Solar Panel System Net Metering With Actual Data
Рет қаралды 40,278
Күн бұрынThis video shows how a grid tie solar panel system with net metering works using actual data from my system. I show how the solar panel system payoff period changes dramatically based on having net metering and which type of net metering your utility offers.

Without batteries you only have an illusion of an infinite battery. All the state has to do is change the laws that regulate either you or your utility and you can be profoundly impacted. It would seem that it would be far better to divorce totally from the grid and eliminate your bill altogether rather than going into debt to halfway participate in alternative energy production.
@ProjectsWithDave 2 жыл бұрын
That may be true, but if you can't afford batteries, I think it's better to participate at some level than not at all. That's one of the reasons I targeted a six year payback, it lowers the risk of something changing to impact my return on investment. And it is also the reason I didn't borrow money to pay for the system.
@FarmingUnclear Жыл бұрын
I'm installing solar only. When the law changes, I'll get the batteries installed later. If the law doesn't change, I won't buy the batteries. It's nice to have the flexibility of doing the system in two parts versus all or nothing.
@william693850 Жыл бұрын
@ProjectsWithDave Yeah that's true and something to consider. Though if you have any type of power outages your system fails to produce any power for you or the grid until the power comes back on. I guess you would have to consider how many times your power goes out and for how long. Mine goes out frequently for hours to some times days.

This is an exceptionally well-made video. Your data mining and logical presentation made this topic crystal clear to understand. I recognize that net-metering is a very real consideration for anyone trying to decide if solar will work for them...and that is a huge problem. The availability of net-metering, or lack thereof, is often THE deciding factor in whether or not someone installs a solar array. They aren't doing it to reduce carbon emissions or, perhaps, "save the world" by getting their power from some place other than fossil fuels. When someone goes with a grid-tied system and intentionally avoids getting any kind of battery backup, because they can rely on net-metering to still provide a reasonable ROI, what they are effectively saying is this is a financial decision above all else. It is this notion of "ROI" that undermines the adoption of solar, with net-metering specifics contributing to that problem. There is never a wrong time to do the right thing. If there is a cost to doing the right thing, then so be it. What net metering does is put more of that cost on the companies that generate and distribute electricity, which they pass on to customers who cannot install, or afford to install, solar. This limits how effectively each installation actually improves grid stability and also limits just how much of a reduction in greenhouse gases we actually see. More than anything, net-metering contributes to the rich getting richer and the poor getting poorer...and this is coming from someone with solar AND batteries installed.
@ProjectsWithDave 2 жыл бұрын
Thanks for your thoughts. I believe net metering is the mechanism through which many people who could not afford batteries are able to start a solar system. Later, expansion into battery storage can be made. However, it is possible that future utility scale storage will be much more efficient and cost effective than individual installations making grid tied systems a more balanced solution in the future than can be achieved by a multitude of oversized and underutilized off grid systems.
@jasonbroom7147 2 жыл бұрын
@@ProjectsWithDave Where it is available, net-metering benefits those with means, at the expense of those who cannot take advantage of it. What if, instead of net-metering, all surplus power your system created went to lower the cost of electricity for those less fortunate? Could we reduce greenhouse emissions AND narrow the gap of income inequality? If that is going too far, I think the middle ground is fair to both sides. If neither the wealthy nor the poor are impacted, either way, by net-metering, I could live with that...especially since it's really supposed to be all about reversing or slowing climate change.

On average 5500klw per month and it would not make sense for the amount of panels even at 50% coverage. I would need 56x 500wat panels to cover half my monthly cost so that would not make any sense for the cost of only the panels would be 25k give or take and thats not including the rest of the build. It would take me endless years to even break even.

In my area the grid companies pay so low rates that it is not worth it to install the extra stuff to sell a little back to the grid. F.ex. they stop paying you when the 0,- level for the bill this month is reached. So, I went for Growatts in a 3-phase parallel setup and no sellback. Perfect for my use, I am mainly looking to reduce the grid cost as much as possible, aka supply my own solar/battery.

Any ideas as to what is going on would greatly help.
@ProjectsWithDave 2 жыл бұрын
Yes, I think I can help. Your solar app is measuring the output from your inverter so it captures all the production. The utility company can only measure what you back-feed to the grid. This is the "net" production (net=production-consumption). When your consumption is greater than your production the utility company sees 0kWh's of production. Then on a sunny day at noon when your AC isn't running your utility company sees an overproduction at your location feed back through the meter. Hope that helps.
@ryanmarshall4741 2 жыл бұрын
Dave made the assumption that over-production credited back at the same rate you pay. I would think this is not typical? I'm in Missouri. Credit back is at "wholesale" rate of $0.04/kwh - and that gets applied to taxes and fees. Plus, Evergy (energy company) has minimum $11 monthly active account fee. Does anyone have more like this setup or do you have more 1-to-1 net metering credit like Dave?

Dave, great video! I am also in Ohio and am planning a home solar project. May I ask if you are still able to use net metering on a monthly basis in 2024? I heard changes are coming to ohio that would limit it (similar to california). Also, do you get credit only for the "generation" fees and still get charged "transmission" fees for the nighttime energy you get back? Thanks!
@ProjectsWithDave 5 ай бұрын
Right now in Ohio it depends on your utility. Mine is still net metering by the month. My base connection fee is higher because I have solar. I get $0.06/kWh for overproduction up to a limited amount. With my latest expansions I am able to cover the connection fee with my over production most months and sometimes carry a surplus credit that can be applied to my December/January bills which I still can't cover with solar.
@doinkeroni 4 ай бұрын
@ProjectsWithDave thanks! So since you get $0.06/kwh for excess generation, does that mean that you are paying about $0.09/kwh ($0.15-$0.06) for energy you consume when the sun isn't out if you have already have a positive monthly balance with the grid provider?

Time of day is not a factor for me. Production in the month is the net result. I pay about $0.14/kWh if I use more than I produce. If I produce more than I use for the month I get $0.04/kWh but only up to 20% overproduction. That is why in my situation it does not pay to overproduce, that would make it take much longer to pay off my system.

How big would you need to overbuild your solar system to break even and not have any power bill? Earn enough net metering credits during the day to run your house and run it at night on credits from the grid. I'm trying to figure this out for a house that is about 1500 sqf in Florida. I've heard battery backup isn't capable of running AC at night along with everything else unless you had a ton of them which is expensive. I'm thinking it might be better to overbuild the amount of solar panels and use the net metering credits instead and just have a battery for emergency situations like when the grid goes down.

I am currently designing a system for a property we're buying in Missouri. The state net metering legislation from 2007 states that over production (net excess generation NEG) during a billing period (monthly) is credited to the customer's bill at a rate *at least equivalent [to] the utility's _avoided cost rate_*. Another detail is that net metering is only available until the net-metered systems equal 5% of the utility's single-hour peak load during the previous year. I can't find numbers which let me see whether the amount of connected systems are at or approaching that 5% number. The legislation doesn't clearly state what happens if that 5% is met/exceeded. Does it mean no additional net-metering connections will be allowed or does it mean all existing systems will start to get prorated? Currently, it looks like the avoided cost rate (i.e. cost of production) is around $0.04 while the average retail rate is somewhere in the $0.13 range.

@ProjectsWithDave Жыл бұрын
I suggest you ask your power company if there is any impact to the meter. In my experience if you run your system without the "net meter" installed you will only reap the benefit of the power you consume as it is being produced. For instance, if you are producing 7,000W but your house is only consuming 5,000W, then you are giving the utility 2,000W for free since the meter can only measure in one direction and you can't store the extra power. In that case, it makes sense to do all your high power activities in the middle of the day. Hope that helps.

i have been looking into solar systems and found that the added expense of net metering equipment is a factor that never gets talker about. Also i dont like the fact that if the grid goes down then my production stops(this is not the case in all areas but seems to be common) and i am without power even though i have a power plant that could be providing me power. I have decided to go with a system that uses my panels, my batteries my inverters and my outlets to provide me with power. If and when my system cannot provide power then it transfers to the grid to provide what i need. No fees for extra meters, or having solar and batteries. I have paid for my system up front and will add to it as i get the funds. I also look at my system as an investment, money in the bank gets almost zero interest. Money in my system pays me a monthly dividend that goes into an account to purchase more to add to my system.......

Sound like you have a plan. I started with a grid tie system because it is the fastest way to pay off my equipment. Now I am using the savings to pay for expansion into battery backup solutions.

Here's a suggestion Dave, why not give the most important piece of information first. Where are you located!!
@ProjectsWithDave Жыл бұрын
Ohio, but the most important piece of information is where you live. The rates and net metering rules are all dependent on your locality and utility, I use my actual situation as reference. Thanks!

@@ProjectsWithDave I think you missed the point of my comment. I know where I live but no one watching your video knows where you are. If you are going to start stating a lot of details about rules and regulations you need to give your location. The internet is a lot bigger than your state/country.

Your house is consuming a huge amount of power , I think ours uses about 10kw/hrs a day in the summer. What are you doing in there? The good thing is you're using 100% of the power you produce because of this net meter , in the UK you can't use that , no reasonable FIT (£0.05/unit) and they charge us £0.30/unit (6x as much)....crazy

Wow, that's a big disparity! You would not want to over produce, or it will take much longer to pay off the equipment.

@@ProjectsWithDave Yeah, we're looking to install a hydro system on our fish farm , it'll produce 9kw 24/7 356 but the best I've been offered by my electricity provider Scottish Power is £0.05p /kwhr and the same company will be charging me £0.32p to buy it . Something needs to change quickly in the UK , 10 years ago they were offering £0.45p for solar whether you used it or not.

Subsidies by their very nature can't last forever. It's always best when technologies can stand on their own. Assuming you have a consistent source, the nice thing about Hydro is you would have a very reliable constant output. Much easier to utilize than solar.

Ok, so dumb question. What if I just want to reduce electric usage? That is, I will never, at any time, gen more than I need. So I would never sell back to the grid. It still OFFSETs the usage, correct? If I generate 0.5 kWhr but my home consumes 3 kWhr (for that particular day), then I will only be charged for 2.5 kWhrs (for that day)?

The is that some states are looking at penalties for having solar up here in Alberta Canada we have net metering on only the energy portion so that means that to stay grid tied we still have 180$ dollars of grid and municipal fees as well as billing fees so at 40 $ per month savings by the time a system is paid for it is lucky to have paid for it self the only way is to go low budget solar ie 110 volt under a grand fortunately I found utube other wise I would have listened to the glowing reviews of preppers who only care is that it works when bought not wether it last or if it eats batteries so you're buying new ones every 12 to 14 months or if you run out of power every other day you need true net metering where if you produce more than you use they pay you money but very few places have that and the one's that did are changing soon the only way solar will be worth it is non grid tied
@ProjectsWithDave 2 жыл бұрын
Yes, if you want a system to pay itself off in a reasonable amount of time you need grid tie with net metering, and there is always a risk in the areas that have net metering that it will go away at some point. That's why I am always shooting towards the shortest payback time I can get.
@SkepticCyclist Жыл бұрын
You use a lot of electricity. We have AC and a pool, the most we ever use in the summer is about 40 kwh. Winter we use about 10-15 kwh per day. We have a 5kw system and are a net producer. We end up making about $300/yr in profit for our true up at the end of each year.

That's great! Sounds like your house is not all electric, or you live in a warmer climate. That's why it is important to know your actual consumption before installing a system.
@bateslabel Жыл бұрын
Net metering is rapidly disappearing across the country. There is a lot of focus on the net of grid tied systems, but grid tied systems are either being eliminated completely or the pay back substantially being reduced. Solar hopefully becomes more affordable so the payback is still within 6 years or so without net metering.

That's a good reason to target a short payback period.

What makes net metering a joke is by law when the power goes down your solar system goes down. So that's why I don't participate in Net Metering. I invested in enough batteries to get me through the night. They've also implemented a $25. Minimum electric bill so I am adding a couple of circuits back to the grid side of my system so I can use as close to $25 as possible. The zoning in my city says that you have to be hooked to the grid or your property is considered abandoned and uninhabitable.

Requiring grid connection would be highly frustrating.... I currently have a small battery backup system that can also be charged by a generator for emergencies. You can see the setup here: kzfaq.info/get/bejne/eOB9dLpp0L2Uc4k.html

Thank you for describing how you are a SOLAR RACKETEER! You use the services of the utility and don't pay for them. You foist power onto the utility whether the utility can use it or not ---and then compel the utility to supply you with power regardless of the cost to the utility. Your neighbors and businesses have to make up the costs you don't pay ---raising their rates. Your design your system to get the maximum personal advantage. Yet the utility isn't allowed to do the same thing --- they HAVE to take your power whether they can use it or not.

Thanks for your thoughts on the topic. Maybe your statements are accurate in some locations, however, my situation is different in the following ways: 1) I am part of an electric co-op. The policies are managed by the user/owners of the co-op. They don't have to take any power from me, the contracts for production are all individually negotiated. 2) I pay an additional fee each month to be able to feed solar power back to the grid. 3) If I overproduce, the utility only pays $0.06/kWh which is a very low rate for power. 4) My utility has regular "Peak Alert" notifications when the utility is struggling to meet the demand. During this time they use radio controlled devices to turn off water heaters. This is usually the time when I am producing the most power which would be a significant help to the supply and demand issue. 5) If there is a time when the relationship is not mutually beneficial, I'm sure the terms will change. In some places there is a surplus of solar power and the energy rates actually go negative. We don't have that situation where I live at this time at least. I hope that helps. Thanks!

If I don’t get a check from electric company every month it’s not worth going grid tide . Some electric companies just take it off the bill but you still pay a surcharge for outing electric back on Off grid is the best and make your own power company Get your neighbors to hook to you and you charge them . Lol only if it’s family I power 3 houses and 2 barns 3 sheds A pool Hot tub Well pumps Etc

Yes, in retrospect it would have made the array a little larger, but I was trying to be conservative with my initial investment.

Having the capacity to produce power, with no ability to utilize it reduces the value of the equipment. That available power is "wasted."
