Q:I'm a student trying to design a mounting structure for solar panels. I'm reading about passive trackers so as to track the sun for optimal energy production; but I am not fully quot;seeinghow it works. Can someone please help explain it to me, or at least send me a link(s) that could help explain it well?THANKS IN ADVANCED!! [and HAPPY HALLOWEEN!!]

It appears to be relying upon a phase change of liquid to gas to liquid to balance the system and return it to the east in the morning.

Q:Is it really necessary to make solar panels that expensive?

Q:Solar panel packages have different levels of power. For instance you can get a kw system but is this kw per hour or day. How does this work?

kW is the unit of measurement used. kWh means you have kW steady for an entire hour. In the case of solar panels, say you are using 00W panels. That means at any given time assuming ample sunlight is hitting the panel, it is producing 00W. You wanted a kW so you will need ten panels at 00W (less or more depending on the rating of the panel) this will give you kW. That means at any given time you can get as many watts as needed up to kW (000W). Say the sun hits the panels for eight hours a day, you will have kWh each of those eight hours, or 8kWh per day. Unless you have a system of batteries to capture unused power, you will only be able to use up to kW (000W) at any given time, any unused power will be wasted. Solar panels alone are not like a generator, they do not slow down or speed up depending on demand. Even with no load on them, they will produce as much power as they are able, and without batteries that power is lost. To simply answer your question, if you get a kW system, that means kW per hour.

Q:Photosynthesis is fairly inefficient, but efficient enough to power all life on earth.

One of the primary reasons solar cells are made of silicon is that the bandgap energy of silicon happens to be nearly equal to the energy of visible light, which is the major portion of energy emitted by the sun. Therefore, silicon is the ideal substance to fabricate solar cells with.

Q:Can solar panels be installed in a community or neighborhood?

Yes, solar panels can be installed in a community or neighborhood. In fact, many communities and neighborhoods have embraced solar energy and installed solar panels on residential and commercial buildings. Installing solar panels in a community or neighborhood can contribute to a cleaner environment, reduce energy costs, and promote sustainable living. Additionally, community solar initiatives allow multiple households to collectively benefit from shared solar installations, making it accessible to a wider range of residents.

Q:How much energy can a solar panel produce?

The amount of energy a solar panel can produce depends on various factors such as its size, efficiency, location, and the amount of sunlight it receives. On average, a typical solar panel can generate between 250 to 400 watts of power per hour.

Q:I need a solar panel which can light up 4 full loaded 5 rooms appartment houses

good idea going solar, i would suggest doing a google search, as their are many suppliers. then you need to calculate the amount of wattage you think these apartment houses are going to require. volts x amps = watts. if you are going to be off of the power grid, then you will need a way to store excess energy during good times,( lots of sun) in order to use it during bad times ( no sun ). or see if you are able to sell your extra power back to your local power company, check because some companies do not allow this. you could even have a generator for emergencies if you go off the power grid. on final note, solar is a pretty sizable investment up front and your profits are seen mainly in the long run, but you will get energy savings immediately, but more likely those savings will go to paying off the solar panels also, you will need a converter to convert the ac (alternate current) produced by the panels into dc ( direct current ) which is used by the apartments. it will tie in to the existing electrical system in the apartments. i know germany is really pushing solar energy and they offer their citizens some pretty sweet deals to go solar. the companies are profiting from this so i would suggest looking for a supplier in germany, first. they may have better deals, or try bp (british petroeum) they have been in the solar business for awhile. i wish you success!

Q:i am doing this group project fro school. I would like to know if anybody knows anything about how to read a Spec. Sheet on Solar panels and where I could go to start researching them. Anything would be great!

Rate ,power , voltage and effencicney are four important iterms to choose one battery.

Q:Do I need some type of regulator when the batteries are fully charged.?? The Arco Panels voltage is approx 7VDC at 2.5 amps, Should I limited the voltage to 4VDC???. I would like to connect both panels to up to five batteries at one time...???

You can buy Solar Charger Regulators. I don't. These chargers limit the charging current to the batteries, so you do not get a full efficiency of the solar panel. They disconnect the batteries from the user side (the bulbs you use) if the battery voltage goes below a certain level (i.e. below 8V for a 2V battery), so you cannot use all the power available in the batteries, even in emergency. They introduce, at least, a 0.7V loss (diode forward voltage) between the panel and the battery. If you have SEVERAL panels and a lot of batteries, use a controller as above. If you only have one panel, insert a 5A trip fuse in line (in your case: twice the current of the panel), and a 0-20A diode in series between the panel and the batteries (Kathode side of the + of the battery, Anode side of the + of the panel). Install a voltmeter across the battery. The fuse will prevent any short or over-charge current. The diode will prevent the battery to discharge into the panel at night if it is not already protected. The voltmeter will allow you to watch the status. Your thought of limiting the voltage is useless: should the battery be low, the panel will drop its voltage, limited by the max current. Should the battery be fully charged and the solar panel at full efficiency, it will just try to charge the battery more. A bit of bubbles may result, hence the voltmeter to watch over it. If you want to limit the voltage to 4V, put a 4V Zener (4Vx2.5W!) in series with a resistor of, say, 7V-4V/2.5A or ~ Ohm, 5W, in parallel with the panel.

Q:Can solar panels generate electricity during a blackout?

No, solar panels cannot generate electricity during a blackout. This is because most solar panel systems are grid-tied and rely on the electricity from the power grid to function. When there is a blackout, the grid-tied solar panels automatically shut off to prevent any electricity from flowing back into the grid, in order to protect utility workers who may be repairing the power lines. However, it is possible to have a backup battery system installed along with the solar panels, which can store excess energy and provide electricity during a blackout.
