Start Here: Beginner Solar Guides (No Risky DIY)
Clear, practical solar basics for homeowners—how systems work, how to size realistically, and how to understand bills and solar credits. We focus on safe planning and questions to ask pros (not electrical installation steps).
Recommended learning path (quick + practical)
- Solar Basics (Start Here) — the core concepts in plain language
- kW vs kWh — understand quotes and your bill units
- Peak Sun Hours — estimate sunlight “fuel” for your location
- Performance Ratio (PR) — a realistic loss factor for estimates
- Net Metering Explained — how credits work and what “net billing” changes
- Why Solar Production Is Low — safe checks before calling a pro
Safety note: For any wiring, panel work, or rooftop installation, consult a qualified professional. This site is for education and planning.

Solar Battery kW vs kWh: The Two Numbers That Decide Backup Power (and Why Most Quotes Confuse Them)
A solar battery has TWO important numbers: kWh (how much energy it stores) and kW (how much power it can deliver at once). This guide explains battery kW vs kWh with simple formulas, real product examples, and a quick table to estimate backup runtime—so you can compare quotes safely without DIY electrical steps.
