As you know, the manufacture of solar photovoltaic needs energy . The factory is a direct source of energy used to manufacture panels with energy to transport panels and components.
In addition, we must not forget the energy required to purchase raw materials and transforming them into parts used to manufacture photovoltaic solar panels, says Fox .
They accumulate quickly, but things must be considered in proper perspective. So did Sally Benson and Michael Dale researchers who have studied the energy needs of industry and the total energy production for Environmental Science & Technology and has published a paper detailing their findings .
The result ? Photovoltaic solar panels generate more energy than they use. These findings can be attributed to changes in solar technology , industrial development and energy consumption in the production panel.
The industry has reached a critical point, and these findings are also in line with what the National Renewable Energy Laboratory found when analyzing solar panels and whether they really provide benefits in terms of energy .
Researchers have focused in particular on the number of years in operation there is a need for a solar panel to generate just as much energy as was used in its manufacture. They concluded that it takes between one and four years as photovoltaic solar panels to " recover " their energy debt .
The couple believes that most photovoltaic solar panels are designed to last between 20 and 25 years with normal use and proper maintenance and more, thanks to their significant gain some energy.
If you plan to opt for solar and have heard this statement, you now have a counterargument: solar panels are definitely the right choice if you want a net gain of energy and environmental impact will be positive, not negative.
