ergOptimize is our advanced simulation driven offering designed to de-risk and accelerate your solar project development. Whether you're exploring a new site or building a solar & BESS portfolio, we provide precise analytics, optimized system design, and clear investment-grade insights tailored to your goals.
Simulation-Ready Timeseries Data
We deliver highly accurate energy generation timeseries data for your solar and hybrid renewables simulations. ergLocale's simulation-ready datasets include:
Multi-source irradiance validation and temperature profiling
Historical timeseries instead of only TMY solar data
Location, equipment & design specific energy timeseries
Beyond hourly resolution for high-stake projects
System Configuration Modeling
Our proprietary simulation tools for high-resolution energy timeseries unlocks comprehensive solar PV planning by evaluating all possible equipment and configuration mixes:
Tracker vs. fixed-tilt evaluations
DC stringing, tilt, pitch, and DC/AC ratio optimization
Energy & cost matrix for hundreds of comparisions
Identify the project configuration having the highest return on investment and beat your competition
Layout Design
Site-adapted layouts for ground-mounted and rooftop solar:
Optimized PV stringing design for higher performance and lower cost
BESS & inverter siting
Land-use, terrain and other constraints via SRTM, satellite imagery and stakeholder inputs
Achieve high-quality layouts in CAD and PDF formats for planning discussions and approvals
Energy Yield Assessments
We conduct detailed energy modeling using PVsyst for optimized designs:
P50, TMY and historical energy timeseries simulations
Expert considerations for loss factors including soiling loss and electrical losses due to shading in complex urban environments
Get detailed comparison of energy yield and design
Battery Storage Assessment
Solar-BESS pairing analysis
Optimal sizing recommendations and qualitative cost-benefit insight
Prevent wrong-sizing BESS and design profitable DC-coupled systems

Khanh-Loc Nguyen,
CEO
"Tomsawyer helped us clearly understand the long-term techno-economics of distributed energy asset and sensitivities with respect to configuration changes. They were very collaborative and provided efficient and highly professional support."
Andrew Koh,
Managing Director
"It was a pleasure to collaborate with you, and I really appreciated the fact that you understood our sense of urgency and managed to adapt to our short timelines. The pre-feasibility study documentation was according to our expectations, and you even went beyond with helping us selecting some initial equipment to provide energy estimations"
William Gaillard,
Wind Head
"the ergLocale team was instrumental in supporting the technical layout design for our first utility-scale solar development in the UK, up to securing planning consent. Their sound knowledge of solar optimization enabled the production of an efficient layout, integrating DC-couple BESS."
