Design solar parks for the hours that pay.
Noonshift simulates a plant hour by hour against market prices and searches thousands of designs for the one with the highest net present value. The design that makes the most kilowatt-hours is often not the one that makes the most money.
A Windows desktop app. Your project data stays on your machine. Now recruiting design partners for a private beta; general release planned for 2027.

Same site, same grid connection, more value
A 50 MW AC plant on Djursland, in the DK1 price area. Noonshift tested 36,750 designs and compared the one with the lowest cost of energy (LCOE) against the one that earns the highest net present value (NPV).
Typical weather year and 2025 prices
| Setting | Lowest LCOE | Highest NPV |
|---|---|---|
| Layout | Single-axis tracker | Single-axis tracker |
| Ground cover ratio | 0.20 | 0.20 |
| Modules | Bifacial | Bifacial |
| DC/AC ratio | 1.2 | 1.5 |
| NPV | Baseline | +€2.00m (+15%) |
| From hourly prices | €1.50m of it |
2023 weather and 2023 prices
| Setting | Lowest LCOE | Highest NPV |

| Layout | Single-axis tracker | Single-axis tracker |
| Ground cover ratio | 0.20 | 0.20 |
| Modules | Bifacial | Bifacial |
| DC/AC ratio | 1.2 | 1.8 |
| NPV | Baseline | +€6.63m (+18%) |
| From hourly prices | €0.03m of it |
In 2023, hourly prices hardly changed the best design: almost all of the gain came from aiming for value instead of the lowest cost per MWh. In 2025, with 441 negative-price hours, designing for hourly prices was worth three-quarters of the gain.
Results from the Noonshift prototype (v0.1.0), run on 5 October 2026. Investment and operating costs are illustrative defaults, so read the size of the gain as an example. The 2025 case uses a typical weather year, because actual-year satellite weather currently ends in 2023. Yield validation against measured plant data is under way, and the report will be published before general release.

Midday power keeps getting cheaper
As more solar connects, prices fall in the hours when every plant produces at once. A design that moves output away from those hours earns more for each MWh it sells.
Hours with negative day-ahead prices in DK1 in 2025.
Average DK1 price per MWh between 10:00 and 16:00 in 2025, against €111.7 between 17:00 and 21:00 (Danish time).
Capture rate at 2025 DK1 prices
Average price earned per MWh, as a share of the average market price. Prototype model, monofacial modules.
How it works
Five steps, from the weather at your site to the design that earns the most.
- Weather
Hourly irradiance and temperature for your site from PVGIS: actual years 2005–2023, or a typical year.
- Yield
A physical model built on pvlib: diffuse sky light, row-to-row shading, reflection losses at low sun angles, module temperature, the rear side of bifacial modules and inverter clipping. Fixed, east-west and single-axis tracker layouts.
- Prices
Day-ahead prices for DK1 and DK2 from Energinet, for any European price zone from ENTSO-E, or your own price series as a CSV file.
- Value
Revenue at every hour's price, switch-off at negative prices, capture rate, LCOE, NPV and land use.
- Search
36,750 designs: layout, tilt, azimuth, ground cover ratio, module type and DC/AC ratio from 1.0 to 2.2, including plants split into up to three groups, all at your fixed grid connection. A full search takes one to two minutes.
Use it next to PVsyst
Use Noonshift for
- Screening sites before you commit design time
- Choosing between fixed, east-west and tracker layouts
- Sizing the DC/AC ratio for a fixed grid connection
- Testing a design against different price years
Keep PVsyst for
- Bankable yield reports for lenders and investors
Noonshift does not replace a bankable report, and every report it produces says so.
Built for the way your company buys software
For procurement, security and software asset management teams.
