This is one of the most common arguments. And it has a basis - about 50 years ago, when the productivity of solar panels was extremely low, and the cost of their production was sky-high, people in the northern regions could put them on the roof but did not do this due to the lack of prospects - the angle of their inclination to the sun reduced the already low efficiency. Now we have available panels with an efficiency of about 20-23%, for which the angle of inclination to the sun is not of fundamental importance. You can safely put them and not be afraid of low efficiency.
While it is true that the amount of sunlight that a location receives can affect the efficiency of solar panels, it is not necessarily true that a place is too far north to use solar panels effectively. Many northern states, such as New York, Maine, and Minnesota, have robust solar industries and successfully use solar panels to generate electricity. The amount of electricity that a solar panel system can produce will depend on several factors, including the size and efficiency of the solar panels, the angle at which the panels are installed, and the amount of sunlight the location receives. It's also important to note that modern solar panel technology has advanced significantly in recent years, and many solar panels can now produce electricity even on cloudy or overcast days. So, while the amount of sunlight a location receives is undoubtedly a factor to consider, it is not necessarily a limiting factor when using solar panels.
