I got solar this year and am selling. The cost has directly increased the value of my home.
Comment on How I Installed DIY Solar Power and Started Running My House on Batteries
Canconda@lemmy.ca 8 hours ago
Some thoughts from a solar fan boy who knows more about finance than electronics.
-
The average time to pay off solar panels (7-12 years) is still longer than the average time most first time home owners (at least before 2015). So it’s still not as viable an option for a lot of people for people who plan on selling within 10 years.
-
There is less home ownership overall. More of us are renting and there is no incentive for these installs.
-
If these systems could be reasonably relocated and reinstalled, that would probably shift the financial equation drastically.
-
How close are we to solar breakthroughs in materials/production that might incentivize waiting?

I dont know. Im up money monthly and my realtor said it adds more than it costs.

Balcony Solar Systems are the answer. You can literally plug it into your power plug. And unplug if you move somewhere. ROI is around 5 years. You can even use it for your camper if you buy a inverter-battery-combined system.
Drawback: It is reduced in Wattage (around 2kwp) and will reduce your bill just slightly. (Mine around 30€ each month). You likely won‘t install the panels on your roof and need a different place for it.

I have solar already and can’t wait to buy some balcony solar panels
I’ve got a gazebo that’d be perfect to mount them on, and since my system has a house-backup battery I think it’d be a massive benefit for me (for the price)
My whole system is 3.2 kWh so a 1.2 kWh system would be a huge boost on the cheap
I think I could get at least 800w out of it with positioning so I could basically use my AC for a lot longer
DrunkenPirate@feddit.org 4 hours ago
I recommend to buy a inverter-battery-combination which I have. It stores all the generated power (up to 4 panels possible with 2,4kwp max at all) while you can infuse 800 watt only maximum (Germany). The reduction is a safety for the power wires.
In my setup, I harvest 1,8kwh in my battery until afternoon while constantly providing 150w into my house grid. This often reaches until 4am morning. My base consumption with electronics standby is around 220w even in the deepest night. So, I don’t deliver the peaks but a steady base stream.
BlueOysterCultist@lemmy.zip 4 hours ago
I think it’d be redundant to get another battery when my whole house is already on a battery
I’d love more storage capacity (only at ~9.5 kWh currently) but I don’t think it’s worth getting additional capacity unless the price is reallllllly good

So the challenge with those is that they’re not legal in many places. In Canada our electric code requires everything be connected to the breaker box so that electricians can work safely knowing there is no current in the building.
Strata’s also often require panels on railings be mounted flush, facing sideways instead of angled upwards.
On that note, given where most balcony solar would be installed; changing bylaws to allow balcony shades and air drying launder would arguably reduce our energy costs significantly more than what energy solar panels on railings could harvest.
DrunkenPirate@feddit.org 4 hours ago
I don’t know your local laws and current setup, but Balcony Solar typically aren‘t standalone setups.
That means they need the frequency signal of your power current - 50hz in Germany. Without this they do not work. This is a safety measure to protect electricians while working.
So called Island Systems work without the frequency signal only. They provide power even in a black out situation. Balcony Solar does not in gerneral.

That’s indeed a good point, which is why we should keep the pressure on it. We can already see some campaigns forming around its legalization in some states, as seen here
There are some great resources there, so I’ll just copy some relevant information in case someone is interested:
So why can’t you buy one in Canada?
It isn’t dangerous and it isn’t banned. There just isn’t a Canadian rulebook for it yet. Canada’s own safety body has said these little plug-in systems fall outside its current rules, and the good news is that rulebook is finally being written. In January 2026 the country’s standards council started the process of adopting a national plug-in-solar safety standard
Here’s how we change it.
Canada needs two simple things. A safety stamp that says these systems are good to go, ideally a Canadian one rather than a borrowed one. And a plain rule that lets people plug a certified one in without a permit or a pile of utility paperwork. Both are already moving. Germany has plugged in more than a million of them, and Utah made it legal on a vote with nobody against. What gets it over the line here is enough of us asking.
It’s safe, it’s proven, and it works everywhere it’s allowed.
Canconda@lemmy.ca 6 hours ago
The part your missing is why it’s illegal. Canadian electric code requires everything to go through the breaker box so that electricians can know there is no current in the building.
So even if the rules are changed this introduces installation costs that could be prohibitive.
A safety stamp that says these systems are good to go
Of which there are current zero devices registered for legal sale in Canada, because of the code issues prescribed above.
It’s safe, it’s proven, and it works everywhere it’s allowed.
The problem is that plug in balcony solar is not considered safe according to our electrical code.

I know more about electronics than finance.
What I would do is take a more holistic approach to your home’s power system, with solar panels as one very useful tool in a well-stocked tool belt, that also includes:
- A time-of-use power plan from your energy company.
- A whole house battery
- A smart or programmable thermostat
- A few outlet timers
- An electric car charger with timer or some similar solution
I am currently on a standard rate power plan, I pay 14 cents a kilowatt-hour no matter the time of day. My power company offers a time-of-use plan that varies between 29 , 11 and 7 cents per kilowatt hour depending on the time of day. The game becomes, buy as little power as possible during the 3 hours it’s 29 cents, and as much as possible during the 5 hours while it’s 7 cents.
This might mean doing laundry and dishes at 1 in the morning, setting a timer to charge your EV at 1 in the morning, setting a thermostat to turn air conditioning off between the hours of 6 and 9, that sort of stuff. A battery system can store energy when it’s cheap for later use when it’s expensive. Solar power is then a further reduction in the amount of power you buy; in my area depending on time of year the solar producing parts of the day are either in mid- or discount-price times, so the bulk of your savings are coming from discounts and time shifting. They’d likely be more valuable during extended power failures than day to day power savings, as you’re unlikely to generate a dollar per day.
povoq@slrpnk.net@slrpnk.net 8 hours ago To answer these:
-
Increase in house value due to solar system is likely making this moot.
-
Small “balcony solar” system work fine for renters.
-
See 2. and for larger systems 1.
-
Very unlikely to see a major market unheaval in the next 10 years that would make things cheaper. The real price improvement happend in the last 10 years, and the price difference between LiFePO4 batteries and Sodium-Ion ones will not be large enough for it to matter in small systems.

don’t buy this bullshit. has no effect on value, and likely has a negative impact as many DIY systems are hacks.
- povoq@slrpnk.net@slrpnk.net 2 hours ago
Today a DIY system usually means a fully integrated system from a single Chinese supplier: hybrid inverter, BMS and batteries together. That is no hack, and no major difference (other than price) from what a professional company installs.
Having such a system absolutely raises the price of the house sold. Maybe not a full cost recovery, but enough to not make it a total loss if you end up selling before the usual return of investment period.
SteveKLord@slrpnk.net 3 hours ago Appreciate your passion and input but try to remain as constructive and kind as possible as calling another person’s informed opinions “bullshit” may not be appreciated. Thanks.

#1 absolutely is not accurate. My last house had a $40k solar system installed and it maybe raised my home value by $10k per my appraiser. I still thought it was fine because I had intended to live there forever. I ended up moving four years later :(
- povoq@slrpnk.net@slrpnk.net 2 hours ago
Sounds like you paid 40k for a system that’s worth around 10k. That absolutely happens with some companies that do the full installation, but it is a total rip off.

Respectfully, you are trying to generalize real estate based on your local market. That simply doesn’t work. See my other comment on balcony solar for a clear example. Your 4th point is pure speculation with no argument backing it.
I’m not saying solar isn’t viable. Just using my experience in mortgage financing to add more context to the conversation.
SaveTheTuaHawk@lemmy.ca 4 hours ago
In Canada our electric code requires everything be connected to the breaker box so that electricians can work safely knowing there is no current in the building.
if a panel is plugged into the existing house circuits, shutting off the main breaker will shut off the current.
- povoq@slrpnk.net@slrpnk.net 7 hours ago
Sure, if balcony solar isn’t legal in your place, that is an issue, but more and more places make it legal recently.
As for the realestate market, sure there are conservative realtors that currently undervalue solar systems, but people aren’t stupid. If it makes economic sense to have them in the first place, then most buyers will also make the same calculation and be willing to pay extra, because in the end they will save money compared to a house without solar.
Canconda@lemmy.ca 7 hours ago
Legalizing it would mean aligning it with the electrical code and running it through the breaker box which introduces prohibitive installation costs. It’s a safety issue, not just politics.
conservative realtors
Again respectfully, you are applying reasoning to real estate that simply does play out that way. Look up the first 3 rules of real estate. There is no substance for me to refute what you are saying because it is fundamentally anecdotal conjecture.
people aren’t stupid. If it makes economic sense
I gotta walk away from this convo bro. The biggest flaw with economic theory in general is that it assumes people make rational decisions.
in the end they will save money compared to a house without solar.
I’m not saying they won’t. I’m saying that the context where that happens doesn’t align with many peoples financial objectives and local real estate markets.

Regarding 1, perhaps you are the one trying to generalize your local market to everywhere else?
See:
Arizona, USA:
Soak up the sun: Impact of solar energy systems on residential home values in ArizonaIn particular, properties with electricity-generating solar panels enjoy an average premium of approximately $45,000 (15% of medium home value) and transaction price premium of $28,000 (17% of medium home sales price).
California, Connecticut, Massachusetts, and Oregon - USA:
Solar at High Noon: Solar Home Premiums in a Rapidly Maturing Market:We find clear evidence that solar systems are correlated with higher selling prices if those systems are owned by the homeowner (HO). Alternatively, we find no value or slightly lower values associated with non-owned panels
Southport, Australia:
House price premium associated with residential solar photovoltaics and the effect from feed-in tariffs: A case study of Southport in Queensland, AustraliaUsing the hedonic approach, the study found that the gross premium was 4.3% of the average house price; the average net premium (exclusive of the PV installation cost) was 21,403 AUD when the FiT was at 44 cents/kWh; when the FiT dropped to 8 cents/kWh, the gross premium fell to 2.4%, and the average net premium dropped to 5600 AUD. The study shows that a solar PV house does enjoy a premium in terms of property value and indicates that a higher solar rebate and subsidy leads to a higher premium
If energy efficiency increases by 100 kWh/m2a, prices increase by 6.9% on average […] there is evidence that about 98% of future energy cost savings are already reflected in a higher housing value under myopic expectations regarding future energy prices.
Italy:
The Market Price Premium for Residential PV PlantsOur results show that individuals are willing to pay an additional price for a solar home, and the average market price premium is equal to 2.69% for monocrystalline PV plants and equal to 3.08% for polycrystalline PV plants respectively.
UK:
Returns to solar panels in the housing market: A meta learner approachOur results point to a selling price premium above 6% (range between 6.1% to 7.1% depending on the meta-learner) associated with solar panels. Considering that the average selling price is £230,536 in our sample, this corresponds to an additional £14,062 to £16,368 selling price premium for houses with solar panels.

So to do an accurate property value assesment (what you’re doing) you’d need to provide at least 5 examples from each of those regions, only including comparable properties.
I’m not saying solar doesn’t improve property value.
I’m saying you cannot take one example and apply it to an entire market. Which you just did x6.

Some people would pay slightly more for a house that already has solar installed, even if it’s a 5-7 year old system. So install it, then use it as a selling point down the track.
-
Anecdotally, I’ve rented a house before that had solar installed. It was a factor in my choosing to rent that place. I don’t know how it is elsewhere in the world, but it’s pretty common in Australia to have to pay for your own electricity usage when renting a place. The solar panels lowered my bills considerably.
-
Pad mount / ground mount systems are a thing, if you have enough space. That said, anything that can be installed, can be removed. Cost is a factor, though.

I don’t see any breakthroughs coming any time soon. Gradual improvements through economies of scale will likely be it, along with any government incentives.

Re 1: Doesn’t the solar add value to the home though? That makes it viable even if selling as you can sell for more.
Re 2: The incentive is potentially on the landlord in these cases, to rent out a solar powered home for more. 35% of Australian homes have rooftop solar, many of those are rentals, because people will pay $10 more rent knowing they will save $20 on their bills.
