What's New in Solar Calibrator

2.1.0

November 8, 2026

Version 2.1 brings a rebuilt Quote tool and more precise calculators. QUOTES • Quotes save automatically. Open, continue or delete them from Saved Quotes. • Add items from a searchable catalog or your recent items, with their last price. • Lines are grouped into Hardware and Other. Long-press a line to move it. • Labor as a fixed amount or a percentage of hardware. • New PDF: quote number, date, valid-until, customer, grouped table and one grand total. CURRENCY • Your currency is picked from your region, with correct symbols and grouping (including lakh grouping for INR, PKR, BDT and NPR). • Choose another in Settings → Currency. Each quote keeps the currency it was made in. CALCULATORS • Every result now shows the working behind the number. • Array: enter your panel wattage to get the panel count, installed kW and panel area. • Battery: sizing now accounts for depth of discharge (lithium vs. lead acid), so results are more realistic. • String sizing: add Vmp and the MPPT minimum to get a minimum and maximum string length. • Tilt: year-round angle from published formulas, plus which way to face your panels. • Obstruction: works at the equator and for sites where the winter sun stays below the horizon. ALSO • Now in Hindi, Urdu, Spanish, French and Uzbek. • Smoother keyboard handling and scrolling in long lists. • Bug fixes and stability improvements.
