When asking yourself “How much solar power do I need?,” you first need to know how much power you need to run the appliances that you want.

For a 2kw + required power why do we need only 660w panels? What if you run a 1500w motor on that 660w system?
I want to build full grid 230v 50hz and like idk 100-1000 amps
Thank you for this video. I understood everything you covered ( which is a first). Now I feel like there is hope for me yet.
This is the best solar calculator I have found https://www.realcostofsolar.com/
So since my computer runs 24/7 I use 18,000 watts a day just for my computer? lol That doesn't include my 3 monitors ;/…Welp, I'm screwed. lol
Why do you skimp on the 12/24/48 volt explanation?
But if you play a computer game, it draws more power from cpu and gpu? So it varies? Do we choose the maximum of the GC output?
Ever heard of ….Dreamcatcher?
Fantastic video and information. Thanks 🙂

This is great! Liked and subscribed
Many thanks very clear great help thanks
Very thorough, thank you for taking the time out to fry a few of your brain cells!
Its very useful
Thanks alot!! This video was very helpfull and proffesional performed. Tgis wil help me and my family when we moving off grid this summer. I live in Alicante, Spain, so we have 230 sun days:). I will need water pump for the storage tanks, bur i think that is not a big problem
New subscriber let's c what u got simple living high thinking RSA
Thanks heaps mate!!!
This would have to be the best explanation on solar set ups and needs on the net.
You have a sub right here 🙂
WOW! This video was very useful! THANK YOU!
Should not WHEN you intend to use units also be considered, for large units, such as Residential central air conditioning all night in a hot humid Florida summer, or an oven/stove in evening, or electric heat thru the night? Is there instances for sizing, that one must work backwards? Such as these, then figure how much energy storage is needed and they from there, back up to buffer of days with no solar potential to run stuff and THEN to the array total wattage? along with other less amp usage all whcih could kick on at various times, such as Water Heater or other stuff, especially after sundown. I suppose it is advantagous to control certain usage to peak solar potential timeframes, such as if you have a shop and want to run a table saw and air compressor or arc welder or other big amp draw… do it in day and do not allow range, or other items to run, such as water heater or AC maybe, to balance out and not overdraw … all to reduce battery storage cycling and usage. PS: I am just trying to learn all this and it gets confusing. I prefer chemicals over electricity stuff…. I avoid such SHOCKING material.
I also wonder when battery storage will take quantum leap forward, as it may. or whether we shall ever see super-capacitors for such long term energy storage of coulombs
Couldn't you just look at your meter and that will tell you how many kWh's you are using daily
Hi, if I want a system with 6000W, I should need X panels at 12v, if I want to run the same system ate 24 or 48v does the number of panels double and quadruplicate also?
Wth that hair dryer lol.
Would this tell me how many batteries do I need?
what about just looking at your electrical bill monthly
I need to run 3000 watts continuously, help! I want to power my HPS lights
Thanks for the video I had a question regarding consumption of a refrigerator, the plate says 350 Watts but after a week on The Kill a watt meter it shows 1.5 kilowatts per day. Which is around 63 watts an hour.
Hi! You are the dude, i want to ask.. I'm going to buy fev 285w PERC- panels, they told me, Perc-panel is the best. Is that so..? I'm beginner, but very exited to learn more about solar power! Could you help me..?
Awesome video. Thank you for your help in understanding what I need to do prior to buying solar
just check your past bills. they shall tell you how much you have used on a monthly basis.
I knew next to nothing about electricity and solar power when I found your videos. I had just researched enough to know what watts, volts and amps stood for! That and the basic components of an RV solar system, panels, controller, battery and wires. Your video explanations are so clear that I learned what I needed to know to make a wise purchase when I am ready to do this. I know that I will not install it myself, but I wont be in the dark as a consumer. You are a born teacher! Thanks so much for taking the time to share what you learned from your research and experience in installing your system.
For home use, looking at the electricity usage on my bill would give me the total per day.
Hello. great video.
I have three s/panels 180w combined – a 2000w inverter and 5 batteries 410ah. I power a tv. DVD and l.e.d lighting…
Q. am I over doing it a little?
I live full time in a converted long wheel base van all yr round in the UK.
That is way tedious… why not mist talw.your electric bill and divide that by # days per month… do that quarterly to get an annual amount
Being new to RVing and diving into it by building my own van conversion I literally have know way of knowing how much power I'll use per day. My biggest power draw most likely will be my cooler/fridge, computer and TV all of which I hope to run on 12DC. My plan is to live full time and I will be solo but since my activities include various mountaineering activities year around as well as self contained bicycle touring i'll also be traveling/staying in all weather/temperature conditions. So since living in an RV is not the same as unlimited power usage in a house I'm lost right off the bat. My best guesstimate based off watching YouTube videos would be around 400W panels but I'm not sure if I'll have the room on my Transit van, any suggestions?
The second of your solar videos I've watched and just want to say you're the best! You make everything so clear I don't feel overwhelmed anymore. Thank you and keep those videos coming!
Very thorough instructional video. Nice.
Thanks mate. Great vid.
Thank you! At least I have now idea.
TALK SLOWER, PLEASE
Having been a full-time no hookups RV'er for 5 yrs I believe the biggest question is: How many zero solar days do you want your batteries to get you thru?
thank you
