Hey how long can you run a 2 watt LED on a 12 volt deep cycle battery before the battery is completely dead? or how many amps per hour would a 2 watt led use? ruffly speaking? Thanx Dale...
ive taken a 7.2 rechargeable battery and a 3.8 watt solar panel to power two light in my room is that acceptable? how long do you think it will take the solar panel to recharge it?
@DeviloftheHelll They can reach 60 Lm/W for the warm white(3000K),can instead 15-20W incandescent light .and the quality has become more stable after a long time
hi, we have been looking at ideas to build a outdoor light suitable for camping that will light up an area out side tents(better that garden lights) using the sun during the day and providing light at night. also to create a light that can be charged by the sun during the day that can be attached to a tent roof to provide a night light inside the tent for the kids. would this sort of panel work for that or could you provide any ideas.
This would be a great way to illuminate caves during the daytime at no cost except the original expense. Also to illuminate dark rooms and cellars at no cost except when very cloudy or at night. Of course batteries could supplement for those occasions.
You have a source for the panels since you priced them? Make, Model and distributors.
Nice vids btw.
I don't know what I'd do with a color LED with a remote besides making a Jumbotron in that backyard for movie day. He he. Trying to save money not throw it away.
@aczeclipse Did low power indoor LED lighting popular or will more easy to be acceptable by the customer? if it's true,i would like to make some sample for you to make a test!
The Light out put by spectrum intensity of an LED diode,is capable of higher spectrum light radation,than the Solar radation,needed to power it,Not crap! phisics! You go look up Effishancy!
"The Light out put by spectrum intensity of an LED diode,is capable of higher spectrum light radation,than the Solar radation,needed to power it,Not crap!"
If you don't believe me, try it. Even if the panel converted 100% of the sunlight to electricity (world record is about 40%) and the leds converted 100% of that electricity into light (maybe up to 85%), you'd still only get the same energy out as you put in.
With real (<100% efficient) components, you'd waste 70% of the power each cycle.
Hey there Dan, I would be interested in finding a couple of those remote controlled LED lights used in this video. Are you willing to share your supplier?
I see what you mean, never thought of that, my idea was the pressure is released at the bottom in an enclosure, thus the water level will drop at the top, wich can be refilled using another tank above the main tank, which is filled during the day with solar power. I'm trying to find a way to get power at night without batteries!!!
think of this dan, a very heavy weigh rises slowly in a tower filled with water, when it reaches the top, it falls in the air generating power, the only problem is hgow to get the object back into the bottom of the tower, as there will have to be some pressure loss, ie water.
possibly a solar panel pumping water into a higher water storage tower during the day !!!?
"a very heavy weigh rises slowly in a tower filled with water"
Unfortunately, to get the weight into the bottom of the water (even with a perfect and frictionless valve and no pressure loss) you will have to displace all of the water upwards (the water level rises when you put something in the bottom) and lifting the water will take more power than the buoyancy can generate.
For more details about that sort of thing google 'Donald Simanek'.
"possibly a solar panel pumping water into a higher water storage tower during the day "
Yes, and then let it run down through a turbine. That would work. It's called pumped storage hydroelectric when it's used large scale. Compressed air is also a possibility, or even a large flywheel.
LOL The green white green order of the storage boxes on the high shelf hand me thinking you had some Heathkit equipment hiding out up there. But I guess not.
Have you tryed regenertive loop? power from one pannel running the lights that power the second pannel? the idea is like the way power is boosted in a spark coil in an automobile.
"power from one pannel running the lights that power the second pannel?"
Research the meaning of the word "efficiency".
"like the way power is boosted in a spark coil in an automobile"
The power is not boosted, the voltage is, with a corresponding reduction in current (amperage) and a slight drop in power because they're less than 100% efficient, like all machines.
@wickedweekend Yes, but slow. The 7ah batteries charge well, these will charge any 12v battery. I would suggest a CHARGE CONTROLLER, even though they are not powerhouses, these panels can overcharge a 12v battery over a few days if you forget, trust me:-)
Another type of LED lighting I have seen is automotive lighting.
I have an LED strip light that replaces fluorescent tube lighting. The maker claims it is "as bright as a 60W bulb", but I think it is actually brighter. I think it's designed for internal lighting in a bus or something.
Yeah, that's the standard package I think we should already be using extensively. Not enough people know, which prevents wide spread usage of this technique. They just don't think about it, it's easy to just keep using what we have and watch Idol and Dancing with the Stars.
Please make a video about the connections and electronics needed to make this work with the wind power and some batteries to be able to really power a house...
Most people can't afford the big installations yet, so this is a good way to start. Other then that it is important that the public can see and learn that solar energy is useful for big parts in the world and that it will pay itself back at places with the right conditions. I like people who put a lot of free time, energy and money into making these kind of videos. People like Dan and Denise are doing great work, maybe you should sponsor them so they can show what you like?
Over what period of time did you calculate the exact costs?
How long do you think that the modern day solar panels will last? According to a professor in the Netherlands they will last for about 30 years, and the costs of a complete system will be payed back in about 10 years. And that is in the Netherlands, even with a lot of cloudy days with rain. I believe the professor who is also a former astronaut from the space shuttle and a multiple winner from the solar challenge race in Australia.
Thanks Dan these will work great in the subterranean Green house I'm working on. would they work in series after a dusk to dawn light mmmmm? I'm trying to set up a LED grow light system with automatic turn on as we loose allot of the grow day in the winter here in Pa.
Keep feeding the thinkers as we shoot for green power.
Yeah, I'm pretty much obsessed with tech these days.
Green power, microcontrollers, all things hackable. Always trying to expand on my electrical engineer non-degree. Learning useful stuff is a good way to cope with the things you can't control :)

Also, that doesn't even make sense. Stringing together impressive sounding words is not the same as actually understanding what you're talking about.
