Topic: Solar panels set to be mandatory on all new buildings under EU plan - page 4. (Read 1215 times)

I'm not that familiar with the technology, however, I'm in a Facebook group regarding electric vehicles and a few members had incorporated solar panels into their households. I've read that with enough battery capacity, you can get through the night without any major issues, providing that your consumption is within a reasonable range.

I reckon it would be a move based on the self-sustainability movement which has been around for a while now. Its clear that governments do not care about climate change as much as they say they do, but they do not ignore it neither. Plus, if you have a nation that doesn't require to get energy or oil from any other nation, you are 1-0 ahead of everyone, maybe gas too. You can't just build gas (as far as I know) or oil (again same) but you could get energy, electricity, from solar panels and wind turbines and even nuclear plants, which would be the move to go, then instead of regular cars, have electric cars everywhere, even stop the production of cars running on petrol, and you have such a big movement in your hands. Not really shocking move.

It's good to avail the solar panel  deals. The sooner the better. We live in the country where there is huge crisis of electricity.
Some smart minds have availed this opportunities a year ago - I repent for not doing this.. But now at any cost I will get the solar panels installed.

The use of solar panels as alternative energy is really needed today to cover electricity needs, the increasing need for electrical energy will certainly accelerate the depletion of fossil fuels that have been used for power generation, the use of solar panels may look cheaper, efficient and can save usage fuel oil or gas, at this time I see many who discuss the positive side of using solar panels, but does anyone know what about the negative side of using solar panels for humans and the environment?

Semiconductors are often temperature dependent, physical processes that affect their performance (resistance, leakage, etc.). But as I understand it, you do not live on the equator, which means that your territory belongs to warm rather than "extremely hot" countries, and solar panels will show themselves quite effectively!

"Solar panels are generally tested at about 77°F and are rated to perform at peak efficiency between 59°F and 95°F. However, solar panels may get as hot as 149°F during the summer. When the surface temperature of your solar panels gets this high, solar panel efficiency can decline somewhat."

I think it's fine for southern Europe that gets plenty sunshine all throughout the year, so just Spain, Greece and maybe parts of Italy. But what about the rest? The yield might not be as good in the areas with longer winters.

Maybe give companies in those regions alternatives. I've seen vids of small wind turbines that can be placed on the roofs and walls of buildings and those don't need all-year clear weather to be useful.

India is doing so much for the people. I wish our government do the same for us.
But the weather is so hot here and power outage is around 10/12 hours so we have decided to have less grocery from now on and will buy the solar panels. 

Here in India, the government subsidizes installation of solar panels for private households. I am not sure about the exact amount, but somewhere around 50% of the cost is borne by the government (but like any other third world country, there is a lot of red tape and bureaucracy to overcome). If the EU is also thinking in similar lines, then I don't believe that there will be much opposition. Anyway, in the long run the residents will benefit out of it in the form of cheap electricity. But if they want the private individuals to bear 100% of the cost, then I am afraid that it's not going to work.

No need to apologize, believe me, many in the EU do not know who all EU members are, who is in the eurozone and who is in the EEA.


No one can force a member state to accept something, but in case a member state opposes someone, let's call it a "common goal", it will pay fines or be denied funds from the common EU treasury. Hungary is the most obvious example of a disobedient member state, but it is a policy they pursue, and the people support that policy by electing Orbán four times in a row.


I am not in favor of forcing people to install solar panels on all new buildings, but in countries that have plenty of sun during the year it would really make sense - of course provided that the purchase of solar connectors and equipment is co-financed by the state.

You will still be dependable from regular electricity. Installing solar panels does not solve high electricity issue completely. Those who plan to install solar panels, I would suggest to consult with those who already have such panels and how they are doing in winter, when we have sun to less than 8 hours a day and panels are covered with snow.

nucular is the fastest and cheapest green energy that can power whole eu

Oh... in that case I erred and need to apologize for that. It is nice that the national parliaments need to approve these stupid measures. I am sure that the Green party dominated countries such as Germany would approve it, putting the citizens further neck deep in debt. More sensible ones, such as Poland and Hungary would refuse to do that. Stock markets are crashing around the world. Bitcoin has lost two-thirds of its value from the peak level that was reached less than a year ago. Inflation rate is in double digits. This is not the right time to further overburden the ordinary people.

I was thinking of installing solar panel in my house because electricity is too expensive now and we don't get electricity for 24 hours. I live in country where 7 to 8 months we have sunny season and summers are too hot. But your posts just shocked me that panels are best for warm regions not for hot. Can you explain with some references?

I think that limiting reliance on fossil fuels (Russian ones but also other ones) is very important to ensure that we're taking climate change seriously. While it can cost some money and probably a recession now, it will pay off in the long run because the effects of climate change can be very devastating not only for human life conditions in many places, but also to the global economy. Solar energy is clean, and relying more heavily on it is a good proposal. But it's also unstable (because it relies on sunny days, basically, and that can wary both within the country and between countries), so something else to back it up is also necessary.

That is correct. I am sure people who have solar panels installed would be doing the same. Now because in my country electricity crisis is a real trouble.
We are now seriously thinking to install solar panel at home because there is no solution to it.

If you only knew what stupid rules Euro bureaucrats are making up, you would surely remain in disbelief. Those farmers who receive financial support from the state will not receive it if they use hoes, they need to buy expensive machinery to produce environmentally friendly food


Iceland and Norway are not part of the EU but part of something called the EEA (European Economic Area), so I don't think this law should apply to them. In addition, every law passed in the EU parliament needs to be approved by national parliaments, and some member states will certainly not accept this.

Dont forget, that solar panels dont accumulate electricity, you cant install a huge power bank at home. You cant rely on them for 100%. At night, you will still be have to use "regular" electricity. If you want to get maximum from solar panels electricity, you would have reschedule your daily routine, move things like laundry, ironing, or things were electricity is used on a day time. Some people can do that, some will have to "partly rest at a day" and "work at nights".

And another limitation from the European Union on all it's citizens, why can't we decide anymore for ourselves on what is good and what is bad? Do we really need to be fully controlled by politicans. I understand that we need to switch away from Russian gas and Solar energy is one way to be autonomous, but do we need solar panels on every house? The first issue is that we already have a lot of regulations on heat insulation for new buildings. The building cost for a new roof already increase 30% just by new insulation everybody has to use, then we can add another 30% due to inflation in the last years, and on top of that we now need solar panels. Like this it seems that cost of a new roof doubled in the last 5 years, which is insane. Also in the summer it's sunny and solar panels should be profitable, but during winter we see almost no sunlight. How will this be worth it to have solar panels then? I am not against green energy, but why does it have to be mandatory?

It's a good initiative that more and more countries have been transitioning into energy efficient methods to conserve energy and electricity consumption. It's a nice move for Europe to impose this given that it will be beneficial in the long run. However, I think before they totally mandate very building to be installed with solar panels, they should first assess the capability of the owners to make it happen. Perhaps setting a considerable time frame would be nice so that they will not be shocked and be burdened with sudden expenses for installation of the panels.

Because as we all know, installing a solar power system could be expensive. While it is sustainable and cost efficient in the long run, they have to shed out a huge amount of money first. In addition, the return of investment will also not be instantly given. It will take years before they get their money's worth in solar panels. Hence, thinking about the financial matters should be in their list too.

Switching to eco-friendly methods such as retrofitting which they will require through solar panels will really be helpful in combatting energy efficiency gap and it will be healthier to the environment. It's just that there are other factors that should be considered too before they make it officially mandated.

Well... for countries such as Greece, Spain and Italy, solar panels should work, because there is bright sunshine almost 24x7. But the same can't be said about some of the Northern European countries. All I am saying is that the cost should not be imposed on the ordinary people. If someone want to install solar panels, then let him do that on a voluntary basis. If the EU wants to make it mandatory, then they can subsidize it. Asking the common people to pay the additional bill is not a very bright idea, when the inflation rate is in double digits.
