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.
The panels themselves are not really affected by the wind, it is the connection to the roof that needs to be able to withstand heavy winds. Hail damage is also not a big concern, as most panels are rated to withstand one inch hail moving at terminal velocity. See this awesome video to see this in action:
