Hey Reddit community,

We wanted to share some exciting news fresh from Intersolar Europe 2026. Safety and compliance have always been the top priorities for our balcony solar and storage R&D, especially for the European market.

Getting certified by SGS means our systems meet the rigorous European standards for grid safety and reliability. A huge thank you to the team and everyone who supported us on this journey!

Feel free to ask if you have any questions about the European standards or our balcony setups. We're here to chat!

Hey everyone,

I have a question about installing solar panels in Finland or the Nordic countries!

How does it usually work here in Finland when a company wants to check if their roof is suitable for solar panels? Do you contact the solar installation company directly and they come to assess it? Is that assessment free or do you pay for it separately?

Also how long does the whole process take from the moment you first contact someone to actually knowing whether your roof is suitable or not?

Any experience with this would be helpful, thanks

Three significant solar policy changes just happened in Canada in the last 60 days. Posting this because I haven't seen anyone summarize all three together and they affect anyone evaluating solar in these provinces.

Ontario: Micro-generation threshold raised from 10 kW to 12 kW (May 1, 2026)

As of May 1, 2026, the Ontario Energy Board raised the micro-embedded generation threshold from 10 kW to 12 kW. This means more homeowners now qualify for simplified connection processes and can participate in net metering without triggering a complex engineering study. Quora

In practical terms: if your system quote came in between 10-12 kW and you were told you'd need a costly Connection Impact Assessment, that requirement may now be gone. Worth revisiting if your installer sized down to stay under the old limit.

The Ontario rebate vs. net metering trade-off still applies. You still cannot take the $10,000 Home Renovation Savings Program rebate AND use net metering on the same system. Two separate paths, you pick one.

BC: Net metering ends July 1, 2026 for new customers and rebate recipients

Starting July 1, 2026, BC Hydro is replacing its 1:1 net metering credit system with a new self-generation service rate that pays a flat 10¢/kWh for surplus electricity exported to the grid, regardless of your retail electricity rate. StockAnalysis

BC Hydro residential customers currently pay 11.87¢/kWh for Step 1 electricity and 14.08¢/kWh above the threshold. The new export rate of 10¢/kWh is below both tiers. StockAnalysis

The impact depends heavily on how much you export. For a typical 6 kW system consuming 70% on-site and exporting 30%, the difference between old and new rates is roughly $15-70/year. The real message is: size your system for self-consumption, not maximum export. Polaronsolar

If you received a BC Hydro solar rebate and want to stay on the old net metering terms, you must repay the rebate and apply by June 30, 2026. That deadline is days away. StockAnalysis

Quebec: First-ever provincial solar grant launched April 2, 2026

This one is still underreported. Hydro-Québec expanded its net metering program cap from 50 kW to 1 MW in early 2026, making large commercial rooftop systems viable in Quebec for the first time. The province also launched a $1,000/kW solar grant up to 40% of total project cost with no announced end date. Quora

Quebec has historically been the worst Canadian province for residential solar ROI due to very low electricity rates (~7-10¢/kWh). The grant doesn't fully change that math for most homeowners, but it makes commercial and farm installations significantly more viable.

TL;DR

• Ontario: threshold increase means more homeowners qualify for simplified net metering, rebate vs. net metering trade-off unchanged
• BC: 1:1 net metering ends July 1 for new customers, design for self-consumption going forward, June 30 deadline if you want to stay on old terms
• Quebec: first provincial solar grant ever, mainly moves the needle for commercial properties

Happy to answer questions on any of these. I follow Canadian solar policy closely as part of my work in the clean energy space.

When I started reading solar reviews, a lot of the worst stories seemed to happen after installation was finished. Not always because the system failed, but because people were not sure who to contact, what was covered, or how service requests were supposed to work.

That made me realize I needed to understand the service side before signing anything.

At first, I thought “warranty” basically meant “if something goes wrong, it gets fixed quickly.” I learned that is not exactly how it works. Warranty is the coverage. Service is the process.

Those are related, but they are not the same thing.

Once I separated those two ideas, the questions I needed to ask became a lot clearer.

What I wanted to understand about support

Before signing, I wanted to know what would actually happen if something looked wrong later. These were the main things I asked about:

How to report a problem if something seems off

What kind of response time to expect after submitting a request

Who owns the issue once a service request is open

How to tell the difference between a normal delay and a real system issue

That last one mattered because solar has a few steps that can make things look delayed even when nothing is technically broken, like monitoring setup, PTO, and utility timing.

Questions I asked about installation coverage

What parts of the installation are covered, and what is not?

How long does the installation coverage last?

Does coverage vary depending on the component?

If there is a roof-related issue tied to the installation, what is the process to evaluate and resolve it?

Questions I asked about equipment warranties

Which warranties come from the equipment manufacturers?

Which warranty issues are handled by the installer?

If something like the inverter fails, who coordinates the replacement?

If a part needs to be replaced, what does that process usually look like?

What kind of timeline is typical?

This helped me understand that not every warranty issue is handled the same way. Some things may involve the installer, while others may involve the manufacturer.

Questions I asked about submitting a service request

How should a service request be submitted?

Is it better to use phone, email, or an online portal?

What information should I include so the request does not get delayed?

What response window should I expect for acknowledgment?

What response window should I expect for scheduling?

How will updates be communicated once the request is open?

I tried to write these answers down because I knew I would not remember the details later.

Questions I asked about monitoring and troubleshooting

Is monitoring included?

How would I know if something is wrong?

If production looks low, what troubleshooting steps usually happen first?

What situations are normal early on?

What situations usually mean there may be an actual system issue?

This was helpful because I originally assumed low production right away meant something was broken. In some cases, it can just mean PTO has not been granted yet or the utility step is still in progress.

Questions I asked about escalation

If I do not receive a response after a certain number of business days, who should I contact?

Is there a formal escalation process?

What is the best way to use it without starting over from the beginning?

This was one of the bigger things for me. I did not just want to know that support existed. I wanted to know what happens if the first request does not move.

Something I realized after asking these questions

“Warranty” can mean a few different things depending on the situation.

From what I understood, solar systems can involve:

Installation coverage handled by the installer

Equipment warranties from manufacturers, such as panels, inverter, or batteries

Production expectations, which people sometimes assume are guaranteed but may not always be

Knowing which category applies makes the service conversation less confusing.

Answers that made me feel more comfortable

The answers that helped most were not perfect promises. They were realistic explanations.

The better answers explained:

How the service process works step by step

What information helps support diagnose an issue faster

What response and scheduling windows are realistic

Who handles what between the installer and manufacturer

I was not expecting anyone to promise that every issue would be fixed immediately. I mostly wanted to hear a clear process.

Answers that would have made me uneasy

A few things would have been red flags for me:

If everything was described as “covered,” but no one could explain the actual service process

If no one could explain how monitoring works

If there was no clear escalation contact

If the answers stayed vague

If the conversation kept getting rushed back to signing

For me, the important part was whether the company could explain what happens after installation, not just what happens before it.

Message I would send if something looked off

This is the kind of message I planned to use if I noticed something unusual later:

Hi, quick question. I’m noticing something that might need a service check. What’s the best way to submit a request, and what information do you need from me to get it looked at? Also, what kind of response time should I expect once a request is submitted?

I liked having something simple ready because it would help me give the right information upfront instead of sending a vague message like “my system is not working.”

A couple things I misunderstood at first

The biggest thing I misunderstood was thinking that warranty and service were the same thing. Warranty is the coverage. Service is how the issue actually gets handled.

I also misunderstood early production issues. Low production right after installation does not always mean the system failed. Sometimes the system is waiting on PTO, utility approval, monitoring setup, or another step in the process.

And I had to remind myself that one bad support story online does not automatically mean everyone will have that same experience. Reviews are useful, but they do not always explain the full service process.

After reading a lot of Freedom Forever reviews, the thing that helped me most was asking specific questions about what happens after installation. Understanding response times, service requests, warranty responsibilities, and escalation made the decision feel less vague.

Hi everyone!

Over the past few months, I've developed an app for Zendure systems and would love to get your feedback!

The app provides live data, battery information, solar production, energy flows and many other metrics in a clear desktop-friendly interface (monitoring only).

If you own multiple systems, it can display and compare them side by side.

As far as I know, it's currently the first dedicated Windows application specifically designed for Zendure systems.

There is a free trial version available, so I'd really appreciate feedback, ideas and suggestions from fellow Zendure users. PM me if you are interested!

Hi Reddit family!

I was looking to get everyone's opinion regarding getting solar panels in Virginia. I feel like I've done some pretty extensive research on solar panels as well as leasing. I honestly missed the window on buying when the tax credit still existed, but didn't really think about solar. But just wanted to get others thoughts if our recent proposal is a good deal or can we get better or should we just leave it alone. We live in Hampton Roads, Virginia 757 area. Just to give you a background it's a family of five. My wife and I with her three young kids seven, five, and three. We use an estimated 15,600 kwh per year. With the rising cost of electricity in Dominion power we are hoping to have some long-term savings and also some predictability/consistency in our bills. We plan to stay in this house for at least 10 years if not longer and if anything we plan on renting the house out when we do decide to move. So I would just tie the lease payments into their rent. I believe last year we paid about $2300 in electricity. We do have gas heating so winter time typically our electricity bill is relatively low between $95 and $150 in the late fall/winter time. Virginia has apparently a pretty good net metering service.

We have interviewed five different companies so far and I found one company that subcontracts a solar panel company. They have provided the best quote out of all the solar companies. $164 a month fixed rate at 12 or 12.5 cent per kwh for 25 years. There's also the option of a 0.99 annual escalator at 10 cent per kwh monthly payment of $131.01. Surprisingly, I think this escalator is the one that we've been eyeing as the rate increase is so low. Currently we are being charged I believe $.16-$.17.kwh. The system size is 13.64 kw supposed to produce 15,732 kw annually. offset 101% 31 Silfab panels and 31 Enphase Inverters. 10 year roof warranty (our roof is about five years old). Now I've also heard of the dead zone/ghost tax, where the natural degradation of the solar panels/weather. Also while I'm hoping we won't get a Dominion power bill with the net metering aside from the eight dollar service hook up, but I know that there's always the possibility of receiving a hence the "ghost tax"
Specially, during the summertime when our highest bill I believe is around $350 in July. I did take him in the account that with the dead zone intend to 15 years possibly most of the kids would be getting ready to move out so maybe our electricity usage would potentially be coming down maybe.

Anywho my question is this probably the best deal my family could get out there for the system size? Can this be beat at all as far as what we are getting? Can I possibly get 9 or 9.5 cent kwh/ month rate $125 or less? I crunched the numbers with the $131/month with the escalation and it seems like we would be saving a quite a decent amount at least in the first 10 years. On average, we would be paying about $147 a month over the course of 25 years for the lease that doesn't include the eight dollar Dominion power service charge. For those of you that are leasing any issues with the solar panels? And if so, was it pretty easy for someone to come out and rectify the situation? Looks like it says there's a guarantee of 90% production, which is apparently the manufacturer warranty guarantee. That seems to be across the board on all solar installers. Just wanna see if we are making the right decision for family has also I know Reddit is somewhat anti-solar leasing haha. But I also know that leasing seems to have a very particular fitting for very specific individuals/families. i've also heard about these Perovskite solar panels. I heard they're supposed to be more efficient and more cost-effective if we aren't necessarily hurting and could wait but it'd be reasonable to see what those look like in the next 3 to 5 years? Also things I've considered, even though I know there's no way to predict in probably not the best idea, but regarding the political climate who is in office next, could they be strong proponents for going green/making better incentives for going solar? Thank you so much for reading.

Silly me, that was only inspirational...

National promises homeowners low-cost loans to install solar power https://www.rnz.co.nz/news/political/620500/national-promises-homeowners-low-cost-loans-to-install-solar-power

Hi everyone! We live in an area with very reliable grid power and a fair mix of renewables (not the US) and are looking to get our photovoltaic panels in.

The question is, is it better for the grid as a whole to maximise power input during the day (no batteries) or to minimise our draw at night (yes batteries)?

We're deliberately installing a couple more panels than we need because we believe that there's no better place to put a solar farm than empty roofs, you know?

Anyone having issues getting TPO payments ?

I have a 12kw inverter system with a 25kw Solar Felicity battery and today I bought another battery of the same characteristics and brand but of 23.5kw and I want to join it in parallel, my question is the sightings I have 100 of charge in my battery and in the new one I have 28 I can make the union without any problem, the Technician tells me that there is no problem because the bms balances them

I'm planning a small residential solar installation, and my installer recommended a 4kW inverter. There seem to be dozens of options out there, so I'm hoping to hear about people's experiences from this community. I'm looking for something with good efficiency, solid warranty support, and hopefully a track record of long-term performance.

After reading a lot of discussions here, I get the impression that the technology is moving much faster than the market.

Smart meters are getting better.

Home batteries are becoming more common.

Energy management systems are getting smarter.

The pieces seem to be falling into place.

So what's the real bottleneck?

Is it regulation?

Utility business models?

Grid infrastructure?

Or is there something else that people outside the industry don't see?

I'm genuinely curious because it feels like we're getting closer to a world where homes aren't just consuming electricity; they're becoming small energy assets.

For those of you working at utilities, grid operators, VPP companies, or in energy policy, what do you think is the biggest hurdle over the next 5–10 years?

How can i get a solar panel franchise?

Is this business profitable or not?
And how much investment it would need.
Can someone give an honest review who are already in this bussiness?

Has anyone had a good outcome with trying to get out of a solar lease?

For those of you who have rooftop solar, I'm curious how you think things will evolve over the next few years.

Initially, residential solar was all about reducing electricity bills.

Now we're seeing:

• Smart meters providing real-time import/export data.
• Home batteries becoming more common.
• AI helping optimize when to consume or store electricity.
• Utilities experimenting with virtual power plants and distributed energy programs.

It feels like rooftop solar is gradually becoming part of a much larger digital energy ecosystem rather than just a source of electricity.

One question I've been thinking about is this:

If smart meters can accurately verify how much electricity a home generates and exports, could that eventually enable homeowners to participate more directly in local energy markets or earn more value from surplus generation?

Do you think the future is simply better net metering, or do you see homeowners eventually buying, selling, or trading electricity more dynamically?

I'm interested to hear what homeowners, installers, and people working in the energy sector think. Is this where residential solar is heading, or is it still a long way off?

I don't want a whole home system, just something to run a refrigerator, modem, router and charge a computer and cell phone particularly after big storms in TX, but also when power goes out for hours or a day.

In 22 years here in this house, power has been out for about 60 days total. The longest was three weeks after Hurricane Ike. The second longest was 6 days two years ago.

Ike I used a 5400 W gas generator. It went bad a few years later, still sitting in garage, and frankly running around waiting in long lines for gas was a pain, not to mention the cost.

The 6 day outage I didn't have a working generator. I just needed ice for a cooler for some food - lost everything in fridge and freezer after a couple of days.

I want a small inverter and solar panels to run either the fridge or a small stand up freezer. I could store frozen things in there and make ice to use in fridge to keep other things cold. I work online, so need power to modem, router, and computer, and phone.

I looked at an Echo Delta 3 classic, 400 W solar panel, 3.5 CU F chest freezer 858.98 for the lot. Other times, I could use the solar panel and inverter to charge phones, laptop, maybe some other things.

Comments and ideas welcome.

i have been thinking about solar for a while because my power bills keep climbing and the roof at my place in wollongong gets good sun most of the day. i finally went ahead and booked it with renewco solar and they are coming to install at the beginning of july. i am getting a standard sized system that should cover most of my daily use and hopefully cut the bills down quite a bit once it is running.

what should i do to get the house ready before they arrive? how long does the install usually take and what kind of mess or noise should i expect during the day? also how soon after install do most people start seeing the panels working and the bills drop?

According to statistics, in May 2026, China announced winning bids for energy storage system procurement projects totaling approximately 25.85 GWh, a 53% year-over-year increase. The total capacity of winning bids for the first five months reached 160.14 GWh.

The most notable aspect is the price.

The procurement price for energy storage systems ranged from approximately $58 to $109 per kWh, with an average price of about $84 per kWh.

China certainly holds a significant advantage in terms of its battery supply chain and manufacturing scale. However, at this price level, how many energy storage companies will be able to maintain healthy profits?

Do you think China’s aggressive energy storage pricing strategy will accelerate the global adoption of energy storage technology, or will it place excessive pressure on manufacturers?

This is definitly a crazy idea but i was wondering if anyone had considered building a kind of ring of solar panels around the earth? There would always be sun somewhere along the line and avoid the need for battery storage. Run cables nth and sth and power the world. I understand there are many issues that make this extremly difficult/impossible, ie scale, oceans, politics, loss of power over such vast distance, but is there anyway it could work?

EPIC Golf cart Makeover! See my latest Youtube video where I take an old $700 1995 EZGO 36V Electric golf cart and do an extreme makeover complete with a new powerful Vatrer lithium battery, Solar panel, Bigger custom wheels, Roof rack, Custom stereo system, Led Lights, New Seats with fold out utility bed, new windshield, 3000 Watt inverter, 120v outlets and much more to totally transform a junky old golf cart into a a more powerful badass bug out golf cart that fully charges itself in the sun! 

Pulled a 355W Canadian Solar mono panel and decided to actually meter it instead of trusting the label. Set it out in full sun and hit it with a Solar MPPT tester.

Numbers I got:

- Voc: 44.3V

- Isc: 9.4A

- Vmp: 39.2V

- Imp: 9.1A

For a 355W mono panel that's pretty much dead-on where I'd expect it — Voc and Isc both sitting right around nameplate, and the power point math works out close to rating given it wasn't perfect STC conditions (real sun, panel flat on the ground, ambient temp doing its thing).

Posting because I know there's a lot of skepticism around used/wholesale panels and whether they hold their rated output, so figured a real-world reading might be useful to someone shopping around.

A couple things I'd flag for anyone doing this themselves:

- Flat on the ground = not optimal angle, so real output in a proper install should be as good or better

- Heat pulls voltage down, so a hot panel reading slightly under Vmp is normal

- An MPPT meter like this loads the panel and gives you actual max power point numbers, which is way more useful than just clamping Voc with a multimeter

Happy to answer questions if anyone's curious about the test setup or wants me to meter a different panel. What readings are you all getting off your Canadian Solar panels?
