Q:Solar Panel Voltage Question?
yes, i suggest u connect in parallel
Q:Which solar panel should I choose?
There is more to sizing a system than simply selecting panels. I would suggest that you contact a solar installer to do a bid on your system. The quote should be free, and you can always say no. If a house used 40 kWh per day in our area, that would suggest a 6 kW array to offset substantially all the energy usage over the course of a year. Serious panels tend to be in the neighborhood of 200 watts nowadays, and that would mean 30 of those. You could size the system smaller, of course, if you wanted to offset a smaller percentage of your electricity. If there is any way that you can reduce the energy requirments, that will save you more money than putting in big solar. For example, if you can cut that in half by adding insulation and more efficient appliances, you will save more money than if you got a big array to power everything as-is.
Q:The effect of colored light on a solar panel?
Likely there will be at least a small change in the no load volts. The short circuit current will be different and the watts output will be different. Connect an amp- meter to the panel with or without a to 00 ohm resistor in series with the amp-meter and you will see different amounts of current for different colors. You do however need to adjust for the amount of light falling on your solar panel. Possibly you can use a exposure meter or a bolo meter as reference. Neil
Q:Solar panels don't work when it's too hot/sunny?
So what do higher temperatures do to solar photovoltaic panels? As temperatures rise, the efficiency of solar panels decreases. Heat causes electrical resistance to the flow of electrons. On days where the temperature is more than 75 degrees, the electrical resistance makes the voltage fall thereby producing less kilowatts per hour. Your roof is much hotter than temperatures on the ground. That’s why solar panels are not mounted flat to a roof. There’s usually a few inches of spaces between the panels and roof so air flow can easily pass through and cool the panels down. There are some photovoltaic panels that are designed specifically to operate in hotter temperatures. These panels have a higher temperature coefficient. This is especially important in high heat climates like Arizona or New Mexico, but probably wouldn’t make too much of a difference in New England (except maybe this year). If you do live in one of these areas, you should speak to your solar installer to make sure they are using they right equipment for your region. Please note: Solar thermal panels used to heat water can withstand high temperatures without any degradation. In fact, hotter temperatures would actually be better for these types of modules.
Q:Solar Panel Efficiency?
When it exposed to light, it starts generate electricity. Now the 200W written on panel is not its all time power. Its Watt Peak (200Wp) , it means when sun is at peak. it is around PM - 3.30PM daily in India(plane area). And panel never give 200w for more than 5 years, the efficiency reduced up to 0% at completion of 5 years of panel and 20% up to 25 years of life of panel.
Q:Need some Information about solar panels ?
No. The only coatings I am aware of are those that reduce reflection so more light gets through the protective surface to the actual cells. Anything thing that affects appearance is going to be reflecting light back to the viewer and the photons of that light are not available for electricity or heat. If the appearance of the panels offends you, then they need to be concealed by a fence of panels around them that do not throw shadows on the panels.
Q:How much electricity does a solar panel generate?
This question was answered a few days ago. The Watt is the unit of of power, not the unit of energy. Energy is measured in Watt-Hours or Joules but not in Watts per unit time --- see the difference --- [] a Watt per hour v. [2] a Watt for an hour? The term, Watt per hour does not make any sense --- it is a bit like saying my car has 00 Horse Power per mile. You are right to say that the round figure for the power input of a solar panel is ,000 Watts per square metre, in the middle of the day when the sky is clear. Were the sun to shine for 0 hours per day in the summer, you could get as much as 7kWatt-Hours per day --- if you were very lucky. The roof area of a small house is no less then 50 square metres and this is more than big enough to supply all of you household energy needs but taking account of rainy days and taking account of the need to store the energy for night-time is an expensive problem, to satisfactorily overcome.
Q:Solar Panel Question...?
Nice enough idea you have there, but practical reality is waiting to bring you back to your senses. The appliances you want to operate take a lot of power. You would need an awful lot of solar cells or a very cumbersome windmill to provide sufficient energy for them. You will find that for a mobile kitchen, an ordinary generator running on gasoline or diesel will be much less expensive to buy and maintain, less trouble to haul around, and much easier to replace if necessary. Considering that propane will probably prove less expensive yet, go with that for as many appliances as possible.
Q:Solar panels single crystal and double crystal in the rain which is easy to use
From the cost of production, than the monocrystalline silicon solar cells to be cheaper, easy to manufacture materials, saving power consumption, the total cost of production is low, so get a lot of development. In addition, the polysilicon solar cell life than monocrystalline silicon solar cells shorter. From the performance and price ratio, monocrystalline silicon solar cells also slightly better.
Q:Can you make a Solar Panel Heater?
Short answer is yes. Good to start out a large tank, or big rock to mount your collectors on. Something the stock won't eat or push over. I would start with a swimming pool solar collector. It is just a big piece of black plastic aimed at the winter sun. A collector with insulation and covers will give more heat per sq foot and cost more. Big mirrors and a black painted stock tank might be enough. Insulation of the tank might help a lot. Is the water liquid when pumped up the tank? Do you truck the water in? Is there any electric power wired there or near by? Electric solar collectors can pump and heat water and charge batteries, but it is also possible to circulate water using a thermosyphon set up. You don't have to use photocells. If it gets cold enough some collectors can freeze solid and damage themselves. There are collectors that contain two loops one water the other antifreeze.
