Size Of Solar Panels To Power The World

How do we arrive at this number.

Size of solar panels to power the world. Physically speaking the panels are about 65 inches by 39 inches for residential installations and they weigh about 40 pounds per panel. Yet you can also find panels of 150 160 or 175 watts. 6 2 kwh x 1000 convert to watts 6200 watts solar panel required. Consumes about 4 petawatt hours of electricity per year we d need about 13 600 000 acres or 21 250 square miles of solar panels to meet the total electricity requirements of the united states for a year.

By the end of 2019 a cumulative amount of 629 gw of solar power was installed throughout the world. Map courtesy of google maps. The yellow square is approximately 21 000 square miles. The solar panel with the highest watt is the sunpower e series a commercial solar panel line.

How much are 21 250 square miles. 50 watt 100 watt and 160 watt. Here we are supposing a panel size of 350w for the calculated size of 18tw of solar plants. As mentioned before each manufacturer has its own solar panel sizes and wattages sweet spot.

Solar panels used for commercial sites are a little bigger but that s because commercial buildings are usually larger and can contain the size of the panels. 33 kwh 6 1 sun hours x 1 15 efficiency factor 6 2 kw dc solar system size required using the example above with a 6 2 kw dc system you can multiply this number by 1 000 to confirm that you need 6 200 watts of solar panels. A total of 51 42 billion solar panels would be needed to power the entire world on solar energy. It would only take 191 817 square miles of solar panels to power the entire earth.

The top panel in the e series comes out at a whopping 435 watts. According to the analysis we would need around 1 1 million square kilometers of solar panels to power the whole earth or an area the size of south africa. That s roughly the size of spain. Solar panels usually range in wattage output from around 250 watts to 400 watts but some panels exceed the 400 watt mark.

By early 2020 the leading country for solar power was china with 208 gw accounting for one third of global installed solar capacity. Solar power is more powerful than many people realize. You ll need 6 2 kw dc according to the formula. We receive a staggering 1 74 1017 watts of energy from it.
