How much solar panel surface area is required to generate 1500kW at a panel efficiency of 30 percent?
You can size your solar array in just two easy steps! (Well, okay, there's a little research involved, too.) To estimate the size of your solar array, you'll need to know: # The number of Watt-hours (Wh) you plan to produce in one day. # The insolation value at your location. I have found this website to offer the easiest way to find out How Many Solar Panels do you need in your Solar Array?

When installing surface mounted cable the best method of ensuring that it is kept straight is by?
When installing surface mounted cable the best method of ensuring that it is kept straight is by using more fasteners that is required by the electrical code. Another way is to install it into a conduit chase. The conduit can be fastened to the building using a level to keep it straight. The cable can then be pulled into the conduit.
What is surface leakage current?
Undesired current flow across the surface of a semiconductor device due to contamination of that surface. This disturbs the operation of the device and causes a variety of failures. Insulators can also have surface leakage current for similar reasons.
Why is stranded wire used?
Multiple stranded cable is used in transmission lines because the high voltage potential of each line causes the electrons to tend to run only on the surface of the line due to repulsion. You want to maximize the surface area of the line, hence the multiple stranded lines, so that you maximize the efficiency of the line. In fact, some transmission lines have a non-conductive core, adding strength while maintaining low weight.
What is an equipotential surface?
It's a surface over which electric charges are evenly distributed, caused by the mutual repulsion between charges of the same polarity.
What are surface temperatures of lepus star delta?
over 9000
How much surface area required to generate one ton of steam?
It depends on how long you are prepared to wait!
Why it is difficult to light a matchstick by striking it on a smooth surface?
A matchstick needs friction to ignite, which is provided by the rough striking surface on the matchbox or matchbook. A smooth surface lacks the abrasiveness required to generate the necessary heat to ignite the matchstick.
Was the purpose of the Intermodal Surface Transportation Efficiency Act?
ISTEA was created to generate as much as $90 billion in additional funds for new mass transit projects between 1992 and 1997.

Why doesnt mercury have an atmosphere?
One word- gravity. Mercury is just simply not massive enough to generate the gravity required to hold gases close enough to the surface to create an atmosphere.
Water cover of the earths surface 20 percent 30 percent 50 percent 70 percent?
Water covers about 70 percent of the Earth's surface.
How is condenser high efficiency obtained?
the high efficiency is obtained by using a larger condenser surface or by using more mordern alloys with more extended surface or fins
What percent of earth's surface is used for agriculture?
We use about 38 percent of Earth's land surface for agriculture.
What occupies 29 percent of the Earth's surface?
Landmasses occupy approximately 29 percent of the Earth's surface.
Why do shells have to be smooth On a wind turbine?
Shells on wind turbines are designed to be smooth to reduce aerodynamic drag and improve efficiency. A smooth surface helps to minimize turbulence, which allows the turbine to capture more wind energy and generate electricity more effectively. Rough surfaces create more drag and can reduce the efficiency of the turbine.
What percent of the earth's surface is water and what percent is land?
About 71 % of the surface is covered by water. The rest (29 %) is land.
What is the relationship between the efficiency of a heat exchanger and its surface area?
The efficiency of a heat exchanger is directly proportional to its surface area. This means that a larger surface area allows for more heat transfer, resulting in a more efficient heat exchanger.
