Q:_How many solar panels needed to light up a whole house?
It's not really the solar panels that power the house, they charge a battery bank and there's an inverter that jumps the battery power up to household current level. If you start getting into more expensive systems, they can sense when the batteries are full and start diverting power into the local electric grid. Some places the electric company is required to pay you for generating current, other places tell you tough luck. I suggest looking on OKorder or something at some of the home solar kits on sale there and look at how large a house they are rated for to get an idea of how big a system you're going to need. I don't know if you have access to the power bill history of the house you're getting in Dubai, but the power company there might be able to provide you with a history of average kW hours the house consumes. A 2400 sqft house with a gas stove and a gas water heater and wood heat is going to consume far less electricity than a house with all electric appliances and the consumption history of an individual house should reflect that so you can buy appropriately.
Q:Solar Panel Charging?
you'll have to use 3 panels connected in series or use a dc to dc up converter, the former is a better option
Q:Solar Panels power help?
What you really need to calculate is your energy requirements, you are only stating your power requirements. Power (W) = how many watts of power are you using? Time (h) = how long are you going to use the power for? Energy requirement(Wh) = W * h take the answer to that equation and plug it into the exact same equation except substitute how much sunlight you get for h and then solve for W to find what you need in the way of a solar panel. Wattage of solar panel (W) = Energy requirement (Wh)/hour of sunlight per day (h) Now you know what wattage of solar panel you need. For the battery you use a different equation: Energy in the Battery(Wh) = Battery Voltage (V) * Current Capacity (Ah) Solving for Current Capacity: Ah = Wh / V This will tell you how big a battery you need, but you also need to be concerned about how much current it can source. For this you need to know what your peak power requirement is. Wmax = peak power requirement Max discharge current (Amax) = Wmax / Vmax Also you will need an inverter rated to Wmax as well.
Q:Silicon, Polychristaline, or Solar Panel?
Let’s start off and discuss the three main types of photovoltaic (PV) panels: Monocrystalline Solar Panels - Monocrystalline cells are cut from a block of silicon that has been grown from a single crystal.These tend to be the most efficient, but also the most expensive solar panels. They have been considered the go-to panels for the last couple decades, and also boast being the oldest and most dependable. Polycrystalline Solar Panels - Polycrystalline cells are cut from multifaceted silicon crystal. They don’t come from a single piece of silicon crystal, but rather from many different crystals. These solar panels tend to be less efficient than monocrystalline solar panels of the same size. This means a 200 Watt Monocrystalline panel will usually be smaller than a 200 Watt Polycrystalline panel. Thin Film or Amorphous Solar Panels - These panels are not made up of any crystals. They are actually a thin layer of silicon deposited on a substrate or base material like metal or glass. Thin film solar panels tend to be the least efficient per square foot, but they are also the cheapest. The best application for amorphous panels is if you have a large amount of surface area and space doesn’t matter.
Q:where could i buy a cheap and low cost solar panel regulator?
Solar cells shouldn't need a voltage regulator for simple projects like driving motors or powering CMOS electronic circuits. I would need to know a little more on your goals for the project to help. However, I will put a few links that may be helpful to solar cells and some voltage regulators. The first link is general solar cell info and includes manufacturer lists at the end. The second is a link to educational solar cell kits and cells that may be useful for you. The last one is Digi-Key which is good for finding components to make your own voltage regulator. Hope this helps with your project!!
Q:Are solar panels a good idea in Seattle Wa?
Are solar panels a good thing to do for the environment? - Yes. Can you recoup the cost your investment in the solar cells/panels in any reasonable amount of time in Seattle? - most likely - not. I know it's been a miserable spring in Seattle, but, I think we got 3 sunny days last month. With the number of cloudy/rainy days here, solar will only really benefit you in June, July, August and September. There are two kinds of solar panels - electric or water based. The electrics - photovoltaics - are costly to purchase and it's difficult to store the electricity once you make it. A water heater type solar panel initially cost less and can provide some benefit even on partly cloudy days. I have even seen instructions on how to build your own (if you are frugal and handy) I just do not think it's worthwhile in Seattle - if it was Denver or Phoenix we were talking about - then it would be a different story.
Q:How to hook up a Solar Panel To a single outlet?
That panel you reference puts out about 20W. @ 8V of DC. You can't wire that to a standard 20V outlet without a battery/inverter unit. Even then, you don't get a useful amount of power. In a full day you would collect enough energy to run a small TV for about an hour.
Q:how do solar photovoltaic panels work?
Hey E Girl, photovoltiac panels are pretty simple. They start with a solid block of silicone, and shave thin layers off of them, called wafers. Once you have about 72 of them, you take half of them and dope them with boron, then the other half are doped with phosphorous. Once that's done, they take one each phosphorous and boron wafer, and glue them together with a special conductive epoxy glue, and attach a wire to each wafer. When the two glued wafers are exposed to the sun, a reaction occurs that forces free electrons from the silicone particles from one wafer onto the other, and a voltage is generated between them, about /2 volt to be exact. Once all 36 pairs are glued together, they are wired in series, connecting the phosphourous wafer from one to the boron wafer on the next, and so on. If you start with 72 wafers, you'll have 36 pairs glued together when you are done. At /2 volt each, that makes a 8 volt panel, which is used to charge a 2 volt battery. The charging source always has to have a few more volts than the battery. These 36 pairs of cells are then arranged on some kind of back board, glued down, covered with acrylic glass and mounted in a frame. There are some great websites you can go to for more info, I will list some below. Did you know that there are over 00,000 homes and businesses in the US alone that use some level of solar power to operate their electrical systems? That's good news. We actually live in one of those homes, it is powered by both the wind and sun and heated with solar and wood. I hope this answers your question, good luck, and take care, Rudydoo

Q:Questions about charging batteries via solar panel...?
Yes, you have it right you need two 2V panels wired in series to give 24V to charge a 24 volt system. But along with the 24V you also want some amperage, otherwise it takes forever to charge. Most of the little chargers are called trickle charges because they only have an amp or two. If you had two 25 watt solar panels putting out 24V you have : watts = volts * amps 50 watt = 24V * x amps x = 2 amps If your battery is say 50 amp hours of storage, then if you are putting in 2 amps it will take you 25 hours of sunlight to power it back up from a dead battery. So the charge time depends on how many amps you are putting in there at 24V A car battery charger typically charges at 0 amps at 2V, so 2 * 0 = 20 watts of power going in there So if you go solar make sure to use a charge controller and a big enough panel to get close to 00 watts for any decent recharge time. The charge controller makes sure that the battery only gets voltage going one way and it least 24V. So if the sun went behind some clouds and the voltage dropped to 20V, the controller shuts off the current until the voltage equals 24V or more
