solar pv explained
Those who speak English, can you help?
Can you please explain me the phrase ”terrestrial applications” in the following paragraph? I know it’s not easy, but at lease can you say what does this phrase refer to?
”As photovoltaic (PV) solar electricity started 30 years ago, off-grid applications were cost competitive first in remote rural areas. Off-grid solar PV systems for professional and domestic use were the first terrestrial applications.”
The first application of Photovoltaic electricity were for space craft. These were crazy expensive but were the only practical way to power satellites.
The sentence refers to the first applications on the ground. For remote telecommunications or weather observation sites running miles of wire to power commercially would cost a lot. Manning a site to take care of generators could be done, but anelectricityy source that did not require fuel would pay for the upfront cost.
