Solar power question

[ReefQueen]

Does anyone know if LEDs would work with solar powered things? I found some dirt cheap clip on solar powered fans that would be perfect for above the tanks to deal with this heat, but I am not sure if they will work. I figure they will turn on automatically during the day when it is hottest, and turn off at night when not needed, then i wont have to plug them into the reefkeeper. I may just order 2 of them to see what happens

Depending on the output of the solar panel right? And the power consumption of the LED you are using.

Well, they use visible spectrum light, so they theoretically can. Just not sure how useful they would be to power a fan from just hood lights. They are still extremely inefficent. Take however many watts you lights put out and multipy by 2% or 3% or so. That's what you would get from the panels if powered only by your rank lights.
Dropped a bag of ice in my sump tonite. Dropped a few degrees off fairly quickly


Cheers!

A good solar panel, operating at peak efficiency, would produce maybe 200W. I would hazard a guess that a typical reef aquarium would require 4-5 of these to operate normally... with all solar panels operating at peak efficiency 24 hours a day. Probably not a realistic scenario.

The OP said a clip-on solar powered fan....200 watts? Not a chance. 200 milliwatts mebbe

That's not true anyway, I have 315w panels on my house. I made something like 2.19 mega watts last month. Still owed 6 dollars. Lol

 

[ReefQueen]

Darn, I was so hopeful I wouldn't have to waste a plug on the reefkeeper lol. Oh well, back to chopping up egg crate so I can take the glass hoods off the tanks one down, one to go!

Are you sure it was *mega*watts? That is an impressive solar system for a house.

Cheers!

 

[Triggreef]

Well then whatever Mwh stands for. Mega watt hours I guess. I made 2.16 of those.

Must've been a good month. I'm betting you can't count on that every month

 

[AllSignsPointToFish]

MWh must be thousands of kwh. in other words, you made about 2000 Kwh, enough to power a small household...also about half of what is needed here in the south...Lol...assuming you like air conditioning, of course.

 

[Waterjockey]

Well then what does Mwh stand for? Cuz I made 2.16 of those.

My apologies. I edited my reply...probably around the same time youreplied to my knee-jerk reply ...I was thinking megawatts-per-hour.....not per month when I originally said "no way". Then I realized that probably sounded rude (not my intent), edited it...but you had already seen it and replied.

Nice sized solar setup...would like to know more about it. Again....sorry...as I work in the power industry, I automatically assumed megawatts *per hour*, not thinking over a month.

Cheers!

Well on the ot, I hope it's better over the summer so I can get credits carry me through the winter.

 

[Triggreef]

Lol

Lol no offense taken. I also edited mine right after I posted it for the same reason. I'm still learning the solar lingo my system was only installed in December. That's my best month so far by a lot.

Also, it's 58 panels. LG is the make, all have micro inverters. 25 yr warranty on the inverters. And 20 yr on the panels I think. It's supposed to cover 101 percent of my usage for the year. The cost of the loan is about what my electric bill was, maybe a little more. Obviously the faster I pay it off the more sense it makes in the long run. This month my pool pump and central air comes on so I'm hoping it does better.

 

[Waterjockey]

Lol

And still owe the power company a few bucks....crazy. lol. I'd love to ask more about your system, but won't derail the op's thread with anymore ot stuff.

Cheers!

I hope the maintenance costs over the loan period don't offset any potential savings. As you can probably tell, I'm a skeptic. lol

Derail away, my question was already answered and we don't want a perfectly good thread to go to waste lol. I too am curious.

Cooling fans would be good to use if using halide lighting.

You could use a splitter on one of the PC4 outlets so when your daytime lights turn on so does a small fan. That's what I did for a short while until I bought a chiller.

Or whenever it is 90 degrees in your house lol
