Frequently Asked Questions

Yes, it will work on cloudy days, although not as efficiently as in sunny weather.

It is normal practice to leave the electrical or gas backup heater on so that in bad weather the system automatically maintains the hot water. Our solar controllers have a backup heating option, making backup heating fully autonomous .

Water heating normally takes between 40 and 60% of the average power bill. Savings depend on the current energy rates, the amount of hot water used and the amount of water your heating. Your HWC can act as a "hot water battery" as energy can be stored in the form of hot water and used over a few days if sized correctly. During the summer months, very little to no power is required for water heating. It's only when we experience prolonged periods of rain or cloudy weather that backup heating is required. Heating your pool and spa with solar can further reduce your power bill.

Yes it will add value to your home, and also provides an investment in the New Zealand environment.

This depends on the number of people in your household and the size of your hot water cylinder. Our aim is to ensure that your solar system meets the needs of your family.

Here are some rough guidelines:

• 1-2 adults with a 135-150 litre hot water cylinder require a 1 standard size (2.00 sqm) panel system.

• 2-3 adults with a 180-200 litre hot water cylinder require a 1 large size (2.5 sqm) panel system.

• 3-4 adults with a 220-300 litre hot water cylinder require a 2 standard size panel system.

• 5-6 adults with a 300-500 litre hot water cylinder require a 2 large size panel system.

Yes. The panels are modular and designed for easy add-ons.

Yes, the system complements both new and existing homes.

Both.

Preferably on a north-facing roof as close as possible to the hot water cylinder. The second choice is facing the afternoon sun (north-west). The third choice is facing the morning sun (north-east). Never facing south. The panels can tolerate a large variation off north with little loss in efficiency.

Normally installations take 1 day.

Stylish European design, superior performance, ECO friendly, and can be connected into existing hot water systems.

10 years on the panels and manufacturer's warranty on other components.

Systems typically last more than 10 years. The heating fluid runs through copper, a metal known for its longevity, providing good potable water.

Occasional cleaning of the glass cover helps maintain efficiency.

In pure efficiency terms, solar-thermal or solar hot water heating panels are over three times more efficient at harvesting energy than solar-electric (PV) panels. This does depend on what you want. If you have a lot of hot water to heat up, this is the way to go. Buildings in New Zealand are exposed annually to 20 or 30 times more energy from the sun than they consume in electricity and gas. New Zealand has a world class solar resource.
