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.
However, the main point of the hail test is to make sure that the glass doesnât put people in danger by exploding (the glass can still break and pass). Hail is simulated with a one inch steel ball at terminal velocity that strikes the solar panels at an angle of 90 degrees.
