Why do you think the hubble telescope might need an extra solar panel?

so it can gather more energy off the sun and store it in the extra panels


Does solar energy create as much energy as coal?

"Create as much energy" is poorly defined. The amount of energy produced from solar energy will depend on the surface area used for solar panels, the weather, the efficiency of the panels, and for how long it is used. Similarly, the amount of energy produced by a coal power plant would depend on its size, its efficiency (which of course may also vary), and for how long it is used. Please think about what exactly you want to compare.


Will solar panels work on cloudy days?

As long as there is sunlight on the panels, the system will produce electricity. However, production will be less on cloudy days than on bright sunny days. Think of it in terms of visibility. There is still outdoor visibility on cloudy or rainy days, albeit less visibility. There is still production on cloudy days, albeit less production. Since there is no sunlight at night, there is no production at night.


What are the problems of solar energy?

There are several problems with solar energy. Most of these problems though are being solved. Solar energy has come a long way in just the last few years. 1. Cost - the single largest hurdle solar energy faces is that competing energy sources have always been cheaper in terms of dollars per kilowatt-hour (a standard measure). Compared to electricity from coal-fired power plants, solar is more expensive - if you don't consider the environmental costs (which typically are hard to asses a dollar amount to). But in recent years solar power is becoming closer and closer to grid-parity on price especially with the introduction of new types of solar panel chemistry like Cadmium telluride. 2. Site suitablity - many sites don't receive enough solar energy to make solar energy cost effective. Cloudy areas with frequent rain are often not as well suited for solar panels because typically solar panels need direct sun to produce the most power. That's changing though, new panels can now use diffuse light on cloudy days to still produce power. With prices going down steadily, more sites would be feasible that once were not. 3. Embodied energy - It takes a tremendous amount of energy to produce a solar panel. Because of this - depending on the type of panel and the way it was made - the panel itself may have required 11 years worth of its energy production just to make it. So if that's the case, the panel won't begin making 'new' energy until it has been operating for 11 years. It takes energy to make them, and you can think of this like taking out an 'energy loan' and so the loan must be paid back before an 'energy profit' can be made. Again, this is changing, new panels are made more efficiently, and require less material than older technologies so the 11 years is highly dependent on the type of panel and the manufacturing process. 4. Production and Demand - Typically solar panels produce the most energy during the middle of the day and somewhat less before and after than. Also, solar panels produce the most power during the summer. To the extent that demand for power does not coincide with this production curve, other sources of energy must be used to fill in, or some sort of storage (like batteries) is needed. 5. Materials - The material used to make solar panels is in short supply or the supply has fluctuated. This, again, depends on the type of panel, some panels don't have this problem. Shortages in materials mean it can be hard for producers to meet demand - thus pushing up the cost - which is the main stumbling block for the adoption of solar energy.

i think two.


How big are solar panels on houses?

It really depends on the type of house and amount of solar cells. But they are usually large solar panels. People would think of big solar panels as the ones on houses but you can get bigger ones but the ones on houses would be categorised as large/big.

what is the scientific name for the panel on a solar panel?

I think you are referring to the term "photovoltaic" as it is applied to solar panels. Sometimes it is abbreviated as PV panel.


What are the disadvantages of solar resources?

The sun isn't constantly out so solar panels can only collect energy during the day. Also, solar panels take up space and some people think they are ugly. Personally, I think that renewable and green energy recources such as solar, wind, and hydroelectric power are the way to go. They don't hurt the environment and the are easy to obtain!

What is the solar panels power?

The most powerful solar panel is the Sunpower Turnkey Solar Solution. If you are thinking of getting this, think again. This effiecient Solar Panel is only built for busieness and Government buildings.


Tips on going green for buisnesses?

Recycle, get water generators and look into solar and wind electricity generators. You can do solar panels and wind turbines for less then you think.


Are scientist trying to find new uses of solar energy?

I think they are trying to develop better solar panels, and reducing their cost, but the use of solar energy in the future will still be to produce electricity


Why does a plant tilt its leaves upwards at noon time?

Plants are heliotropic, that is they have the ability to move in order to maximize the amount of solar radiation that they absorb - think of it as moving solar panels.
