The present application relates to a method for manufacturing a vacuum solar thermal panel which comprises at least a tempered glass plate and a metal frame attached to said plate, the method comprising a fit firing cycle to form a glass-metal seal, the fit firing cycle comprising a first heating phase of the tempered glass plate up to a maximum temperature (Tm), being the temperature which preserves a suitable pre-stress level of the tempered glass plate. Advantageously according to the invention, the method further comprises a second heating phase (via optical radiation illumination) being a selective heating phase of a melting area of the tempered glass plate performed at a second temperature (Th) which is above the maximum temperature (Tm).
