Are the solar collectors noticeable on the roof?

They are very thin and can be flush mounted, blending well with roof design. From a distance, they may look like skylights. Check local council restrictions for installation.

Can QIRUI solar collectors be mounted on a flat surface?

Yes, they can be mounted on flat roofs or ground using a stainless steel Flat Roof Frame. Install at a minimum 20-degree angle for optimal heat pipe operation.

Product Q&A

Q:Is solar water heating a viable alternative to gas or electricity?

Solar should be seen as a supplement rather than a total replacement. A correctly sized system can provide 60%-70% of hot water needs annually. It can be automated to guarantee hot water regardless of sunlight levels.

Q:How long will it take to recoup my investment?

For a household spending 25% of its electricity bill on hot water, the full cost may be recouped in 4-5 years through reduced bills. Savings depend on location and current usage.

Q:What happens if one of the tubes is broken?

Tubes are strong but can be replaced easily if broken. The system can operate with several broken tubes, though efficiency drops. Broken tubes should be replaced immediately.

Q:Will water be heated on a cloudy day?

Yes, the collector still provides heating on overcast days. On heavily clouded or rainy days, additional gas or electric boosting may be required to maintain temperature.

Q:Can I use a solar collector with my existing hot water system?

Normally yes. Simple retrofit valves can connect solar to your existing cold water inlet. If direct connection isn't possible, an additional storage tank can pre-heat the water.
