Topic: Solar panels set to be mandatory on all new buildings under EU plan - page 2. (Read 1179 times)

Are you trying to break a record on how many times can you be wrong on a forum?
In what galaxy is the peak electricity usage at night?



Every state despite being 3000 km north or south uses nearly the same pattern, and I don't think 6 PM means nighttime anywhere!


Irrelevant, if you would have actually read the proposal it doesn't say at any point any of the buildings should be off-grid.


Simple, it will not be mandatory! We're talking about an EU program here!
It's like saying that Germany will ban ICE from 2050 and you come and ask what would Uganda do!

And where did you get the information that batteries for solar systems need to be changed every 3-4 years?
When I was considering a project for my country house, I planned to use AGM type batteries (for use in regular and long-term deep discharge mode). We produce in Ukraine, at a very reasonable price. At the same time, the battery has an estimated service life of 18 years in buffer mode. Accumulators type SMG Solar OPzV (factory "VLADAR"). 18 years old, but not 3-4 years old!

The problem is not with solar panels, but with the battery to store the electricity. The main issue here is that solar panels generate power only during day time. And the peak electricity usage comes in the night time. So there is a requirement to store electricity. And batteries that are needed here can be expensive, needs constant maintenance and need to be replaced every 3-4 years. And during the last one or two years, the battery prices have gone over the roof, due to the rising prices of raw materials such as Lithium, Nickel and Cobalt. 

I agree - not everywhere there are comfortable financial conditions and state support. But conceptually - this technology, in the near future, will become available to a wider population, both in terms of availability, price, and ease of construction. I am very sorry that in your country the state has not yet come to understand that it is necessary to diversify energy sources, including through private solar "stations". I am sure that either the state will soon come to this, or private suppliers of solar panels will offer convenient financial programs - this is a natural development of the market.

    I think it's really goods idea that solar panel will be mandatory, but sad thing is some people can't afford to install solar panel because of to much high cost but otherwise they can save and help the ecosystem. More people planning to have a solar panel cause it really use specially having a typhoon an we can not deny that there's an electric interruption, so to those people who had an solar they will be lucky that they still able to use electricity using solar panel.

What about countries that dont have any state support programs ? For example there is none in my country. I have already calculated, that it takes 8 years minimum to start getting profit from solar panel installment. 8 years is a lot. I dont think people even live more than 10 years in one flat, but those who do, usually are middle class or those who think 1000 times if they can afford to spend that much to install solar panels.

Let's count the real data. My average monthly electricity consumption is approximately 710-730 kWh.
This is approximately 24 kWh per day. Like a lot. But I do not consume gas, hot water. The apartment (approximately 120 sq. m.) is all powered by electricity - a boiler, an oven, a microwave oven, a hob, a refrigerator, a washing machine, TVs, a robot vacuum cleaner, several air conditioners and much more.
In total, I need 24 kW / h (this is the maximum value, because in summer consumption drops to about 530-550 kW / h). Or 24 / 8 (daytime hours) = 3 kWh. Now we have available the simplest single-crystal panels British Solar BS-535M-110, this is about 500 W / h at a price of 8300 UAH / 35 (dollar exchange rate) = 237 dollars. To fully cover the need - I need 6 of them. Let 2 more - to compensate for losses and other things. Total 8 x $237 = $1900. Plus additional lubrication - about another 1,500 dollars. Total - 3400 dollars. This is 3400 * 35 = 119000 UAH.
Average cost of electricity consumption = 1250 UAH/month. (again, I take the winter period, the price of 1 kW / h  = 1.68 UAH)
Now we consider the payback: 119000/1250/12. It turns out approximately ... 7 years and 9 months.
BUT ! This is a calculation with maximum performance and a noticeable power margin, and secondly, there are state programs that allow you to save up to 50% of equipment costs. The total payback of the project in reality will be approximately 3 years. It seems like a long time, but .. But it pays off, in a quite sane time, and then you just save.

PS. Obviously, someone will ask the question - "where do you hang them in a multi-apartment house ?!", and look slyly I answer - the format of the panels allows them to be fixed on a common roof!

Humanity has long needed to pay close attention to alternative energy sources. But those forces that controlled the extraction of oil and gas by all possible methods prevented this. Only the fact that oil and gas remained in the fields for only a few decades allowed us to tackle this long overdue problem.
Of course, it is necessary not only to improve solar panels, but also to constantly look for opportunities to acquire knowledge of the use of other alternative sources of "green" energy. The decision of European countries on the mandatory installation of solar panels on the roofs of new buildings is very timely. It must be taken into account that their profitability and efficiency will constantly increase.

This initiative of having solar panels is very good because it would be using clean energy, and it would be a good additional support for the normal energy consumption that exists depending on the country, where I live, electricity is generated by hydroelectric and thermoelectric power, I know that others countries use nuclear energy, which is the cheapest energy but it represents a great environmental danger, however for us in my country, acquiring solar panels is a very large investment, if the EU has a certain type of help for its inhabitants of Acquiring cheaper solar panels would not be bad, it would be helping the planet, I do not see it wrong, in any event it is good to have these backup systems.

In our country it was not that expensive two years ago .. now it is again getting expensive - - and also there is more need of solar panel because our region is very hot and we need air conditioning for approx 4/5 month a year. So investing in solar system is a very good option. The sooner the better.

That is basically what the crypto part is all about, you could do that, and for the housing it would not be bad neither. When the miners were asked to go on full solar panel or any renewable energy in Europe, people went mad and talked about all the other places that use energy a lot more.

But, the reality is that EU is trying to turn everything into renewable energy, especially after this Russia stuff they really want to do that. This here showing how they are making solar panels mandatory in new buildings shows that it is not just about crypto or miners, it's about the fact that everything new should go that direction and this is a proof that they are not anti-crypto, they are pro-renewable energy.

solar panel is expensive in some countries because it lacks and it'll give a constant power supply in any household so solar energy is good electricity supplier when you have the money two by two regional one so the future is changing and no one is making use of plan that is known as electricity generator in his house. Because solar energy supply light without noise why generator supply light with noise pollution so people prefer using solar energy most at times Rich people

Solar panels are the need of the time. Its the future, those who have taken the right decision at the right time are the real heros.
We have not done that till now. And we strongly repent. Now we all are planning to get a solar panal for our homes. That is the only solution for power outage.

Doesn't it seem strange to you that solar panels are being talked about right now? At the time when today's conflict between the USA and Russia takes place? Last year, everyone was calmly ill with covid and everyone was an excellent virologist. This year, all the people around suddenly became international economists. Last year, everyone was fine and quiet in the queue for gas to Russia, and this suited everyone. Doesn't it feel like we're being manipulated? And what will happen tomorrow? What is the new topic of discussion?

Making solar panels mandatory in all new buildings is good than waiting on the queue to get oil and gas from Russia. More countries will engage in such act in the future, because beyond certain point oil and gas industry won't be able to supply the growing demand. Now itself finding an alternate and working on the same is good for the future.

Europe has no other choice. It is not and will not be in the future! What is left to do to keep warm? Fire wood stove? Solar panels are still a modern form of electricity generation. This year they will be in great demand in Europe. Nuclear power plants are dangerous and if this option is considered, safety measures must be taken. What can be done here? Do not engage in nonsense and buy gas from Russia)

No, it's not like that.
Some really mistake the consumption a powerful video card has just because they are always compared with ASICs.
A video card that draws 250W will burn 6 kwh each day,  180kwh a month, more than what bakasabo consumes normally.

To put it as easy to understand, if you have 250W solar panels and 6 hours of peak sun on average you will need 4 of those panels and batteries to power continuously one 250W card. 200 videocards would consume 1200 kwh each day, needing at least 800 panels and batteries able to store at least 3/4 of those, around 900 kwh, so about 60 Tesla powerwalls..

I think that ain’t too bad, 5 panels could cost a bit when you are starting out, but from what I understand you are not going to spend another single dime on it ever again? So, your mining would forever be free? If that is the case, that initial start-up cost could be awesome.

I know a guy who does mining (gpu) in a small shed like stuff but he maxed out, he has like 200 gpu's inside that small shed, did it like that because he had a HUGE fan type of thing that cools it, hence if it is small enough, it would be easier to cool it as well, it’s not a freezer type of cold, but it is quite cold, like you wouldn't be able to live in that cold, it’s quite bad (well good for the machines). So, if he put some solars on top of it as well, that means this dude would get wealthy without spending another dime on it ever again?

It is interesting how things are playing out, due to the disaster at the nuclear plant of Fukushima of 2011 there was a very strong movement against nuclear energy all around the world, which lead to the suspension of the construction or the closure of nuclear plants, if politicians had not gotten fearful of nuclear energy back then Europe will not be anywhere as dependent on Russian gas and oil, so European governments are forced to take a suboptimal decision which will cost more money and will not be as effective, increasing the price of energy all over Europe just when we are going through a period of high inflation.

But in countries which have hot weather and the sun is up for approx 12 hours a day installing solar panels is a very good investment.
In subcontinent - particularly in India - the gov is providing subsidy for installation of solar panels. And also it is good for the those who consume lot of electricity. Those who made investment in early days have made decision.
