Berlin-based climate research institute Mercator Research Institute on Global Commons and Climate Change (MCC) has released a new study indicating that, in the last decade, the cost of solar power has dropped by 87 percent, and the cost of battery storage by 85 percent.
Solar power and storage prices have dropped almost 90%::undefined
They are not rare. It is the fastest growing energy production mode and is growing faster every year.
Residential installations lag behind the commercial due to installation costs, but they are blowing up as well. I can walk around my neighborhood and see a couple dozen homes with it.
It’s also highly regional. The further south in the northern hemisphere the more common.
UK its partly roof size/shape limiting the amount of panels you can get in the optimum location, partly the weather, and partly install costs.
If its going to take me 8 years at least to pay back vs. not having it I am not going to bother. Some people got lucky with lifetime buy back rates for the panels to the grid so they made bank of theirs with 50p a kwh ( and electric was around 24p a kwh to buy from the grid) but those rates got cut to like 4p a kwh, when even a cheap EV tarrif is like 9p a kwh
There are some finance deals available from the likes of Eon but its hardly high end gear, which I think is needed to make the most of the UK roofs and UK sun. Time you start paying interest on it, it becomes an even worse deal.
I would save more money by just having a battery installed and charging it on my EV tarrif overnight.
Where I live, power companies successfully lobbied to charge a minimum fee to people using a grid-tied system (as opposed to off-grid). So now a bill that might have been lowered to $9.00 will cost the minimum fee of $30.00 (actual example). You might say, that $30.00 is still a very low power bill but how long will it take before that starts going up? They are also lobbying to buy power from homeowners for less than they charge homeowners. This was a huge turn-off for me considering the high cost of installation. When I asked the solar installer about off-grid installations, he said they weren’t allowed to offer those. Not sure why but got the impression it was a government thing and not a company thing. Not sure.
It’s a company thing. Government can’t force you to pay for electricity if you don’t want it.
However off grid setups are more complicated and require a different design philosophy, so most solar companies don’t do them. You have to shop for companies that specialize in off-grid setups.
Weird, here we got 11kW solar panels with inverter and 7½ kW battery for USD $12900,-. Installation (starting monday next week) is USD $ 4300,- complete with panels, wiring, inverter and battery including authorized electrician to connect it.
Meaning installation is only a fourth the total price. So clearly the panels are way more expensive, and that is in Denmark, where skilled workers are among the highest paid in Europe. AND on a ceramic tiled roof, which is the most demanding and expensive to have it installed on.
This is a completely new solar panel installation, which should begin next week. so prices are as they are now here.
PS:
For the above prices the hardware needed for installation is included with the panels.But I think that’s standard.
About a third of the houses in my neighborhood have gone solar. My household was one of the first to do it about five years ago and every time I go for a walk I notice a new one that popped up. Our solar system payment is about half what our electric bill used to be and we make more electricity than we use every month of the year, even with charging a plug-in hybrid car. Far from “no one is going to do it.” I frankly don’t understand why more people don’t do it.
21 panels and very simple layout. The longest part was building the frame to hold the panels. Installing the inverters etc. took a little time and our town is a little strict when it cones to construction. This is a very good installer which doesn’t rush things just to move on to the next job.
I looked into getting solar installed. Best I could get in my area was $45k for a 10kW system or $97k for a 20kW with 2 power walls for storage. F that, even with government subsided rates.
That’s just absurd, why is it so expensive for you? You could install it yourself for the most part, it’s not super complicated, just physically difficult. And then pay an electrician $500 to connect the inverter to your main panel.
The reason include the increased efficiency of solar panels, government incentive measures, the widespread adoption of electric vehicles, and advancements of battery technology, especially lithium-ion batteries. solar and energy storage are expected to continue becoming more affordable, contributing to efforts to address climate change.
Maybe I missed some points by skimming, but the arguments made in that article are that:
1 Australian researcher agrees with his stance
a region had 22% of its power produced by wind at one point
I guess the claim “it can be argued” is technically proven true, but the majority opinion I keep hearing from the electrical grid engineers in the news is the opposite
And, well, sometimes it just simply is night, and sometimes the wind doesn’t blow. We don’t have the battery tech to run from storage alone
But, honestly why wouldn’t we use nuclear? It’s the one power source we have without any real downsides untill ITER finally brings positive results
And, well, sometimes it just simply is night, and sometimes the wind doesn’t blow.
Do you really think this isn’t already taken into account?
We don’t have the battery tech to run from storage alone
Nobody is making that argument, as far as I’m aware. There are plenty of ways of storing energy, e.g. pumped hydro, that would work in conjunction with battery storage.
But, honestly why wouldn’t we use nuclear?
The obvious one. It’s wildly expensive when compared to renewables, and that’s before the usual nuclear build issues of cost and schedule overruns.
If you are willing to DIY you can cut that number dramatically. Out of curiosity what was the size of the array in that quote and did it include battery storage if so how much chances are that you can cut it by anywhere from 50% to 75% if you’re willing to Simply purchase directly and install yourself. The amount that installers charge is absolutely asinine usually 50% or more of that quote is just the installation which is in the same because it’s not difficult at all. People like to act scared like oh that’ll be difficult or hard or dangerous, it’s extremely simple you’re dealing with DC which is very straightforward everything is very clearly labeled on that equipment and it’s quite simple to do yourself
I can’t think of any One-Stop shop for literally everything, but there is a lot of great material out there both on forums and on YouTube. If you take it one step at a time and look at each individual piece of the installation you’ll be able to find fantastic instructions for all of them fairly easily.
If you are in the US I recommend purchasing from signature solar, they have a lot of great bundles that will both save you some money and get you everything you need. I’d also say they have the best battery storage options, their rack mount batteries and their new wall mount battery are both fantastic and very easy to work with. They also sell solar panels by the pallet which helps you get a nice large array at a good price.
If I had to pick the hardest part it would just be making sure you get the grounding right on the inverter, if you’re not careful it’s pretty easy to end up with a ground Loop which isn’t particularly dangerous but it will cause lots of weird little issues like flickering lights and other annoyances. But it’s fairly easy to correct it it’s usually just a result of people connecting both the input and the output on the inverter as well as bonding the secondary panel to the primary panel which creates a ground loop. The solution is as simple as just don’t connect to the input power ground to the inverter only connect to the output ground so that it has to go through the ground Bond on the panels
It will definitely sound like a lot, but again if you just take each individual piece by itself it’s very straightforward very simple and you’ll be able to get it done while saving an absolute asinine amount of money compared to an installer.
I will warn you that if you try to do gridtie, which is where you’re able to send excess electricity back into the grid. That comes with a lot more red tape and can get a lot more complicated. I personally did an off-grid setup, which still uses the grid as a possible input so if my batteries are dead and there’s no sun out I can still use the power like normal it’s just not capable of sending Excess power back out into the grid so there’s a whole bunch of red tape that I don’t have to worry about.
An off-grid setup with grid power option is still considered a grid tie in my area since it needs a way to prevent backfeeding to the grid. Which is totally doable in several ways, just one additional thing to be aware of.
And as a former solar installer, I also remember looking at signature solar and thinking their kits looked the best.
That doesn’t really make sense, since an off-grid inverter literally cannot backfeed. It’s essentially just a computer UPS on steroids. It accepts the grid as an input that it can pass through but it’s not possible for it to push energy back to the grid.
I mean yes if you decided to hook its output directly up to your Mains panel without separation you would be back feeding. But only for maybe a few minutes at most as you would also destroy your inverter because it has no mechanism to synchronize the output with the mains since it’s not designed to backfeed
I’m not really sure what you are talking about, you need to synchronize both the phase of the power and the frequency. If they differ even slightly you damage your equipment. This is why when running multiple inverters in parallel they require both a Communication cable and a power sharing Cable in order to ensure that they stay perfectly synchronized. Inverters capable of doing grid tie have equipment in them to monitor the mains power and make sure that they stay synchronized with it. Whereas an off-grid inverter does not contain that equipment which is why they are generally cheaper
There are several different possible phases for 120 volt they are not all the same. And while hooking to the mains may be standard practice for something that can grid tie it is not standard practice for an off-grid inverter. You are specifically expected to have a secondary panel specifically for that inverter. The mains power will reach that secondary panel through the inverter when it’s in pass through but the panel should in no way be connected to the mains directly (other than a ground bond between the secondary panel and the mains)
With that having been said, I have no doubt that solar installers have instead opted to continue to use inverters that are capable of grid tie even in a installation that will not be backfeeding. Probably just to reduce the amount of inventory required so that they can get full purchase orders. But that doesn’t change the fact that a proper true off-grid inverter is not capable of tying into the mains without destroying itself
The fact that you say you were a solar installer, but you’re not even aware of something as simple as phases and frequency synchronization is part of the reason I feel like solar installers are wildly overpaid. You’re basically doing the bare minimum without really understanding what it is you’re doing
Is that paying cash for the solar system or financing? Financing can devastate the ROI with interest rates today. I’m looking at as long as 12 year ROI with possibly as short as 7 year ROI if I consider the USA’s federal tax incentives. My slightly southern latitude (a border state with Canada) also likely contributes to slightly higher generation results using the same equipment.
How are the government incentives in Canada? I’m super envious of your great hydro power, my neighbor.
1800sq ft home, my power bill is a few hundred in the summer, I feel there just isn’t any competition here there only 2-3 companies doing it and they’re all small
It could be that those companies are evil, or perhaps their own prices are just very high because the industry isn’t scaled up in your area. Maybe they have a really hard time hiring equalities installers, and have to ship in parts from far away.
It was like that in California 20 years ago but it has changed enormously. When you drive down the street, how many houses have solar? It’s probably 3 in 10 here. I get nonstop Facebook ads and can name about 10 companies. With this comes lower prices. But there are still cheats out there. Never work with a “no money up front” company unless you only want to enjoy 10% of the benefit of the panels. For some it may be the only option but these companies are shysty as hell.
There almost 0 solar houses here, 1 in a hundred maybe. A few businesses have been doing it lately, I’ve seen 2 gas stations and several schools in the area do it. I’d like to get it done before my backwards ass state makes it illegal or something
$50k is a pretty large installation, 18kw-22kw I’d guess for solar only (no battery storage). I’m hoping thats only a max of 100% replacement of electricity sourcing (meaning essentially no net grid consumption after you’re installed). What’s the price per KWh for electricity delivered to your door in St Louis? Its gotta be pretty crazy cheap if you’re that large a consumer of electricity and you’re paying in cash with no battery, and still looking at multiple decades of ROI with the US federal tax credit.
I don’t remember the kWh specs and price off hand but a decent portion of the cost was that I’m in a 1.5 story that faces S and have a lot of small roofs rather than one large roof so it’d be a bunch of panels that didn’t have full sun most of the day. Which is true of all hundred houses in my subdivision as well. Basically build of the house made this difficult or impossible
Does that mean a substantial portion of the $50k quoted was setting up lots of panels is many small spaces, (because of the broken up nature of the roof) and that perhaps the system was oversized its electrical capacity because of the assumption that it would only be fractionally efficient because of the substandard angles and shading? I could see that. Certainly roof designs and even large mature trees can make solar unfeasible in those situations…
Maybe, I was so mad I didn’t even get more quotes, I should really do so but I was expecting 10-20 at most and hearing 50 kinda put me off the prospect for a while. Decided to spend effort on other home improvement we could see instead
In Canada you can get a 40k loan from the federal govt that is 0% interest on a 10 year term for doing green upgrades to your home. My solar generates more in credits than than the cost of the loan over the year.
The Greener Homes Program is a bit of a pain to jump through all the hoops but getting thousands off in grants and a 0% loan is worth it.

I heard the prices dropped a lot around 2012 too. Why are solar installations still rare?
They are not rare. It is the fastest growing energy production mode and is growing faster every year.

In america the installation costs as much as or more than the panels. Until the install costs come down no one is going to do it.
This is why I pay extra for my co-op to source it. Cheaper to build/maintain solar/wind farms
Keyword coop. People hate sharing here. It’s like a “socialist threat” to their autonomy.

Insurance companies have a lot of bullshit rules in certain states about the roof(Florida) which drives up the costs to install.
That sucks, seems like an opening for an Insurance company to capture some market share. Unless of course it’s all one big cartel.
About a third of the houses in my neighborhood have gone solar. My household was one of the first to do it about five years ago and every time I go for a walk I notice a new one that popped up.

Far from “no one is going to do it.” I frankly don’t understand why more people don’t do it.
Prices for the batteries and panels themselves have dropped. Just not the cost to install them.
What a shame. Is there no competition among contractors or is it inherently expensive?
It’s mostly just time consuming. It took 5 days to get the solar installed on our roof.
Seems like a huge project. Or a challenging roof layout.
21 panels and very simple layout. The longest part was building the frame to hold the panels. Installing the inverters etc. took a little time and our town is a little strict when it cones to construction. This is a very good installer which doesn’t rush things just to move on to the next job.
Ah yes. This is why batteries in Aus cost the same as they did 10 years ago. Capitalism working as intended
Batteries definitely do not cost the same.
Well that’s a compelling case you make there.
Have a counterpoint:
Solar battery average price in 2018 was $10k for 10kw Its now $12k for 10kw.
So you’re actually right! The price has increased.

If we use tax money, if it is important for entire world and survival of humans, then we wouldn’t even care or notice
I looked into getting solar installed. Best I could get in my area was $45k for a 10kW system or $97k for a 20kW with 2 power walls for storage. F that, even with government subsided rates.

Tell me again about how we need to build more nuclear.
We need nuclear because it can cover 20% for 50 years, then we are out of suitable Uranium (allegedly).
That includes an expected undiscovered amount of twice of what has already been discovered.
Clearly nuclear can’t solve the climate change problem alone.
Solar and nuclear address completely different goals.
I know. Nuclear provides base load power, which can be argued is not needed any more.

I was still quoted 40K CAD. 20 year ROI. Not feasible for me.
Well it’s the company/ies not the product
Wow. 3000 square foot home here so we had a sizable system. It was $15k USD.
Ha, mines like 1200

This is standard practice. Inverter - > monitoring - > maybe a knife disconnect - > main panel.

Bruh I got quoted 50k in St. Louis last year, would take decades for roi
That can’t be for a home. If it was it was predatory nonsense. It should be a 7 or 8 year ROI with a 20-30 year service life.
Maybe not all areas have much competition driving prices down? I’m in sunny hippie California where every other house has solar.
1800sq ft home, my power bill is a few hundred in the summer, I feel there just isn’t any competition here there only 2-3 companies doing it and they’re all small
It could be that those companies are evil, or perhaps their own prices are just very high because the industry isn’t scaled up in your area. Maybe they have a really hard time hiring equalities installers, and have to ship in parts from far away.

Was that recently or last year? Prices were out of control last year. Here prices have dropped almost 30% just since May.
July last year.
OK, you might be able to get offers at about half the price now then. If things are like they are here.
I calculated our ROI to about 9 years, the company however promises about 6, but I think that’s overly optimistic.
