Does solar pencil out with our winters?expand_more
It depends on actual usage, shade, orientation, equipment, modeled production, current utility terms and total installed scope. Require the assumptions rather than a generic payback claim.
Should I lease or buy?expand_more
Compare total payments, ownership, maintenance, warranties, production promises, transfer terms, escalators and end-of-term obligations with qualified financial and legal advice.
Can I put an array on my shop instead of the house?expand_more
Possibly. Compare shade, roof structure and life, attachment method, electrical route, meter relationship, permits and utility interconnection for that building.
How long does the whole process take?expand_more
Ask the proposal to separate design, permit review, equipment delivery, installation, inspection, utility authorization and meter steps. External approvals control the actual date.
Does the installer obtain the electrical permit?expand_more
Washington L&I states that a hired electrical contractor obtains its own electrical permit for the work it performs.
When can the system export power?expand_more
Only after required building and electrical approvals and the serving utility's interconnection and authorization steps are complete.
Does a solar array provide power during an outage?expand_more
Not automatically. Outage capability requires a specifically designed transfer and backup system; define critical loads and operating modes.
What should I receive at closeout?expand_more
Keep permits, inspections, utility authorization, equipment schedule, settings, monitoring access, baseline operation, photographs and warranties.
