What is OFF GRID System?
Off Grid systems operate independently of the grid and with storage. They are stored and kept ready for use by means of battery panels, mostly in summer houses, vineyards and camps. In places where there is no grid line or no functional electricity grid, the healthiest solution is to install an Off Grid system that is correctly calculated according to the need. Since it operates independently of the grid, it should be designed to have enough battery capacity to produce sufficient power throughout the year and meet the needs of the facility even when there is no sunlight. Installations such as plateaus, mountain houses, farms, signaling systems, remote information systems (highway signs), base stations, etc. are frequently encountered.
These are solar energy projects implemented in places where grid electricity is not available or where electricity is frequently cut off. They can be called independent systems, island systems, Off Grid systems or battery systems.
The direct current electricity produced by solar panels is stored in batteries with the help of charge control devices. The stored energy is ready for use. During the hours when the sun is shining, the energy after the batteries are full directly feeds the electrical devices. In order to use the electrical devices, the direct current energy stored in the batteries must be converted to the alternating current used in the network. An inverter must be added to the system for this process.
Advantages of Off Grid Solar Energy Systems
In addition to providing financial advantages to its investors, it enables them to contribute to a sustainable energy future by offering significant benefits such as reducing environmental impact and energy independence.
- Savings on Energy Bills
Thanks to the solar energy system, some or all of the electricity needs of your home or workplace can be met through solar panels. In this case, significant savings can be achieved on energy bills. - Generating Income
Excess electricity produced can be sold to the grid and thus generate income. You can receive payment from the electricity company by selling the excess energy you produce to the grid. Since solar panels have a life expectancy of 25 years, they will provide a long-term investment by turning their cost into profit within a few years. - Flexibility
It has a flexible structure as the system can be installed according to the desired size and area. If the area is sufficient, the installed power of the system can be increased by adding new panels. - Environmental Awareness and Green Image
Solar energy is a clean and environmentally friendly energy source. By using this system, you can reduce your carbon footprint and contribute to environmental sustainability. In addition, you can create an environmentally sensitive image by using green energy. - Energy Independence and Security
Thanks to the solar energy system, you can meet some or all of your own electricity needs and achieve energy independence. At the same time, energy security is provided because you are connected to the grid. - Increasing Property Value
Installing a solar energy system will increase the value of your home or business. Solar Energy Systems are seen as a valuable investment in terms of energy efficiency and environmental sustainability. - Taking Advantage of Government Incentives and Discounts
In order to encourage the use of solar energy, the government offers incentives and discounts that change from time to time. By taking advantage of these incentives, you can install solar energy systems at more affordable costs. - Social Responsibility and Contribution
By using solar energy, you reduce dependence on fossil fuels and fulfill your social responsibility as an environmentally friendly energy user. - Expandable Energy Storage
Energy production capacity can be increased over time according to changing conditions. Battery selection is very important in Off Grid (storage) solar energy systems and should be analyzed well. When the right battery group is selected, it will be a long-lasting system. Since there is no need to obtain permission from the electricity distribution company for these systems, they can be put into operation in a very short time.
Importance of Off Grid Solar Energy System Design
In the first step, the existing equipment in the place where the system will be used must be replaced with energy-efficient products. In this way, the amount of energy consumed will decrease.
Then, the daily consumption should be measured. In order to make this measurement, it is necessary to list which home appliances are operated in the installation location and approximately how many hours per day. With this list, the daily/weekly energy needs of the house can be determined and the system calculation can be performed.
Whether the place where the system design will be made is a summer house or a place where people live all year round also has a serious impact on the system design and costs. If it is a place that will be used all year round, the panel design is made by taking into account the worst seasonal conditions.
If the place used is a seasonal or summer house, the first thing to know is the months in which the house is used. System calculations are made based on the radiation values in the summer months in the sizing. The inverter should be calculated with the voltage and power appropriate to the amount of instantaneous energy drawn according to the devices to be used. The most important issue in the inverter to be selected is whether the devices used (motorized devices such as refrigerators) are strong enough to handle the starting current. The inverter supply should be strong enough to handle this current according to the features of the device.
If the area where the system will be installed is a roof, the direction and slope of the roof should be calculated in detail. The equipment to be installed should be mounted in a way that will not damage the roof insulation.
If the system is to be installed in a garden, it can be installed with fixed legs or by installing systems that track the sun. Depending on whether the tracker is single- or double-sided, the amount of energy produced can be increased by 15%-35%.
During the transfer of energy as DC, the amount of energy lost can reach significant amounts as the distance increases. For this reason, the distance between the devices to be used (solar panel-battery-inverter) should be kept at a minimum level.
