New solar, expansions, and upgrades in Arkansas

Engineering knowledge, grounded in field work

Perihelion is an engineer-run company with two full-time engineers. A master electrician and a PhD in electrochemistry contribute electrical and battery expertise. That knowledge helps us compare equipment, explain the tradeoffs and plan how the system fits your property.

Our field experience includes maintaining large industrial solar arrays and construction subcontracting in panel wiring, electrical work, panel mounting and racking. It helps us consider access, installation details and future service while the project is being planned.

How we choose the equipment

• Your electric use and expected changes help set the solar and storage goals.
• Shade, roof condition, usable land and cable distances help determine rooftop or ground-array placement.
• For backup, we check both daily energy use and the power needed to start and run selected appliances.
• Existing equipment, electrical service, monitoring and applicable utility requirements affect the connection and expansion options.

From your first idea to an installed system

1. Goals and preliminary plan. Share your location, electric bills and priorities. The visual planner lets you try layouts, appliances and batteries before a consultation.
2. Site and electrical review. Review space, shade, mounting, service equipment and the connections needed for the proposed system.
3. Proposal and required approvals. Confirm equipment, included work, allowances, applicable permitting and utility requirements. Review the written scope and price before approving work.
4. Installation and handover. Complete the agreed installation, setup and commissioning, then review the equipment, monitoring and ongoing support with you.

The sequence and schedule depend on the property, equipment and required approvals. Online estimates are a starting point for the site-specific proposal.

A look at our commercial field work

For a rooftop example, see the 68.4 kW DC system Perihelion installed at All Saints’ Episcopal Church in Russellville in 2021. Explore the church project.

Match the project to your next step

• New residential rooftop and ground-mounted solar
• Review of existing-system capacity and expansion options
• Inverter, monitoring, and equipment upgrades
• Solar and battery planning for daytime use and overnight needs

More panels are not always the best first change. Your usage pattern, roof or ground exposure, equipment limits, and utility arrangements all influence the design. For an expansion, we review the existing system before recommending additional equipment.

What to have ready

Share recent electric bills, the service address, and any planned changes such as an electric vehicle or different heating system. For an existing array, include equipment details and monitoring access information if available. Photos and a sense of your priorities—energy use, backup, or expansion—help guide the first discussion.

What happens after you contact us

We review your goals and usage, discuss site options, and develop a preliminary scope. Site conditions, equipment compatibility, and applicable utility or permitting requirements are confirmed as the project develops. A written proposal sets out the equipment, installation work, and estimate.
