Which numerical weather models do you use?

Ensemble of ECMWF, GFS, and ICON, blended on each plant's historical performance. We retrain weekly on your SCADA data.

What forecast horizons are available?

Intraday (15-min), day-ahead (hourly), and 7-day. P10 / P50 / P70 / P90 confidence intervals on every horizon for risk-aware bidding.

How do you measure accuracy?

nMAE against actual generation, reported daily per plant. Customers typically see 4-6% nMAE day-ahead on stable continental sites.

Do I need to provide historical data?

A 90-day SCADA window is enough to deploy a custom model. Cold-start uses a continental baseline.

AI Solar Production Forecasting — Up to 97.8% Accuracy

Tomorrow's revenue, today.

DYNVOLT forecasts production 24 hours ahead with up to 97.8% accuracy. P10/P50/P70/P90 confidence bands let you bid the day-ahead market with risk-adjusted curves — not gamble with single-point estimates.

Confidence bands

Two forecasts. One bid envelope.

Solar revenue is a product of how much you produce and what the market pays. Most platforms predict one. DYNVOLT predicts both — and stitches them into a single risk-adjusted dispatch signal so traders bid against an actual P&L distribution.

FOR ENERGY TRADERS

Nominate the whole book. Not one plant at a time.

A trader managing eight owners across four bidding zones gets one rolled-up forecast per zone — already netted, already imbalance-priced, already in the format the BRP needs to nominate.

One nomination per zone, not per asset

Production roll-ups across every plant the trader represents — netted by zone, ready to drop into the BRP nomination file.

Price & imbalance forecast on the same axis

Day-ahead, intraday, and imbalance settlement curves — overlaid on production so the bid envelope is a P&L envelope.

Cross-border spread signals

Eight neighbouring zones forecast in parallel. The optimizer flags when a neighbour's spread widens enough to reroute through coupling.

Auto-bid with risk envelopes

Place day-ahead bids at P50 with imbalance hedges around P10/P90. The trader sets the risk corridor — DYNVOLT places the bids.

An ensemble built for solar.

DYNVOLT's forecast engine combines a numerical weather prediction (NWP) backbone with site-specific gradient boosters trained on every kWh ever measured at your plant. Output is a probability distribution, not a single number.

Per-block models — every block of the plant gets its own ensemble.

Multi-source weather — ECMWF, GFS, ICON, and on-site sensors fused into a single feature set.

Continuous re-training — models refresh nightly with the latest data; drift is monitored automatically.

Back-test transparency — every forecast is benchmarked against actuals. MAPE published to your dashboard daily.
