My small solar shed, please give me input/correction on this abomination
So the layout is as follows: 6x 585w bifacials in serial > 8 meters > small steel shed (8x10). Connect to Datouboss 5500 inverter, which connects to eaton breaker panel 6 circuit. Separate neutral and ground bars. Circuit goes via thwn (in conduit) 8ga to outdoor outlet box with 2 gfci outlets to run exterior loads in garden. The datouboss is connected to an ecoworthy 48v 100ah rackmount battery, via 8guage wires, with a 150a t fuse. Closed loop (comms to inverter). Questions. Am I missing anything?
Adding more capacity
I have an 18.86 kw system currently. 41 x 460W panels, IQ8X microinverters and an enphase combiner. It's my understanding that the combiner will accept 9 more panels and inverters. Ultimately, I want to get as close as I can to 25 kW system (my state's limit), but I also want to be practical. 9 panels seem easy, and get me to 23 kW. Would the extra 2 kW ultimately require a second combiner and ultimately make it cost prohibitive? I use about 27000 kWh annually, submitted by /u/Cultural-Ad4953 [link] [comments]
Huawei 22KT-S0 question
Hi all, I am based in Belgium and received today a quote for car charger. A Huawei 22KT-S0. The quote was 2404 Euros for charger, installation, labor, material etc. Price comparing with my 12 panel and battery installation seemed a bit unreasonably high to me. My question is: I found it on retail price of 529€ instead of 850€ that the company sells it. Will I have any issues with guarantee and control technique inspection if another authorized electrician installs and sets it up? PS: I already have a Huawei inverter along with EMMA.
Solar Production & Energy Consumption Monitoring Without Expensive CT Clamps
I wanted to share what I accomplished using a Raspberry Pi 5 running Home Assistant and my existing smart electricity meter. I have an Enphase solar system, but never had the consumption CT clamps installed in my electrical panel. Instead of paying for additional hardware and installation, I connected my Xcel Energy smart meter (Itron) through its Launchpad program and integrated the data into Home Assistant.
Buzzing from fuse board/consumer when solar output is high — anyone had this?
Hi all, hoping someone has come across this. I recently had solar and a battery installed. The fuse board is in my office, and I’ve noticed a fairly loud buzzing when solar output gets above roughly 5–7 kW. The battery was full, so I think most of the excess was going back to the grid. Today I heard it again, checked the app and saw the panels had gone above 5 kW just as the clouds cleared. The installers have already replaced the new 32 A solar breaker and said they tightened the connections, but the noise has returned.
Solar PPA panels stopped working, company refuses to fix them
Inherited a solar PPA when we bought our house a few years ago. We were in year 11 of a 20 year lease. Worked great for the first year and a half. Usually electric bills were only about $20/mo. Got one for $100 during a particularly hot month. The PPA is $250/mo so not bad in a 2500sqft house. Then the bills started creeping up. After year 2 we got a reimbursement check because the panels underproduced by a decent amount. One month we got a $600 electric bill and we contacted the solar company and the electric company.
