Everything you need to know about going solar with Impressive Electrical & Solar.

Solar Installation

How long does a solar installation take?

Most residential solar installations are completed in one day. Commercial systems may take 2–3 days depending on system size and roof complexity.

How do I know what size system I need?

We size your system based on your actual electricity bills, not guesswork. We'll analyse your usage patterns and roof orientation to recommend the most cost-effective system — typically 6.6kW to 13.2kW for Sydney households.

Do you use subcontractors?

No. Our installation team are all direct employees — licensed electricians who are SAA accredited. This means consistent quality and full accountability on every job.

What brands of solar panels and inverters do you use?

We only install Tier 1 panels (Jinko, Aiko) and premium inverters (Goodwe, Sigenergy, Sungrow). We do not compromise on equipment quality.

What warranty do I get?

You receive a 5-year workmanship warranty from us, plus manufacturer warranties — typically 10–12 years product warranty and 25 years performance warranty on panels, and 5–10 years on inverters.

Rebates & Costs

What government rebates are available?

The Australian Government's Small-scale Technology Certificate (STC) scheme provides an upfront discount depending on system size and location. We calculate and apply this rebate automatically — no paperwork required from you.

How quickly will solar pay itself off?

Payback period varies depending on your usage, system size, and how much electricity you consume during daylight hours. With current NSW electricity rates, most households see a strong return on investment within a few years. Contact us for a free assessment tailored to your situation.

Battery Storage

Do I need a battery?

A battery is not essential, but it significantly increases your self-consumption of solar. If you're mostly home during the day, a battery may have limited return. If you use most power in the evenings, a home battery can dramatically reduce your bills.

Which batteries do you install?

We install Sigenergy and ESY batteries — two of the most trusted brands in Australia. Both come with strong manufacturer warranties and established local support.

After Installation

How do I monitor my system?

We set up monitoring for you during installation. Depending on your inverter brand, you'll have access to a mobile app (e.g. Fronius Solar.web, SolarEdge app, or Enphase Enlighten) showing real-time generation and consumption data.

What should I do if my system stops working?

Check your inverter display for any fault codes first. Then submit a support ticket via our Support page or call us directly on 1300 797 630. We service all brands, not just systems we installed.

Do you service solar systems you did not install?

Yes. We repair and maintain all brands of solar systems across Greater Sydney — including inverter replacements, panel replacements, and fault diagnosis.

Service Area

What areas do you service?

We service all of Greater Sydney, including the Sutherland Shire, Inner West, Eastern Suburbs, Hills District, Western Sydney, and the Illawarra. Based in Miranda, we can typically reach most Sydney suburbs within the same day.
