How Solar Helps Reduce Household Budgets

It's no secret that household budgets are tighter than ever. With inflation and other economic factors causing living costs to increase, families and businesses alike are looking for ways to reduce their expenses. Solar energy is one of the most effective tools available for reducing costs in the long term.

Electricity: A Major Household Expense

For most New Zealand households, electricity is one of the largest recurring expenses after housing and food. The average New Zealand household spends $1,500–$2,500 per year on electricity, and this has been rising steadily.

With electricity tariffs increasing significantly in recent years, many families are finding their energy bills have become a significant financial burden — particularly in regions with hot summers driving heavy air conditioning use.

How Solar Directly Reduces Your Electricity Bill

When you install solar panels, you generate your own electricity from sunlight. Every unit of electricity your system generates is one less unit you buy from the grid. At typical electricity prices of 30–40 cents per kWh, each kilowatt-hour you generate yourself represents real savings.

A quality 6.6kW solar system in New Zealand or NSW generates approximately 25–30 kWh per day on average. At current electricity prices, this represents $7.50–$12 of daily savings — or $2,700–$4,380 per year.

Real Numbers: Before and After Solar

A typical EFS Solar customer in New Zealand before solar:

Quarterly electricity bill: $500–$700
Annual electricity cost: $2,000–$2,800

After installing a 6.6kW solar system:

Quarterly electricity bill: $100–$200 (import charges only)
Annual electricity cost: $400–$800
Annual saving: $1,200–$2,400

The Long-Term Budget Impact

Over the 25-year life of a solar system, the cumulative bill savings can exceed $40,000 — even without accounting for future electricity price increases. With price increases factored in, the savings are even greater.

$0 Upfront: No Budget Impact to Get Started

EFS Solar offers $0 upfront financing, meaning you can start benefiting from solar without any impact on your current budget. In many cases, your monthly loan repayment is less than your monthly electricity bill saving — meaning you're financially ahead from day one.
