Solar Empire – Endless War

1.

   Out in space, one square meter directly facing the Sun would gather 1365 watts; down on the surface, after passing through the atmosphere, in the temperate zone you will seldom get more than about 1000.

   Solar cells have varying efficiencies, but seldom more than about 20%. So a 1 square meter panel would net you about 200 watts output.

   Since there are 746 watts per horsepower, 250 horsepower is 186,500 watts (746 x 250 = 186500) and at 200 watts per square meter, you would need 932.5 square meters (186500 / 200 = 932.5), which is 10,037 square feet. That’s the same as a square 100 feet on one side, which is maybe twice as large as the average American house.

   The typical automobile has about 10 to 15 square meters of upper surface area.

1. what are the benefits and problems about solar electricity?

   i got this project in science tats due tomorrow and i need it for that. There would be less global warming, obviously, and there will be more electricity because the sun is up for about 12 hours a day we would gain a various amount of electricity within the 12 hours....

2. How familiar are you with using solar electricity to power a residential house?

   I was wondering how much the average person knows about using the suns energy to power the average residential home... Do you know of any countries that already use the sun to power homes? please tell me where you are from as well please... thankyou! Hey 0077, to answer your primary question, I am quite familiar with solar power....

3. Converting sunlight to electricity with solar cells has an efficiency of 15%. It’s possible to achieve a highe?

   Converting sunlight to electricity with solar cells has an efficiency of 15%. It's possible to achieve a higher efficiency (though currently at higher cost) by using concentrated sunlight as the hot reservoir of a heat engine. Each dish in the figure concentrates sunlight on one side of a heat engine, producing a hot-reservoir temperature of...

4. What is Kenya’s feed in tariff price for solar electricity?

   I know that Kenya endorses the feed in tariff program to help support renewable energy in their country. But i am not sure on the specifics concerning solar panels. What is the price they guarantee for kilowatts/hour, and how long is that guaranteed? You'll have to check with the Ministry of Energy there. Here is...

5. how to get Solar Electricity cells installed for a Commercial Building ?

   Hi, i just want to know that is it possible to get Solar Electricity for a commercial building.. while I know that it needs the PV cells etc.. and it also needs alternate power source as the electricity generated by Solar Cells might not be enough but post the installation is there any cost one...

6. I want to generate electricity using solar panel and store it in a battery and use it for domestic purpose.?

   I am working on my final year mech proj. to generate electricity using solar panel and a battery, for domestic use. If anyone has knowledge about solar panels and its specifications, pls help me.. thank you.. Most deep cycle, or marine batteries can be charged to 13 volts or a bit more, so don't be alarmed...

7. What countries use solar electricity as a source of energy?

   what countries around the world use solar power to create electricity ( e.i. photovoltaic, concentrating solar power) please leave a web site. thanks! here's section with some articles that could be helpful to you http://renewableenergyarticles.blogspot.com/2009/11/solar-energy.html...

8. Can solar electricity from solar cells panel be integrated with grid?

   Grid connected PV system is applicable for residential. As the name, grid connected system is power generation by solar photovoltaic system that connected to the grid or utility. In a grid-connected (some times called grid-tied systems), solar energy commonly used by owner during day time. At night on the other hand the owners receive power...

9. What time do rooftop solar panels give back surpless electricity?

   I've been told that when you don't use the electricity supply from the solar panels, the electricity is stored up, then at a certain time later in the day, any electricity not used will be fed back into the grid. Is this correct, and if so what time? In the practical sense, that's a good model...

10. What are the types of solar electricity installations?

    There are several types of solar energy system: - The PV Grid-Connected Systems - Stand-Alone Grid-Tied PV Systems - PV Off-Grid Systems - Stand-Alone Off-Grid Systems - Stand-Alone Off-Grid Hybrid Systems Read more details: http://solar-module-panels.com/pv/types-of-solar-electricity-systems/...
