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.

SRECs Explained (USA): What Solar Renewable Energy Credits (SRECs) Are, Who Can Earn Them, and How to Sell Them Safely
SRECs (Solar Renewable Energy Credits) can add real value to a solar system in some U.S. states—but they’re easy to misunderstand. This guide explains SRECs in plain English, how you earn them (1 credit per 1,000 kWh), where they exist, how to sell them safely, and the key questions to ask so you don’t accidentally…

Solar Self-Consumption Explained (USA): What It Is, How to Calculate It, and How to Increase It (Without Risky DIY)
Self-consumption is the share of solar energy you use in your home instead of exporting to the grid. In many U.S. rate plans—especially net billing and TOU—this one number can change your savings more than panel efficiency. This guide shows how to calculate self-consumption (using your monitoring app or your bill) and how to increase…

Solar Performance Ratio (PR) Explained (USA): The “Real-World Loss Factor” That Makes Solar Estimates Honest
Performance Ratio (PR) is the easiest way to understand why real solar output is lower than “ideal” output. This guide explains PR in plain English, the core formula, typical ranges, what lowers PR, and how to use PR to sanity-check PVWatts and solar quotes.
