We get the challenges solar & renewable energy installers face

Muster was built with input from solar & renewable energy installers like you. Here's how we solve your biggest headaches.

MCS certification tracking

Government grants require MCS certification. Track every installer's qualifications and scheme renewals.

Complex installations

Solar, battery, inverter, DNO notification — every install has multiple stages. Muster tracks them all.

Post-install maintenance

Panel cleaning, inverter checks, and performance monitoring. Build recurring revenue from your install base.

Grant and rebate paperwork

Smart Export Guarantee, ECO4, and BUS grants all need documentation. Keep it all in the job record.

Features that make a difference

Every feature designed with solar & renewable energy installers in mind.

MCS Compliance Hub

Track MCS registration, RECC membership, and installer qualifications. Alerts before expiry.

Multi-Stage Projects

Track each install through survey, design, DNO application, installation, commissioning, and handover.

Grant Documentation

Attach SEG, ECO4, and BUS documentation to jobs. Everything the customer and grant body needs.

Maintenance Revenue

Schedule annual panel inspections and inverter checks. Automated reminders keep customers coming back.

Installation Evidence

Before, during, and after photos. Roof surveys, panel layouts, and commissioning records.

Staged Payments

Collect deposit, post-install balance, and maintenance fees. Customers pay online.

"MCS audits used to stress us out. Now every install has full documentation — photos, certs, DNO confirmations — all in one place."
