can it be implimented ?

can i battery be charge during discharged same time i know its a stupid question but it dont hurt to ask thanks.

 

i know its a stupid question but ...

You just can't help it can you?

No, solar panel on a drone would cost more energy to lift it than it would produce.

 

It feels like we have a new "RK"
I wonder if he is back with a new name ?

 

By the way Battery cannot be charged and discharged at the same time.

No, but a large enough panel can supply power to the load and the battery simultaneously. A smaller panel could contribute some of the power needed by the load and reduce the battery's contribution.

As noted, neither arrangement makes much sense for a flying device because (except in rare circumstances) the panel cannot make enough power to compensate for it's own weight. I suppose the drone could use the "hop" strategy where it lands on the ground for a while as the battery recharges with the solar panel, and then make a brief flight before it has to land and recharge again. Could be useful when there is no other charging option.

That covers it. No, not going to happen.

No, this one's English is too good.

 

ok thanks guys and sorry for the trouble caused my apologies.

what is rk

No trouble at all. In fact, small changes in technology might make it interesting. I'm thinking of the so-called "printable" solar cells that were touted a while back. I haven't seen them on the market so I guess they haven't panned out yet. Point is, something useful might not be too far away.

RK was a troublesome member here a while back. Forget about it.

 

Can we please stick to the topic here and not digress?

This is what you had asked about:

It is possible but the mere fact that something is possible does not mean that it can necessarily be easily achieved.

 

thanks so much , se it can be done they did it why not us

have 2 sets of battery
use 1 battery while other charges then change channle to switch battery and let the old battery recharge and other one take over

 

A simpler approach that saves the weight of one battery is to use one battery that powers the vehicle and is recharged whenever there is enough light.

 

will solar panel strips work ? on phantom 3 size ?
or if i have to i can make extended frame like wings so i can add longer solar strips to make 12v or something

 

Probably.

You want the highest milliwatts/square cm and the the highest milliwatts/gram that you can afford.

As for the voltage from the panel and the charging method, you need to start with the battery voltage. Not sure whether anybody on this forum knows much about the motor and controls.

 

Assuming you could manage a flight time of, optimistically, 10 minutes on one battery charge, then you would need a solar panel capable of recharging the battery fully in 10 minutes to carry out your plan. I think that would require a monster of a panel: too heavy for the drone to lift .

 

depending on the load on drone , if not much wight is added then the flight time is increased to 30min as usual and adding solar strips they are not to heavy.

the phantom 3 advanced can lift more then 1kg , can lift a small dog up.

 

I do not think the panel at the power you require would be around a kg.

 

As a starting point, simply work out how much power your drone requires to stay airborne and this will give you an idea of the size of solar panel needed to make any significant contribution. I suspect it draws >>100W, have you seen how big a 100W solar panel is? But, of course, it's much worse than this when you take into account the additional weight and actual power output of the panel. Furthermore, the panels will act like sails so you will be consuming even more power due to constantly fighting against the wind.

The only reason it's viable for a fixed wing aircraft is because the aircraft is essentially a power-assisted glider and unlike your quadcopter doesn't require all that power just to keep it in the sky.

 

Please correct me if I am wrong but this should be your battery:

• Battery type: LiPo cells, voltage: 15.2V, capacity: 4480 mAh, power: 68 Wh, With built-in 4 LED indicator lights to show how much power, that is remaining at the touch of a button.

The battery pack is intelligent and a 65 Watt battery pack. Note the use of the word "intelligent" meaning a smart battery meaning it requires special charging. A battery pack weighs about 365 grams or close to 13 US Oz.

Now do the math, go find a solar panel that can charge that battery. Keep in mind associated needed electronics and weight of the solar panel.

The guys who built and designed the solar powered aircraft had a little more going for them than a basic drone. As mentioned the solar plane was basically a powered glider. You have everything you need to figure this out.

Why in the world are you comparing this to your drone.

By the way, in this fight there is no us, us says it cannot be done. There is only you.
