Reliable and Qualified Systems for Solar Power Plants

Our life energy; lights and heats our planet Earth and one of the most fundamental elements of natural life.. The Sun. The Sun is actually a giant fusion reactor that creates 15 Million °C heat and expands it all over the space with radiation as a result of the reaction when hydrogen atoms convert into helium. Solar radiation outside of Earth’s atmosphere is almost stable and around 1370 W/m2 however on Earth it varies between 0 and 1100 W /m2.

Solar energy utilization potential is quite high. The Sun delivers 8.000 times more of the energy we consume annually that is equal to 12,5 billions of oil (1). Plus, its both environmentally friendly and free! Thus, it is inevitable to use solar energy which can be identified as infinite instead of energy sources that harm the nature and in time will run out.

But how and how much can we produce energy when we use solar? When all possible electrical losses are considered and solar panel efficiency is determined as 10%, a solar plant in the Sahara desert on a 800×800 km² land is calculated to provide all energy need of the Earth. However, constructing a plant on a single location with such a scale would increase energy distribution problems and costs significantly while making it harder to respond when needed. So installing photovoltaic systems to areas with plenty of sunlight where requirements are calculated can address these issues. (1)

Attempts to generate electricity from solar energy began earlier in developed countries than Turkey. Turkey has been carrying out research, development, catch-up and demonstration efforts since 1982. The Atlas of Solar Energy Potential (GEPA) prepared by the Ministry of Energy stated that the country has annual 2.737 hours of sunshine (7.5 hours daily) and a total of 1.527 kWh/m².year annually (4,2 kWh/m² daily total).

The share of renewable energy resources within total energy generation of Turkey is targeted to reach at least 30% by 2023. Energy distribution and expanding renewable power generation plants is crucial for reaching this target. This would decrease the dependency on fossil fuels and external sources as well as minimizing distribution and transmission losses. In Turkey, at the end of 2015 362 unlicensed GES (Solar Plant) were operating with 248,8 kW installed power but as of 31 July 2016, 733 unlicensed GES (Solar Plant) is operating with 562,1 MW installed power. (4) Total share of electricity generation of GES has risen to 0.7% from 0.2%. But it is crucial to accelerate the process and address the technical barriers in front of GES with engineering solutions for the %30 2023 share target. (2)

How to generate qualified energy continuity?

End user energy quality transmitted from solar plants was gazetted by EMRA (Energy Market Regulatory Authority). As stated in the 2006 September dated regulation number 26287, Energy Distribution Companies are also liable to transmit continuous and qualified energy. For this reason, Solar Plant projects inevitably have to prefer reliable and qualified products for transmission and distribution of electricity. Since 1980, all institutions on transmission and distribution of electricity preferred Elimsan products.

Elimsan MV Distribution Switchgears, Monoblock Concrete Kiosks and HV Disconnectors have been used in Solar Plant Projects for years. Elimsan Metal Enclosed Switchgears were used at Turkeys first and single highest capacity solar plant Malatya İnönü University Turgut Özal Medical Center. After that came Burdur Solar Plant and Emel Solar Plant projects. After the incentive to use local produced products in renewable energy projects, Elimsan MV energy distribution products started to be preferred in the sector even more. To put this in figures, Meram, Aras, Dicle, Osmangazi, Ak EDSAŞ distribution companies used Elimsans 164 different types of Metal Enclosed Switchgears and Monoblock Concrete Kiosks for GES projects in Konya, Nevşehir, Erzurum, Şanlıurfa, Afyon / Dinar and Kahramanmaraş cities.

Elimsan is also a preferred brand in other renewable energy plants such as  wind, water and biomass.
