Who on fedi has adopted balcony solar?
-
@andrew773 I live in a condo so I don't have control of my roof or surrounding spaces. But I do have control of my balcony, which is on a corner with north and west exposure. Not ideal for solar I know, but the west end gets lots of afternoon sun, so we would like to harvest it if we can.
@Nichelle In that case even if grid tied balcony solar is not available where you are you might be able to find an off grid solution which will feed directly into a battery inverter combo. I do not own this product but to get an idea of what I'm saying - https://www.ankersolix.com/products/c2000-gen2?variant=53152183353674&ref=SolarGenerator4&selected=c2000-gen2-400w-solar-panel. Good luck finding something that works for you!

Who on fedi has adopted balcony solar? Since Colorado has paved the way, we are considering it. I would love to hear about people's actual experiences, how much power they have been able to harvest, any issues, one panel vs. two panels, etc.
Please boost for reach.
I'm planning to, but @balkonsolar can share a lot for sure.

@Nichelle I now have whole-house solar and before that I set up an off-grid power station with 200 watts of panels. I still have and use the off-grid panels and power station, but the amount of power it generates over the course of a year is truly minuscule compared to the needs of a whole house. 200 watts of panels will get you about 1kwh/day in good conditions. On average over the year, factoring in cloudy days and winter conditions, it's closer to .4 kwh/day. And then when you're talking about a power station scenario, your round-trip efficiency through a battery is optimistically 80%.
I lay out all those numbers, because it matters a lot for what you intend to use it for. It's kind of obvious, but maximizing solar panel wattage (total area), placement, and angle is HUGE. The If you're going to go small, it only makes sense if you need it for emergency power. Ultimately, for my setup, the ROI was 10+ years, which I suspect is true for most small solar + battery setups. For cost saving, a grid-connected setup makes way more sense, especially if you have a net-metering balcony solar program available.

@Nichelle living close to Berlin/ Germany. We have installed two panels with combined 950 Wp facing south and a 2 kWh battery/ inverter since some weeks. Reduces electricity consumption by 65% during summer (2 people, working mostly from home). I think it will have paid itself in 3-4 years. Big bonus: in case of blackouts, we have at least emergency electricity. Probably will add another bifacial panel for mornings/ evenings and maybe more battery capacity.

@Nichelle Just posted about it a few days ago:
https://ohai.social/@bigz/117072542575907648With two panels I’ll save about 250$ p.a. Investment of 400$ for the core system and 400$ for a smart battery. Located in Germany, latitude of northern Michigan.

After calculating the amount of power I can use during sun hours I dropped balcony solar, the utility company would have profited far more from my investment than I could.
Now using non mains connected portable solar, I started with one unit, added two extra batterys, with 4 500 watt panels I harvest more energy than I can use most days and evenings/nights..
Exception was Part of December January to March where I got almost no benefit.
I have cut my bills by about 65%.

@tehfishman Thanks for the numbers! We are connected to the grid, so will probably be using netmetering. I work from home, so am using power/running the A/C exactly when the sun is fiercest. The balcony isn't located ideally for solar (north and west exposure), and the panel will have to be mounted vertically (on the railing), but we hope to make a dent in the electric bill. We have been looking at BrightSaver for wholesale prices.

@Nichelle had balcony solar since 2020: it's a piece of sand, a microinverter, and a plug in the wall.
Produces 600W peak, saves plenty of electricity.

@ocramius Can you explain more?

@ToweroftheArchmage @chgowiz @Nichelle Waiting for it here in CA too with fingers crossed that it happens.
I have off-grid solar (300W and three 100AH batteries and more) but those aren't in regular use as 'balcony solar" would be.

Running in Germany since 2019.
Upgraded from two to four panels (& DC storage) last year without changing the meter.Was worth it then & prices have crumbled since.
Only red tape restricts it.https://burningbecks.wordpress.com/2020/09/13/zaehlerbremse/

@Nichelle
Got 2 modules in direction SE and SW. Baught also a 48V battery (20 kWh) and a controller, which regulates to zero grid usage and handles modules , bat and inverter.
Yearly grid energy changed from 800 kWh to 300 kWh.
In winter loading bat at weekend with cheap energy (have variable price) and runing all high power devices parallel . In summer harvesting over week and running high power devices serial. -

Wait, what... In the land of ultimate freedom you can't even put a solar panel on your house?

@bertkoor @ToweroftheArchmage @chgowiz @Nichelle Not these, not yet. Because reasons that include powerful private utilities and probably influenced somehow by the most corrupt administration in our country's relatively short history.
That said, regular solar panels remain a popular option for those that actually own their own homes.

@bertkoor @croyle @ToweroftheArchmage @chgowiz If you don't own your building, you can't put solar panels on it. Condos are tricky...you own the interior, but not the exterior, which is why the balcony solar regulations are clarifying what landlords and HOAs can require you to do. In Colorado, the regulations stipulate that neither HOAs nor landlords can prevent someone from having solar panels on their balcony.
