Question for anyone who might know. If i bought this (or the renology 100w panel) would it even be feasible to use for my 8,000 btu portable air conditioner?? I would use my ecoflow 2 generator to connect the panel to my generator and just use it. (Even if its for say 4-8 hours per day) i just wanna use less electricity with the air conditioner in the house. Even if it cuts bill 25% -50% (for the air conditioner alone) ill be happy.
Any info helps. The ac uses 115 volts. The 100W renogy says it makes 500Wh a day. So i assume even with a full charge generator and then instant energy from the solar panel i should be good for a few hours no?

Your 8k btu ac will use 300-500 watts to maintain the temp (if its an inverter midea u ac) so running it for 6 hours is 1.8-3 kWh of energy you need. 100watt will be too small. Buy 2 350-450 watt pannels and it'll cover the whole ac bill.

Thank you for your reply. I appreciate it. New to solar solar (besides the cheap little solar security lights and whatnot).
Thanks im just trying to see what i can do to take away some of the electricity strain from the ac unit. I was thinking even a 200W renogy panel would be good. It states 200wh per hour so if i get sunlight for 5-8 hours it would still only be up to 1600kw. Which is still under your estimate.

I cant yet afford 2 300-400w panels. But question for ya. Would it still be worth it for me if i did end up just using the 200wh panel for a few hours a day to minimize the power consumption used? I still feel like i could maje it work but id have to continually unplug and plug back in the ac unit when generator is dried out.

Again thanks!

Most newer AC's have a timer feature where you can set it to turn on and off. So for instance if its hot in your room you could set a timer feature to run it for 3-4 hours (~1KWh) after you go to sleep. If your AC is properly sized to your room you should be able to cut your electric consumption to 0 with 2 panels but will probably have to set the temp to 76-79F.

If you live in a hot climate with a lot of rain at some point during the year you could collect that water and run a pump up to a drip tube on your roof and cool down your roof & your whole house/room that is above that section of roof.

So for me im in a house in sunny Cali. My room is a detatched room the air from central AC BARELY makes it to my room. Its essentially non existent. My room is the hottest room in the house which is why i got my own ac for it. But yeah my biggest goal is to cut down on the electric for now. We want full solar but need to replace roof First. Who knows how long that will be. But for me myself for my room id like to have my own panel or 2 to be a bit less reliant on the electric for the ac at least.
We have my ac set to 72-73 and yeah it only turns on when it goes above so its not on 24/7 technically since it stops and waits til it gets hotter again.

Not unless they are rated close to the same

So i have this mini Tower powerbank CyberPower CP1000AVRLCD Intelligent LCD UPS System, 1000VA/600W, 9 Outlets, AVR, Mini-Tower, Black https://a.co/d/6zy8g5Q
can I just hook up to this solar panel system without buying anything extra?
And how many panels I need for 4 hours sunlight for this powerbank? Thanks.

No, most lead-acid based UPS battery backup systems from the likes of CyberPower or APC do not have a solar inverter built-in. You need to be looking for the newer class of Li-Ion battery stations, many of which DO take solar input (but not all of these function as UPS...)

If you get direct sunlight (not through glass) you can, but you need a way to use the energy, via a battery of some sort

Do you have battery recommendations? I kind of want to get a small panel, pair with a battery and use it for small things to get the experience

I purchased the refurb bluetti EB3A - I'm also new to solar so don't have recommendations. Someday hopefully I'll have a bunch. Haven't got it yet.

I would definitely recommend getting a LiFePO4 battery instead of Lithium Ion, they will last far longer in terms of lifespan.

5-8 hours of sunlight is not 5-8 hours of peak light that will actually produce what the panel is rated for. Any shade, any weather, clouds will drop output of the panel greatly. And if you want to get peak output, you will need to reposition and follow the sun. You will need more than what they say the panel will produce to keep up... also, you would benefit from a better solar charge controller to get the most out of the panels, im not sure of the controller included in the ecoflow, but if it is not MPPT, you will have further loss of energy . If this is a real goal, look into buying separate batteries, a charge controller, and an inverter. But by the, you will likely be spending much more than any cost savings you will realize.

Portable power/solar have their place, but try throwing a power meter on that AC and see what it costs to run and then calculate what it will cost to buy a panel, mount it, wire it and the cost of the ecoflow. It might take years to realize this savings.

These small panels and lithium battery combos really are best in places where no other power is available (sheds, motorhomes, boats, camping, offgrid). And for power hungry applications it is more economical to go with larger panels.

Tha k you i value your input. And i am actually planning on buying a reader to see how much power the ac alone is taking up. To do the math on it soon.

I'm not familiar with that AC unit, but the type of units used on campers have a huge inrush current when they start up. So even if your invertor is rated for the average draw it will blow the circuit breaker. There's a device made to help this called a soft start which dampen that starting current.

There's a lot of comments in this thread that make is sound like hooking up solar panels is easy peezy. I would encourage people who are interested in doing this to Google Will Prowse solar and listen to his youtube channel and his web page. You need to have the proper fuses / breakers in place, etc.

Listen to this!!
If you are near power don't waste your money on Solar panel and battery thinking it will save you money. You can maybe get 1kw of energy for 2+ days of direct sunlight on a flat roof with this 100watt solar panel. 1kw is just an average of cost of .18 cents of energy produce by home electricity.

I'm going to agree with you on this. My buddy bought a system that they told him would get rid of his electric bill. They also said he would be selling power back to the electric company. They put panels on every square inch of roof, sold him 4 Tesla Power Walls, the whole nine yards. Everything all-in was right at $100k. His $600/mo electric bill is now $300 on average. So for $100k he saves $300/month on average. At that rate, his break even is 27 years! Frankly I think he should sue the company that sold it to him. Solar is so inefficient, it's stupid
