Addendum to #1: Don't assume your power company will credit you back on a 1 to 1 ratio. Check first before deciding what is most cost effective for you in your area. Some electric companies will take your 1KWH that you produce during the day, and only give you a third or a quarter of it back at night.

[@keithhobbs1]

You're lucky you're not in the UK my supplier gives 3.5p per unit. Which is just under 10 percent of what they charge me on import 😕

[@Alrukitaf]

@@keithhobbs1 Better if we all go off grid, then they’ll beg for access to rooftop power. Or if groups of people band together say on each block. They can negotiate better prices collectively. Or, governments can wake up and smell the coffee, and regulate for equal price each way, just with time-dependant tariffs. So we put power into the grid at peak times, and try to use most of our car charging, washing etc at off-peak times.

[@datsuntoyy]

I pay an average of 4.1 cents per KWH and I get .8 cents per KWH. But to be honest, I used to pay 13.1 cents per KWH so it's still a plus. Last months I sold back about 230 KWH more than I bought, but with the Air conditioning starting up now, that'll change in the next few months.

I realize this is an older video, but to respond to one statement... "Why pay for batteries when the utility grid will take care of storage for you?" 1. My utility company only gives me a 30% return on the power I give them 2. Power availability when the grid goes down

Grid tied systems have the disadvantage of having no power during a power outage. Having a hybrid system is another option which has been much more affordable since this video was released. Rack mounted Lithium Iron Phosphate battery systems that store about 5000 Watt Hours (KWH) cost about $1750 which have built-in battery management systems, cell heaters, etc. With that kind of power 30 KWH costs less than $11K plus tax, shipping, and installation cost (unless it is a DYI install). A grid cutoff switch is necessary to tie the solar battery system to the grid once power returns. It is worth noting that Lithium Iron Phosphate batteries (with respect to Lithium Ion batteries) are much more durable and have a much longer lifespan (at least 10 years) and can last a lot longer. Because of their weight increased weight, these batteries are ideal for stationary use and are much less suitable for non-stationary use. As the name implies, manufacturers market server type racks that include bus bars for vertical mounting for multiple battery systems. Following a nature or man-made disaster (excluding an EMP attack or a mass solar ejection which would fry nearly all electronics to the grid), a hybrid system would supply endless electrify to a home unlike a Generac generator which requires it to be supplied with fuel and when that fuel runs out. By the way, the total cost can be around $12,000 to $15,000 to buy and install a whole-house which is somewhat less than the cost of a battery backup system.

[@springerworks002]

Just add a shutoff on the grid side.

Don't forget the battery will be shot in 10 years. A gas-powered generator beats it hands down - it's 10x cheaper and maybe I'll have to replace a couple of gaskets once in 20 years... Yours is the solar mistake #9.

[@datsuntoyy]

#1) Because in some areas you are only credited a fraction of you sell vs what you buy. It's also insurance against the grid being down. For those in unreliable power areas like CA and like to keep the cold stuff in the fridge cold, a battery system is worth it.

[@rjvanloon4769]

Exactly. The whole point at first for me was to have a backup for when the grit goes down and not have to worry about storing huge amounts of gas for the generators. So grit-tied does no good for that.

[@jernplays1815]

Yep this video is misleading at that. If you got the pannels have the batteries 🔋 flip a switch and go off grid if your grid is no longer up.

@@rjvanloon4769 I guess it depends on how much it stores doesn't it? The battery power may only last one night, right? What if like in TX the power outage was for a week or more and in winter no less?

[@WreckDiver99]

Yep, and if you're in a rural area, where you might be a very low priority line repair, you'll want a secondary power system, be it batteries, or a generator. No matter what, you'll need some form of BMS if you use batteries, and it may actually be worth staying away from the "used Tesla Cells". Some have an AMAZING luck, but I've heard of people buying a battery system, tying it in, and finding in 6 months that half the cells can't hold a charge at all... I'll have a grid tie system, but I'll also have a battery solution. Still in my very early planing stages, especially considering I'm not sure if we're building on our property or somewhere else. I want the property, SWMBO want's local. :(

[@datsuntoyy]

@@WreckDiver99 It always made me wonder, if you have a pack with say 100 cells and 10 have "worn out", wouldn't it stand to reason the remaing 90 are probably very close to being worn out also? we went with a 6.6kw on-grid no battery system.

with a centralized invertor...the entire panel array only produces at the rate of the panel with the lowest out put...so if one panel is in shade due to sun, or dirt, or debris, or any reason, then WHOLE system is truncated. Also...DC loses power over distance, so the invertor has to be near the solar panels... with sunpower and each panel with an invertor...you can put the panels anywhere you want, and if one panel gets shaded due to cloud cover, then only that panel has reduced output.

[@hotdognl70]

We have our system over a year now and the payback time was estimated at 6 years. With the current rise in energy costs in Europe the payback time is reduced to 4 years! Our energy provider allows a 1 to 1 deduction (our cunsumption is negative) and the buy back rate of the surplus is only 40% but it is absolutely a good investment. We over invested in 50% more pannels against the advice of the bare minimum (the additional cost were only 15%) to be ready for the heathpump wich was installed recemtly.

Here in the UK, new installs get very little credit for power fed back to the grid, approx one sixth of what you pay for import, so a battery is a very efficient idea.Also we can import power during restricted overnight hours at approx one quarter of the day rate, and can charge the battery at cheap night rate, and use it during expensive day rate. At todays rates and looking to the future, a battery is a really good idea, possibly good just to install without solar and enjoy the cheap night rate.

My brother did Grid tie solar, over 10 kilowatts, and when the power went down in Texas in the coldest winter time he had NO ELECTRICITY!! He had no batteries, no storage and no means of using kilowatts of to light or heat the house. Solar panels can be added on later if your inverter and charger can handle the extra power so going large on the hardware is a good idea. The same is true of batteries, they only store the charge they don't force too much current on your system when wired in parallel, unlike wiring in series where the voltage goes up and can adversely effect everything.. Also to consider is having a separate system for certain applications like AC cooling or charging a car, kept wired separately from your breaker box set up. Lastly some inverters can be combined or stacked with others to increase their output.

I live in Florida and signed on to have a new roof and a solar system. What allot of people don’t realize is that your utility bill includes other charges other than electricity. Don’t let a salesman tell you that a solar system will wipe out your utility bill cause it won’t. My utility bill last month was $201 and included electricity, water, sewer, gas, garbage, storm water and fire department. Of my $201 utility bill $64 charge was for my electricity usage. So if I had my solar system up and running last month my utility bill would have been $140 and not $201. I still have to pay for everything else each month besides electricity. To me it’s still worth doing as my house is 18 years old and the shingles are beginning to fail and I’m developing leaks in the ceiling. I went with a solar company called Meraki which included a new roof with a 50 year warranty and a new solar system with no money down. I live in Florida and my electricity usage goes up in the spring and summer with the air conditioning. With electricity being the largest part of my monthly bill it will help me offset my electricity charge.

Grid tied isn't necessarily cheaper, it depends on where you live (regional or country). For example it is great if the regulation allows you to get the same amount of electricity back for free as you put in, however in that case you are using the grid as a battery, which makes it actually more difficult for grid operators to manage the system. This is why such schemes are slowly dissapearing everywhere and you will still have to pay something for using electricity your panels provided to the grid. For example if the grid operators only pay you the generation costs (ie. don't charge generation costs on equivalent amount of electricity your panels put on the grid), this might only reduce that part of your bill by around 25-35%, instead of 100%, since things like grid costs, distribution and taxes might still be incurred. If this is the case an off-grid/far hybrid system might be more interesting on the long term even pricewise.

You're right, except for one little thing. Local electricity generation does not burden the distribution network. Distributors like to promote virtual batteries because it brings them carefree profits. I'll explain. Each village has its own transformer and believe that no energy produced from the panels will get out through this transformer (it can get if there is no consumption). For example, there are 50 houses in that village, of which 5 houses have an On Grid (battery-free system). The distributor will calculate the purchase price of energy in kWh, which is only a small fraction. This calculation is based on those 45 houses that consume your panel energy at a lousy purchase price, but the distributor sells it to 45 houses at full price. In addition, you pay for electricity meter rental, power distribution and virtual battery. The distributor in the locality collects more money than in the normal state without panels. The distributor keeps this condition with a good tariff, which will offer you and you will save a little money, which is not a significant saving. If the panels buy another 20 houses (50-5-20 = 25), 25 houses are no longer financially interesting for the distributor and they come up with a fairy tale that it would overload the network and not connect these houses to the distribution network. However, network congestion exists, but from large solar power plants in front of the village transformer. This is true of so-called network congestion. But otherwise I agree with the others. It is better to stay in the network and get a large UPS with batteries (hybrid) for the panels. Batteries can be lead traction, which are cheap and safe. Their capacity is not high, but they have a greater depth of discharge than car batteries. If the power supply is interrupted or you switch off the distributor circuit breaker yourself, the solar UPS switches to battery operation. Every kWh that does not have to be paid to the distributor is a saving.

@@DL-kc8fc The problem with your local argument is that this only applies if a few have solar panels, if most houses in that local area have solar panels, they'll all produce power at the same moment and likely will have to offload this to outside the local zone (ie. industry). Local grids with lots of solar are only less difficult to operate if you have some battery back up to store some of the charge.

@@MDP1702 But I write about it all the time. I'm not talking about an open distribution network vs. industry, etc., but about the network behind the transformer in a small locality, such as a village. If the location behind the transformer is saturated with photovoltaics, it is not financially advantageous for the distributor and he does not want to connect most houses with new photovoltaics "on grid". Therefore, I write clearly and unequivocally that in that case it is good to install a hybrid (photovoltaics with batteries, ie a backup method of UPS). The distributor himself will offer this solution because he will keep your dependency. The island system is really for the minority community, which will never endanger the distributor. The distributor regulates the "on grid" by offering you an unfavorable purchase price of your energy. If the distributor registers energy production in the local network, he will fine you for illegal electricity production. Why? Because the main main electricity meter at the transformer brakes and the distributor loses the profit in the locality. Yes, it can happen that at the time of minimal energy consumption, the sun shines very well and energy is overproduced. The local network does not take anything from the main network and therefore the power engineers talk about network congestion. It's such a technical terminus. The actual network congestion tends to apply to consumption for which the network was not designed, but the power engineers have come up with a fairy tale that suits them. In fact, consumption is not implemented and this creates "surpluses" in the main network, into which the constant power from hard sources "flows". This power must then be "burned" somewhere, because it cannot be regulated throughout the state. In order to avoid disproportions and damage to transformer stations, energy will be provided to another country, even free of charge. Likewise, farmers prefer to destroy their overproductive crops so that they do not have to compromise on the stock exchange. Never believe that a distributor wants to lose market dominance. Paradoxically, ordinary people's photovoltaics help him increase profits.

Where can i purchase the material ?

1:12 "So why pay for batteries when the utility grid will take care of storage for you?" You should have answered that question. 1. medical equipment 2. storm outages 3. net metering 4. minimize grid dependency. Which you answer at 3:44.

because the power company will charge primium rates for what you give them and give you a %5 discount on what you use . So you make $100 a month in power that they use.....then you use $105 a month you think your bill is $5 a month right? your bill....$103 a month!

@@crazypjk My montly bill went down to €5,- and the annual refund is ~€800. System will pay for itself in less than 6 years, not to mention the free electricity. This will change since we recently got a heatpump installed. The reason NOT to invest in a battery system is that I need 20 Tesla walls to cover the period November-January.

Nice!

I just bought a house that has solar panels on the roof. The system is in good working order and is still under warranty but I need a new roof and I'd like to sell the system to someone who is interested. How do I get started in this process? Thank you!
