>Solar cycle paths are turning out as a succes
>Now the cyclepath with solar panels in Krommenie, the Netherlands, has been functioning for a year. The seventy meter long cycle track has generated energy for three households. The problem with damage of the top layer, coating, is already resolved.
There are still three places in the Netherlands, and two abroad, where a solar pavement is laid down. This need not be a bike lane, a bus lane is also possible.
'' A bus lane captures plenty of sunshine, a limited amount of time is used and you know exactly how a bus loaded the road. It can also be combined with electric buses. You charge the bus without contact with the energy from the road surface. That is a picture of the future. ''
>The 70 meter long road, called Sola Road, delivered kilowatt-hour in 9800. An average household uses in a year, more than 3,300 kilowatt hours.

Aint that pretty cool
It's not like there are plenty of houses nearby, which's roofs are empty, never covered by vehicles or trees and slanted for better sun exposure.
>>906842
>Solar cycle paths
For what purpose?
>>906842
why the government doesn't make it a standard to have all roofs be solar I don't understand. houses and buildings cover way more surface area than roads do.
>>906858
For this to happen, each owner has to consent, and each roof must have a system tailored to it. Compare that to a solar path or road system, where the local government just tears up the asphalt under its control and replaces it with regular blocks.
Homeowners will adopt rooftop solar en-masse when it becomes a good investment. Once it reaches that point, sales agents would hunt down people with no panels on their roof and pay them to sign up for rooftop solar panels in exchange for a cut of future profits. Even in areas where the government has utilities pay a premium for solar, this isn't quite the case yet.
>>906861
This.
Besides, solar panels make it impossible to put out a fire if your roof burns cause the firemen might electrocute themselves.
You can't really switch off solar panels on a basic level.

hey electrician bro to help out and spread a little bit of knowledge I picked up while working with people who do install solar.
>why the government doesn't make it a standard to have all roofs be solar I don't understand. houses and buildings cover way more surface area than roads do.
The government, america at least, cant force anyone to install solar panels. However local building codes and energy codes may one day choose to adopt codes requiring panels on all new buildings. As is I make tons of money on current energy conservation requirements.
>Homeowners will adopt rooftop solar en-masse when it becomes a good investment.
yes this, but from talking to solar installers the cost right now is too high and not enough return in the long run, that and the fact that the batteries used in the inverters seem to only last 10 years at best and then dump more money into it... maybe never get any savings.

There's no argument that traffic passing over the panels would block the sun, and accordingly the panels would produce less over the course of the day.
But at the same time, they would also cost much less to install, since the installation would replace a road construction operation.
If the reduction in installation costs is greater than the reduction in power output over the lifespan of the panel, those panels would be more cost effective than a more expensive installation of panels in a prime location.
Now, since these projects are probably balls-deep in government subsidies and individual green fetishism, it would be difficult to gauge whether or not they make sense financially.
>>907006

>>907018
There is no way in hell panels that need to withstand the weight of human beings could possibly be cheaper than pavement. Those things must utilize some hideously expensive glass.
https://www.youtube.com/watch?v=obS6TUVSZds
and nothing else to add.
>>907029
It wouldn't be cheaper than plain pavement, but it could possibly be cheaper than securing the same power output through dedicated solar panel installations, since you'd be piggy-backing onto an existing construction project and foregoing some of the installation work (steel frameworks etc..).
The main design problem, having a passable road surface that's also transparent and cheap, is a real bitch, though. It wouldn't surprise me in the least if it turns out that this idea doesn't take off even with green ideologists and entrepreneurial charlatans joining forces to back it up.
Personally, I think they'd have more luck with the following:
>self-sufficient lighting through the use of local solar panels and distributed banks of disqualified EV batteries
>passive, or nearly-passive, harvesting of thermal energy from standard roadways
>mass adoption of rooftop solar panels
>dedicated solar production facilities in sunny regions of the world
You guys are all fucked up in the head. The experiments have been going on for a year and they've concluded it is succesful. All your theoretical gibberish can suck my cock and die on exhaust fumes because reality proves otherwise.
>>907053
>experiments
>successful
Can you point out to the peer-reviewed scientific article about the experiment and its results? Was it really an experiment and not just some "evaluation" project whose reported results hinge on politics and not on the actual merit of this system?
So they could extract about 10kwH in a year from 70 meters of road. How much did it cost them to install the road? When would they have to replace it? Would a municipality not affected by green fever voluntarily pay to have pavement replaced with solar pavement?
>>906862
Asked a fireman about that. They don't care, unless you use sea-water the voltage isn't enough to cause a problematic current, since water isn't exactly a good conductor
. The only problem with the panels is that they may block the water a bit.
>>906842
>3,300 kilowatt hours.
Sounds like a lot at first, but once you break it down a bit a year has 8760 hours. That makes an average of 377W. Of cours the average for a solar device is never really high since it won't work at night or in dim light, but honestly, we are talking about how many sqare-meters here? By the look of it that path is 2m wide, so that would be 140m2. That's just an average of 2.7W per square meter.
So it works, but really isn't any good for the prize. It's better to just pave that thing normally and put some panels on a roof, where they can work under good conditions.

That seems like a really low power/square meter. Footpaths and cycling MAYBE just because they don't even need to design them to handle intense loads but the fascination with having to design around moving heavy loads like cars and buses I don't understand.

Half the output for something much more expensive so In the end they're just throwing money away since they'll never get enough money to pay for the Investment before the panels go kaput. And that's with cycling paths, If they were used In normal roads their efficiency would be even lower and they'd be even more expensive.
You don't have to reinvent the wheel, just stick the panels over the road as they did In korea, much simpler, efficient, cheaper and all around better solution but It doesn't sound as cool as putting panels on the road so nobody gives a shit.
>>909331

We put solar panels on our commieblocks instead.
>>909475
That's nice but you can only power like 4/5 apartments with that.
>>909592
I don't think the purpose is to produce excess electricity, only to shave off the tops of consumption, and possibly to drive elevators, ventilation, electronic locks and things in case of a blackout.
District heating from burning trash keeps the buildings warm, though modern 4-glass windows is likely going to cut this down to heating water.
>>909475
That seems like a really inefficient place to put them. Solar panels aren't cheap. I don't understand why installations don't mount lenses over the panels. As in, you can collect the light from 10 times the area of the panel, since the panel is the expensive part. You won't get 10x the power, but you've made your solar cells much more productive.
>>909475
b-but why not solar cell sunshades for the windows?
>>909331
i like this idea and hope to see urban freeways covered in this fashion
>>909317
why wont you just die already
>>909645
Because the lenses have to be mechanized to track the sun. The goal is to use large lenses to focus the light on a smaller solar cell, which means the lenses (or reflectors) need to track the sun across the sky.
So a lot of the reduction in cost of the cells is eaten up in increased operational and maintenance costs.
Still useful technology for dedicated solar power stations, but absolutely the wrong solution for "install it and forget it" type rooftop installs.
See https://en.wikipedia.org/wiki/Concentrated_solar_power for a starting point if you want to know more.
>>909647
It's particularly nice for bike paths because It also sort of serves as a cover against sun and rain but I still see It as something worse than regular panels on roofs. So I'd rather see Incentives for people to Install panels on roofs rather government pursuing this sort of more complicated project. Maybe I'd be In favor of this sort of thing after government had helped turn the regular Installations more feasible.

actually it just gets dumped back into the grid and the power company meters it. This way the power company doesnt have to build more generators. Studies by xcel energy have shown that just by helping to pay for lighting retro fits in offices and other upgrades xcel can save the cost of additional power plants and actually make more money in the long run... so chew on that one for a bit and think of just how many watts we really use.

>Rooftop solar is still a hundred times safer than coal and oil power because of air pollution deaths. Other ways to make solar power safer:
>1. Increase safety for all rooftop work (can reduce deaths by half or more)
>2. Rooftop solar tiles installed on new buildings might not have any more incremental deaths as opposed to panels that are separate from the roof tiles or systems installed that replace roof tiles before they would normally be replaced.
>3. Create some new installation system where people stay on the ground using some forklift or crane to raise and place a solar power system onto a roof. Have to ensure that the heavy machinery system is safer than the roofing process being replaced.
>Some responders online are in denial that people who work on a roof can fall off regardless of the reason they went up there. If I go up there to replace roofing tiles or go up there to install solar panels, the risk of falling is pretty much the same especially when the number of times being compared heads to large numbers like millions of times for each. As I noted in the comments, statistics show that 70% of fatal construction falls occur at height of 3 stories or less.
So basically if there were less stupid tradies sacrificing occupational safety for laziness or macho nonchalance, and their apprentices were less worried about standing up for themselves, then there would be far fewer deaths associated with solar panel installation.

The sunlight is. But the panels are not. And their lifetime is, sadly, somewhat limited.
So putting the panels in a place that yields better efficiency means that you get more power out of the same invest, or have to invest less to get the same power.
