Co2 Emissions To Produce A Solar Panel

The levels of the resulting emissions mostly carbon dioxide and sulfur dioxide can t do much harm to the people working at silicon.

Co2 emissions to produce a solar panel.

The panel is rated to produce 224 watts of power in 1 hour of peak solar intensity. Here s another way to look at it even using lca life cycle assessment wikipedia. So if you live in santa fe new mexico you would generate 6 x 224 watts 1 33 kwh in one day with that one panel. Making and using solar panels emits zero co2 in a 100 renewable energy system.

Most estimates of life cycle emissions for photovoltaic systems are between 0 07 and 0 18 pounds of carbon dioxide equivalent per kilowatt hour. Taking into account the two years to pay off the embedded energy in the panel after 25 years a 6 6kw system will have a net saving of around 243 tonnes of co2. Even at this top end however solar s footprint is very low compared to other sources. By scott cramer although the use of solar panels is green many solar panel manufacturing processes are not.

Solar panels payback the energy in 1. Contrary to the claims of some critics today s research shows that the hidden emissions due to building wind turbines solar panels or nuclear plants are very low in comparison with the savings from avoiding fossil fuels. Energy payback for solar panels is 1 3 years. For instance concentrated solar power csp has a footprint of 20 grams of carbon dioxide co2 per kilowatt hour kwh of electricity produced in addition to consuming vast amounts.

A 6 6kw solar system will produce around 10 600 kwh a year which will save around 10 6 tonnes of co2 emissions per year. Solar panels glimmering in the sun are an icon of. The team found that for every doubling of the world s solar capacity the energy required to make a panel fell by around 12 and associated carbon dioxide emissions by 17 24.
