  Choosing the right solar system size is one of the most important decisions you’ll make when going solar. Go too small and you’ll barely scratch your electricity bill. Go too large and you’ll be exporting cheap energy to the grid while paying off panels you didn’t need. For most Sydney homeowners, the real decision comes down to two options: a  6.6kW system  or a  10kW system . Both are popular, both are well-suited to Australian conditions but they serve very different households. If you’re exploring  residential solar options in Sydney , this guide will break down everything you need to know to make the right call in 2026. We’ll cover daily output, costs, payback periods, and exactly which type of household each system is best for. Quick Overview: 6.6kW vs 10kW at a Glance Feature 6.6kW System 10kW System Daily Energy Output ~25–27 kWh ~38–42 kWh Number of Panels 12–15 panels 18–22 panels Roof Space Required ~30 m² ~45–48 m² Cost After STC Rebate $5,000–$8,0...

  If you’ve seen claims that the solar battery rebate is ending in 2026, the reality is more nuanced. The federal incentive supporting home battery systems in Australia   is not ending in 2026 , but it   will change from 1 May 2026 . The adjustment affects how the rebate is calculated, which means some installations may receive a slightly smaller discount than earlier in the year. Understanding these changes can help homeowners decide whether installing a solar battery sooner rather than later makes financial sense. Below is a clear breakdown of how the rebate works, what changes in 2026, and what it means for households considering solar battery storage. What Is the Solar Battery Rebate in Australia? Australia’s federal battery incentive is delivered through the  Cheaper Home Batteries Program , designed to encourage households and businesses to install energy storage alongside rooftop solar systems. The program does not operate as a cash payment. Instead, it works ...

  Integrating air conditioning with solar power is one of the most practical ways Australian households can cut electricity bills while staying comfortable year-round. With air conditioners often being the biggest energy users in a home, pairing them correctly with a solar system allows you to run cooling and heating using power generated on your own roof instead of relying on the grid. This guide explains how solar and air conditioning work together, the best system setups for Australian conditions, and what to consider before installation. Why Air Conditioning and Solar Are a Natural Fit Air conditioners consume the most electricity during the day, particularly in summer. This happens to align perfectly with peak solar generation hours. When solar panels are producing power: Your air conditioner can run directly on solar energy Less electricity is drawn from the grid Exported solar energy can be reduced or avoided Energy bills drop immediately In many Australian homes, cooling ac...

  Battery storage is becoming a practical upgrade for Australian households looking to reduce grid reliance and manage rising electricity costs. The Tesla Powerwall is one of the most widely recognised home batteries, but confusion often surrounds the   Tesla Powerwall rebate   — particularly how much it is worth, when it applies, and who qualifies. This guide explains the Tesla Powerwall rebate in clear terms, including  rebate amounts, eligible models, key dates, and eligibility requirements , with guidance for homeowners considering installation through  Greenlight Solar . Is there a Tesla Powerwall rebate in Australia? Yes, but it is  not a general cash rebate offered year-round  and it is  not unlimited . The Tesla Powerwall rebate is a  time-limited promotional incentive  available on specific Powerwall models when ordered and installed through a  Tesla Certified Installer , such as Greenlight Solar. This rebate is separate fr...
