Choose a solar installer with confidence
The panels are only one part of the job. A sound design, compliant installation and responsive after-care matter just as much as the equipment on the roof.
It starts with your home, not a sales catalogue
A reliable solar system is designed around how you use electricity. The installer should understand your monthly bills, the appliances you need during an outage, your roof, your distribution board and the local rules that apply to the property. Only then can the inverter, battery and panels be sized sensibly.
A proper project normally includes a load assessment, system design, an equipment schedule, a clear quote, mounting and electrical work, commissioning, monitoring setup and the compliance documents you need to keep for your insurer and municipality. The cheapest quote is not necessarily the lowest-cost system if it leaves you with poor backup, weak warranties or an installer who disappears after payment.
Use this installer checklist
- Ask for the exact inverter, battery and panel models.
- Check what backup circuits the design actually supports.
- Confirm workmanship, product and battery warranty terms.
- Ask who handles faults, monitoring and after-sales support.
- Confirm the installation and electrical compliance paperwork.
- Compare total cost, escalation and ownership—not just month one.
Compare the way you want to pay
SolarGuide is independent of the installation teams. We can route a quote enquiry to Alumo, which offers outright purchase, rent-to-own and subscription options, or to Wetility, whose core offer is a managed solar subscription. Both routes still need a proper assessment and final design. A monthly figure without the system size, term, escalation, ownership and included services is not enough to compare fairly.
Alumo
A useful starting point if you want to compare rent-to-own, subscription and outright purchase. Alumo supplies, installs and supports the system, subject to assessment and approval.
Wetility
Worth considering if a low-upfront, managed subscription is your priority. Confirm the qualifying system, term, installation scope and current offer directly in the quote process.
