Best performance is achieved with direct sunlight. However, energy saving is guaranteed even on cloudy days thanks to diffuse radiation.

No, the system only works in daylight. At certain times of the year, there is an insufficient amount of daylight. This is why every system has a back-up heating source.

Your Solar Hot Water System produces no emissions whatsoever. It operates without any discharge of greenhouse gases or other pollutants. In fact, each kWh produced by solar energy saves 0.24 kg of CO2 emissions.

Each kWh produced by solar energy saves 0.24 kg of CO2 emissions. A 2 m2 collector produces approximately 6kwh each day in Israel. A 2 m2 system with 340 days of consumption will save 500kg of carbon dioxide a year. Over 15 years of service, it will save 7.5 tons.

Yes, but the energy used in manufacturing the system will be recovered after only two years of use.

Yes, the system will work in cold temperatures. However, it does not work if the panel is covered with snow, as this prevents light from striking the absorber plate.

Nothing. If snow collects on the glass surface of the collector, it will melt rapidly. In fact, the design means that it will melt more rapidly from the collector surface than it will melt in other areas of your roof.

There is no need to. These will not significantly impair performance and when it next rains, any dirt will be washed off.

No, it is better to keep it on. Alternatively, you could consider covering the collectors instead.
Photovoltaic systems rely on silicone cells and solar energy to generate direct electric voltage. This is later inverted to usable alternating current at net voltage. The total PV system efficiency is 10% – 13% for the module itself. Solar systems which use solar heat rely on the sun’s radiation to heat the water in solar collectors. The heated water is collected in a storage tank, while the average solar water heating system efficiency is 40-50%.
