How Long Does Solar Energy Systems Pay for Itself – With industrialization, the demand for energy in the world is constantly increasing. The use of fossil fuels such as oil, natural gas and coal is both costly and harmful to the environment. In addition, it is among the predictions that fossil fuels will be depleted in a short period of time as a result of the current usage intensity. The use of fossil fuels, which has many negative aspects such as global warming, climate change, and air pollution, leaves its place to renewable energy sources. Solar energy is also a highly efficient, environmentally friendly, and low-cost sustainable energy source.

Solar energy is basically the production of electrical energy thanks to the rays obtained from the sun. The electrical energy needed by both buildings and large-scale structures such as industrial establishments can be produced with solar energy. The capacity of solar energy can be easily changed according to the large or small sized panels installed according to the energy needs. Solar energy systems are low cost. Since it is a renewable energy source, unlike fossil fuels, this type of energy can be used without worrying about the depletion of the source.

Solar power system can be built in almost any location. The efficiency obtained from this system also increases when the panels are placed considering the angle that the location receives the sun’s rays throughout the year. Thanks to the electricity obtained from solar energy, the dependence of countries on foreign energy supply decreases and their current budget is balanced. Solar energy is also suitable for small-scale use, such as households. In addition, it is an investment branch in which large industrialized institutions can generate income by using the electricity produced and selling the surplus.

Low-cost maintenance costs, the use of completely natural resources, and the low fixed cost of cleaning are among the encouraging aspects of the solar energy system.
Payback Time of Solar Energy Systems

It is an indicator that expresses how long it will take to regain the investment amount spent for a depreciated venture. The return on investment in solar energy systems varies according to the type of system installed and the panels. Solar energy systems, which mostly generate electricity for the city grid and heat the water of the buildings, have a shorter depreciation period.

The important issue in electricity generation to be sold to the city grid is the pricing of the tariff applied by the purchasing state or the energy distribution company. The tariff in question is called “feed-in”. The cost of the electrical energy obtained from the photovoltaic type panel has been determined as 28 eurocents/kw in Turkey. The depreciation of the solar energy system is calculated over this fee schedule. With the said tariff, the solar energy system in Turkey can pay for itself in 4 or 16 years. The most important factor in the shortness of this time period is that our country benefits from the sun’s rays with high efficiency due to its location.

The position of the sun’s rays is a determining factor in the depreciation of solar energy systems. As an example, it is noteworthy that the amortization period in Germany is 20 years, despite higher tariffs and long-term purchase guarantees.

In cases where the price tariff called “Feed-in” is not applied, the depreciation calculation is calculated over the electrical energy consumed by the consumers from sunrise to sunset. In this case, the amortization period is longer than the standard “Feed-in” tariff.

Another factor that increases the amortization period is the variety of equipment used when installing the solar energy system. An extra energy storage device is needed in the solar energy system, which has an island-type system. This increases the investment cost. Off-Grid system independent of the grid should not be preferred in order to shorten the amortization period. Since the On Grid, the solar energy system connected to the grid, does not store electrical energy, it does not involve any extra cost.

The cost required for the installation of a grid-connected On-Grid system in Turkey is approximately 8 thousand Euros. According to the calculations, this system amortizes the investment cost in 7 years.
