Часто задаваемые вопросы

Our calculations use industry-standard formulas and real sun hour data for each location. Results are estimates based on average conditions and typical system performance.

The calculator assumes a 30% government rebate, which represents the federal solar tax credit available in many regions. Actual rebates may vary by location.

Solar performance varies based on factors like roof orientation, shading, and weather. We provide realistic ranges to give you a comprehensive view of potential outcomes.

Recalculate if your electricity usage changes significantly, if you move, or if local electricity rates change. Technology improvements may also affect calculations.

Include any high-energy appliances or future additions like electric vehicle charging, swimming pools, or expanded air conditioning usage.
