- Q: I'm curious to know if the small solar panels on a calculator (ie TI-32) could produce a voltage similar to what is used in a single-use (disposable) camera, approximately 4V.
- It isn't Volts that matter if you're trying to put the calculator solar panel on the camera. It would be the amps. The calculator's solar panel will put out however many volts or very close to what the battery puts out. If you want you can test it out with a Volt/Ammeter. You see, those cameras use 2 double A batteries. They are going to put out a higher current than the small dime shaped battery in the back of your calculator; a higher voltage perhaps too. Those disposable cameras have a photo flash capacitor in them that has to charge. You can hear them charge up when you tell it to turn on the camera's flash. Sounds like a winding then the little orange light comes on. That light means the capacitor is charged. You SHOULDN'T be able to change out the batteries in the camera with a solar panel from a calculator without having to wait days for that flash capacitor to charge. Sorry. EDIT: HOWEVER, you can take multiple solar panels and wire them in a parallel circuit to get more current(amperes) or wire them in a series circuit to get a higher voltage. If you were to do this you could power whatever you wanted with them. Even your house if you were to get a rectifier to convert the power from DC to AC.
- Q: And I'm tring to decide if I should buy it. Let's say my house would need Megawatt per hour. That's 000 megawatts per hour. This solar panel produces 36 watts. I don't know how if that means per hour or what???
- There is no such thing as a megawatt per hour. Watts aren't a unit of energy, watts are a unit of power. Power is the rate at which energy is converted. Power is to energy as speed is to distance. Watt-hours or the famous kiloWatt-hour are units of energy. Also the Joule is the more scientific unit of energy.
- Q: Can any body tell me how much Electricity can 0 Standard solar panels produce in a day( in terms of Watts)Or else please tell me how many Watts is 5 volts of electricity?
- You have to know the amperage to figure out the watts. Volts x Amps= watts
- Q: They have been around long enough to be cheaper. Unless they are made out of a natural material that is rare and hard to find, there is no reason why they should be so expensive. On another note, I think that all low power devices like cell phones and even laptops should have solar panels. Even if it is not enough to fully power the device for a long period of time, it will provide some electricity savings and with millions of people saving a little power adds up.
- Because most solar cells are made from silicon crystals that is grown very slowly. Growing silicon crystals from pure silicon is an extremely slow and expensive process.
- Q: I am interested in solar energy, but am not sure how eficiant it would be in the northwest? Any comments would be apriciated.
- The solar rating of your area is Good so I wouldnt see the reason not to use it. In my area solar rating is very good I get all evergy from it plus even selling it. My payback time was very quick but... If you are not in a hurry or cant afford to spend a lot, wait till end of the next year when the new flexible panels are coming to the market. They are suppose to be a lot cheaper, enviromental friendly more effective than the ones on the market now. Check out MY Estimator. I think for USA users its the best help on the net. You'll see your costs, tax incentives can get info about local PRO's aswell. Often people are shy to ask quotes but solar is overpriced at the moment so spend your time finding the best deals. Also check where panels are made, their efficency; warranty is usually 20 to 25years. Surf the net- OKorder, OKorder then check companies who sell solar panels. Some even offer price fix if you see other place selling with better price. Good luck!
- Q: how does solar panels work?
- Solar panels collect solar radiation from the sun and actively convert that energy to electricity. Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy. The energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current, from which metal contacts in the solar cell can generate electricity. The more solar cells in a solar panel and the higher the quality of the solar cells, the more total electrical output the solar panel can produce. The conversion of sunlight to usable electrical energy has been dubbed the Photovoltaic Effect. The photovoltaic effect arises from the properties of the p-n junction diode, as such there are no moving parts in a solar panel.
- Q: i want to charge my mytouch 3g with solar panel(s) it has a 500mah 3.7v 4.4wh batterieswhat do i need to charge it can i use RadioShack 0.5W Solar Panel 4.5V or RadioShack? W Solar Panel 4.5V
- see u have to make ur own ckt for this ur solar panel generate DC if u want to charge ur phine then its convenient way to harge with ur charger for this do this search for net to convert DC-AC convertor since ur charger work on AC so when ur solar panel generate DC it convert into AC that will charge ur phone in ckt u need this thing filter and amp ie the DC voltage come from solar panel 2 DC to AC convertor 3 AMP for AC 4 filter for AC and u are done....... fine ckt from google.....
- Q: Can solar panels be installed on a commercial building?
- Yes, solar panels can be installed on a commercial building. In fact, many businesses and organizations are increasingly adopting solar energy to reduce their carbon footprint and save on energy costs. Installing solar panels on commercial buildings can help generate clean, renewable energy and contribute to a more sustainable future.
- Q: trees vs solar panels who would win?
- Trees for sure. Their already plotting the overthrow of humans.
- Q: How much electricity can a solar panel generate?
- The amount of electricity a solar panel can generate depends on several factors such as the size and efficiency of the panel, the amount of sunlight it receives, and any shading or obstructions. On average, a typical solar panel can generate between 250 to 400 watts of electricity per hour.
