It is not possible to connect two 36v solar panels in series to directly charge a 48v electric vehicle. After series connection, it is 72V, so a voltage stabilizing device should be used to stabilize the 72V voltage above 48V and below 55V. It is also important that the power of the solar panel and that of the electric vehicle battery correspond. If the solar panel power is lower than the battery power, the panel may be damaged! Most solar panels have very low power. Indeed, they are often used to power domestic LED lamps. Household LED lights have low power and high brightness, so they do not require large electrical panels. Personal opinions are for reference only
