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.

How to Use NREL PVWatts to Estimate Solar Production (USA): Step-by-Step + How to Read the Results
PVWatts (by NREL) is one of the fastest ways to estimate how much electricity a solar system can produce in your location—especially when you want a reality check before signing a quote. This step-by-step guide shows exactly what to enter (system size, tilt, azimuth, losses), how to read the monthly results table, and how to…

Solar Export Limits & Curtailment (USA): What They Are, How They Affect Savings, and What to Ask Your Installer
An export limit is a cap on how much solar power you’re allowed to send to the grid. When that cap is active, your system may “curtail” output—even on a sunny day—so exports stay under the limit. This guide explains export limits in plain English, shows how to tell curtailment from clipping and shade using…

Solar Battery Backup Reserve: What It Means, Best Settings, and How It Affects Runtime, Savings, and Warranty (USA)
Your battery’s “Backup Reserve” (or “Reserve Capacity”) is the percentage it saves for outages. Set it too low and you may have short runtime when the grid fails; set it too high and you may leave savings on the table. This guide explains reserve in plain English, shows best starting settings by goal, and helps…
