Why doesn''t solar work during a power outage?
That''s why they''re emergency generators, because even in emergencies, the solar is not the source of energy feeding the site. The only solar grid-tied option that allows the solar to stay operational during an outage is a system with a battery backup because the solar NEEDS to be able to back feed excess production.
Why can''t we put solar panels on the Sahara desert?
Why hasn''t humanity saved itself, putting solar panels on the Sahara desert? For one, solar panels are expensive. This humanity saving project would cost about 514 trillion dollars, equivalent to 23 times the size of the United States economy. Of course, this is all hypothetical. So, what would happen if we were to have unlimited money? What ...
Are solar-powered vehicles still a possibility? | HowStuffWorks
Why can''t we use solar panels to power our vehicles? See pictures of alternative fuel vehicles. Kyu Oh/Getty Images Here we are, deep into a new millennium, and cars are still pretty much the same as they were more than a hundred years ago. Sure, we turn a key instead of a crank to start them, and there have been incredible gains in performance
Electric Cars With Solar Panels: Can They Work?
Solar panels aren''t perfectly efficient technology, as much of the energy collected is lost to heat. The most efficient panels today generate power from about 22.8% of the sunlight it collects.
Why Are Solar Panels So Inefficient?
With concentrations as low as 0.01%, scientists have been able to quadruple the total amount of light absorbed by the solar cell. In conclusion, why solar panels are not more efficient comes down to two things: why blue light penetrates deeper in leaves, and why are organic dyes more efficient than other pigments.

Why America Doesn''t Really Make Solar Panels Anymore
America invented silicon solar cells in the 1950s. It spent more on solar R&D than any other country in the 1980s. It lost its technological advantage anyway.
Solar And Wind Energy May Be Nice, But How Can We Store It?
Renewable energy like solar and wind is booming across the country as the costs of production have come down. But the sun doesn''t always shine, and the wind doesn''t blow when we need it to.
Why America Doesn''t Really Make Solar Panels Anymore
Solar panels aren''t really made in the United States anymore, even though the market for them is larger than ever. Starting in the 1980s, leadership in the industry passed to Japan, then to...

Solar panels, also known as photovoltaic (PV) panels, are innovative devices that convert sunlight into usable electricity. The process begins with the solar panels absorbing photons from the sun''s rays. These photons then excite the electrons in the solar cells, creating a flow of electricity. This phenomenon is known as the photovoltaic effect.
Why Solar Cell Efficiency is Very Low
This fact shows why solar cell efficiency is crucial. It''s still a big obstacle to more people using solar power, despite a huge increase in global solar use. ...

Why can''t we just cover the Sahara with solar panels? — JADE
The solar panels we have so far simply can''t handle that level of abuse regularly. Even if they could, there''s the small issue that all renewable energies face: consistency. The Sahara desert is reliably hot and sunny, but only for 20 hours each day, assuming you had enough solar cells to meet global supply on both sides of the Sahara. ...
Why can''t solar panels work eternally for any space probe?
The damage is caused by micrometeorite impacts. These are tiny particles that hit at high speeds (more than 1 km/s). You can''t build solar panels to withstand that much energy. Also, it''s rare for a mission to end because the solar panels no longer provide enough power. Other factors end the mission long before the solar panels degrade that much:

The efficiency of the currently used solar panels is subject to the fulfillment of different criteria, including the following: Type of solar panel – There are basically three types of panels, of which mono-crystalline solar panels are the most efficient, poly-crystalline panels come in next, and thin-film panels are the least efficient ...
Can solar panels be recycled?
Tao and his colleagues are also pushing for panels to eliminate the small amounts of lead used in the solder that connects the solar cells. Lead is toxic in the environment but nearly worthless when recovered from old panels, which is another barrier to recyclers. Like most recycling issues, solar''s comes down to dollars and cents.
