Here in Spain, if I've understood correctly, you are taxed on anything other than a 'small' solar setup (though what constitutes 'small' seems to be a mystery) and the tax you pay is the equivalent of what you would have paid to buy electricity from the grid, plus an additional payment to the government for the inconvenience you cause them. This would explain why almost nobody has solar - not only can you never recover your costs, but you're losing money all the time...
Also true for germany - for newly installed, larger systems you're required to pay "Erneuerbare Energien Umlage" (renewable energy tax) on power you use from your own renewable solar system. Luckily we tend to use numbers so we know larger starts at 10kWp.
You could probably increase the efficiency of your panel a bit by increasing the angle at witch it is installed. Probably somewhere around 30° would be optimal, depending on where you live. Especially in wintertime this should increase the yield.
The ideal angle is your latitude, in fact. Where I live that's about 22°. Germany is a somewhat higher latitude. This angle actually makes a big difference (on the order of a few percent surface area), but of course used to matter more, when panels where more expensive.
AKS Maybe for where you are but on the equator optimal would be flat on the ground (0°) and the further you go north or south, the more the angle would have to pay increase.
Even if you are 20° off from the optimal tilt angle you still get about 95% (at least in total energy over the year), so it is less important than one might think. It does change however how much energy you get during certain times of the year. Steeper panels mean a little less optimal for summer (where you will still get most energy), but more electricity during spring and autumn (and winter, but yield there is maybe of fifth of typical summer day yield, mostly because of the shorter days, so optimizing for winter is pretty pointless).
superdau I know, but it’s an almost free 5%. Btw: laying your panels very flat on your roof means that they will collect dirt and will reduce their performance further.
Here in the Netherlands you can ‘install’ an inverter up to 600W by plugging it into a normal outlet. The inverter won’t output anything unless it’s connected to the grid.
That's also true for all grid tied inverters over here, however they sadly still need to be hardwired to be up to our local codes. Sadly, because this also means you can't easily disconnect a malfunctioning one. Since the ones writing the specs are the same people the code requires you to hire for a hardwired connection I don't think this will change any time soon…
Brilliant video Bitluni, love all the funny bits, and full of info and useful facts! An interesting setup using the micro inverters instead of a single main charge controller and inverter. Makes me want to get this set up in the UK even more now - there are a lot of 30)W panels on eBay which are a bargain if you get a good one.
If you live in the Northern hemisphere, find your latitude in degrees,, e.g 51 degrees north, angle you panel to that many degrees and point it due south.
Well I expect you will make an arduino guided panel mount that changes its position in order to face the sun all the time. Maybe you could adjust horizontal and vertical angle by having one pivot point in the middle of one side of the panel and two stepper motors on rails the other side. Would probably have to draw this in order to make it clear. This is an idea I have, but am not able to do it because I am lacking time and especially knowledge :P
Did you expect the manufacturer to let you see inside the inverter? I don't know what they are trying to hide anyway, there are diagrams of inverters around anyway, though that looks a tidy unit. Tilting the solar panel up a bit should give you slightly more power, though maybe not a huge amount. A few linked together should help a lot. Flux capacitors use far to much power lol.
Your electric meter was used in our country when I was a child and most of us used a magnet to stop the rotation of the disk inside the meter to reduce the electricity bill at the end of the month! 😂 Proud to be an Indian! Electricity employees found that and replaced every meter with digital meters now
Thank you for the video. I am sorry to say that microinverter setup will not pass inspection with your powermeter. It worth to buy “grid tie inverter with limiter” 1kw cost 250euro, then you will be able to extend your system later. 250/1kw < 150/300W It is better to calculate all the staff eg pannels, inverters, batteries for €/kWp. Current prices is less than 0,3€/Wp for each component.
Do you have to have some mechanism to prevent solar generated output going out to the grid if the grid is down? As I understand things in the UK one can't legally just connect a panel to the mains circuit as then a repair person working on a down grid could get shocked, but perhaps your meters or otherwise prevent any voltage leaving your house. Most interesting & informative video. Thanks for sharing!
Very interesting video as always and I am glad you still have some lives left! However, the payback time for a system such as this will be longer than simply adding up your savings until you match your costs. Instead of buying the system you could have invested this money in savings and this potential return needs to be factored into your calculations. If I remember correctly you can calculate this in EXCEL using the PV (Present Value) function.
Number 5 from the movie "Short Circuit 2" procured (stole) a Die Hard battery from a car after he was attacked by thugs and its main battery was damaged. It kept him running just long enough to be rescued by his human friends (with a defibrillator no less LOL!)
*Looks at his awkward power lines* Well, most devices work on DC just fine ;) I've got the older(?) 248W variant somewhere around (yep, also potted) and was rather disappointed - at least with my external power meter the efficiency seemed kind of meh. Should still pay off if you can can keep cost for legal installation (electrical and panel mounting/approvals) at a reasonable price.
Pull a cable here in Spain we have a lot of sun all year. Here until recently we had a tax for putting solar panels, corrupt politicians. Greetings friend.
@@duncanx99 A new "Real Decreto" has been approved that has a net balance system, in which they pay you for the electricity by discounting it (excluding power line tariffs, that is). However, they simply discount it from your bill, and it can't reach 0 €. Still unfair, but that way it was approved.
US is not better - first adds 40% tarif to give less of a rebate afterwards. Oil lobby? In Latvia we pay like 1/3 of electricity bill to "green energy" of which 2/3 goes to natural gas cogeneration plants (which is one of the worst (in emissions) electricity production methods in the county since 70ish percent of electricity comes from hydro. So when I have a chance to grab cheap new panels from Asia it will be cheaper in the long run if no one brakes them, so more like 10¢/kWh including batteries instead of 15¢/kWh grid power
@@ArthursHD Please explain how you want to get to such low kWh prices as posted. Even with the cheapest option for batteries (LiFePo4 with about 5000 cycles, so good for 20 Years) the price won't get below 20cents (and even that takes knowledge). Solar power is cheap I don't doubt that but storing the energy isn't. Small example: I assume a power usage of 1500kWh per year for one person. For Latvia you would need at least 7kW of solar panels to have enough power in 11 of 12 months of the year (actually 7kW produce more anually but you to size for the winter and 12/12 months you would need to double the solar power to 14kW). Let's say you will have 7kWh of battery storage (you will need to limit the charging power in the summer, since LiFePo4 should not be charged with more than 0,25C). So around 6000€ if you do all yourself. With 5000cycles the batteries will be good for 35000kWh so it will be good for 20 years. For 6000€ you could buy 45000kWh of energy (0,15 US cents per kWh). Now you still did not buy any inverter they will break down three times in 20 years that adds up to 1500€ more. Anyway the prices up there are the very lowest possible, most people pay two or three times that because they don't calculate to the end or hire somebody else to do the work. I can only recommend to buy solar panels without storage if you are still grid connected and connect those panels to the grid to get money or lower the electricity bill.
If there is a black out then you need batteries. Power workers have been killed by generators feeding power back to the power lines. This could do the same thing.
I thought those old fashioned meters would run backwards. If you heat your water with electric, perhaps the simplest way to utilise the solar electric would be to feed directly into the immersion heater and not connect to the house system.
Nice work, but if we have a digital Énergie meter and the load power is less than the pv production what will happen ? i think it will count as a consemption.
Now make a solar tracker: it will make your - for the Lack of better engineering terms - camel back production more flat... as added bonus your ROI will increase a lot.
This live power plug reminds me of the ElectroBOOM video .... Is the Inverter also active, if it isn't connected to thew powergrid ? Because this would be a really high risk. Imagine tripping over the cord an getting shocked by the live power plug coming from the inverter...Good video anyways.. :)
All inverters do indeed shut off the AC output when theyre not connected to the grid, at least the ones legally sold in Europe. They need AC from the grid to sync to, they cannot run standalone.
@@DerHeilendeLotus Okay bei den Netzsynchronen kann ich mir das vorstellen. Die anderen schalten wahrscheinlich nicht ab. Dann ist das mit dem Stecker nicht so schlimm.. :) Aber wie im Video gesagt wäre eine richtige Installation natürlich schön. :)

Bitluni :) great video as usual. I've heard in Germany there are record breaking temperature's these days and hence ... top Solar input into your panels, have you tested then to know if they truly reach the Theoretical 300W ? Or is the efficiency you mention on the video the maximum one ... Also though you explain that the panels were a clearance sale I think one can find solar panels for around 0.5$/W but the 100€ for 300W it's Truly a very good price!
Nice project, and 5 years doesn't sound like a lot of time. What happens when you exceed your power comsumption and start feeding electricity to grid? Will Polizei come and force you to draw more power? :D Keep in mind that fridge doesn't use power all the time, only when it's cooling, and I can't think of any other device that draws power all the time (except stand-by power of all devices), so it seems kind of risky to use that. And you definitely should put some effort into organising all the wiring, because it doesn't look convenient and safe. Are you thinking about expanding this instalation, meybe some battery back-up?
Totally illegal in Australia. Boo but i do have a 6.36kw system on my roof. 5 years to pay its self off. .26c/kwh power cost. .23c/kwh feed in tariff avg 21kwh feed in winter time
