Pre-wiring for solar
I don't want to instal solar panels in my home but if my roof is damaged by hail or the cost of power goes up significantly in the future then it might be interesting to replace the shingles with solar singles some day. What's involved in pre-wiring the home for solar? Is it just a small conduit to the outside? I presume the conduit can be closed off so as not to leak air in the mean time?
