When sunlight hits the solar panels, the PV (photovoltaic) cells convert it into DC (direct current) electricity.

An inverter (included with your system) then changes this DC into AC (alternating current) power—the type your home appliances use.

Your appliances will run on this solar power first. If more energy is needed, the extra will come from the electricity grid.

Any surplus solar energy can be stored in a battery for use at night or sent back to the grid.

Simple as that.

The cost of a solar system depends on several factors, including the system size, the type of panels, the inverter, and whether a battery is included.

• New Zealand: On average, a residential solar system costs around $10,000 without a battery and about $16,500 with a battery.

• Fiji: On average, a residential solar system costs around $15,000 without a battery and about $25,000 with a battery.

When your solar system generates more power than your home is using, the extra energy is first stored in your home battery. Once the battery is fully charged, any remaining excess is sent back to the electricity grid.

When your home needs more energy than the solar system is producing, your battery supplies the difference by discharging stored power.

Most residential systems are installed within 1–2 days, while commercial projects may take longer depending on size and complexity.

A Solar Green Loan is a bank loan created specifically to help homeowners purchase and install solar panels. These loans usually offer lower interest rates and more flexible repayment terms compared to standard loans, making them a cost-effective way to switch to solar energy.

Solar systems are very low-maintenance. The main upkeep is a simple panel clean once a year to keep them performing at their best. Over time, you may also need to replace the inverter, typically every 10–15 years.
