As pointed out in discussion, lightning protection is a serious art - but
anything you do will help some. I look at it as a lot of effort for a rare
event - but boy! can that rare event be a dilly. As for the power rating, you
should do a bit of research on the power generated by lightning. By
comparison, your 1500 joules is a mouse-fart in a hurricane but as you point
out the trade off is cost of replacement vs. cost of protection amortized by
the frequency of the event.
