How to choose solar energy services

Understand solar energy services scope, compare proposals and prepare a brief before contacting providers.

Define the scope

A solar proposal should be based on your consumption, site conditions and the purpose of the system. Equipment capacity alone does not describe expected performance. Ask the installer to document assumptions, system design, support and the responsibilities for electrical work and any required approvals.

What to compare between providers

  • Compare the same load assumptions and identify the equipment models quoted.
  • Ask about installation, protection, monitoring and maintenance responsibilities.
  • Read warranty coverage, exclusions and the process for obtaining service.

Prepare a useful request for a quote

  • Share consumption records and the loads you need to support.
  • Provide site details, roof access and available system documentation.
  • Request an assessment and a written explanation of the proposal's assumptions.
