Q:Are there any disadvantages to using solar panels?

Yes, there are a few disadvantages to using solar panels. Firstly, the initial cost of installing solar panels can be quite high, although this cost has been decreasing in recent years. Additionally, the efficiency of solar panels can be affected by factors such as weather conditions and shading. Furthermore, solar panels require a significant amount of space for installation, which may not be feasible for everyone, especially in urban areas. Finally, solar panels are dependent on sunlight availability, making them less effective during cloudy or nighttime conditions.

Q:Has anyone had roof problems caused by rooftop solar panels?

Rooftop solar panels might cause all sorts of maintenance or poor installation problems but I rather doubt at this point if we can say that there is an issue with solar panels in general that will cause a problem with the roof. Rather solar panels tend to shade a roof on its most exposed side. Without solar panels southern facing roofs will wear out faster than northern facing roofs. Installed solar panels will tend to make the roof last longer.

Q:Can solar panels be used in areas with high levels of wildlife activity?

Yes, solar panels can be used in areas with high levels of wildlife activity. While it is important to consider the impact on local wildlife, there are measures that can be taken to mitigate any potential negative effects. Proper installation, such as elevation and orientation, can reduce the likelihood of wildlife interference. Additionally, using appropriate barriers or deterrents can help protect the solar panels and prevent damage from animals. Overall, with proper planning and precautions, solar panels can be successfully utilized in areas with high levels of wildlife activity.

Q:im trying to experiment with solar panels. so i dont want to buy a huge expensive solar panel if i dont need one.

Oh, i could hate that!! i'm continually having to locate a marvelous sufficient spot to apply my photograph voltaic calculator, very stressful. Dimly lit would not keep it going. i could somewhat have a reliable, rechargeable battery. Now, photograph voltaic backup may be high quality. you will desire to touch Nokia and tell them approximately it. possibly they're going to call the telephone once you!

Q:Can solar panels be installed on a government building?

Yes, solar panels can be installed on a government building. In fact, many government buildings have already implemented solar energy systems to reduce their carbon footprint and lower energy costs.

Q:Have a 20V 40W solar panel and it is attach to two backup batteries. Just want to know know how many watt of inverter do I need?

500 Watt Solar Panel

Q:wondering if i should get them?? not sure if its worth leasing? also anyone know anything about solar city?

They are absolutely worth it. I had a town house in Boston with solar panel shingles and they were able to supply enough energy for me to feed back the grid-- literally making money off of them. I am building a very large home in the suburbs now and we are doing solar shingles on that. Our contractor estimated that with our geotherm heat pump and energy efficient lighting we should still be able to throw back more energy to the grid all year round! As for leasing it is not worth it. For one thing, most leasing contracts prevent you from selling your energy to the grid yourself but rather they take a cut. But a bigger issue: the government gives you a tax credit on solar panel installations but only if you purchase them! I did the math myself the first time I did solar panels and with the tax credit I saved 25% over leasing. Something else to consider is that with your own panels you can connect a variety of other systems to your home and modify them as needed.

Q:During the summer my house uses about .47 kw/h I am wondering what solar panel do I need to cover most or all the electric bill. A link would be helpful too :)

The correct answer depends on how much total energy you use during the day and whether or not your utility allows something called net-metering. In net-metering, if you make more power during daylight hours than you consume, the meter goes backwards. Then at night the meter goes forward again. With net-metering you only pay for the difference.

Q:Can solar panels be installed on windows?

Yes, solar panels can be installed on windows. There are specially designed solar window panels available that can be installed on the glass surface of windows to harness solar energy. These panels are transparent and allow light to pass through while generating electricity from the sunlight.

Q:How could I find out what the amp output of a solar panel? Specifically, I want to know how many milliamps can the solar panel on a Casio fx-260 put out?

You need full sunshine from the sun, or a lamp that will give a light spectrum similar to the sun, a volt meter, Milli-amp meter, and a variable resistor of 0 to 000 ohms. The voltmeter test leads go across the solar cell leads. The amp meter leads will be in series with the solar cell. Let's say, positive lead of the solar cell to the the positive lead of the amp meter, the negative lead of the amp meter to one terminal of the variable resistor, and the wiper terminal of the variable resistor to the negative lead of the solar cell. Slowly decrease the value of the resistor until the voltage from the solar cell just begins to drop. Take note of the amp meter reading. This is about the high end range of the solar cell. You might want to begin with a micro-amp meter for the current meter.
