I'm in south central Florida and have had a grid tie PV system (without storage) since 2015. You mentioned a minimum monthly bill and that's what I have here with FP&L. The amount recently increased from about $8/month to more than $25/month. I recently tried to add Tesla Powerwalls through Tesla website, but was told I was outside their service area. Thanks for the very informative video.

What does a solar customer do with excess power if he does not send it to the grid?

If you can't use it and can't store it, my guess is the Powerwall is going to raise your house frequency until the solar turns off like it does when you're running off grid. I demo that in this video: kzitem.info/news/bejne/rKJ_3oN9e6iHdpw

It's just kind of how this stuff works. It's exactly what the utilities are doing right now when they curtail solar and wind. You could mine crypto I guess, run a hot water heater, get another battery, charge a car, run an air conditioner, bake some cookies, whatever makes sense for your situation.

I don't see that Tesla is saying that the PowerWall won't export energy to the grid. I suspect that Tesla will batch many houses and provide utilities a virtual power plant. That way, the utility can avoid new power plants knowing that many PowerWalls will fill the need.

The problem with Tesla solar to include the Powerwall is that someone like me, who's had solar for a decade and wanted a Powerwall to add to my system, now can't get one unless I replace all my panels with new ones from Tesla. And not letting us back feed into the grid, which gives us a credit to our electric bill, now makes buying Tesla solar even more of a bad thing.

I agree not being able to export to the grid is not ideal based on the current system, but did you make it to 10:51 where I talk about the changes that are coming? Once the time of use hours and minimum monthly bills hit, I think not exporting will be our best play as solar owners.

Couple other options: 1. Solar customers get kWh credits not cash; 1 kWh to the grid=1 kWh to your house. If you don’t use all your credits, oh well. 2. Go to a constant rate regardless of time of day. Adjust that to accommodate costs of production. Are there reasons those wouldn’t work?

That's essentially how NEM1 worked in CA, but it doesn't solve the fundamental issue of having so much solar during the day and nowhere for it to go and then needing that energy in the evening.

Deep dive tutorial needed for PW+. Details of changes in PW to PW+ w/integrated inverter/gateway almost nonexistent. Can U do this?
@EveryAmp
3 жыл бұрын
From what I understand, the only difference between PW and PW+ is an increase in the maximum power output. Where PW was limited to 5kW (20A) continuous, PW+ can ourput 7.6kW (32A) on grid and 9.6kW (40A) off grid. That means customers can run larger loads like air conditioners on fewer Powerwalls. Of course, the capacity of the PW+ is the same 13.5kWh as PW, so at these higher loads it will empty faster.

Great video, that was educational at the same time entertaining. Right now, I'm torn between a 13kw Tesla panel system with 2 Powerwall vs Enphase system with 20.16kWh Encharge. Tesla is about $.56 per watt less than Enphase but I have some concern in regards to Tesla's customer service when something needs repair or service. How has been your experience with the Tesla system?

@BMW R1200GS Adventure Thanks for the reply. I just canceled my Tesla Solar due to the bundle issue. It makes more sense for where I live to install the solar panels first and add the storage later if necessary, I rarely have outages. I believe in a few years, there will be a lot more efficient battery options to choose from for a lesser price than today's market and still take advantage of the tax credit.

I think bundling up is a bad move by Tesla. It doesn't make sense for me to bundle it up with solar for my home and my location. I'm in the process of getting solar panels only and lock in NEM 2.0 for the next 20 years. I think tax credit will continue to get extended, and I can install the battery when I feel it's necessary. I rarely have outages, and for sure, the battery will only get more efficient and cheaper in the coming years. Also, the Tesla rep confirmed a Powerwall 3 will be launching very soon, so it makes no sense for me to get the bundle-only option as of now. And I wouldn't be surprised if Tesla moves to sell the PW3 by itself; otherwise, they will fall behind the market share.

It's a tricky time right now. Yes, we'll be grandfathered under NEM2, but that doesn't prevent them from changing our time-of-use hours or imposing minimum bills on us. I'm under the EV-A plan currently which has now been replaced by EV-2A (which is wayyy less beneficial for solar customers since the hours shifted so much) and I'm only grandfathered into the rate plan for 5 years. After that, I expect I'll rely heavily on the Powerwall.

Great explanation. I live in Belgium and we will get billed starting in 2022 on a capacity base, this mainly to protect the grid. We only get paid 4 cents for delivering solar at the grid. So we use as much as we can during the day time and fill our batteries at earliest possible. Rest goed to my Tesla at first and then only to the grid. Untill last year our meter was turning back but the government changed it a couple of months ago since we get digital metering getting installed.

This sounds like a problem with infrastructure, which as a consumer, should not be my problem. If PG&E makes half a billion dollars every year in profit, they can afford their own battery storage solutions for the excess generated. The only reason we're asked to shoulder this cost is because there's an energy monopoly in this state.
@EveryAmp

You're missing the part where the cost of electricity IS the cost of infrastructure + energy + people. It's no different from any other product, it just seems different because we pay by the kWh for some invisible magic product. CA tried deregulating the grid, but greedy companies like Enron proved that's a risky way to go with critical infrastructure like electricity.

Very Interesting video. While the producers and consumers have to balance, since the local electric (in my case PGE) can easily lower their own local production when I produce excess and feed into PG&E's grid. Agree it costs PGE more to manage this and I don't have a problem if they give me the wholesale rate at NetMetering anniversary - I think that is fair. I don't think the government should force utilities to pay the retail rate. Wholesale rate is fair. You make a good point about minimum fees. I have no problems paying $25 min to PGE for pushing and pulling from their grid (even if I have a battery) I have tesla solar without the battery thinking that if there is a power out I can use my solar during the day. Turns out I cannot. Is it possible to have add something to my system so that I can use my solar in case of power out withOUT the battery? Also say I add a battery (Telsa wont sell me one right now as they are reserving it for new solar+battery customers). Then *during a power out*, will I be able to use my solar directly or does it first have to go to the battery. For example a single battery will not support a 240V (like my AC) but I suspect my solar can.

I've seen off-grid capable inverters that are able to power a circuit or two from solar alone, but it's a pretty rare feature in the solar world. The reality is that you may be able to run a few things, but as soon as someone turns on one too many lights or a cloud passes by and the demand exceeds the supply the whole thing shuts down. It just doesn't really work well without a battery to buffer. When you're running off grid with solar and a battery, it's no so much that this energy goes here or there exactly, but that there's energy entering and leaving the breaker panel and the gateway balances everything by controlling the Powerwall. So, you'll have whatever loads going out to the house and whatever solar is coming into the panel. If there's not enough solar to power the loads, the gateway will tell the Powerwall to supply whatever additional power is needed. If there's excess solar, the gateway will tell the Powerwall to charge until it is full. Once the Powerwall is full, the gateway will start cycling the solar off to let the Powerwall drain down for a while, then cycle it back on to recharge. A single Powerwall 2 can supply 240V at 20A (5kW). That's not enough to run an AC or charge your car at the full rate, but it can cover most other common household loads. The newer Powerwall 2+ bumped that output up 240V at 29A (7kW), so you may be able to run an AC off of it, depending on your system, but it's still the same 13.5kWh capacity so you may not be able to run it for very long.
