Residential installations grew 7 percent last year; more than expected by analysts at energy research and consulting company Wood Mackenzie Power & Renewables.

But there’s still a good bit of uncertainty in the market considering global module oversupply, declining module tariffs, as well as the coming stepdown of the Investment Tax Credit. Through 2021, analysts at WoodMac said residential growth could range from 4 to 19 percent.

It’s within that context that EnergySage, an online solar shopping marketplace, released its latest Solar Marketplace Intel report this week, which focuses on the residential market.

The results offer valuable takeaways about price declines for residential systems, the increasing interest in residential solar across the U.S. and how U.S. panel manufacturers are faring post-Section 201 tariffs. But analysts say the report's result should be considered according to the portion of the market that EnergySage’s transactions represent. Though it’s among just a few online platforms for selling and buying solar, the marketplace still encompasses just a small segment of total residential sales — about 3 to 4 percent of the residential market, according to EnergySage.
