Q:when building a solar panel should the diode be on the positive or negative side?
Bypass diodes would be in parallel with groups of solar cells in a panel. For example, if a module has 72 cells, maybe every 8 cells, there will be a bypass diode. A bypass diode does nothing except salvage some of the energy from the panel if some of the cells are shaded, and others are not. Or, if you have multiple panels in a series string, the bypass diodes allow the other panels in a string to continue to contribute energy when one panel is shaded. Unless you're forced to put the panel(s) where there will be shade during the day, the bypass diode does not matter. Commercial panels all include bypass diodes. Blocking diodes are generally NOT included on commercial panels. If you're going to a grid-tied inverter, you probably don't need one. There are stringent regulations on how panels must be grounded, and whichever side of the panel is grounded should not have a blocking diode. NEC regulations call for a continuous ground to earth. For example, if you have negative ground on your system, the blocking diodes, if any, should go on the positive terminal of the panel. By the way, if you're in the US or Canada, do understand that a home-built panel will not be legal to connect to a grid-tied system. And a grid-tied inverter that plugs into the wall will also be illegal. I'm only saying this because I don't want you to get hurt, or your house to burn down. Line power is nothing to be trifled with.
Q:How energy-productive are solar panels, compared to natural gas?
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:How much can I expect it to cost to install solar panels?
A solar system evolves many more components than just panels, and each with its own level of complexity and expense. Is electricity the only option for your consumption? I thought similarly yrs ago with my system, but now over the years the maintenance of panels, subpanels, charging systems, high effic batteries, etc has now proven to me that I should have ensured all other possible improvements be covered first to lower my overall uses.
Q:how to build solar panels?
At first, you will need about one square foot of thin copper plate, two alligator clips and short leads of wire, a wide mouth glass jar, tap water and salt. Cheers,
Q:DIY home solar panels?
Did . This will absolutely save yourself!
Q:Solar panel battery charging?
it depends how big the panel is. a small trickle charger (like a 2W panel with built-in diode), just connect + to + and - to - (parallel) to trickle charge the battery. The diode will keep the batter from discharging through the panel when there is insufficient sunlight. for a large panel (like a 220W 24v panel), you best go through a charge controller. the charge controller has 2 leads for the solar panel input, 2 leads for the battery connection and 2 leads for the 2v load. just follow the instructions to connect the panel and battery to the controller, and MAKE SURE YOU USE THE REQUIRED FUSES. very straightforward stuff -- just RTFM
Q:Can I power up 2Watt bulb using 2Watt solar panel power?
. Practically no. You have to account for startup current, and losses in the system. Ideally you would size your solar planel to provide the power you need to charge batteries in the day, for your needs at night. 2. Watts=Volts times Amps Really you just need to match the load and supply for volts, and make sure the supply has enough capacity to run your load. Current will take care of itself., in that the load will take what it needs to do its work. 3. It will bring the voltage down, causing the light to be dimmer.
Q:How can I regulate current from a solar panel?
Lithium batteries do have special charging requirements. I would recommend that you use the 2 volt charger that came with them to keep them happy. Automotive power systems can have voltages as high as 4.5 volts when the engine is running so there's no need to limit the output of the panel to anything less than that. Check with the charger manufacturer to see what it will withstand. Some will work with systems up to 24 volts nominal (up to 29 volts actual) found in larger commercial vehicles such as trucks and busses. If your charger will work with both 2 and 24 volt systems you might not need anything extra to use the unregulated output of the panel. Otherwise I'd recommend a shunt regulator to clamp the output of the panel to no more than 4.5 volts. That way it would dissipate (waste) very little of the panel's power, and even that would only be during those rare times when the panel is producing maximum output. Such a device could be as simple as a high power zener diode, a low power zener coupled with a power transistor, or a precision shunt regulator such as a TL43 coupled with a power transistor. A more complex way would be a to use buck/boost regulator between the panel and your charger. You might gain a slight advantage under low light conditions when the panel isn't putting out much but the overall efficiency could end up worse than the simpler shunt regulator. Under optimum conditions, I would expect it to take a full day for a 3 watt (peak) panel to charge just one of your 35 Wh batteries. Charging an intermediate device such as the Sherpa 50 through its built in charger and then using it to charge your battery through yet another charger would severely cut your overall efficiency. Depending on how long you'll be gone, it might be far more practical, reliable, and economical to just carry (or find a way to be resupplied with) a few additional fully charged 35 Wh batteries. Don
Q:Do solar panels add to global warming?
Solar energy is very inefficient, and so most of the sunlight that is absorbed by the solar cells is re-radiated back as heat. But that leads to a bigger point. Global warming is the ability, or inability of the Earth to radiate heat/light out past the atmosphere into space. Once the light reaches the surface and is absorbed, it doesn't matter whether it was by a black panel or a solar panel. Energy is energy. A black panel does not radiate energy into space, it emits it into the atmosphere. The use of electrical energy also generates heat which is transferred to the atmosphere sooner or later. The advertised culprit of global warming is atmospheric greenhouse gases like carbon dioxide, that reflect infrared wavelength energy from the surface back down to the surface. The heat generated by sunlight on a black panel, or from the use of electrical energy, is reflected back by the greenhouse gases instead of radiating out into space, no matter what the source. So no, solar panels do not contribute to global warning simply because of their transfer of light into electricity instead of infrared/heat. The source of the heat (black panel or electrical use) is not the (whole) problem. It is the greenhouse gases that trap the heat that is the problem, according to the global warming theory. I hope this helps.
