Solar energy has been available in Indian homes for a long time, but it was not economically viable for most Indians. However, over the years, both the central and state governments have introduced various policy-level initiatives that have significantly reduced the cost of solar panels in recent years. Indian solar panel manufacturers have also upgraded their production levels, establishing a strong presence in the market and creating a competitive and organized industry.
With rising electricity prices in India, everyone is looking to use devices powered by solar energy to effectively reduce their electricity bills over the long term. In addition to this, using solar energy helps reduce your carbon footprint. India has faced an electricity crisis for many years, and even today, the problem is not completely resolved. In small towns and villages, the situation is particularly serious, where people still face power shortages daily.
In Indian households, power cuts are common, ranging from 20 minutes to 8-9 hours. If there is no electricity for a longer period, appliances like refrigerators start to warm up, and other devices cannot be used. As a result, people in India are now turning to solar energy to overcome these power issues.
There are two main types of solar panel systems used in India: off-grid solar panel systems and grid-connected solar panel systems.
An **off-grid solar panel system** is ideal if your home experiences regular power cuts and you're looking for a power backup solution. This system includes a solar panel, MPPT charge controller, inverter, and a battery bank. The solar panel converts sunlight into electricity, while the charge controller ensures proper flow of current. The batteries act as storage units that store all the generated energy. The inverter functions like an engine, converting the voltage of the stored electricity to match the requirements of the devices. A solar hybrid inverter can also be used, which charges the battery when sunlight is available and draws power from the grid when it's not.
A **grid-connected solar panel system** is the best option if you want to reduce your electricity bill by using solar energy. This system does not include batteries. The electricity generated by the solar system is used directly in your home. If there is excess production, it is sold back to the electricity distribution company. If your consumption exceeds the solar output, the grid supplies the additional power needed. This system includes an inverter and a net meter. However, it is not suitable for areas with frequent power cuts because the inverter stops working when the grid fails, making it impossible to use the solar-generated electricity even if the system is operational.
Let’s understand how solar panels work with a UPS (Uninterruptible Power Supply). During power outages, devices powered by electricity can continue to operate with the help of a UPS. The inverter converts the DC battery voltage into AC, making it easier to power household appliances. With a UPS, you can run electrical devices for several hours during a power cut.
**Benefits of a UPS backup system:**
1. In areas where power cuts are frequent and prolonged, it is essential to have a reliable backup system. News often reports cases where thieves or robbers cut the electricity to commit crimes. In such places, having a solar-powered backup system ensures your home remains secure even during extended power outages.
2. You can also use such a security system in your office or shop, which runs on solar energy. You can connect security cameras to a solar-powered UPS system to ensure complete safety.
3. If you are working on a computer and suddenly the power goes out, a solar-powered UPS allows you to save your work easily, as the computer continues to run for a short period.
4. Solar-powered UPS systems automatically charge when electricity is restored, so you don’t need to check them frequently, giving you peace of mind.
In rural areas, solar-powered security devices have brought significant benefits to the general public, improving their quality of life. Devices like security cameras, lights, and alarms powered by solar energy have made life easier and safer for people living in remote areas, and this trend is expected to improve further in the future.
