$RUN has had a tremendous year, but it’s not done yet. Sunrun merged with Vivint, a previous top competitor in the residential solar space with massive sales teams across the country.

Retained value is the present value of all cash flows from residential solar projects. With power purchases agreements and leases, customers sign 20 (now 25) year contracts to purchase electricity from $RUN, the lease provider (& installer, etc), which pays for the installation

allowing homeowners to go solar for $0 out of pocket and save immediately. $RUN now has $2.72B of net retained value after merging with Vivint. Compare this to $368M with $SPWR.

$RUN is considered to be the top option in the industry (especially for lease product based systems) and is expected to be going forward. $NOVA however is one to watch as they are probably the closest competitor and is making significant strides in gaining market share.
