Microinverters represent the latest technology in solar inverters. They are installed on the back of each solar panel and convert DC to AC on the spot. This minimizes the impact of shading on individual panels and allows for easy expansion of the solar system. Microinverters also enable panel-level monitoring but are the most expensive option and can be more challenging to repair or replace​​.

Power optimizers are located on the back of each solar panel and work alongside a string inverter. They condition the DC electricity from each panel before it's converted to AC by the string inverter. These optimizers reduce the impact of shading on individual panels and allow for both panel-level and system-level monitoring. However, they are more expensive than string inverters and may require additional maintenance​​.

String inverters, the oldest and most common type, are reliable and cost-effective. They connect a string of solar panels to a single inverter. However, they are less efficient in optimizing solar energy output, particularly in shaded conditions, and only offer total-system monitoring, not panel-level monitoring​​.

Homeowners can choose from three main types of solar inverters: string (or central) inverters, power optimizers + inverter, and microinverters. Each type has its unique advantages and disadvantages, making it important to understand these before selecting the right one for your solar panel system​​.

Solar inverters play a crucial role in converting the direct current (DC) electricity produced by solar panels into alternating current (AC) electricity, which is the form used by most homes. This conversion is essential for the electricity generated by solar panels to be usable for household appliances and fixtures​​.

The cost of solar batteries varies based on size, brand, and model. It's essential to compare different options to find one that fits your budget and energy needs​​.

This depends on the type of battery you choose. Some batteries offer blackout protection, powering your home when the grid goes down. It's important to check for this feature when selecting a battery​​.

The storage capacity of batteries is measured in kilowatt-hours (kWh). One kWh equals one hour of electricity used at a power of 1kW. The capacity you need depends on your electricity usage patterns​​.

A solar battery's life cycle, or cycle life-time, is the number of times it can be fully charged and discharged, which is considered one full cycle​​.

Depth of Discharge (DoD) refers to the percentage of the battery's capacity that has been used. For example, if a 15kWh battery is discharged by 13.5kWh, its DoD is about 90%. Manufacturers usually recommend a specific DoD to ensure optimal battery performance and longevity​​.

Solar batteries offer several benefits: they reduce reliance on the grid, make the most of your solar system by storing excess energy, provide power during blackouts, and protect against rising electricity prices​​.

Yes, you can add a battery to your existing solar power system, known as a battery retrofit. The feasibility and cost depend on factors like your home's power supply (single-phase or three-phase), the size of your solar power system and inverter, and a check of your switchboard for solar excess​​.

Battery storage is increasingly popular in Australia, especially for those looking to go off-grid. Batteries store electricity generated by your solar power system for use when there's no sunshine. For a battery to be effective, your solar system must generate more energy than you use during the day​​.

The main difference lies in the number of wires and phases used to transmit electrical energy.

The choice depends on budget, electrical setup, and charging requirements, and it's recommended to contact the company for tailored advice.

Yes, comprehensive solutions including EV chargers, solar arrays, inverters, and battery systems are available.

Electric vehicles are generally considered safe and have undergone extensive safety testing.

Yes, EV chargers can be integrated with solar energy systems for optimal charging using renewable energy.

Heat pumps offer lower energy bills, reduced greenhouse gas emissions, and are suitable for homes without the need for solar panels or complex installation.

Heat pumps use a refrigerant chemical, similar to home fridges and air conditioning, to draw in hot air and rapidly heat water. They can also provide energy-efficient cooling.

A heat pump extracts heat from the environment to heat a refrigerant chemical, requiring only a small amount of electricity for operation. It works without solar panels and is efficient in various temperatures.

Costs vary based on size, brand, installation requirements, and rebates. Prices range from $500 to $3000 for typical replacements.

The process is handled by the company, with rebates available for replacing various systems. More environmentally friendly replacements offer higher benefits.

Heat pumps, using less power, can effectively run with excess power from home solar electricity systems. Custom solutions can be designed for optimal efficiency.

Heat pumps use refrigerant to absorb heat from the air, even on cold days, and compress it to heat water. This is more energy-efficient compared to traditional electric or solar hot water heaters.

This NSW government initiative offers interest-free loans for solar battery systems, up to $14,000 repayable over eight years for new setups, or $9,000 for retrofitting existing solar panel systems, repayable over ten years. Eligibility includes being an NSW resident with an annual household income of no more than $180,000​​.

While there is no specific battery rebate in NSW, other incentives include household energy saving upgrades, EV purchase stamp duty saving, and the "Empowering Homes – Solar Battery Loan Program," which offers interest-free loans for solar battery systems​​.

The Federal STC solar rebate program issues Small-scale Technology Certificates based on the solar system's size and the resident's postcode. For instance, the rebate on a 6.6kW solar system in 2023 amounts to approximately $2,844, saving about 29% off the installation cost. The rebate varies based on the STC trading price and installation timing​​.

Homeowners are compensated for excess electricity generated by their solar systems and fed into the supply grid. The current feed-in tariff in NSW is 7.6 cents per kWh, and rates can vary, so it's advisable to shop around for the best rate​​.

The Small-Scale Renewable Energy Scheme under the Australian Government's Renewable Energy Target (RET) allows homeowners to create STCs for every megawatt hour of power generated. These STCs are purchased by electricity retailers and can significantly reduce the cost of solar system installation. Eligibility criteria include using approved components and installers and adhering to safety standards​​.

Eligible low-income households in NSW may receive a free 3-kilowatt solar system installation. This program aims to reduce electricity bills, with potential savings of up to $600 a year​​.
