I sat down and interviewed Amy from West Seattle Natural Energy a couple weeks back. We recorded a 30-min podcast covering lots of info on WA-state financial incentives, whether to use WA-state panels & inverters to maximize the payback credit, and plenty more.
The full audio and transcript can be found here: Seattle Solar Q&A. The transcript weighed in at 4500 words, so plenty of reading.
Amy will be answering questions so if you have any, just leave them in the comments on that post.
