Q:Will a 2W, 2V mono solar panel power up a laptop battery?
I'm afraid neither of these panels will do much for charging or running your laptop. If the power brick is supposed to emit 5 volts at 5 amps, that's 75 watts. Neither of those panels provides enough voltage and the power output is obviously far too small. The capabilities of solar power are vastly overestimated for small panels. Sunlight is limited to about kilowatt per square meter under ideal conditions (summer time, clear blue sky, for a few hours around noon in the US southwest). But consumer panels top out at about 5% efficiency, so your limit is 50 watts per square meter - in other words you would need about half a square meter, or about six square feet, of panel to provide 75 watts. And even under ideal conditions you will only get that much for a few hours each day. Also, the panel's voltage output is not regulated, so even if you find a panel that emits 5 volts (this would actually have to be made up of groups of 30 cells in series, as they emit half a volt each at most) you can't just connect the panel output into your laptop's DC in. You'd need a regulated DC-to-DC supply, and since that is not 00% efficient it will cost a bit of the power... now you need even more panel area. All in all, not really a practical thing to carry along on a camping trip.
Q:How do Solar Panels Work?
A solar panel is a panel of a certain material that is very sensitive to light. Now, when you place if out in the sunlight, the photons enter that material, and gets converted to energy in the form of electrostatic electrons. These electrons gets carried away by the small silver wires you see running zig-zag over the panel, and is then used as electronic current. It is actually a lot more intricate and detailed than this, but this is more or less how it works. The reason is works better in sunlight, is simply because sunlight has a lot more energy behind it than lightbulbs and other sources, but they work as well!
Q:solar panel??????????????
The only real purpose of solar panels these days is to charge batteries - they just don't generate enough energy to do anything else and its dependent upon light levels - ergo you need the backup. Also - very expensive.
Q:How do you connect a solar panel to a motor from an RC car?
can increase your voltage from a single solar panel. In combination with a large capacitor, you could deliver short bursts of power to the motor which would allow intermittent operation.
Q:how to make your own solar panels?
Q:Do solar panels plug into an outlet?
Don is spot on. The connection of that thing called the grid-tie inverter is done at the service panel, the same box where your circuit breakers for the house are. It's not the kind of thing that most homeowners should do on their own.
Q:What specification of solar panel do I need?
You will need, A battery to store the electricity from the solar panel. The amount of electricity from the panel varies up and down as things such as clouds, position of the sun, etc. reduce the amount of solar rays hitting the panel. The battery stores it all, the ups and downs, and sends it back out at a steady voltage so you can operate your p.c. / appliance. A minimum of 45 watts solar panel. 60 watts would be preferable. 45 watts will charge a battery in one day under ideal conditions. You turn the panel as the sun moves across the sky, no clouds. 60 watts will charge a battery in one day with out moving and regardless of clouds. A controler to prevent the electricity from flowing backwards from the battery to the solar panel when the sun goes behind a cloud or sets at night and the charge drops below the voltage of the battery. A good controller will tell you the charge condition of your battery so you know when it is too low to operate your p.c. safely. And finally an inverter with True Sine Wave capability to change the electricity from the battery into usuable power for your PC and other electronics. Not all inverters produce true sine wave electricity. The electricity has static in it and will make your pc screen jump around and not function as it should. New digital T.V.'s also require true sine wave electricity to operate. Go the extra cost and get the inverter with true sine wave and be happy with the way your p.c. functions. Figure out how many Watts your p.c. or appliance will draw. and match the Inverter to the need. Do not go too big, as they cost more and consume more of your stored electricity to operate. Save as much electricity as you can. You will be able to operate your p.c. appliance longer. When not using your p.c., you can operate your T.V. or other low watt appliance.
Q:DIY home solar panels?
Not a good idea. The reason why panels are that much more expensive than cells is that the panels themselves are not that cheap either. If you start with the cells, you'll need - mechanical protection (hail, ice, snow) - electrical protection (i.e. waterproofing - if water comes in contact with the cells and wires, you'll get electrolysis which will corrode your wires and contacts faster than you can say 'b*mmer') - that setup will need to withstand temperatures between -20 and +30 °C (only guessing, might be worse) - oh, and the side facing the sun must be transparent (as far as possible) Now as to connecting the stuff: no, it will be neither easy to connect it to the house power nor to the grid - which is why that step (at least) in all countries I know of must be done by a certified electrician. If you get it wrong and you're lucky, only _your_ inverter will explode. Regarding the power: these 4W per cell (or kW for your shed) is the peak value, i.e. with the sun shining orthogonally onto the cells on a clear day. Since this (for a fixed installation) will only be true (at most) for a few minutes on a few days each year, your overall yield will be significantly less, probably more like 4 kWh/day for each clear day for each kWpeak you install _IF_ the shed roof is oriented exactly south and inclined towards the sun's noon position at the spring/autumn equinox (i.e. inclination angle = your geographical latitude). How many clear days do you have in britain? Yes, I had a similar idea for myself - but for one thing, the registered companies I addressed apparently weren't really interested in that small fry, plus the cost of the system + setup would barely have been amortized after the expected lifetime, even taking into account the (german) governmental subsidies. If I had the money to spare, I'd rather invest in a communal solar park. Much better ROI, the large installations get much better prices (per kW) for the setup.
Q:45 Watt Solar Panel Kit Harbor Freight?
Yes, 80 watts will be nearly twice as useful as 45 watts - but 80 is still a small number. Solar panel systems need an inverter and there's a slight energy loss at the inverter. And, if you want to use the day's energy at night, you'll need a battery or two. And every time you move energy into or out of a battery, you lose a little of the energy. All this is to say that you need to sum up the wattage of your appliances and add a fudge factor to accommodate for the losses. I looked at the kit and was moderately impressed. $200/45=$4.44/watt; that's a reasonable price but the links I left below talk of prices as low as $2.58/watt. Also the Harbor Freight kit doesn't contain an 'inverter' which you would have to buy. Also the wattage advertised for any solar panel assumes the thing is clean and pointed right at the sun on a clear day.
Q:I would like some info on Solar panels and Wind Generators...please?
You may have to put a snow roof over the wind generator to keep it working. A solar hot water system might be hard investment where you are but it could work if it's designed right. Check out the solar companies in your area for ideas.
