About Energy Made Clear

Energy Made Clear is a free home energy toolkit created by Zhang Guangpeng (张光鹏). The project draws on a background in digital energy software and a practical interest in making electricity, solar, batteries and electric vehicle charging easier to understand.

The site is written for English-speaking households, including readers in Europe and North America. It does not assume a country-specific tariff: bring your own energy prices and equipment details.

What you can expect

Simple tools, visible formulas and clear limits. These are first-pass estimates for exploring a question, not quotations or engineered system designs.

Independent by design

This is a personal project. It is not an official website of an employer, equipment manufacturer or utility. No customer case studies or commercial performance claims are presented.
