The Earth intercepts a lot of solar power: 173,000 terawatts. That’s 10,000 times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy? Richard Komp examines how solar panels convert solar energy to electrical energy.
Lesson by Richard Komp, animation by Globizco.

We do not need deserts in order to get solar power. Put solar arrays above car parking lots. The United States has 24,000+ square miles of parking lots. Bonus; you get to park in the shade.

There is a "typo" in 1:22. While it is correct that N-type material has more electron and P-type material has more holes, they are by themselves neutral. When we put the N and P type silicon together, electrons in the N material tend to travel across the junction and occupy the holes in the P material, which leads to positively charged N-type semiconductor on the top and negatively charged P-type semiconductor at the bottom (according to the video). Thus the "+" sign should be on top and the "-" sign should be at the bottom.

But i think the credit is due to the early discoverers, as Solar panels and spectroscopy, among other things, wouldn't be possible, hadn't the interaction and correlation between light and excitation of electrons been discovered.

Thats the best in the world, and cost hundreds of millions to produce. Nuclear and coal are much cheaper than this technology. So if you want every household to spend millions on solar panels that are only 5% efficient, go for it. But don't force it upon anyone. I personally prefer nuclear as it is clean. As solar technology develops it will be a good option, but right now it is very expensive an inefficient.

I've recently become a huge proponent of portable solar panels. They're a good transition to full-scale solar to prove the concept on a small scale that can be scaled up later. I have four portable panels and some power banks, and take them everywhere to show them off and get people hooked on solar, especially skeptics who want to see it for themselves before making n'y decisions. It's great!

They need to be able to make the light the panels absorb...either without heat, or heat that powers magnetism enough to suspend light over the panel....Lenses can magnify light, and spectrums can be duplicated...Panels should usable indoors and stacked up...not chasing the sun, needs to be the evolution. Glowing tee shirts convince me light can be harnessed for closed system panels, probably from chemically or magnetically treated particles.

There is a technical mistake @ 1:18. The video mentioned that semiconductor doped with a donor material will have unbonded electrons, and semiconductor doped with an acceptor will have extra holes. That is correct, but this will not make the side with more unboned electrons negatively charged and the other side positively charged. This is due to the number of electrons and protons are still equal on each side. but then, due to the concentration gradient, electrons travel to the other side and combine with holes making the other side negatively charged. The diffusion stops due to the created electric field. So simply, the - and + signs shown in the video are wrong. its the other way around.

The N-type silicon (very thin top layer) actually has a positive charge due to the phosphorous impurities donating an electron to the Boron, which is added to the bottom p-type silicon. This creates the electric field needed for electrons to flow in one direction rather than recombining.

How much did you pay to install them ?
@astikrasgabas
@astikrasgabas 4 роки тому
@yeahSOwhat Depends on how many kw they installed but for 4kw it can range from £3,000 to £5,000. Maintenance is minimal since all they do is sit there. The only maintenance needed is cleaning them to prevent shadowing. Durability can also last up to 30 years easy.
@astikrasgabas
@astikrasgabas 4 роки тому
@yeahSOwhat No.1. Not everyone can afford it. 2. Oil companies still need money. 3. You still need some kind of backup incase there is not enough energy being made.
@genericasianperson6405
@genericasianperson6405 4 роки тому
Well going by some research you usually start seeing profits after around 7 years of getting a solar panel due to really cheap electric costs
@astikrasgabas
@astikrasgabas 4 роки тому
@@genericasianperson6405 The year that you start to profit from pv panels depend by the country and the climate. E.g. it will take longer to start making profit in Germany because electricity is more expensive as they tend to use more green energy compared to something like France as a lot of their energy is nuclear which is dirt cheap, and by climate especially during winter as the pv panels tend to be covered by snow especially in North regions. In winter you will tend to use more energy than what pv panels can produce.

@Bruteforcedj
@Bruteforcedj 5 років тому
No we need sustainable energy. The population at present and the growth of the population will deem renewable energy such as wind and solar insufficient. For personal use such as cars, homes and private businesses yes it will work. But as the sole power source is absurd and will result in blackouts due to insufficient supply to demand. We need fusion energy, we are focusing too much resources to the wrong area.

Well I have built many Data Centers. We don't depend on utility electricity. We always have an UPS to backup electricity failure and right after that we have a Generator to power up within minutes. I have a site where we purchased 1000 liter fuel for Generator 6 years back. But used as little as 80 liters in these years. But preventive maintenance of Generator n UPS is done monthly. So we will have utility power as backup, or maybe for nights. This way we can at least slash down electricity bill to 1/3 for individuals. This may reduce the fossil fuel usage by utility companies. First thing mentioned in this video, the political reasons and businesses who take profits by selling power is the main reason.

The illustration of positive and negative charge formation is misleading (referring to 1:21), when electrons from N type flows into the P type, it generates a negative charge on the P type and leaves a positive charge on the N type semiconductor.

We have our own solar power system in our house here in the Philippines and it's working 24/7 since we are not connected to the electrical company. Because of this we don't have to pay our electric bill. It's really amazing having unlimited energy with your appliances without thinking about your electricity bill, but you need to have a maintenance once or twice a month for its durability and longevity for usage.

Actually here in the UAE, KSA's neighbour, a small city and research center called Masdar has been established for the aim to be green. My school took us for a trip there. There is a whole field of solar panels for electricity, the subway is lighted with skylights and uses electric cars. Also, the buildings don't use paint so they won't waste money and effort on painting buildings.
