If you are going big, you should invest in a tracker, which will basically eliminate your responsibility for manually adjusting tilt angles. I think of it as the gold standard for estimating how much solar energy your system will produce. Now, when installingsolar panels for home usage on top of the roof, you need to take into consideration that every location is different, and that something thats a good solution in one state wont be equally appreciated and effective in another. Therefore, to get the very best out of your photovoltaic panels, you would typically face them due south at the optimum angle so that the panel is receiving as much sunlight as possible at this time. The solar tracker above plots the sun's current location with regards to elevation angle (angular measurement above the earth's horizon) and the azimuth (angular measurement from true north). This corresponds to the latitude of the place where you are housing the panels. If you live in a place where it regularly snows, it may make sense to keep the panels at a steep angle (the one suitable for summers) so that the snow easily falls off.
