What is an Off-Grid Solar Power System ! How it works !

Off-grid Solar Power systems work independently. They are not connected with electricity power grid. In off-grid solar power systems, during the day, solar panels convert solar energy into electrical energy. The electrical energy so produced is then, through solar charge controller is stored in battery banks. During the night , when the sun is not there or weather is cloudy, power stored in batteries is used for running the electrical appliances, and lighting purpose. The system usually consists of solar panels, battery, charge controller, grid box, inverter, mounting fixtures & accessories.

Off-Grid Solar Power Systems are totally self-sustaining and can provide power for critical works in areas where a power grid is not available. These can be used in out of grid remote areas, where power requirement are not much demanding.




Generally Off-Grid Solar systems are designed with extra capacity so that in the daytime, sometimes, not only they can meet the critical power requirement, but can charge the batteries, thus storing the energy. The energy stored in those batteries can then be accessed when the system is not producing, like at night or during cloudy weather.




Most off-grid solar systems are designed to produce a certain amount of “extra” electricity in the daytime, which is sent to batteries for storage. The energy stored in those batteries can then be accessed when the system is not producing, like at night or during cloudy weather.


Off-Grid Solar Power System Applications:


Electricity supply in rural and remote areas : Off-grid Solar Power Systems can facilitate independent, long-term and sustainable electricity generation in rural and remote areas.

Power back up in areas with frequent electricity cuts - A number of places in India face frequent power cuts due to power transmission malfunctions, which can hamper operations of companies and public institutions. Off-grid solar systems can provide an economical and practicable long-term backup solution to overcome the problems occurring during frequent power cuts.

Depending upon demand for electrical power, solar systems can be sized to produce enough excess electricity, so that they can supply electricity around-the-clock.


However, despite even the best and most accurate estimates, the weather is unpredictable. If you experience abnormally cloudy weather several days in a row, your system may not be able to produce enough electricity to charge the batteries and fulfill all your needs.

While having extra batteries offers peace of mind and can provide a bank of stored electricity just in case this happens, they’re also expensive. Purchasing more batteries than you need may be cost-prohibitive, depending on your budget.


Key Features : Off-Grid Solar Power System:

  • Off-Grid Solar Power System can work independently and do not require power grid for power supply.

  • Off-Grid Solar Power System harness enough solar power during the day for battery storage, the same energy is used at night or when the power grid is down.

  • These are most suitable for remote areas where there power from electric grid is not there.
