Solar power bible

What is a solar powered audio Bible?

This rugged, little, solar audio Bible is being used worldwide to communicate with non-readers, illiterate, visually impaired and blind people. Because the MegaVoice is solar powered, our audio Bibles are totally independent of electricity. Solar powered is a valuable feature in countries like India where millions are without electrical power.

When was solar PV invented?

Solar PV was invented in the 1950s, and began to be used in appreciable volumes for utility-scale electricity generation in the US in the early 2000s, but only around the 2010s did it start to become a large share of planned generation projects worldwide. Since then, solar generation capacity has grown incredibly quickly.

How much power does a solar PV system produce?

The average capacity factor of utility-scale solar PV in the US is around 23%, meaning that on average they produce 23% of the power they would if they were exposed to 1,000 watts per square meter of sunlight 24 hours a day.

How much energy does a 21% solar panel produce?

So a 21% efficient solar panel will have a maximum output of 210 watts per square meter. For a given spot on the Earth’s surface, irradiance will start at 0 watts per square meter when it’s completely dark, gradually rise to its maximum, and then fall back to zero at night.

Is solar PV a small potato?

In the US, solar PV projects are by far the largest share of planned new electrical generation capacity. Of the roughly 1,900 gigawatts of electricity generation projects in the interconnection queue, around 50% of them are some type of solar PV project. But while solar PV is growing rapidly, in absolute terms it’s still fairly small potatoes.

How fast does solar power grow?

Since then, solar generation capacity has grown incredibly quickly. By some metrics, solar PV has been deployed faster than any other energy source in history, going from 100 terawatt-hours of generation to 1,000 terawatt-hours in just 8 years, compared to 12 years for wind and nuclear, 28 for natural gas, and 32 for coal.
