Frequently Asked Questions
What is your guarantee for accuracy of solar energy yield forecasts?
Finulent ensures high-resolution weather data and irradiance maps coupled with minute-level simulations in software such as PVSyst, Helioscope, and OpenSolar, among others to create precise performance projections for UK geography and site-specific conditions. Our accuracy in energy yield predictions directly supports reliable solar panel quotes, enabling informed investment decisions backed by data.
Do you offer software-specific modeling, i.e., with Helioscope solar design software or PV*SOL?
Yes. Depending on your requirements or technical preferences, we can provide Helioscope, PV*SOL, Aurora Solar, or AutoCAD-compatible output for performance analysis, string configurations, and component planning. We work with some of the best solar design software in the industry to ensure high-precision, data-driven proposals tailored to each site.
What is your typical turnaround time for a complete solar proposal?
Depending on the project size, our average proposal delivery time is 24-48 hours, including 3D modeling, financial analysis, component sourcing, and revision cycles. Our team follows a professional solar proposal writing approach, ensuring each document is technically accurate, visually clear, and ready for stakeholder review.
Can your proposals include Battery Energy Storage Systems (BESS) and their ROI?
Yes. We incorporate battery performance modeling, backup analysis, and BESS ROI calculators to prove incremental savings, payback reduction, and improved self-consumption, critical for commercial customers to tackle peak loads. Using some of the best solar proposal software, we deliver data-rich insights that help justify BESS investments with clarity and confidence.
