Q:what do we mean by efficiency of a solar panel?
Photo-voltaic solar cells use the visible light range (photons) for the conversion of sun's rays to electrical energy. The potential of solar radiation is ,353 Watts per square meter, but that is mostly a measure of heat, or infrared radiation. The visible light is actually a small portion of the spectrum. You have struck on a problem associated with photo-voltaic cells. Infrared radiation acts to heat up p-v cells (heat stress), causing them to be much less efficient. It would be interesting to see a hybrid p-v panel that is cooled with fluid or air running through it. This would increase efficiency of the p-v process while providing a heating source. This in turn could be used directly for heating or for production of electricity through a generator system.
Q:Does a solar panel work on a cloudy day or a rainy day?
A PV array produces electricity whenever the sun shines on it. This is true from sunrise until sunset, and often times even after the sun sets! (A full moon on a clear night can actually produce small amounts of current from a PV system.) Generally speaking, an array will produce its maximum power between roughly 9:00am and 3:00pm.
Q:Solar Panel load resistors?

Q:How energy-productive are solar panels, compared to natural gas?
Natural gas is stored energy- once you use it up it's gone. Solar panels make energy for decades. Thin film solar is around 0% while crystalline silicone might be around 25%.
Q:Is getting solar panels worth it for your home?
It depends upon how you look at things. If you are looking for a decent return on investment, or a business decision, it is probably very unwise. In most cases people would see a far better return in upgrading insulation in ceilings, walls, and windows to much better insulation than they currently have, followed by proper resizing heating and air conditioning to smaller unit size to fit their lesser need as a result of the insulation. The heat an air conditioning units should be the highest efficiency available. The return on the above can make a positive and economic investment in many cases. If you have done the above first, and have money to spend and do not care about the return on it, then you can play with solar or wind. However, typical cost of generation of solar and wind energy is about $0.22 / KWH and you can purchase from utility at about $0.0/ KWH including generation and distribution so this is not all that prudent.
Q:What capacity solar panel do I need to charge batteries with a total capacity of 25,000 mAhours in 8 hours?
Each battery pack has the equivalent of only 2450mAh capacity at 4 volts, so for 4 battery packs like that, a total capacity of 9800mAh. Assuming that the solar batteries have no charge left after being on all night, and that day charging time equals night discharging time, the theoretical wattage would be 9800mA times 6 volts = 59 watts. Of course, battery charging is not 00% efficient, so you need more wattage than that. Plus, solar panels are rated at peak output at midday, while at other times of day their output is less than rated. And, the charging in parallel isn't a good idea, because real batteries have different internal resistances, some batteries would become overcharged, while other packs wouldn't get the charge they need.

Q:Do solar panels generate power when it's cloudy?
Yes. If there is any light, even on a cloudy day, a solar panel can generate power. But the amount of power generated is much less when the solar panel is not in direct sunlight (about 90% less). On a cloudy day, typical solar panels can produce 0-25% of their rated capacity. The exact amount will vary depending on the density of the clouds, and may also vary by the type of solar panel; some kinds of panels are better at receiving diffuse light. SunPower solar cells, for example, have been designed to capture a broader range of the solar spectrum. By capturing more red and blue wavelengths, their solar panels can generate more electricity even when it’s overcast. Ultraviolet light also reaches the earth’s surface in abundance during cloudy days (if you’ve ever been at the beach when it’s cloudy and gotten a sunburn, you’ve experienced this firsthand). Some solar cells are in development that can capture UV rays, although these are not out on the market yet. Even with a standard solar panel on a cloudy day, though, you will be able to generate some power when it’s daylight. The same thing is true in foggy weather. If you live in a city with frequent fog, like San Francisco, you’ll still be able to generate electricity when the fog rolls in. :)
Q:Help choosing solar panels?
Both might be bigger. When it is cloudy and little solar (iciness) you'll have a breeze. When it is nonetheless and sunny, you could have the solar. When the batteries are charged, extra vigour from the windmill can also be shunted right into a resistance heater in a water tank, preheating home water, decreasing that price. Downside of windmills: There is a few noise. you do desire a tower of a few form to get above treeline. It's mechanical, so it's going to want periodic renovation and would possibly holiday, or will put on out, or be broken in a windstorm. Panels will final for many years, simply have to be wiped clean of snow within the iciness, and washed off, in case you are living in a dusty subject. They are hard, however the glass can also be damaged.
