Poly Solar Panel Description

Photovoltaic modules (also called solar panels) are the core part of solar power systems, as well as the most important part of the solar system. Its role is to convert solar energy into electric energy, and sent to stored in batteries, or promote work load.

However, with the use of micro inverter, can be directly convert the current source of pv modules become approximately 40 v voltage source, can drive electrical application in our life.

Q:What SOLAR PANEL kit do I need?
I okorder.com
Q:Will my 8watt solar panel charge a car battery and how fast?
8w will be .5 amps or so.That would charge a .5 amp battery in an hour.scale that up to whatever your battery amp-age is and you will have an idea.But given that car power is upwards of 40 amp/hour,your looking at 60 hours+ for a full charge on small battery.I run a 400w inverter for emergency lights and tv (get the occasional power cuts)from an old truck battery with big amps and charge it with an optimate,but in doing so I found that I had to run a amp check on power draw to find the lowest use lights.and tv,Some of the so called low power consumption compact fluorecents had widely variable draws,after testing one was found that drew .68 amp and I chose the lowest mesured tv amperage draw.not exactly an answer to your qu,but end use is the same.Running the lamp only I eventually gave up checking on the drain after about 30 hours and now just periodicaly charge the battery.Rounding off.tv draw maybe 3 amps for a small set and watched for say 6 hours would be 8 amps drawn.that would need -2 hours on your proposed set up in ideal conditions.I have kept the figures rough because there is always losses in any system .so it comes down to how much tv you watch and how much the sun shines
Q:What is the difference between Photovoltaic Panels and Solar Panels?
Both of them are different types of solar panel. EDIT: Misspelling on Jeff's answer below! I think he means 'silicon,' not 'silicone!' Solar cells are typically grown on a glass substrate or put onto glass. Silicon is currently the most common material, followed by CdTe or cadmium telluride. Other materials like CIGS (Copper Indium Gallium (di)Selenide) are breaking into the market. Some people have great hopes for organic or 'dye' solar cells.
Q:do solar panels have to be in direct sunlight?
As above, but also make sure the panels you use will still produce if partially shaded. Some older panels will quit producing if you so much as put your hand over a small portion of it. Newer ones don't do this but are more expensive. As you may need more panel area to produce enough energy to fill a battery (if that is how you go) make sure you have the room/roof area for additional panels.
Q:Can you make a solar panel shift sideways?
having solar panels move like that on a mobile platform is inadvisable -- especially if there is a dynamic wind load resulting from the motion of the mobile platform. Even having a tilt mechanism is dubious at best. think of what limited marginal gain would be gained by mounting a small solar panel on the moon roof of a car. (ultimately, the best answer is to turn the car so that it's angle to the sun is optimal -- but the road/travel direction constraints are what ultimately prohibit that.) while there are ways to build sliding panels, the weight constraints would interfere with your weight/thrust ratios to the point of futility. if you really need that panel somewhere else, don't slide it out of the way, just buy another panel and mount it there. it's more expensive, but it's actually the cheapest solution in terms of design on a mobile platform.
Q:How to build a solar panel for lighting/heat source?

Q:Why are solar panels not that efficient?
The latter link has a decent explanation, if not a bit technical: One of the most fundamental limitations on solar cell efficiency is the band gap of the semiconductor from which the cell is made. In a photovoltaic cell, negatively doped (n-type) material, with extra electrons in its otherwise empty conduction band, makes a junction with positively doped (p-type) material, with extra holes in the band otherwise filled with valence electrons.
Q:How many solar panels?
A laptop is about 70 to 00 W, and you have two. You also may need to power a router, and modem. So, about 50W to 250W contineous should cover it. To save power when not in use, you can let the display go blank. This will reduce your solar pannel, and battery size, and cost. You will need batteries, and blocking rectifier to store the energy for use at night, and a 300W to 400W inverter. Checkout the link below for purchasing solar equipment. You can only hope to get about 8 to 9 hours of full output from your solar pannels, and 80% efficiency. The laptops will be on and using about 200W for the 8 hours during the charging period. So your pannels, need to produce that plus 2 times more than this amount, so you can charge the batteries for the evening, at the same time. So for 24 hour operation, you will need 200W x8hrs for the laptops, plus (6 hours*70W)/8=340W avg. Total of ~540W for 8 hours. Assuming you use power saving modes when not in use, you can probably get away with 3x60W -- 520W to 600W pannel. ( Thuja is right, a few cloudy days may knock you offline) Batteries. A common low cost ( $40) automotive battery can hold about 40 Amp/hours at 2V. Under load, you may get 35 Amp hours at 0V, which is about 350Watts for one hour. You need about 80W avg for 6 hours, or ~ 2900Watt Hours. Which means you would need 9 automotive batteries. Deep storage batteries cost more, but are more durable. 6*00W pannels, $460*6 ~ $2800 Inverter $70 Batteries $400 Battery cables, rectifier, lugs, connectors $50 There are probably some other hidden costs. I was rooting for you, but it appears to be pricey. Another thing you can do, is to use the new energy efficient RF florescent bulbs for lighting. The color and brightness are excellent, and a 60W bulb only uses about 3W, and they last a lot longer as well.
Q:Will a 3w Solar Panel Charge A 55ah Car Battery?
Quite a while. I am assuming you are using 2 volts as your buss power. The small panels were intended as a float charge for batteries to keep them from discharging over a period of time. 3 Watts means only /4 Amp. Normally when I do slow charging of batteries, I am using right around amp, and that takes about a week to bring up a battery that was discharged past 80 percent capacity. When you factor in losses from corrosion, battery self discharge, and loose connections, you will likely want to add more panels. using your 55Amp/hour battery, a amp charger running constant in a perfect world would take 55 hours. Real world, probably closer to 64 to 72 hours. That for simplicity is 5 Watts constant charge power. Now you are using /5 of that with your current setup. so 5 times longer, whichh puts you in the 300 hour range of real world, or 220 hours of perfect world. This time of year, you may have about 8 hours worth of charging light, which puts you at close to a month. Don't fret. If you are using it for lighting in a shed, Power LEDs and tethering some of the inexpensive LED lights to the 2 volt source will give you plenty of light for a very long time, the panels will help some, but you will likely need to put the batteries on a charger, or you can build a gas powered 2 volt generator easily enough. Charge it up only when needed.
Q:2 Questions on Solar Panels?
The available energy is a function of several factors including insolation (sunpower) mounting angle, gathering area, type of cell and conversion efficiency.
