Hi Paul how big of a solar panel or how many do you need to make to power a home 900sq ft and what do the panels connect to in a home so all your outlets work ? Do you need a panel in each room in the house or how does this work? Does the gov provide free solar panels and installation?

[@Oman_Sea_and_Beach]

A new real time calculation of these type of solar problems using Artificial intelligence is now available online but these services are not free. For example if a human can analyse it in 2 to 3 months then this online system using AI will analyse it in one day...

Studied all these in the faculty of energy engineering, an entire subject in a semester, but neither I understood by reading the book myself nor understood the explanation from the professor. This video summarized almost the entire book in a video and very well explained. Thanks for such straight forward simplification.

[@matthewcovington2699]

I’m a NABCEP board certified inspector for PV systems and about to have a degree in electrical engineering in February. And this is one of the more in depth Solar centered videos I’ve ever seen. Absolutely amazing. I will definitely tell our design people about the pvcase tool as well, it sounds great. Thank you! I plan to tell everyone I work with to watch this

[@sampleoffers1978]

Find a metal or element that has same frequency as the usable spectrum and build lid for solar panels.

[@matthewcovington2699]

@@sampleoffers1978 they’re multilayer filtering by different colors from the spectrum. That, so far, sounds like the way that’s working best, but I could be a little out of the loop by now. Idk the physics behind what you’re talking about, but it sounds good. Frequency is an odd thing to try to discuss with people when it comes to physics. Fringe made it even harder.

[@deped-cebucityrolandoarane5913]

As a science teacher, this video helps me further understand the concept of laddering of electrons and energy levels and I can simplify this to my students.

[@me0101001000]

I hope you'll talk about other types of solar cells soon, especially dye sensitized solar cells, QD solar cells, and perovskite solar cells! I'm extremely passionate about those! Plus, you can do some pretty impressive performance enhancement with concentrators.

[@SnowingNapalm]

Yeah simple mirror concentrators but then the increased heat significantly damages the cells quicker reducing lifespan which means you have to research cooling for panels to increase efficiencys of protection of panels like how many layers deep you'd like to go... solar evacuated tube heaters for steam power can use the heat energy of the photons bombardment to drive physical motions which can be turned into electricity via motor run as a generator possibly being more stable long lasting but as you need to clean panels from dust the same is true for polished metal mirrors or even plastic coated reflective paint mirrors... materials science matters as well as the patterns of cycle and how many "losses" tax your useful power generation... now heat is technically energy and could be reabsorbed but however grand and efficient you design something the more it takes the more expensive it gets to make so you must weigh the value of cost to efficiency ratios and find your favored system but not exclude other systems just for being fuel powered etc just allow, which is key word allow people to maximize the efficiencies without limitation of the previous "we could never do better than that" stifling phrase there may be a time to discourage for saftey reasons but to encourage and support instead to provide required safety so no innocent bystanders are harmed , i mean they got micro nuclear power plants running satellites drifting out to explore space for us sending back the information as best it can getting increasingly harder to track as it gets further and further from our solar system 😂

It's just amazing!

Thank you so so so much! I'm a high school student, and I was studying for AP Physics, and I did NOT understand solar cells at all. this made me understand and I explained it in detail to my friend, and I feel as if I can really apply it!

Excellent and comprehensive solar primer! Everyone interested in PV systems should watch this. I think you could have used higher numbers for some of your efficiencies. Modern inverters, especially for large installations, are typically >98% efficient. And modern commercial solar cells are >25% efficient and climbing.

[@WW-hr1hd]

Thank you so much for this excellent video! I had a PhotoVoltaic system installed on my home in 2018. Everything was handled by the solar contractor, so I didn't get to learn much about how the system works when it was installed. This video explained everything I ever wanted to know about how my system works. My system is tied to the grid but does not have a battery included in the system. As such, it's possible to have net metering with my system. So for several months in the summer I routinely produce excess electricity which I sell back to my utility, Xcel Energy. Net metering coupled with the Time of Use rate structure allows me to use electricity when rates are at their lowest, and to sell electricity back to Xcel when rates are at their highest. So I actually make money off my PV system in the summer! 🤑💰

[@DanielBrotherston]

The interesting result of the 30% limit on PV solar cell efficiency has an interesting result: heating your home using thermal solar collectors can capture much more energy than using PV to power a heater. Although when you combine PV with a heat pump, the gap gets a lot smaller...although with current technology there is still a gap. It's also much cheaper to store heat energy...you can do it with a large insulated water tank.

[@sampleoffers1978]

Confusing to me is thermal imaging can see heat, so why can't a panel be calibrated with filters to use heat to displace electrons? There's a lot more heat available at night and as waste product, than light. Fire is heat and makes light though.

[@beyondfossil]

Sure, solar heat for bathing and washing dishes is very good but general-purpose electricity so much more useful. Moreover, there's only so much hot water a household can use - it's just not an ongoing thing in a daily cycle. On the other hand, there *is* ongoing electrical all day long every day from computers, TVs, refrigerator/freezer, lighting, cooking, etc. Also storing heat is more lossy than electricity in batteries. If the house has a utility that does solar net metering, then they can use the grid as an energy store. Eventually homes will just have *both* photovoltaic and thermal solar collectors. If it can be done economically, the best is to have the heating pipes directly thermally coupled underneath each of the solar panels to collect heat and also cool the panels to significantly improve their electrical efficiency. Can get upwards 15% more electrical production while directly producing hot water at the same time.

[@ursa0607]

[@jgon12]

He made it easy to understand but behind the production and engineering of the semiconductor and what goes on inside the cells it's not easy lol most are 20-30 percent efficiency so they still not perfect.

This is very insightful with simple explanation, easy to understand, well done!

[@kenyarborough812]

You should have mentioned anti-island in the case of an power outage, and it adds cost, protects the line workers from electrocution. Since it costs more, most installs won't have ant-islanding, meaning the batteries will not power the house on a grid power failure.
