The best solar installers in South Dakota
South Dakota is a small residential solar market — the strongest installers concentrate in Sioux Falls (eastern SD) and Rapid City / Black Hills (western SD), with a thin layer of statewide-coverage companies in between. This list keeps the top picks to 4 installers spanning both halves of the state. If you can't get three bids from in-state installers in your region, supplement with one of the regionals under Honorable mentions.
GenPro Energy Solutions Local
Why listed: Piedmont-headquartered (Rapid City metro) regional installer — the longest-tenured SD-HQ solar company actively taking new residential contracts. Residential and commercial PV plus battery storage. Statewide SD coverage plus operations in ND, NE, and WY. The strongest overall SD-based pick for both Black Hills and east-river homeowners.
Black Hills Solar Local
Why listed: Rapid City-based residential and commercial solar installer with focus on the Black Hills region. Locally-owned with strong reputation for residential PV and battery storage. Best in-state option for Pennington, Lawrence, and Meade county homeowners alongside GenPro.
Wegner Roofing & Solar Local
Why listed: Sioux Falls-based combined roofing and solar contractor — the strongest in-state option for Minnehaha, Lincoln, and Brookings county homeowners. Especially useful when reroofing is in scope alongside the solar install (single contractor handles both trades, single workmanship warranty). Locally-owned.
Solar Pro (Black Hills) Local
Why listed: Rapid City-headquartered residential and commercial solar installer — the strongest in-state option for western SD homeowners in Pennington, Meade, and Lawrence counties where eastern-SD installers face long drive times. Maintenance and support services for existing systems alongside new installs.
National installers National
Sunrun, Tesla Energy, and Palmetto Solar are the major national installers still actively taking new residential contracts as of 2026. Palmetto Solar currently holds EnergySage's Elite+ tier — the platform's highest installer rating. National installers typically have larger sales footprints but also higher financing markup and more variable local service quality than the state-based installers above.
Avoid — recently bankrupt or exited: Sunnova (Chapter 11 June 2025), the original SunPower (Chapter 11 August 2024 — the current "SunPower Inc." is rebranded Complete Solaria, a separate company), ADT Solar (exited residential solar January 2024 — warranty service only), Trinity Solar (East Coast only, doesn't serve most states), and Freedom Forever (Chapter 11 April 2026). If a salesperson contacts you under any of these brand names, ask which legal entity is actually signing the contract and warranty.

Other South Dakota-based installers
Ritter Solar Local
Why listed: SD-based residential solar designer and installer with statewide service coverage. Smaller company — worth a quote for homeowners who want owner-led project management rather than a sales-team-led approach.
Black Hills Solar Local
Why listed: Rapid City-based residential and commercial solar and energy-storage installer covering western SD. Worth a quote alongside Solar Pro for any project in the Black Hills region — both are local-to-the-Hills options for homeowners and small businesses comparing pricing and design approaches.
Regional installers serving South Dakota
Worth a quote if you're in eastern South Dakota (close to Minnesota or Iowa) — expect longer drive times for service calls than an SD-HQ installer.
All Energy Solar Regional
Why listed: Twin Cities-headquartered EnergySage-screened residential installer with active service area covering eastern South Dakota from MN and IA. NABCEP-certified design staff. Best regional fit for Sioux Falls-area homeowners who want a larger, more established installer alongside the SD-HQ options.
Lightspring Solar Regional
Why listed: North Dakota-headquartered residential solar installer with active SD coverage. Tesla-equipment focused. Worth a quote for northern SD homeowners (Brown, Spink, Edmunds counties — Aberdeen region) close to the ND border.
