How we build our tools
- Formulas are visible. Every tool shows its equations and where the numbers come from, so you can check the result yourself.
- Assumptions are explicit. Wherever we simplify (e.g. battery Peukert effect or window solar gain), we state the limit.
- Your data stays put. Calculations run entirely in your browser; nothing is sent unless you choose to request a quote.
- Estimates, not final designs. For critical projects, review results with a design engineer or our technical partners.
