About StraightUp Solar
A turnkey EPC for Missouri and Illinois homes
StraightUp Solar describes itself as a full service, turnkey solar EPC company, meaning it handles the engineering, procurement and construction of the projects it sells. It is headquartered at 10601 Trenton Avenue in St. Louis, Missouri, and lists an Illinois office at 505 North Main Street in Bloomington. The company says it has brought more than 3,000 solar systems to light since 2006, and that its local team manages each residential project from design to build to maintenance.
The company presents itself as a local installer in the two states it serves rather than a national sales organization, and its residential page invites homeowners in Missouri and Illinois to start with a free, no-obligation quote.
What a StraightUp system includes
The company explains a home system as one connected network. Solar panels collect sunlight and generate direct current electricity, an inverter converts it to alternating current the home can use, and any excess is sent to the local grid in exchange for net metering credits the household uses at night. Owners can track the array's production and efficiency online. Most homes it serves use rooftop arrays; ground mounted arrays are an option for properties with more land.
Battery storage is offered in several sizes, which the company describes as ranging from keeping certain appliances running during an outage to powering an entire home in an emergency. It also offers pairing a system and battery with a smart panel for control over individual circuits, and it sells service plans for systems after installation.
- Custom residential solar design and installation
- Battery storage, from critical loads to whole home backup
- Electric vehicle charging and smart panels
- Service plans and system maintenance
The people and credentials the company points to
StraightUp Solar says its projects are created by in-house design and installation teams, which oversee a project from start to finish rather than handing it to outside crews. It states that about half of its team members are NABCEP certified professionals, describing that credential from the North American Board of Certified Energy Practitioners as the industry standard for solar professionals. The company is a member of Amicus Solar, the nationwide cooperative of independently owned solar companies, and it has been a Certified B Corporation since 2015, per its site.
Workmanship warranty and production guarantee
On top of the manufacturer's 25-year warranty on equipment, the company offers a 10-year workmanship warranty and a 10-year production guarantee, both stated on its residential page. The production guarantee is the commitment to read in a written quote, because it is the company's own promise about the energy a specific system will produce. Financing routes the company describes include a home equity line of credit, a loan through the Clean Energy Credit Union, and a power purchase agreement in Illinois only.
