Solar Calculator Pro

Solar Calculator Pro – Solar System Design, Sizing & Cost Calculator Solar Calculator Pro is a professional solar system design and sizing calculator for homeowners, solar installers, electricians, contractors, RV owners, off-grid users and anyone planning a solar power system. Calculate solar panel sizing, battery sizing, inverter sizing, energy requirements, system costs and solar payback, then save your design and export a professional PDF report. SOLAR SYSTEM DESIGN & SIZING Design and size complete solar power systems based on your real energy consumption and available sunlight. Build your load appliance by appliance or enter daily energy usage to calculate the system you need. ★ Solar Panel Sizing Calculate required solar panels, panel count and total solar array size in watts (Wp) based on energy consumption and local sun hours. ★ Battery Sizing Calculate battery capacity in kWh and Ah, with support for 12V, 24V and 48V systems. Account for autonomy days and depth of discharge when sizing your battery bank. ★ Inverter Sizing Calculate a recommended inverter size based on your system load and energy requirements. ★ Solar Load Calculator Build an appliance load list and calculate daily energy consumption from your actual electrical loads. ★ Off-Grid Solar Planning Plan solar systems for homes, cabins, RVs, backup power and other off-grid applications. SOLAR COST & FINANCIAL CALCULATORS Know what your solar system could cost before buying equipment or requesting installation quotes. ★ Solar Cost Calculator Estimate the cost of panels, batteries, inverter, mounting, wiring and installation using realistic low-to-high cost ranges. ★ Solar Payback Calculator Calculate your solar system payback period, annual savings and break-even point based on electricity usage and energy rates. ★ Solar Savings & CO₂ Estimate yearly energy savings and annual CO₂ offset from your solar power system. SOLAR PROJECT PLANNING Save complete solar system designs as projects and return to them whenever you need. Each saved solar plan keeps your panel sizing, battery capacity, inverter size, system cost, payback and other project details organized in one place. Compare different solar designs for homes, RVs, cabins and other projects. PROFESSIONAL PDF SOLAR REPORTS Export a professional PDF solar system report from any saved plan. Reports include system specifications, component requirements, itemized cost estimates, shopping checklist and payback information. Share your solar design with installers and contractors or use the report as a buying and planning guide.
