Service for orphaned solar portfolios

For lenders holding loans on systems whose installer closed, and installers taking on customers from a closed company. Twelve31 Energy is building monitoring and coordinated service across many systems at once. We are a platform, not a contractor; repair work is done by independent contractors. Owned systems only; leased and PPA systems are excluded.

Portfolio service is in development. Tell us what you hold and we'll follow up.
