About PVSize

Last updated: June 25, 2026

Who We Are

PVSize is an independent research publication dedicated to helping homeowners and solar shoppers make informed decisions about photovoltaic system sizing. We provide free, data-driven calculators, in-depth buying guides, and industry analysis based on publicly available data from authoritative sources.

We do not sell solar panels, inverters, batteries, or any physical solar equipment. We do not operate an installer network, nor do we facilitate installer-consumer matchmaking. Our revenue comes from advertising, affiliate partnerships, and B2B services for solar manufacturers — all of which are clearly disclosed per our Sponsored Disclosure Policy.

Our Editorial Team

All content on PVSize is researched and written by our AI-assisted editorial team, reviewed independently by senior editors.

We maintain a strict policy against using protected professional designations (P.E., NABCEP, Ph.D., Dr.) in our bylines unless the individual contributor holds an active, verifiable credential. Our content is attributed to the PVSize Editorial Team to avoid misleading readers about qualifications we do not possess.

Data Sources & Methodology

Our calculators and analyses draw primarily from the following public and authoritative data sources:

NREL (National Renewable Energy Laboratory) — PVWatts methodology for solar irradiance and production estimates; SAM (System Advisor Model) for financial modeling
IEA (International Energy Agency) — Global PV market data, technology trend reports, and policy databases
SEIA (Solar Energy Industries Association) — US market statistics, state-level policy tracking, and industry forecasts
State government databases — Incentive programs, net metering policies, and permitting requirements

All calculator outputs include a stated accuracy margin (±10%) and a disclaimer encouraging users to consult qualified professionals for site-specific assessments. We periodically update our data inputs and methodology; each page displays its most recent revision date.

Editorial Independence

PVSize maintains full editorial independence. While we accept advertising and may earn commissions through affiliate links, our product recommendations and analysis are never influenced by commercial relationships. For full details, see our Editorial Policy.

    Important: PVSize is not a licensed solar installer, electrical contractor, or professional engineering firm. Our content is for informational and educational purposes only. Always consult a qualified professional for site-specific solar installation advice.
