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. .
Q:Solar Panel HELP?
The only way it pays off is if your energy supplier or state refunds half or more of the cost. Even then, could take 20 years or more to pay off depending on your electrical usage. Most people are either misguided or doing it to reduce their carbon footprint.
Q:Can I join 5 or more solar panels into line to the battery bank. I don,t have a regulator connected, just st?
I am pretty darn sure you need the regulator because all the advertising says that you must have one if you have more than one small solar panel. I think you can overcharge your batteries otherwise. Solar power is still not cost effective, so most people have solar power because they care about the environment more than they care about expenses. If you are poor, it is better to skip solar power, unless you are in an area where there isn't access to electricity. For example, we have a cabin without electricity. I am a strong environmentalist, too. Solar power is too expensive still, for low income people. It is better to focus on energy conservation, imo. such as change your roof to white, to save on A/C, as the head of the US energy dept. says (he is a nobel prize winning physicist). PS Dave might be right on that stuff, i don't know. but all the ads say you need a regulator if you are going to have more than one solar panel so I assumed this was due to risk of overcharging.
Q:Best orientation for my solar panel?
Typically, solar panels are installed facing the same as your latitude = 2 degrees to the North measured from horizontal. 60 degrees from vertical = 30 degrees from horzontal will give almost as much power in June as in December = beginning of Summer. You can face your panels straight up = zero tilt from vertical = better for December/ not so good in June. Usually, the same tilt as your North facing roof is best as it simplifies installation and reduces wind loading. Shade from trees etc will much reduce the power you get. Neil
Q:how to design a solar panel to store energy and convert it into electrical energy?
image voltaic panels do no longer shop capability, they basically generate it. in case you opt to shop capability you like a battery economic enterprise of a few sort to get you for the time of the night and each time the sunlight isn't shining. in case you have somewhat extra in the fee selection you would be able to desire to look at a geothermal equipment to your place's heating and cooling needs. they are distinctly useful structures and you'd be able to supplement notwithstanding you like. notwithstanding you do, in spite of the indisputable fact that i'm hoping you have a sturdy construction envelope in place already. image voltaic panels are cool, yet once you have a leaky homestead, you're nevertheless no longer getting the final out of your panels. Do the extra mundane stuff first. Insulation, homestead windows, and climate-tight doorways.
Q:Solar panel trouble?
To test a solar panel, connect a voltmeter, and turn on and off a light. If the voltage increases when the light above the panel is on, it is working. The solar panel does convert solar (light) energy into usable (electrical) energy. No extra conversion is necessary to make eletricity. You might, however, want to convert .5 VDC or 2 VDC output of solar panel(s) - or the batteries they charge - to 20 VAC with an inverter though. If a capacitor is broken, it will look like an electrical short circuit all the time.
Q:2- 390 W Solar Panel's Series or Parallel?
Q:What is the best low power alternative for TV set, to use as screen for dvd player, with a 30watt solar panel?
Do what we do when power is cut (although we have very reliable power - we loose as much as 2 hours a year), is go Amish. That is go without powered technology. Now, for you, you need more than a solar panel (and likely more than 30W, but that is a start) - you need a battery or set of batteries to store the collected power. 20Ah might do. You need an inverter to power things. For that, likely a 300W will do. For a TV, go shopping, and look at the labels on the back of the TVs. I just bought a 24 TV rated at 40W. If you get a 9 LED TV, it may be likely you can run that directly from battery, for many have separate DC brick supplies. With those, you can make a cable to power it directly from a 2V or so battery, if the supply can make 2 to 5V. Depending on your provider, you may be able to get a mini-decoder which uses a separate brick or wall supply, which means the decoder likely can be directly battery powered. Such a decoder may draw less than 20W.
Q:Why won't my solar panels drive a motor?
to do basic electrical experiments with solar panels and motors, it is necessary to have a digital volt-amp-ohm meter sometimes called a DVM (digital volt meter). What is the voltage that the solar panels give when the motor is not connected? what is the voltage when the motor is connected? If the motor resistance is too low, then the solar panels will not be able to supply enough current to run the motor and the voltage with the motor attached will be very low. It might take a bright light on the solar panels or direct sunlight.
Q:I would like some info on Solar panels and Wind Generators...please?
Toronto would not be higth on my list of solar panel worthy locales. They are a bit pricey and are only cost effective in climates and locations with lots of direct sunlight. But if you could safely say you get direct light on your rood nearly every day, they could work. Wind turbines are getting better... especially omnidirectional dome type turbines. But again they are a bit costly, and work best if you believe you get direct wind for at least half the day. If your roof is reasonably flat and structurally sound, a solar hot water generator can be quite cost effective. Essentially it is a panel of corrugated metal under two thin transparencies of plastic. Water is pumped up to it and as it runs along the corrugation, the trapped heat under the plastic heats it up nicely. They are cheap to buy and easy to build and install, and will completely remove the need for a dedicated hot water heating system. Once again, it really depends on the precise location and construction of your house. Do a search for solar heat in your area. If it is cost effective, someone will be offering...
