How Do Solar Panels Work?

Solar panels capture sunlight and convert it into electricity through their solar cells. This energy then passes through an inverter, turning it into usable power for your home or business. Any excess can be stored in a battery or exported back to the grid.

From start to finish extremely happy with the solar set up we have. Looking forward to those long summer days now knowing that we are producing our own electricity.

 Trustindex verifies that the original source of the review is Google. We are very happy with our system design and install.  Throughout the entire process communication was great and everything explained thoroughly.  Special mention to the install team who endured possibly the 2 coldest days of the year on our roof! The ongoing support available post install with meter changes and app help was a key in choosing eco-efficient and has been excellent.

 Trustindex verifies that the original source of the review is Google. Deciding on solar is a process that brings up numerous options, jargon and technicalities that can quickly become confusing. Shaun at Ecoefficient solutions guided us through the process of choosing a system that suited us, vs simply achieving a sale. Shaun’s knowledge, expertise and common-sense approach as well as his patience with our questions provided us confidence and the communication throughout the install process was excellent. The install team were friendly, tidy and treated our install as though it was their own house. Very happy with the results and the system and have great confidence in knowing the service continues past the system being completed.

After shopping around, we found Shaun and the team from Ecoefficient to be excellent to engage with and provide a comprehensive solution to meet all our requirements.

When it came to the install, Shaun was great at problem solving some changes we needed to make to our meter box, and extremely accomodating with a last minute request for an EV charger to be added to the mix.

The work completed by the installation crew is excellent, an extremely tidy and high quality install and set up, which we’re really happy with. Sam was great to deal with when it came to the installation day!

Comms and post install support has also been great - the team kept us updated throughout the process and made everything seamless for us as a customer.

With banks offering sustainability loan products and rates, it’s a great opportunity to unlock some cost efficiency and resilience and with a company like Ecoefficient you can’t go wrong! Thanks to Shaun and the team for a great experience and product!

Home Solar & Battery Frequently Asked Questions

Getting Started With Solar

Why should I go solar?

The main reasons are to reduce your power-bill, have power in an outage, add value to your home all whilst reducing your carbon footprint.

How much does solar and batteries cost for an average home?

This varies significantly, anywhere from $10,000-$35,000 for an average home

How many panels do I need?

This varies for each property, but an average residential home needs around 12x panels without a battery and 18x panels with a battery.

Do I need a solar battery?

You don’t need a battery in order for your solar system to function and to save you money. However, a battery does save you more money on your power-bill and it gives your home power in an outage. Most homes will benefit from an 8-16kWh battery system – it all depends on the budget available for you to invest.

Can I add more panels or batteries later on?

Definitely, we can design the system so that you can easily extend down the track.

Will solar help save me money?

Yes, we aim to reduce your power bill by around 40-50% with solar alone, or up to 90% with solar and a battery. We cannot guarantee this saving, as it all depends on your power usage and habits.

Installation Process

How long does it take for your team to install?

Around 1-3 days on average.

Do we need lines consent and will you organise this?

Yes, you will need lines consent as part of our installation process we handle everything for you start to finish!

How does the power get exported to the grid?

You require an import/export meter which your power company will provide for you. This counts the amount of power that you will import/export. The exported power is credited to you on your power bill. In New Zealand, this is the ‘on-grid’ compliance requirement.

How much do I get paid for exported power?

This varies for each person, but the average is 12-15c per kWh currently, however new legislation mid-2026 will require power companies to pay much more back to their customers during peak export times.

Product Lifespan & Quality

How long do panels last for?

Our panels come with a 30-year performance warranty. At 30 years they are still producing at over 80% of their original efficiency, so their life expectancy could be 40 years or more. Most of our inverters and batteries come with a 10-year warranty and their life expectancy is around 15 years.

What does a battery actually do?

Yes, you will need lines consent as part of our installation process we handle everything for you start to finish!

How much does a battery cost?

We only install premium lithium-ion batteries, each backed by a 10-year warranty. Our most popular choice among customers is the SigEnergy modular battery, which comes in a variety of sizes to suit different households and energy requirements. We also offer the Tesla Powerwall 3, providing 13.5kWh of storage and a strong option for many homes.

Performance & Monitoring

How do I monitor my solar system?

We ensure that every system comes with some form of app based monitoring, so we will talk to you about which option is best for your system.

Do your solar panels heat hot water?

Short answer, yes. However, we do not provide or recommend solar hot water tubes/panels. Heating water directly on your roof is now considered old technology. There is a large amount of maintenance required for solar hot water and in winter it sometimes leaves you with cold water. We provide solar panels that produce electricity, and we divert that electricity to your hot water cylinder. This then powers the element within your cylinder, meaning that your hot water is now powered by solar power.

What happens when the power goes out?

If you have a solar battery through us, then your essential appliances in your home will work in a power outage if that is what we have designed. If you don’t have a solar battery, then your solar system will turn off and you will be in an outage like everyone else.

Future Expansion

Can I add a battery later?

Of course, if you’d like to add a battery in the future, we can discuss your options and ensure your system is set up correctly for the option in the future.

Can I extend my system in future?

Yes. You can easily add more solar panels and batteries in the future as your energy needs change.
