Q:Photodiode vs solar panels?
Yes, so are camera sensors. Except in cameras they're specially desgined to reduce noise.
Q:selling solar panels online - a good idea?
My guess is that you might find everything related solar power at www.okorder.com.
Q:Solar Panels in the 200 Toyota Prius?
Hi, the solar powered-venting system is not air conditioning, it is simply a venting system to attempt to balance the interior temperature of the Prius with the outside temp when the interior of the Prius is at least 68 degrees. This is an optional system and is available as a stand-alone option for $800.00 or $3600.00 in conjunction with the navigation system. The solar roof is integrated into a full function sunroof, but the sunroof can be opened without using the solar venting portion. There is a separate portion of the system that will allow the driver to turn on the electric AC for three minutes, if there is enough stored charge in the nickel metal hydride (NiMH) hybrid battery. The AC is not linked to the lead acid battery, and is run by the NiMH only, not the gas engine. The NiMH and lead acid are two separate power systems. The solar panels do not power anything else in the Prius and do not boost the power to any of the systems. The solar venting does permit less energy from the NiMH to be utilized for AC at the next startup. For trivia, the EPA will not allow Toyota to install the solar venting system on Prius with the top package V (#5). The EPA feels the Prius is too top heavy with all the additional sensors required for the radar guided cruise control and all the other high tech components in the top end option package, just FYI.
Q:Solar panels.......Earning potential.?
it depends on your solar panel, but you can sure supply most if all of your electronics and electric stuff in your house on a sunny day. If you want to know exactly how much power it supplies and how much $$ you can save you simply have to calculate how much power your home consumes per day/month. I know of people totally reliable on solar power for their home and I too will put solar panels on my home one day.
Q:solar panel for pool pump?
Why don't you use the mains as the battery with net metering. That way you don't have to have two pumps, a DC pump for the solar and an AC pump for the mains. A 230 V, 6 A pump draws 3.68 kw. A typical solar panel produces about 400 watts so you would need about 0 solar panels which should run you about $20,000 US. Of course, you may not need to run the pump continuously but in order to use fewer solar panels for sporadic use, you would need the batteries or the net metering. Keep in mind that with the costs of the panels, you will be paying about 38 cents a kwh. Grid power usually costs around 5 cents a kwh.
Q:Joule Thief vs Solar Panel?
Solar panels convert light energy to electrical energy with an efficiency of around 5%. A SMALL solar panel will only produce a small amount of power (watts) your joule thief circuit wont help because as you draw more current from the solar panel the voltage will drop; and your joule thief circuit just reduces the efficiency of the whole system Try adding another solar cell in series to get more voltage and more power.
Q:Are solar panels actually efficient?
There is not a yes or no answer. But for the majority of the population it is a definite no. Because the energy needed to make a solar panel is more than the energy that a solar panel can return in its life time. so No for cities and urbanized areas because there is already existing infrastructure therefore you'll be wasting more energy getting them installed. And it is better and more efficient to have the more common energy sources for populated areas. However that being said it would be more efficient if you live in a remote area as it would not be worth it to build a huge electricity grid just to power one small house in the middle of no where.
Q:solar panel webcam?
Q:Solar panels for car fans?
The solar panel doesn't output enough power to run the fan directly, your best bet would be to just hook the fan back up to the battery, and then rig the solar panels up to help charge the battery and remove some of the load from the alternator. If you're trying to reduce your emissions/increase fuel economy then you'd be better of setting up a switch to disconnect your alternator when its not necessary to have it on. The alternator runs off a belt from the engine which requires some of the power output from the engine. Having this connected all the time increases the amount of gas used (marginally) but you'd be saving more gas doing that and using the solar panels to keep the battery topped up.
Q:Why did the voltage of a solar panel drop significantly after putting it through a step down voltage regulator?
you cannot treat the open circuit voltage of a solar panel like a voltage source (like a battery.) the load response of the panel doesn't behave that way. small panels and panels that are producing less than about .5A are very happy to have their output voltage pulled down to whatever they're connected to (typically zero.) I observed the same phenomenon when i connected a 2V 725mA panel to a 2V 325mA fan -- the open circuit voltage of 5V dropped to 3V when connected to the fan, and returned to 5V when disconnected. The easiest workaround is to use 2V of rechargable batteries in parallel with the panel so that the battery holds the 2V potential difference and the panel just supplies the current. any excess current charges the batteries, so you might consider whether or not you need some type of charge controller to prevent burning the batteries via overcharging. there are actually very few applications of solar panels connected directly to circuits that i have seen that have any kind of robust performance -- if they work at all, they eventually die/burn themselves out in a couple of months. the best robust designs always have a rechargable battery and charge controller somewhere in the power circuitry to buffer the load circuit from the panel. .
