A tool for preparing your decision.
Solar Sizer is operated by Rhys, an individual publisher based in mainland China. Contact: ascetic0603@gmail.com. These notes describe website use; they do not provide individualized electrical, legal or tax advice.
Calculations and guidance
Results depend on your inputs, simplified load profiles and published weather references. They do not guarantee production, savings or financial performance. Weather, tariffs, equipment, aging and actual use may differ.
The current model compares DC-coupled batteries sharing one AC output cap. It is not a design tool for every AC battery, backup-power system or time-of-use tariff. Read the method and boundaries.
No installation approval
Check current rules, manufacturer documents, your site and required permissions. Qualified professionals should assess specific electrical and structural questions. Do not rely on a web page or email response to address a dangerous condition.
External offers and content
Other providers are responsible for their prices, contracts and services. A link does not guarantee ongoing availability or compatibility. The rights of source publishers and photographers remain with them; sources and image credits are identified.
Fair use and corrections
Use the tool without disrupting other visitors or the service. When sharing results, include inputs, date and model limitations so an estimate is not mistaken for a guarantee. Report suspected errors through the contact page.
Your legal rights
These notes do not seek to remove mandatory rights or liability that applicable law does not allow to be excluded. The rules applicable to the particular circumstances still govern.
