Are Solar Panels More Efficient Than Plants

If we think technically though it s possible solar cells produce more oxygen than plants and gather more energy in a form that wouldn t need.

Are solar panels more efficient than plants.

Utility scale solar uses much more land than a coal power plant since each solar panel needs to face the sun and can t be shaded by other panels. According to the wikipedia page on photosynthetic efficiency typical plants have a radiant energy to chemical energy conversion efficiency between 0 1 and 2. Plants have to power a living thing whereas solar cells only have to send electricity down a wire. This number is enough to power only 500 000 homes which is considerably less than nuclear power.

Reflectance efficiency is determined by how much sunlight is reflected back instead of absorbed and put to use. Compared to solar panels wind turbines release less co2 to the atmosphere consume less energy and produce more energy overall. The ultimate way to compare solar energy to fossil fuels is by cost where solar has quickly caught up with its non renewable counterparts. The less reflection in solar cells the better.

This is a big difference because if photosynthesis makes a mistake it makes toxic byproducts that kill the. Most commercially available solar panels have more than 10 times this efficiency. Based on the photon enhanced thermionic emission pete process a new solar energy device is about 100 times more efficient than its previous design. Wind is a more efficient power source than solar.

But here s the worst part. Scientists working at the stanford institute for materials and energy sciences simes have improved an innovative solar energy device to be about. Plants are less efficient at capturing the energy in sunlight than solar cells mostly because they have too much evolutionary baggage. Solar enthusiasts argue that as their industry gains scale and the cost of producing.

So solar power is more expensive than all these other forms of alternative energy. Photosynthesis is less efficient than solar panels. As a result these panels tend to cost less than the more efficient monocrystalline panels. For solar to produce as much electricity as is generated by a nuclear power plant it would require about 13 000 mw of utility scale solar capacity which about four times as much as built in the existing plants.

The 550 mw desert sunlight solar farm for example is one of the largest solar power plants in the world with 8 8 million solar panels covering six square miles. In terms of environmental impact solar power is a much more optimal resource than fossil fuels.
