Description: Custom theme for Royal Power, South African solar PV and battery storage EPC (Kelvin, Sandton). The home page opens with the lights off and a wall switch to turn the site on; a lights switch in the header flips the whole site between light and dark. Interactive "a day on solar" energy-flow simulator with load shedding, savings calculator, credentials as a DB board, case-study projects (old URLs kept), three-step free feasibility form with bill uploads saved as Leads with statuses, contact form, styled WooCommerce backup-power shop with cart drawer, POPIA policy drafts, Elementor / Elementor Pro compatible, automatic page set-up on activation that keeps the old site's URLs.
