I need help understanding panel efficiency when not pointed directly as the sun.

I need help understanding panel efficiency when not pointed directly as the sun.

I recently finished the design of my tiny 12x16 solar home. I am ready to start working on the LiFePO4 battery bank.

I will be using 6 (345 watts) [SunPower X-Series Residential Solar Panels](https://us.sunpower.com/sites/sunpower/files/media-library/data-sheets/ds-x21-series-335-345-residential-solar-panels.pdf).

The roof is oriented (see image) to have an optimal tilt for the middle of each season (where spring and fall share a section).

I am trying to figure out how much power the off season solar panels will produce. For example, if I assume that its mid summer, how do I calculate how much power the fall and winter angles produce compared to the solar that has perfect alignment? Is there a general consensus or is it specific to the panel? If it specific to the panel, what is that called in the datasheet, and what would be the algorithm to calculate it? I would really appreciate the help, I can't seem to find this information anywhere on line.
