Q:are solar panels worth buying?
Depends where you live. Solar hot water is good for anywhere that doesn't get hard freezes, and will also work (slightly different technology) in colder areas, but will take longer to pay back. Hawaii probably has the best payback for solar water heaters of any state.
Q:what is the cost of a solar panel
I think Brian's answer was perfect for the US, but in the UK, with very high gas and oil prices, we would also look at hydrogen production from the wind turbine instead of a battery store, where excess capacity could be used to heat the house or potentially act as a car fuel. Alternatively we would look to selling back excess electricity to the grid.
Q:harbor freight solar panels ?
Actually, if you are looking to start slow and inexpensive, they are an economical way to get your feet wet, so to speak. I also tried the make them yourself kits, where you get a stack of cells, a frame and solder and you have to get the glass and assemble it yourself. I combined the Harbor Freight kit with one of those panels. Problems you will run into start with the kit having no inverter and not much information on any kind of power storage, you get to work that out for yourself. I initially wired them to provide all the power for the ceiling mounted lights in a small house, on a totally independent circuit, using 3 car batteries for storage. It worked perfectly, however the code inspector I got from the City could NOT fathom that my system had no connection whatsoever to his grid and would not pass it, even though I showed him the separate breaker box that was not supplied by the line coming into the house for the rest of the power. I finally gave up on him and put the lights back into the main system and use the solar setup to charge cell phones and occasionally power a lamp, as the inverter has plugs right on it. It keeps those car batteries fully charged going on 4 years now, with no issues detected at all.
Q:How do Solar Panels work, and how it can generate electricity?
Solar okorder.com under products that are sorted by watts per area. Also go to wikipedia to get more detailed information on solar cells.
Q:How does a solar panel charge controller work for batteries?
In digital circuitry almst anything is viable. Virtually. The changing of voltages and currents is most of the time viable however not constantly effective. Sure it is extremely easy to make use of the 24 volt energy panel to charge a 2V financial institution, offered that the 24 volt supply has the fundamental current potential to hande the load.
Q:How do solar panel power systems work?
Solar panel power system contains off-grid and on-grid types, for off-grid type: the panels convert solar energy into electric power and the power will be stored in batteries through controller at daytime, when the loads need power, the battery will charge them through controller; the on-grid system is almost the same, but without battery, it will connect with city grid.
Q:Why only Photo-Voltaic solar panels?
That sounds good to me. I'm all for any kind of new energy as long as it's renewable and doesn't pollute the environment. I'm even a fan of solar water heating.
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 regulator?
wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .
Q:Solar panel questions...?
. Do they scratch easily? No How do I remove snow from them without scratching them? Just wipe the snow off 2. What does the upkeep of many solar panels consist of? Clean them with tap water and paper towels once a month. 3. Are all solar panels made from the same material, regardless of size? Basically the same.
