If you multiply those renewable carbon free kilowatt hours you get.
How much co2 to make a solar panel.
To create a solar panel caustic materials will emit greenhouse gases.
Essentially solar panels produce 77 56 less c02 per kwh of electricity.
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.
You can be very confident that a.
An average residential solar system is 9 kw and would produce about 10 000 kwh in a year.
This includes everything from acquiring raw materials to production to transport and installation.
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.
The carbon footprint of a solar photovoltaic pv panel the average level of greenhouse gas emissions it is responsible for over its lifetime is about 72 grams of carbon dioxide equivalent per kilowatt hour of electricity generated gco2e kwh.
Solar co2 emissions solar panels produce an average of 88 grams of co2 per kwh from manufacture until they are defunct.
