With the spread of household photovoltaic power generation and the Solar energy in Pakistan, many people may have more opportunities to learn about and experience electrical equipment and systems.
In particular, storage batteries have advanced rapidly in recent years and can now be used as a set with home solar power generation systems. However, it is challenging to understand storage batteries’ specific advantages and disadvantages compared to solar power generation systems.
This time, for those considering cooperation between solar power generation and storage batteries, we will introduce the outline and types of storage batteries, the advantages, and disadvantages of household storage batteries, etc.
In the second half, we will explain the characteristics of industrial storage batteries, the advantages and disadvantages of using them, and self-consumption solar power generation.
That’s the point of this article.
Advantages of combining solar power generation and storage batteries
- Â Â It can be used as an emergency power source in the event of a disaster
- Save electricity by using the electricity stored in the storage battery at night
- The expectation of power saving effect by peak cut
- It can be used for self-consumption after the end of the FIT system
Â
Disadvantages of combining solar power generation and storage batteries
- Â Â The cost burden of household storage batteries is relatively large
- There are areas where each municipality needs help to receive subsidies.
- Installation space must be secured
- The life of home storage batteries is short, about 7 to 15 years
Advantages of combining home solar power generation.
 I will explain the merits of combining a home storage battery with a home solar power generation system.
Of course, it is possible to operate a residential solar power generation system alone, but considering the future FIT system and efficient operation, why not consider introducing a household storage battery?
Advantage 1. As an emergency supply in the event of disaster it can be used
Even a single solar power generation system can be used as an emergency power supply in a disaster. Still, it cannot generate power when it is cloudy or rainy. Therefore, there is a risk that it will be significantly affected by the weather at the time of the disaster.
Therefore, if you install a home storage battery, you can use the electricity stored the previous day, even if there is no power generation on a rainy or cloudy day.
Recently, the storage capacity has increased, so there are types that can be used for microwave ovens and IH cooking heaters. The practicality is also growing.
Advantage 2. Save electricity by using the electricity stored in the storage battery at night
The advantage of installing a home storage battery is that it can also be expected to save electricity.
For example, during the day, the electricity generated by the solar power generation system is used to cover the power consumption and store it. And since the solar power generation system cannot generate electricity at night, the amount of electricity purchased can be reduced by using the electricity stored in the storage battery.
Using solar power generation systems and household storage batteries in this way makes it possible to use electricity while reducing the amount of electricity purchased.
Advantage 3. Expected power saving effect by peak cut
Peak shaving saves electricity by reducing the portion of the day that consumes the most electricity. Using a household storage battery can save electricity by using the electricity stored in the storage battery during the time when electricity consumption is the highest.
The existence of household storage batteries that can achieve peak cuts without forcibly reducing the amount of electricity used is a great advantage for any household.
Advantage 4. It can be used for self-consumption after the end of the FIT system
A home storage battery is essential in operating a self-consumption solar power generation system.
If the FIT system were to end, the unit price of electricity sales would drop, the sale of electricity itself would be prohibited, and the merits of operating a single solar power generation system would decrease.
By combining it with a home storage battery, when switching to a self-consumption solar power generation system, you can take advantage of power-saving benefits such as consuming the electricity stored during the day at night or on rainy days.
If you are reading this article and have installed a Best Solar Panel company in Pakistan, but the FIT has already ended, or the FIT period will end soon, please get in touch with your local dealer as soon as possible before you lose money.
