What is the conversion efficiency of Tesla's roof top solar panels?

We don't know yet.From a Fortune article on the announcement:Here Are Important New Details About Tesla's Solar RoofSolarCity's Rive also said that the company thinks it can get to a solar cell cost of 40 cents per watt over time at large scale, which is competitive with current commodity solar panels. But Rive said

Why are roofs a good place for solar panels?

Roofs are typically unutilized surface that is in direct sunlight. Overhanging or nearby trees or taller buildings may cast shadows on a roof and some portions of it will likely slope the wrong way but other than those issues, it makes a great, out of the way location. Aesthetics

Why didn't Tesla use solar on their cars?

Elon Musk doesn't believe that the technology is yet available to provide meaningful amounts of solar power. One thing is for sure, to make it work you have to design the car to provide maximum surface area for the panels, and it needs to be as light and energy efficient as possible

In terms of the efficiency, cost, and feasibility of renewable energy, how does wave energy from oceans compare to wind and solar?

It's difficult to do, but 3/4 of the planet's surface is ocean, so the potential is enormous. Here's some old research that has not been developed -

Would Tesla's solar roof function properly in a colder northern climate? Aside from blocking the sun, would snow damage it in any way?

It all depends on location. Go to: PVWatts Calculator and it will calculate the energy yield for your location. If your location is served by the PVwatts search internet for a calculator that does it. I used previous version of PVwats and the prediction is within very small margin from my PV installation.

How successful are Tesla solar roof so far?

They are doing additional testing before wholesale release into the market. I have heard Elon (in video) saying that he wants to make sure the power outputs are consistent over a period of time.One test house in California has a lot of shading and would not be a good candidate for normal PV systems. But is a

How much do transparent solar windows cost?

Actually, the biggest variable to cost in any kind of window, whether it's solar or standard is size and shape.If you get windows in standard sizes (especially width), you can take advantage of economies of scale and inventory. Get a non-standard width and automatically the price doubles! I've just been through this pricing

When will solar overtake coal in terms of cost?

For meeting peak summer air conditioning demand, especially when transmission is already at capacity, solar is extremely cost effective. Solar is still not enough to meet this demand.For nighttime, it only works if it's time shifted either by storage or by shifting dispatchable power like hydro or by shifting demand; some of these means are cheap, some expensive. However,

How efficient is Tesla's Solar Roof at storing energy?

The Solar Roof DOES NOT store energy. Tesla's Energy storage solution is made by Panasonic.Solar Shingles are much more expensive than standard size panels and cover most of the roof surface anyway to protect it against the sun.Solar shingles have a higher probability of failure because of their number - wired in series may be problematic if not addressed

International Space Station: Why isn't solar thermal power used in space?

Temperature difference doesn't always mean a viable power source. When generating power, quantity is as important as quality. In space, there is only one effective way to get rid of excess heat: radiation. Radiation is the least understood of the methods of heat transfer. At

Are humans more advanced than the aliens that have a Dyson sphere since we got solar panels that can create electricity with stars and it's just small and portable?

No.The only way this could be even remotely true is like this. Alien Dyson sphere big, Terran solar panel small. Both produce same amount of electricity. Terran technology smaller but produce same thing. Therefore Terrans more advanced.But that's not what is happening.A

Could we build a Dyson spheres around our planet? Would this give use enough energy coming from outside to engineer a full ecosystem?

You do not seem to grasp what a Dyson Sphere is. It is a hypothetical structure that completely contains a star. There would be no energy coming in from the outside, no energy leaking out from within.Short answer: We are at least many hundreds of years, if not thousands of years away from

How bad would the economy and industry be affected if once a week at a random day, all grid power was turned off involuntarily?

How bad would the economy and industry be affected if once a week at a random day, all grid power was turned off involuntarily?For the first year it would be pretty bad - but by the end of that year 99% of companies would have arranged some type of power storage or generation facility to cover that gap

Why is solar energy in the most abundant source of energy?

The sun still has around 5 billion years of life left, which means sunlight is guaranteed in the foreseeable future. One hour of sunlight contains more energy than what is needed to power human civilization for a whole year. Consider Australia, where

How will a fossil fuels transition affect the economy?

I assume you are referring to a transition away from fossil fuels. I think for a lot countries like Saudi Arabia, Russia, Venezuela, Brazil,... it will be painful as the bulk of their exports comes from oil. The middle east in particular is heavily dependent on

Are there other solar systems?

To be awfully pedantic and technical the answer is sadly no. The Solar System turns out to be defined as the system of astronomical bodies that orbits the Sun, and there is technically only one Sun (with a capital S), the Sun.HOWEVER, what I think you're trying to ask is

What are some business ideas relating solar energy?

First you need to decide where you want to start your solar business.Then you need to decide whether you are going with existing product or launching your own solar products.Solar is the rapidly growing industry & with such pace innovation matters a lot. So make it sure that you can survive in

How many solar panels would it take to launch a space shuttle?

Luckily, I had already figured out how much renewable electricity would be required to create the liquid oxygen and hydrogen required to launch the Space Shuttle here: Michael Barnard's answer to Are we capable of making rocket fuel out of completely renewable fuel sources? As a result, I only need to do

Would it help to use a solar attic fan in the crawl space of my home?

I think you want a cool and airy home during the sweltering summer, you cannot do without an attic fan. Solar attic fans go a long way to minimising the heat and moisture build up in your attic and upstairs. air circulation in the room

Is Africa going to skip coal and go directly to solar as it continues developing?

I suggest that coal will continue to play its part in many developing countries. Despite recent environmentally friendly regulations, coal will remain an important source of power, especially in non-OECD countries. Between 2012–2040, the IEA predicts that total coal consumption in the non-OECD countries will increase by 0.8%/year, compared with
