If the BK doesn't come up on a google search, there is no other way to find a BK that would be cheaper than PACER. If the person has a common name, that will obviously be a problem. But, if you know in which jurisdiction they filed, you should be able to find the case and won't incur $10.00 worth of charges. It really won't be that expensive.
Hail larger than 1 inch in diameter (golf ball- or baseball-sized hail) can cause considerable damage to panels, although hail of this size also generally causes damage to most structures. To protect your solar panels, a solar panel protective cover is recommended during the times when hail is expected.
That being said, solar panels utilize IR, UV, and visible rays from the sun that can penetrate through clouds. Although the efficiency of the solar panel will decrease in cloudy conditions, you'll still be collecting valuable power from the sun.
