For summer and the warmer months, it will be 15 degrees minus your latitude. For winter and and the cooler months, the ideal solar panel angle will be 15 degrees added to your latitude..
The optimal angle for solar panels in winter should be 42° + 15° = 57° in winter and 42 ° - 19 ° = 23° in summer..
Generally, the optimal angle is equal to your latitude plus 15-20 degrees in the summer and minus 15-20 degrees in the winter..
For maximum output, the sweet spot for solar panels in the continental U.S. is facing roughly south and tilted between 15 and 40 degrees, according to the Department of Energy. [pdf]
