Expert off-grid solar solutions by SQ1i Ltd.

Welcome to SQ1i Ltd, where we specialise in providing top-quality off-grid solar systems tailored for the UK’s unique climate. Our expert team commits to delivering sustainable, reliable, and cost-effective solar solutions.

An off-grid solar system allows you to produce your own electricity and live independently from the power grid. It’s ideal for remote or rural areas where grid connections are not available, as well as for anyone looking for a reliable and sustainable source of power.

Why Choose Off-Grid Solar?

An off-grid solar system, also known as a standalone solar system, is a self-sufficient system that generates electricity from solar panels and stores it in batteries for later use.

Benefits of Off-Grid Living
