Tim's basement (filled) with powerrack(s)?

Use the grid for charging off peak only, there are no EU regulations that I am aware of that mandate a requirement for a home to have power connected AND USED. Winter you need the grid because without around 5x more solar or a wind turbine you will not have enough energy, so the grid is not really an issue to consider. Build and make a difference...

That is exactly my plan of attack. Only use the grid off peak for charging or direct use in winter or when the battery runs out of juise.

You need to explain the bigger picture ... How many solar panels have you got , Are they on your roof ???

What are your driving habits ??? If your car is only used at night you don't need a powerwall , just charge the car directly while it's parked at your house during the day ....

Explain everything ,  it could save you a lot of wasted time. ....is grid electricity cheaper at night??

Right now i only have 1450 cells tested and put in holders. Around 2000 cells u tested. And 161 laptop batteries. And BIG plans.

I have a roof where the south side is just big enough for around 4500wp of solar panels. Those and the electronics will be bought right after the winter.




Right now i need to solder the packs together and keep testing and collecting cels.

As of the first day of 2019 i will start with the roll in leadership at my work so there is a lot of time in preparating that and also preparations of christmas and new year.

My girlfriend who lives with me is currently until end winter following in the eavenings lessons. So i need to do more of home stuff.

I work in a full continue system. So i have early shifts, late shifts and night shifts.

Here in Belgium we need to pay taxes if we have gridconnected solar pannels. And those taxes are around 70% of what you save in electricity. In a few years they change our meter to a 'smart' meter and then you sell your electricity for almost free and pay the full stuff when you take it back. During night and weekends our electricity is cheeper then during piek hours (day hours).

I hope that I answered all the questions. If not, please reask. Thanks

I figured he's planning on showing the "whole" process. From nothing, to something, to finished. Even the basic stuff he's covering (assembling of the table for example) he's making fun and entertaining.
Perhaps he will explain why he choose each component and the reasoning behind each choice.

I hope that we don't have to wait weeks for the next video, tho. Altho, I understand that life things can inhibit production. Hopefully everything will progress smoothly  Smile

Yes. I aim making a full covering entertaining video playlist on youtube. So i and others have fun. I post all my succeses and failers so it is fun and a learning proces.

Befor next weekend there will be uploaded the next video. Part 2 of the preparations ?


You have to pay taxes if you have grid attached solar panels?   Seriously?  

So you pay for the panels, install them...  supply power to the grid and have to pay for the priviledge to do so?   That is insane.

Yes. 5000wp solar self installed cost 5000€. Lets say in 20 years, you need 1 new inverter. So total cost is 6300€.

Taxes on an 4000w inverter is 100,58€/kw = 402,32€ every year to pay tax. Electricity cost saved = 800€
Monney saved in 1 year = 400€. Payback time is 16 years...

Can you provide a link to those tax laws because my Google fu is failing me. Seems most bizarre.

I can confirm Tim's tax problem ...  have it also  Tongue

It's a temporary (read permanent)  tax to ofset the costs made by the previous government which (over)subsidized solar installations.

Interesting. I read that as the charge is only applicable to those people who's meters go backwards when exporting solar energy, thus cancelling out the revenue generated by the electricity companies to the equivalent of your entire production. Net metering. Those who have separate export and import meters are not subject to this charge. Presumably their export rate is far lower than the import rate (most markets this is true), so I envisage that charge as a method of evening the field. Is that not the case?

Does Belgium also have feed in tariffs?

No. They are working to roll out 'smart' meters. The roll out should be on 1 januari. But software problems came up and delayed that until march. I think that it is so they can give us monney for the electricity or. Pay monthly based electricity instead of yearly calculations of your meter readoud. Eather way. Not benefitical for grid ty solar systems.

There are similar moves afoot here in the UK, the end of new FiT approvals and a failing project to introduce smart meters. This is combined with an intention to bill based more on connection to the grid (as a service charge) rather than billing based on consumption (/kWh)

Either way, there is now no method for small scale generators to "sell" their surplus - fortunately theres plenty of zero export and grid limiting inverters being made available.

Use it or lose it.
