Frequently Asked Questions - Evacuated Tubes Neopower

How does an evacuated tube solar collector work?

Evacuated tubes use a vacuum between two glass layers to minimize heat loss. The inner tube has a selective coating that absorbs solar radiation, heating a heat pipe or circulating fluid inside the tube.

What is the recommended tilt angle for installation?

For optimal performance, the collector should be tilted at an angle equal to your latitude, typically between 30° and 60°. Adjust for seasonal use.

Can the system provide hot water on cloudy days?

Yes, but with reduced efficiency. Evacuated tubes can still absorb diffuse solar radiation, but a backup heater (e.g., electric or gas) is recommended for continuous supply.

How long do the evacuated tubes last?

With proper maintenance, the tubes can last 15–20 years. The selective coating degrades slowly, but efficiency remains high for at least 10–15 years.

What maintenance is required?

Clean the tubes annually with water and a soft cloth to remove dust. Check seals and insulation for damage. Replace any broken tubes immediately.

Can I install the system myself?

While possible, professional installation is recommended to ensure proper plumbing connections, roof sealing, and compliance with local building codes.

What happens if a tube breaks?

The system will still operate but with reduced efficiency. Replace the broken tube as soon as possible. A replacement tube can be ordered from Neopower.

Does the system work in freezing climates?

Yes, if properly installed with a glycol-based antifreeze or a drainback system. The vacuum insulation prevents heat loss even in sub-zero temperatures.

How much space is needed for the collector?

For a standard 2.5 m² collector, allow about 3 m x 2 m of unshaded roof area with a maximum of 5% shading between 9 AM and 3 PM.

What is the typical water temperature output?

On a sunny day, the water can reach 60°C to 80°C (140°F to 176°F). Use a mixing valve to prevent scalding.

WHAT ARE NEOPOWER CUSTOMERS SAYING..?

GREAT PRODUCT! AWESOME SERVICE!

From initial consultation, through to installation, the service provided by Neopower has been great. We are located in Melbourne and the Neopower Solar Hot Water system is well suited to our family of four. Have turned on the booster mid April. Very happy with our purchase.

SHOULD HAVE DONE IT EARLIER

This electric solar hot water system has been in use for just over a year. Since that time we have used our booster for around one month during a real cold spell in winter. It has saved us a fortune (we had a gas hot water heater before). One regret is that we did not install it earlier.

IN WITH THE NEW

\*EFFECTIVE AUGUST 2019 5 STAR AVERAGE - SIX YEARS RUNNING

When my old electric hot water system started leaking I decided to investigate hot water systems and after months of research I decided on a gas boosted solar hot water system using evacuated tubes. Neopower seemed to be offering the best quality and price so I went ahead last May 2018. My power bill has dropped by 50% and it is great having a shower knowing it is the sun that is providing the hot water!

Date Purchased May 2018

So far so good the power consumption in the the 1st week is unbelievable, we have gone from using 30 to 40 kwhs a day to under 10. It actually looks better on the roof than most and the price was much better. anytime I needed to know anything from Neopower themselves they have been ever so helpful and the guys we bought and had it fitted by very helpful and nice. Extremely happy customers here.

Date Purchased Nov 2018

QUALITY SYSTEM AND GOOD PRICE

I decided to give it a try because the sales person gave me a quite attractive price. Installer was very helpful in explaining everything, and when I asked him about Neopower system, he said it's a quite reliable system. All went well after I decided to purchase their system. Now it has been 8 months and I am very happy with my current electricity bills.

Date Purchased Ari 2016

As such they offer me a price for supply & installation of a new SHW system - 250L Gas Boosted SHW with 25 Evacuated Tubes & Rinnai s20 gas booster, and would also take care of the rebate paperwork. I am writing this now as I have had the system nearly 2-years and it's fantastic, hardly any boosting required.

HOW EVACUATED TUBES WORK.

1 The coating on the inner tube converts sunlight into heat.
② Heat is transferred to sealed copper “heat pipes” containing liquid. The liquid is heated and forms a vapour which rises to the condenser.
③ Water is heated as it passes through the condenser.

ADVANTAGES

CYLINDRICAL COLLECTOR CAPTURES ENERGY FROM SUNRISE THROUGH TO SUNDOWN.

NO CONVECTIVE OR CONDUCTIVE HEAT LOSS.

LONGER LASTING / INDUSTRY LEADING WARRANTY.

DURABLE 2.5MM GLASS STRENGTHENED WITH BOROSILICATE.

HOW THE SYSTEM WORKS.

1 Cold water is pumped through the condenser in the collector.
② Heated water returns to the tank, and is stored for later use.
3 A gas or electric booster ensures the water is delivered to the home at a usable temperature, even during Winter.

ADVANTAGES

HASSLE FREE HOT WATER.

SAVE UP TO 80% ON GAS OR ELECTRICITY.
