What is an off-grid solar power system comprised of?

An off-grid solar system is designed to operate independently of the traditional utility grid. This means your home or business relies entirely on solar panels, batteries, and a backup generator to meet all your electricity needs.

Solar Panels and Energy Generation - Off-grid systems use high-efficiency photovoltaic solar panels to generate electricity during the day. These panels harness sunlight, converting it into energy that powers your immediate needs and charges the battery storage system.

Battery Storage - A critical component of any off-grid solar system is a large battery bank that stores excess energy generated during the day. This stored energy is essential for powering your home during periods of high demand or when solar production is low, such as at night or during extended cloudy weather.

Backup Generator - To ensure uninterrupted power, especially during prolonged periods of poor weather, a backup generator is often recommended. This generator provides an additional layer of security, ensuring your energy supply remains steady even when solar and battery resources are low.

Embracing an eco-friendly lifestyle and adapting to living off solar power


Living off-grid requires careful planning and adaptation. Efficient power use, especially during low solar production or nighttime, is crucial, and large battery banks are essential. Lifestyle adjustments, such as maximising power use during daylight hours, may be necessary, and having a back-up generator might be unavoidable. Also, you can't sell excess energy back to the grid.

However there are advantages that an off-grid solar system offer including eliminating worries about power grid outages, rising electricity costs, and unpredictable energy bills. By choosing solar energy, you significantly reduce your carbon footprint and contribute to a more sustainable, eco-friendly lifestyle, preserving New Zealand's natural beauty.

FAQs about off-grid solar power systems

The number of panels depends on your energy consumption, location, and the amount of sunlight your area receives. Coastal Power offers a professional assessment to determine the exact number required.

Yes! As long as you have sunshine.

Answer  here

It depends on whether continuous power is important to you. If there are extended periods of cloud then your batteries may not be enough to sustain power through this time. We can discuss the options with you.
