Solar Batteries
With the ever increasing price of gas, oil and electricity, using the stored energy to light and heat your house is fast becoming a worthwhile investment. When the daylight hours have disappeared and the solar panels no longer generate electricity. It is at this point that the batteries come in handy to power your home or office but certainly heat your water!
Many people are unaware of the benefits of Solar Battery Storage. This system stores excess solar energy that is not immediately consumed by a building. The solar panels don’t always produce enough energy for a house to power itself, but a storage battery can help you store the energy for later on when you’re back home. It will also keep your devices running at night or when the sun is not as prominent. These batteries are designed to provide you with uninterrupted power for several hours.
A standard solar power system connects to the grid. When energy is in short supply, it will be drawn from the grid and billed to the consumer. In the case of a battery, the energy is stored. A battery is a secured source of energy. It is very useful in regions with unstable grid electricity. The batteries can also be an asset for processes that use energy. This feature is ideal for home owners who live off the grid or need a steady supply of energy.
In addition to protecting your home and business from blackouts, solar battery storage can also help you lower utility bills. You can use the excess energy from the batteries to run specific appliances or load your home during evening hours when utility bills are higher. A large number of customer’s who have installed solar PV with or without a solar storage battery. They are making substantial savings on their energy bills.
Having a backup battery for your solar energy system can help you save money on utility bills. The storage also allows you to manage your time-of-use bill with ease. If you are planning to install a solar power system in your home, make sure to consult our professional experts to help you decide the best option.
Our Solar PV Packages include everything you need to generate and store your own Solar energy. By installing both Solar Panels and Solar Batteries, you are able to generate and store solar energy to be used at any time, making your home more energy independant and increasing your overall savings.
Benefits of Solar Batteries:
1. Less reliance on grid supply:
It is possible to use more battery and solar power than grid-connected power depending on the inverter settings. It is easy to see that your energy bill will drop significantly.
2. Power backup for the home:
When you live in an area that experiences power blackouts more often, consider opting for a solar battery storage system. It acts as a power backup for the home anytime the grid supply is unavailable.
3. Independence from the grid power:
It is common to find grid companies increasing their prices from time to time. If there is a sufficient solar battery storage system, then you can have a lot more independence from the utility company’s tariffs.
4. Ease of setting up:
It is worth mentioning that the setup process is easy. So long as you get high-quality solar batteries, the rest becomes easy. Our experts can help you in connecting batteries to the solar panels.
5. Years of dependable power:
High-quality batteries will give you years of reliable power. Over time, your battery capacity may drop slightly. Nevertheless, the return on your investment will be worth it, to say nothing of the positive impact that you are having on your environment.
Types of Batteries
Not all batteries in the market are ideal for solar applications. The next time you are looking for solar battery storage in Pakistan, consider only those designed for solar systems applications. We classify the batteries based on their chemical composition and the type of power they can supply to the electrical load.
1. Lithium-ion or Lead Acid Batteries
Lead-acid batteries are further categorised as flooded or sealed solar batteries. The flooded lead-acid battery has a better lifespan compared to the sealed lead-acid battery. It will last for 5 to 7 years versus 3 to 5 of what you get with a sealed lead-acid battery.
The flooded lead-acid battery will require more maintenance but can keep going for years, giving you dependable power. If you are looking for a cheaper solar battery, consider the lead-acid batteries.
Lithium-ion batteries, are the most popular choice for being compact and having more capacity. Good brands will last for a minimum of 10 years compared to 5 years for lead-acid batteries. Having a better performance means paying a little more for them, however, they will provide a better return on your investment over the long term.
Although lithium-ion batteries are the more expensive option, they still offer excellent value for the money. Once a lithium battery system is set up in a house, you can be sure of dependable performance.
2. AC or DC Batteries
For solar applications,Direct Current (DC) batteries are the best. They do not need an additional inverter to connect them to the solar panels. All you need is a charge controller for charging the batteries at the recommended current.
The charge controller is based on the current that the solar panel array generates. The charge controller capacity needs to be more than the solar panel array charging current.
The Alternating Current (AC) batteries can still be useful in a solar battery storage system, but you will need an additional inverter to retrofit them.
It is best to speak with our experts to understand which battery type would be ideal for your needs.
Properties of the Best Solar Battery Storage
When looking to buy a solar battery storage system in Pakistan, you will likely come across many options. Sometimes it can be confusing to decide which battery storage system is best suited for you. Below are some of the factors you should keep in mind.
1. Ongoing maintenance:
Depending on the battery type that you choose, some will have more ongoing maintenance needs than others. Take the time to understand the kind of maintenance the solar battery storage system will require. The maintenance costs are expected to be more when you are using a flooded lead-acid battery. It will require the addition of distilled water and other types of maintenance to keep it working efficiently. Do not worry as this does not happen frequently.
2. The brand:
When you are choosing solar battery storage, the brand is important. There are top brands in the market known for making high-quality batteries that last longer. Speak with one of our experts for more details on the quality and different brands for the solar batteries in the market.
3. Capacity:
The capacity is the biggest factor you will have to consider. Its unit of measure is kilowatt-hours (kWh). Remember that if you want to run more electronics and appliances for longer, you need a bigger capacity battery. The size of your solar array will of course play a part in deciding. Capacity can be misleading sometimes. You cannot use the entire battery capacity. When the battery gets to a certain capacity, then a recharge is necessary. Always look at the “usable capacity” of the battery before investing in one.
4. Depth of discharge:
Thedepth of discharge (DoD) will dictate how much battery capacity is available before you need to recharge the battery. The DoD will vary from one battery to another. If it is lithium-ion, then the DoD is 80% to 100% and 50% for most lead-acid batteries.
5. Warranty:
The warranty can offer peace of mind for your investment in solar battery storage. A solar battery warranty is generally based on the number of cycles the battery will go through in its lifetime. A cycle is one complete discharge then a complete recharge. Depending on the battery type, sometimes the discharge can only get to 50%, then a recharge is necessary. So, it would take two of these processes to form a complete cycle. Looking at the available batteries in the market, most have a 10-year warranty. This should be enough time to utilise the battery to suit your power needs.
