Solar Calculator Wordpress Plugin - Rating, Reviews, Demo & Download
Plugin Description
The Solar Calculator is a user-friendly WordPress plugin that helps homeowners, installers, and energy consultants easily calculate the potential
solar power production of a specific location. This plugin lets you calculate the yield, self-sufficiency, and payback time of a photovoltaic
(PV) system directly on your WordPress site.
It includes:
- A clear, responsive frontend calculator
- Customizable backend settings (regional values, cost presets)
- Multilingual support (WPML, Polylang, etc.)
- Realistic solar data for accurate estimations
- Battery and installation cost calculations
- Language-ready template with .po/.mo files (DE, GR, IT, EN, ES, FR)
Ideal for solar companies, energy advisors, or eco-conscious website owners.
A small “HBurk” link inside the calculator refers to the author’s website as a non-intrusive credit.
Made in Germany – optimized for European users.
