Solar Insight Pro — Free Solar + BESS Feasibility Design for Factories
LEONICS engineers use Solar Insight Pro — a proprietary engineering-grade platform — to deliver a complete Solar + BESS feasibility study for your facility. 35,040-interval simulation, real Thai TOU tariff modeling, demand charge ratchet analysis, and a 25-year NPV/IRR/payback report. Free service, no obligation.
⚐ Send your 12 months of electricity bills + tariff type → receive a One-Page Feasibility Report within 1-2 weeks · No charge · No obligation
From your electricity bill to a feasibility report in 4 steps
Unlike a generic calculator, Solar Insight Pro runs a full 35,040-interval simulation (15-minute resolution × 365 days) against your real load profile and Thai tariff structure.

What's inside Solar Insight Pro
Built by LEONICS engineers for utility-grade analysis — the same tool we use internally for hundreds of factory and IPP projects.
- 35,040-interval load profile analysis — 15-min resolution × 365 days from your real bills
- Real Thai TOU tariff (MEA/PEA) + FT + Demand Charge
- Peak Shaving + Arbitrage Optimization — find ESS dispatch strategies that minimize bills
- Demand Charge with Ratchet Analysis
- 25-year NPV / IRR / Payback / LCOE — module + ESS degradation + replacement costs included
- BOI tax depreciation (Thailand) — 150% × 3 years
- Utility Bill Validation — model is calibrated against one real monthly bill before final report
- One-Page Feasibility Report — board-ready, easy to share with stakeholders
Who is this service for?
Designed for large electricity consumers where a generic online calculator can't capture demand charges, TOU complexity, or ESS dispatch economics.
- Factories (electricity bill > 500,000 THB/month)
- Large commercial buildings
- Cold storage / Logistics warehouses
- Data Centers / Hospitals
- Solar farm developers / IPPs
- Sites with high demand charge (> 100 kW)
