For a typical New Zealand home using around 8,000 kWh per year, you might need between 10 to 20 solar panels to cover your electricity needs.. For a typical New Zealand home using around 8,000 kWh per year, you might need between 10 to 20 solar panels to cover your electricity needs.. The average New Zealand home will need 15 to 20 solar panels, but the number really depends on:Your household energy needsHow much of your roof is available for panelsThe quality of the panelsThe kW capacity of your solar panel system.. Solar panel system sizes suitable for New Zealand homes normally range between 3 kW (9 solar panels) and 8kW (20 solar panels).. It comes down to the capacity of the system you choose to install, and the quality of the panels, but the average New Zealand household will need 15-20 solar panels to power their home. [pdf]
The larger 8kW, which is roughly 20 solar panels, is more suitable for a power-hungry home - with 5 bedrooms, a spa pool, battery storage, EV charger, etc. However, the statement above is very generalised, and a one-size-fits-all approach usually doesn’t work well when it comes to solar power.
As more homeowners look to reduce their carbon footprint, solar panels are increasing in popularity. In the past year alone, installations have increased 15 per cent and at the end of February there were 31,000 solar power installations across New Zealand.
For households, this would commonly be a System with a maximum output of 5kW, with commercial operations generally requiring Systems of 6kW and over. Check out this guide by Unison NZ to calculate the size of the Solar Panel System your home will need.
A 5kW system is usually comprised of 15-20 panels, so the total rooftop area needed for a 5kW system is around 25-35m2. A 10kW system generally needs 30-40 solar panels, so around 55-70m2 of space. Modern, high quality panels are more efficient, so you will need less of them to run a house.
A household can easily have a self-consumption rate of 60%, i.e using up 60% of the solar power generated. But there will need to be a few adjustments around the home, like timing the use of the washing machine and dishwasher sometime around the middle of the day.
Solar panels are better suited to some situations than others and assessing your property for its suitability is a great place to start. If you use power during the day, have electric hot water, and your roof is in good condition and is north facing, then your home is probably a good candidate for solar power.

Here’s a ballpark range for typical residential solar system installations in Romania (excluding government incentives):Small system (3 kW): €3,000 – €5,000 (US$3,300 – US$5,500)Medium system (5 kW): €5,000 – €8,000 (US$5,500 – US$8,800)Large system (8 kW): €8,000 – €12,000 (US$8,800 – US$13,200). Here’s a ballpark range for typical residential solar system installations in Romania (excluding government incentives):Small system (3 kW): €3,000 – €5,000 (US$3,300 – US$5,500)Medium system (5 kW): €5,000 – €8,000 (US$5,500 – US$8,800)Large system (8 kW): €8,000 – €12,000 (US$8,800 – US$13,200). Romania is set to subsidize households with EUR 610 million for installing solar power panels or four times more than last year. [pdf]
Romania is undergoing a significant expansion in solar power within its broader energy transition framework, bolstered by European funding and legal reforms.
Romania has set an ambitious target to install over 8 Gigawatts of solar energy capacity by 2030, which is anticipated to constitute 24% of its gross final electricity consumption from renewable sources.
Overview of solar PV developments Following a period of lull, Romania has achieved in 2023 a significant milestone in its renewable energy journey – over 1 GW of new solar capacity installed in one year between distributed generation and utility scale projects.
The Romanian market has a good chance to add more cumulative installed PV capacity in the next 2 years, especially under net metering and self-consumption commercial and residential installations. The report provides a complete picture of the market situation, dynamics, current issues and future prospects.
Notably, a substantial private investment is set to establish the largest photovoltaic park in Europe in Arad, boasting a capacity of 1000 megawatts across 100 hectares, indicative of Romania’s commitment to expanding its renewable energy infrastructure.
This initiative aims to bolster EU states’ energy savings, clean energy production, and supply diversification. Romania is set to benefit significantly from REPowerEU, with an allocation of 1.4 billion Euros to hasten the green transition and foster renewable energy investments.
