This study is focused on the photometric solution of stars of the G2V spectral type. Photometric solutions light curve analysis in V-band were applied to the sun-like star (BG Vul) located in the ASAS catalog. The light curve of BC Vul showed variation in W UMa (EW/KW) type. Absolute parameters very close to the astrophysical fundamental values of the sun were obtained as a result of the solution. Period variation of the sun-like BC Vul variable star selected from the solar analog star list of Tanriver (2012, 2013) was performed. We conducted an unspotted solution for the BC Vul binary system. The masses of the primary and secondary components for BC Vul were M-1 = 1.017 M-circle dot and M-2 = 0.895 M-circle dot, respectively, while the radius for the primary was R-1 = 1.238 R-circle dot, and R-2 = 1.176 R-circle dot for the secondary. The temperatures of the primary and secondary were T-1 = 5868 K and T-2 = 5520 K, respectively. We revealed that BG Vul is most likely a member of the A-type subclass of W UMa binaries.
