A little sunshine. A decision that fits everyday life.
Solar Sizer is an independent information and calculator project operated by Rhys, an individual publisher based in mainland China. It helps you separate the value of a small solar setup from the extra value of a battery.
What you will find here
The calculator makes its assumptions visible. The blog takes you from first questions and preparation to observing a system you already own. Sources, worked examples and model boundaries stay alongside the advice.
A good decision can be “not yet”
No battery is a valid comparison. We do not promise savings, approve an installation or certify a product. A site-specific technical or legal question needs the appropriate professional assessment.
How the work is prepared
Content may be prepared with AI-assisted drafting. Linked primary sources and published model assumptions provide its basis. We do not claim personal product testing, professional qualifications, home inspections or independent expert review unless these are explicitly documented.
