I CANNOT THANK YOU ENOUGH FOR THIS ANALOGY! I have been struggling to understand the difference for weeks at work and this 6mins video made all the difference! :D
I've just started a new career within the solar industry, so I'm still getting used to the basic concepts. This video was great and I learned a lot, thank you!
This is pretty simple. Whenever you find something labeled in its watts that’s how much power is being used by it per second…so first, you just convert it to Kw to determine it’s usage. Example: A 300w GPU. Make it Kw, so just move its decimal back by 3 or divide by /1000, whatever’s easier for you. So 300w is .3Kw. That’s .3Kw per second. Then see how many of that is being used in an hour. So that’s one second, that is there’s 3600 seconds in an hour. So multiply that .3Kw by 3600 seconds (1hour). That’s 1,080. So 1.08 KWh. Granted my pc will have more than just the GPU. A one Kw solar panel system could run the GPU for basically ~1hour. A six KW solar system could run it for about ~six hours.
practical help: what is a difference between these two companies 1. Each block is equivalent to 50 kilowatt hours (kWh) of electricity and is available for $4.92 net cost per month. So when you subscribe to two blocks, you’re supporting 100 kWh of solar energy for only $9.84 per month or just 33 cents per day.versus Versus 2. The initial credit rate on your bill will be approximately $0.04 per kilowatt-hour (kWh) and will remain at that level for the first 36 months. Starting with the 37th month of continuous enrollment, the rate will increase 1.5% annually; A 1kw subscription to solar energy will cost less than $8.35 a month** Please help what is the difference between these two offers?
When you turn on a 100 watt bulb in your home it actually consumes 100 watts per seconds but your electric company charges by the hour so that would be 100 watts every hour. When you produce electricity from your PV system that 100 watts bulb would consume it every seconds, so a 100 watts bulb will drain a total of 100 X 3600 ( 3600 seconds in an hour) = 360kwatts in that hour from your batteries.
You said we're pushing electricity into the bulb faster. Is that true? For example if the voltage was the same, but the amps were different. Is it more accurate to say that we're pushing a higher volume of electricity into the 100w bulb?
Fair point. It is not a perfect analogy. The voltage is analogous to how hard we are pushing the electrons, not volume. So slower electrons being pushed hard can be same amount of power As faster electrons being pushed less hard.
I don't mean to be pedantic when I ask this question but, when you refer to the speed of electricity, don't you really mean the amplitude of current? Higher the current, the more electrons are flowing past any particular point at any given time - therefore more power being delivered. Speed of electricity is only ever talked about in terms of it's frequency i.e. Hertz, which for all intents and purposes never changes in a typical system.
Power = current X voltage. So yes. Increasing current increases power as long as you don't reduce the voltage. Just like the flow of water in a pipe. More current = more power as long as the pressure is not reduced.
So if i have a 1500 watt solar generator why is the batter only rated for 1069 wh instead of 1500. In my mind i could use 1500 watts for one hour. But by this rating itd be less.
@@SolarQuotes Water flowing through a pipe is not even remotely close to flow electricity. Electricity is readily available at the source, the way to increase flow is to increase the load or draw.
@@susandenyme9691 I agree is it far from the perfect analogy. But for the purposes of helping solar and battery buyers visualize the difference between power and energy it is helpful - as many comments here seem to suggest. The intended audience is not engineers or scientists :-)
@@SolarQuotes inaccurate analogies is not the best path. I have worked in instrumentation/Electrical engineering design for quite some time. So many people challenge what is being done simply because they never had it explained properly, do not understand or found something they Googled claiming it is more accurate. There is no need to be engineers or scientists to have it explained properly. None of us where either when attending school
