Solar Design Services in Indiana
One engineering partner across the whole project lifecycle in Indiana. Proposal drawings to win the job, permit sets to get it approved, detailed engineering to get it built.
Client and engineer figures are portfolio wide across 15 countries. Installed capacity is Indiana specific.
INDIANA DESIGN SERVICES
Engineering capacity for the Indiana market
Indiana is a market where the design has to work harder because the export economics are weak. With excess generation credited well below retail, sizing follows the consumption profile, west-facing orientation gains value where afternoon load peaks, and storage moves from upsell to core economics. Honest production modelling matters more here than in retail netting states because there is less margin for an optimistic estimate.
MARKET CONTEXT
The Indiana solar market
Indiana solar operates against one of the least favourable export structures in the Midwest. Retail net metering has been phased out for new systems, replaced by excess distributed generation credit at a rate well below retail, with legacy protection only for systems interconnected before the statutory cut-offs. The practical consequence is that Indiana projects live or die on self-consumption, which pushes storage, load matching and honest production modelling to the centre of the design rather than the margins.
Retail net metering has been phased out for new systems, replaced by excess distributed generation credit at a rate substantially below retail.
That makes self-consumption the entire value case, so load matching and storage are central rather than optional.
Commercial projects need state design release in addition to local permitting, which is a second submittal rather than a formality.
Southwestern Indiana carries modestly elevated seismic categories from New Madrid influence that the north of the state does not.

INTERCONNECTION
Indiana utilities we design for
Export compensation decides how a system should be sized and whether storage belongs in the design, which makes it an engineering input rather than a sales detail.
| Utility | Territory | Export and compensation |
|---|---|---|
| AES Indiana | Indianapolis and central Indiana | Excess distributed generation credit rather than retail net metering for new systems |
| Duke Energy Indiana | A broad territory across central and southern Indiana | Excess distributed generation credit, with its own application and metering requirements |
| NIPSCO | Northern Indiana | Excess distributed generation credit, separate interconnection process |
| Indiana Michigan Power | Fort Wayne and northeastern Indiana, part of AEP | Excess distributed generation credit with its own terms |
| CenterPoint Energy Indiana | Evansville and southwestern Indiana | Excess distributed generation credit and separate application handling |
ENGINEERING CONDITIONS
What governs design in Indiana
These conditions decide the structural approach, the racking selection and often the layout itself. We verify them per site rather than applying a regional default.
Wind
Moderate, with tornado-zone considerations and open-terrain exposure on rural sites
Snow
Roughly 20 to 25 psf across most of the state, somewhat higher in the north
Seismic
Low across most of Indiana, with modestly elevated categories in the southwest closer to the New Madrid zone
Also governing
Freeze-thaw cycling affects attachment and flashing detail, and cold winter temperatures raise string open circuit voltage
Compliance scope in Indiana
- Indiana building rules adopted statewide with local enforcement
- State design release required for commercial construction in addition to local permits
- Excess distributed generation credit replacing retail net metering, at a rate substantially below retail
- Legacy net metering protection for systems interconnected before the statutory cut-off dates
Indiana authorities we file with
Each has its own submittal route and recurring review comments. Full detail on the Indiana permit design page.

Working with an India based partner on Indiana projects
We are based in Surat, Gujarat, and our Indiana clients are not. Our engineers work hours that overlap US time zones, so work sent at the end of your day is on your desk the next morning.
On code, the same engineers who produce CEIG approval drawings for an Indian utility also produce NEC compliant sets for US installers. Working across code frameworks daily is why Indiana specifics do not get lost in handoff. Work is covered by NDA and intellectual property transfers to you.
