Dennis,
How much does your kWhr usage differ between winter and summer? If you use a LOT more electricity in winter, then adapt an angle that maximizes collection at those months.
With that same steep angle, you will still get a lot of power in summer months simply due to longer day.
The key is to know your winter/summer consumption ratio. Then you can set a rational collection angle.
