What we make clear
Understand the implication before you commit.
We separate indicative guidance from confirmed proposal facts, so you always know what is known, what is assumed and what comes next.
01
Package fit
We recommend a starting system from your spend or usage. You are not expected to select technical components.
02
Potential savings
A range is shown with assumptions. A personalised OpenSolar proposal confirms production and savings later.
03
Ownership
Cash systems are owned after full payment. Financed ownership after the final payment is confirmed in the agreement.
04
Approval
An enquiry is not a credit application. Any credit check happens only after explanation and explicit consent.
Finance is subject to credit approval.
