6 FAQs about [Air mass ratio max for solar power]
What is air mass in solar energy?
In the solar energy field, air mass is better referred to as the “air mass coefficient” and defines the amount of atmosphere between you and the Sun. As we discussed earlier, the atmosphere absorbs and scatters light, so knowing how much of it is vital to knowing and quantifying the spectrum of light.
