Unfortunately it was not a standing seam metal roof otherwise we definitely would of went that path. This metal roof is corrugated on this project.

probably stable grid power cost and supply. also factor in kwh cost. also, use case may not warrant it.

Solar itself is fine. The problem is finding a technician to maintenance them for 25 years. Like most things, the approach is always replace instead of repair. Just look at the HVAC market. If you have a 10 year old system, you will be pushed to replace it if you have the slightest problem.

Did panels 16 years ago have 25 year warranties the way that panels today do? I know there are some today that are warranteed for even more years than that.

In my case. Found they were performance-based warranties so its effectively a warranty against factory defects that would kill a panel within 20 whatever years. The microinverters have a much shorter warranty, and it's not the easiest procedure to remove panels to get to failed micro inverters. For me, a 10-yr payback. But, after years, my roof is now needing to be replaced due to age, so I would need to pay for the system to be removed/installed to get the roof replaced. (still trying to delay that cost/work )

​@@darwinjina normal roofing is good for minimum 50 years. Your problem is you let it be installed on century old roof. Or you must be american who thinks flapping ruberoid on osb is roofing material.

@lauriviik roofs in southern 50 states don't last 50 years. In my area. Shingles are challenged to last 15 yrs due to hail / wind.

Maybe you have been there and done wrong?

@@lauriviik Nice try Diddy

@@Leaderorsheep whats there to try? Very cheap on no mainenance. Panels just sit in my yard and do what they are supposed to do. Think back on your experience and find out what you did wrong, because its opposite of what you are saying.

@@lauriviik - not wasting my time here. Why don’t you install a wind turbine next. Another terrible ROI.

@@Leaderorsheep why should i? I dont have suitble wind conditions for that, nothing more. Strange question to ask. Wind is very location dependant when sun doesnt care about location at all as long as it sees sun.

Most likely direct grid tie so unused goes reverse to the grid but no sun means no solar power and no storage..

Not on this project the comment below sums it up. This system is grid tied and has full net metering so any excess power goes back to the grid and the customer gets full retail rate for the power they produce. This customer also did not loose power enough to justify storage.

With batteries, you have automatic backup. The way things are going batteries are a must.

Customer probably loves microinverters so much on his home and wanted them on his business. I would've went with a DC coupled battery solution for this application. Even a small cache of energy onsite is worth not having to deal with small power fluxuations for business needs. Likely cheaper too, all things considered.

Yup now that’s when I stop watching the video no batteries this just your run of mill ..good video tho from what I saw in the beginning

Pretty sure this adds up to 55kwh not 55.000 kwh which is 229 amps at 240 volts so that must have been a misspeak of 55,000 watt hours.. Pretty sure it is not producing 229,000 amps at peak, be nice if solar was that bad ass..

Haha, sometimes we all lose our marbles! I appreciate the comment, and after watching it back, I can see why there’s some confusion. At the beginning of the video, I was referring to the kWh the system will produce on an annual basis. I should have been a little clearer there. When we design systems, we always focus on annual production. That said, I gave the wrong production number in that instance. I mentioned 55,000 kWh, but it’s actually 59,000 kWh per year. I did clarify it a minute or so later in the video, but I should have cut that part out. We all make mistakes, and I really appreciate the feedback!

This is a direct conversion panel DC to microinverter on each panel AC system so no battery storage.. Lots of wasted solar when the load is not there and no power at night.. having 100 microinverters on the roof means when they go bad someone has to go on the roof and replace them.. That means finding the right one and lifting the panel to change it.. AC on the roof also means higher chances of a lightning strike making it into the building and doing damage.. He did not mention anything about lightning arrestors or if unused power went reverse onto the grid.. By single phase I believe he meant split phase 120/240.. Snow in the Winter is going to be a real bummer..

Thank you for the comment! Luckily, no solar is wasted here. In New York, we have Phase One Net Metering, so all excess power is sent to the grid, and the customer is credited the full retail rate for the power they produce. Over the course of a year, what they produce will be used for this site. The benefit of microinverters is that when one fails, we can use the monitoring system to identify exactly which microinverter needs to be replaced. You’re right, though-it’s a bummer to have to get on the roof, lift a panel, and go through that process. However, the advantage is that the issue is isolated to that single inverter, making it easy to identify and resolve.

Batteries would have been really cool, but we didn’t include any on this project. Fortunately, we still have Phase One Net Metering here in New York, so any excess power is credited at the full retail rate by the utility. Additionally, they don’t experience power outages frequently enough to justify battery storage for this project.

My preference is low voltage DC strings 140v max but not really practical at this size.. The high voltage DC is scary to me but more efficient at size.. Never was a fan of microinverters because now you have DC and AC on the roof along with many active components that may require service.. I believe he said 100 of those things so odds are that someone over the next couple decades will be on that roof several times lifting panels and swapping some microinverters..

Yeah, no MLPEs would be my preference if allowed.

Thanks for the comment Robert. The 460 watt REC module paired with the IQ8X micro, 380 VA rating, has an 1.21 Inverter Utilization Ratio. This inverter utilization ratio is widely acceptable in the solar industry for both residential and commercial and is better than the 1.4 to 1.5 industry standard. A small amount of clipping can occur in ideal conditions with this pairing, but this a drop in the bucket when you take into consideration the non-ideal conditions most of the year. The cost savings, minimal wall space needed, and proximity to the point of connection made Enphase the ideal choice with minimal clipping.

With solar you always speak in potential power when talking about the system.. When speaking of actual daily production then you speak in kilowatts produced.. So this monster had the potential of around 400kwh kilowatts per hour of direct sun.. In actuality it is most likely about 1/4 less in optimal conditions and daily production will vary with time of day, time of year and weather.. I would expect that down the road he will invest in some kind of Powerwall battery system if he is not grid interactive because if the grid goes down your solar goes down as well when fully interactive..

Appreciate the comment and after watching back I am realizing why there is some confusion. In the beginning of the video I am referring to kWh that the system will produce on an annual basis I should of been a little clearer there. When we are designing systems we are always looking at annual production. But at the end of the day I gave the wrong production number in that instance I said 55,000 it is 59,000 kWh a year. I clarified a minute or so later in the video but I should of cut that part out, but we all make mistakes and appreciate the feedback.

When hot it is far lower and can self derate by upwards of 50%..

There is a difference in the inverter capacity, the inverter in the Powerwall Plus is smaller than the Powerwall 3. The problem is the utility not allowing PW3 but there has been some movement on that. If you would like a free quote from us you can reach us at www.nyssf.com ! Hopefully we can help!

Yes look at our page for the full video!

No problem 👍

So we have over 300 panels, 200 are out, our Solar installer solarwork went bankrupt, and now Sunpower, so we are stuck with no installer support or manufacture support. So screwed then screwed again.

If you have micro inverters they are probably manufactured by Enphase which means they would still be under warranty. To make a claim with Enphase you can look at this link here. enphase.com/download/sunpower-system-owner

I need help too!

Me too. Inverter panel isn’t working and I’m still paying the lease.

We contacted the AG in California and his office told us to file a complaint with the California State Licensing Board. There are so many complaints now against solar companies they have a separate form for them.

8k true up 2023-2024 since July 2024 to date January 2025 6 k . My installer went out of business 6 years into a 20 year lease. At ten years 5 years the system was not working and to date, still not working. As a lease customer, we are stuck, with a system that does not work, and only at half power if that. Paid outside company after 30 companies refused to come out and would not help, paid out of pocket, $300. to the only one that did come out and run an estimate of what is wrong and out dated box not communicating to P G & E electric company. I will be looking at 12 k or more in June 2025 true up. Sunpower never sent money for their system not generating for the 5 years. Still paying this lease, as they threatened bad credit report. I am retired now and bleeding out!!!
