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.
If you have solar panels that are now in use, you can obtain some EMP protection by proper shielding and transient protection on the wires going to the panels, and by surrounding the panels with aluminum wire cloth (also known as hardware cloth). Aluminum wire cloth is somewhat difficult to find, but it is available.
