https://www.ebay.com/itm/XXX/124431577755 This is the cheapest I've seen it Keep in mind that every time they have a sale, which has been happening every couple of weeks or so, the price keeps going lower and lower than previous sales. It doesn't seem like the solar business is doing too good

Doesn't have breaker or ports but relatively cheap for 5kwh https://www.ebay.com/itm/145738275941

I washed my panels and it resulted in 8-10% higher production. (only wash your panels in early morning or at night. Don't wash when the sun is beaming on them) It makes me wonder if a misting system to use once a week would be a good idea

https://www.ebay.com/itm/325962859986? This place seems to be a solar company. They also sell used panels Makes me wonder, if you can get top of the line high power bifacial panels for $0.27/watt, why are we buying used panels from Santansolar for $0.10-0.25/watt? Much better to go new at...

Santansolar is having a sale on some of their panels. The sale says buy one get one half off on all used panels, but the code only works on some of their panels. It might be a glitch. But it stacks on top of sale panels. There are a few panels between $26 to $30, around 250W each. That comes out...

Is there any resource that gives a step by step tutorial for adding batteries with links to the needed parts? I've come across a lot of info that Will has, but it's more of a test video, or older videos of batteries, or smaller van systems, etc. And most of the videos and posts leave some...

MPPT: max 15A 600V Panels: used panels (let's say degraded to 200W) Open circuit voltage (VOC): 48.7 V Max power voltage (VMP): 41.0 V Short circuit current (ISC): 5.99 A Max power current: 5.61 A Let's say I have 8 panels in series right now. I want to add more arrays in parallel. Can I...

What happens if I don't ground the solar panels? Just realistically speaking. I'm in an area that rarely if ever gets lightning. I'm putting the system together little by little. Haven't set up the inverter yet

I'm trying to use these for my 50ah 48V batteries. There's 3 listings for same specs. I'm not sure which is better. Which one is better for batteries? https://www.amazon.com/gp/aw/d/B0C4364ZN7/ref=ox_sc_act_title_2?smid=A3VVXZCJ717A91&psc=1...

Can anyone help me figure out how to get a Raspberry Pi and install Solar Assistant on it? And how to connect it to my AIO inverter? Thanks

I have an array of panels and it's been working good for a while. I decided to parallel another set with the first one. So it's the same number of panels and same kind of panels. Here's the issue. On the first set, let's say the male connector is the positive. But on the new set, the female...

Has anyone tried these mounts? They're about $12.65 per bracket. You need roughly 2 per panel, and it doesn't include the rail system so you have to get a separate rail system. Maybe Will can do a video? I'm willing to be a 'Guinea Pig'...

Hi everyone. I'm a beginner needing help. Setting up a DC system seems pretty straightforward, but I can't figure out how to wire an enphase system. It's not very DIY friendly to wire it Seems like it has a proprietary wiring system. Where can I get the cables? Is there a cheap way to wire...

Assuming I have the wire size figured out already, how can I connect the PV array from a flat roof to the inverter? If I use PV cable all the way to the inverter, do I need to run it inside metal conduit? Can I leave it exposed without conduit in high heat area? Would something like this...

https://www.amazon.com/gp/aw/d/B0D7ZW4BNC/ref=ox_sc_act_title_1?smid=A3KD4665HYA5OD&psc=1 They claim these protect exposed PV cables. Obviously conduit is better for longer runs, but can these be useful for small distances of exposed PV cables? Sometimes there's a few feet of cable that's...

I know it's not an ideal situation to have a size mismatch, but let's say for whatever reason you have regular clipping for an hour a day. Would this wear out the inverters faster?

Where's the best place to get some hoymiles microinverters?

Hi everyone. I'm new. This forum is a great resource. Can you please help me with the wiring? Just want to make sure I'm doing it right. Equipment : IP6048 inverter, 2 MPPT, 125-550V, max 6500W 2 strings of panels in series (no battery for now, maybe down the line) This is my plan step by...

Not sure about the quality of this company. But seems like they have a US location and at least some of their products are UL. 10 AWG PV cable, no connectors, 50ft black and red for $22 ($0.22/ft) https://www.amazon.com/gp/aw/d/B0C85M97CZ?ref=ppx_pt2_mob_b_prod_image 22 pairs PV connectors...

What's the easiest way for a total beginner to mount panels on the roof? Will doesn't really have any information on DIY racking or installation and I think many beginners can benefit from a discussion. For my specific situation, I have a flat untiled section and a tilted tile section. I also...

I narrowed it to the following 2 paints to paint the edges black. UV resistant and direct to metal paint. Any thoughts? https://www.amazon.com/gp/aw/d/B00JQVTOJC/ref=ox_sc_act_title_1?smid=A1WTQLQ6IT4G74&psc=1...

I'm sure some of us have a few extra panels that didn't fit for whatever reason. Is it better to just keep them as backup, or to add to an array at a less ideal setting? For example, let's say you have ten 100w panels in series (just making up easy numbers). You can add an 11th one that is...

I've watched most of Will's videos multiple times. He makes it seem so easy. In all of his videos, he's running the PV cable directly from the panels to the inverter, without any conduit, just bare PV cable, over his dirt backyard, over concrete, inside, outside, in his shop, RV, everywhere...

I've seen Will Prowse do this. He used a NEMA connection to connect his inverter to his electric panel. He wired the end of a NEMA plug into the inverter and then just plugged it in I like this idea because it will give me flexibility to move my inverter to different subpanels based on how I...

Any thoughts about this? There's multiple ones on Amazon for $20 https://www.amazon.com/gp/aw/d/B0DBVMSNJ2?ref=ppx_pt2_mob_b_prod_image

I have some experience with solaredge, enphase and tesla systems in the past. I don't really see any major enough differences between them, so for my latest system a chose to go with the cheapest, which was Hoymiles grid tied in my case. I want to be prepared when the terrorists attack the...

Anyone know what's the best way to mount panels on the side of a house over a balcony? It will not only be a balcony cover, but will produce electricity. The panels are fairly heavy at 56lbs. Could be something that mounts them on a wall but out about 6 inches to clear the roof, or could be some...

Before you grill me, this is a temporary set up because I'm missing a couple of parts. I have some ground mount panels in a series. One of them has shade at the bottom of the panel for about a third to half of the day. Please see the picture depicting the shade. Is it better to leave that...

Let's say there's 3 strings in a parallel set up. Is there an easy economic way to be able to monitor each string's production?

I've narrowed it down to these 2 panels. Similar priced around $0.20/watt for used panels from Santansolar. I'm assuming 10% degradation for both. The volts will work for my application both ways. (Bluepower ip 6048 aka MPP LVX6048 WP, 1-2 strings, shading issues in morning ) Sunpower 230w at...
