Planning estimates
Calculators, guides and saved plans provide preliminary planning information. They are not a final electrical design, security design, structural assessment, bill of quantities, guaranteed energy yield or professional certification.
Site verification is required
Before equipment is purchased or installed, a competent professional must verify actual nameplate loads, startup current, supply phase, wiring, earthing, protection, roof condition, shading, cable routes, network conditions and applicable safety requirements.
Your inputs
Results depend on the information you provide and on editable assumptions. You are responsible for checking quantities, usage hours, prices and property details. Product availability, tariffs, fuel prices, warranty terms and solar resource can change.
Quotations and installation
An online result is not a quotation. Any supply, installation or maintenance work requires a separate written scope, price, schedule, warranty and payment terms accepted by the relevant parties.
Acceptable use
Do not attempt to disrupt the site, access private administration features, submit unlawful material or use automated traffic in a way that degrades service for others.
Updates
We may improve the calculators, content and these terms as the service develops. The date above shows the latest published revision. If you do not agree with these terms, do not rely on the tools for a purchase or installation decision.
