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.
