In 2007, (when t = 0), world solar photovoltaic (PV) marketinstallations were 2826 megawatts and were growing exponentially ata continuous rate of 48% per year.â€Â
(a) Define the variables.
Let S be the world solar PV market installations, inmegawatts, in the month t, where t represents thenumber of years before 2007.
Let S be the world solar PV market installations, inmegawatts, in the year t, where t represents thecurrent year.   ÂÂ
Let S be the world solar PV market installations, inmegawatts, in the year t, where t represents thenumber of years since 2007.
Let S be the world solar PV market installations, inwatts, in the year t, where t represents thenumber of years before 2007.
Let S be the world solar PV market installations, inmegawatts, in the year t, where t represents thenumber of years before 2007.
