NOTICE

For best performance, it is recommended that the collectors face true south.

It is not recommended for the collector field to deviate any further than 45° from true south.

NOTICE

Collector incline should be at least 15° and no more than 70° for best performance.

Avoid installation in shaded areas. Shaded areas will reduce the performance of the solar collectors.
