Solar Panels Lightning Protection

HI, I am installing solar panels on roof. would like advise as regards lightning protection.?

Can I use normal earthing cablewhat size?

I don't know that solar panels require lightning protection anymore than the rest of the roof surface area.
There isn't anything about a solar panel that would attract lightning nearly as much as a standard TV tower.

I have a small solar system at my weekend peoperty & have had the solar panels installed for about 10 years without any lightning protection or ground connection directly to the panels themselves.

I have a ground connection just to the batteries with a 4 AWG stranded wire to a grounding stake driven about 4 ft into the ground.

I wouldn't try grounding the panels unless the manufacturer recommends it. I would think that grounding the panels will be more likely to attract lightning to the panels rather than protect them from it.

Applications of solar energy Israel

Since the foundation of the country Israel, solar energy has been exploited by the professionals to serve the mankind. Levi Yissar is the first person who developed the solar heater in the year 1950. This solar heater was used to alleviate the energy shortage in the country. These heaters were extensively used in almost all houses by the year 1967. Around 50,000 heaters were sold at that time. By this figure the importance of solar heater can be known. Another breakthrough in Israel was done by Harry Zvi Tabor who is known as the father of Israel's solar industry. He designed a prototype of the existing solar heater that used solar energy for heating the water and now it is used in almost all the Israel's house. The professionals and engineers are exploiting the solar energy Israel to the maximum extent and all the solar companies are working on several projects all across the world.

Israel has clinched the solar energy. There is oil scarcity in this country and hence the search of a stable source of energy is the major area of concern for all the scientists. The research and innovation center of Israel has advanced the solar technology to such an extent that it has become equivalent to the fossil fuels. This country is a hot country and thus the climate is appropriate for the solar technology to flourish. The Negev deserts receive high incident solar irradiance that has encouraged all the solar research and development industries to focus more on solar energy Israel. A feed-in tariff scheme was approved in the year 2008 that encouraged the architects to build numerous commercial and residential solar energy power station projects.

During the decades of 1970, there was no manufacturing industry for photovoltaic cells in Israel. The major challenge faced by this country was the rural lightning. Absence of photovoltaic manufacturing industries along with the high rates of photovoltaic cells forced the scientists to concentrate more on the issue of rural lightning. In rural bus stops there was no lightning and the dwellers were facing large number of problems. But now solar energy Israel has enabled the photovoltaic rural lightning. The lighting units comprise a PV panel, a storage battery, a low-power lamp and control electronics for protecting the battery. Hence, the solar power is used for lighting the bus stops during the night hours.
