Solar Energy Battery Storage System: Is It Worth The Investment?

Are you thinking about getting solar panels but are worried about bad weather? At Enopte, we have the perfect solution! We offer solar energy battery systems that work as a backup power source no matter the weather or time of the day.

Our company also offers multiple options so that you can have a system that fits the needs of your home or business. With a solar energy battery storage system, you’ll be able to make the most out of self-generated solar electricity.

Benefits of A Solar Energy Battery Storage System

Don’t just stop at solar panels. Adding a battery gives you the ability to store self-generated electricity instead of feeding it back into the grid. Here are some of its key benefits:

  • Save on utility costs: Instead of sending excess energy directly back to the grid, you can store it for future use. This enables you to significantly reduce your energy consumption.
  • Green living: A solar battery system lessens your reliance on coal or gas-powered electricity. With this, you can reduce your carbon footprint and use more green energy.
  • Backup energy source: Use the energy stored in your solar batteries in case of a power outage or bad weather.
  • Go off-grid: Build an energy-independent home or business by investing in a solar energy system. You never have to worry about rising electricity costs ever again!

Benefits Of A Battery Backup System

Getting a solar battery can be a great investment for your home or business property. Here are some of the key benefits of getting a solar energy battery system:

Power Up Your Property At Night

Solar panels work by converting sunlight into electricity. If this electricity remains unused, it’s exported to the grid for a modest feed-in tariff rate.
With a solar battery, you can store excess energy produced during the day. Later in the evening, you can draw power from the battery instead of consuming electricity from the grid.

Save Money

Having a home battery backup system lessens your reliance on electricity from retailers. You never have to worry about the rising costs of electricity ever again.

At Enopte, we even have a proprietary Energy Management Dashboard that helps you keep track of your consumption and stay on budget. It produces minute-by-minute reports and helps you monitor your batteries’ performance.

Gain Backup Power

If you lose electricity, it’s easy to think that you can simply switch to solar power. But unfortunately, solar panels still need electricity from the grid to work, unless they’re connected to a battery.

The battery does the double duty of powering up the solar system so that it continues to produce energy. It also helps you power up your home.

Enopte also gives you the option to add a diesel-powered backup. Even after you use up all the stored energy from your batteries, you won’t have to live in the dark.

How Do Battery Energy Storage Systems Work?

Solar energy systems aren’t as complicated as they seem. Here’s a step-by-step guide on the process.

Solar panels, which are made up of photovoltaic (PV) cells, absorb photons from sunlight. This process produces direct current (DC) electricity.

If you still have excess energy after your solar batteries are fully charged, the system will begin sending energy back into the energy grid. The feed-in tariff refers to the amount of money that energy retailers pay you in exchange for providing them with electricity.

Before your home appliances can begin using DC electricity from your solar panels, it should first be converted into alternating current (AC) electricity. A solar inverter or hybrid inverter converts the energy and directs it to your house or building’s switchboard.

The switchboard acts as the control centre for the electricity in your home or business property. It helps make sure that you consume solar energy before accessing energy from the grid.

Here’s where the solar battery system comes in. Excess electricity is used to charge solar batteries which will be stored for future use. You can activate your solar batteries at night or in case of a power outage. You can also use it during stormy weather when energy production from your solar panels is low.

Electricity retailers usually install utility meters to households and business properties. This meter will be responsible for recording the amount of energy that’s consumed by your property. It also checks how much electricity you feed into the grid.

Is An Energy Storage System Battery Worth It?

Investing in a solar battery enables you to consume most of your self-generated electricity. But in order to determine if it’s really worth your money, you should look at the following factors:

  • Individual electricity requirements: Checking your household’s consumption is the easiest way to determine if getting a solar battery is worth it. If you’re having trouble keeping up with your utility bills because of high consumption, storing and using energy from your solar panels may be worth the initial investment.
  • Feed-in tariff rate: Most energy retailers compensate households and businesses for sending excess electricity back into the grid. The rate they give you depends on the current feed-in tariff rate. If the rate decreases to a point that sending energy back into the grid no longer makes economic sense, then you should begin considering getting a solar energy battery.
  • Future utility costs: If you expect the price of electricity to rise even more, then getting a solar battery will protect you from these future expenses.
  • On-grid/off-grid setup: If you plan to have a house or business property that has no connection to the grid, then getting a off grid solar battery system makes sense. The solar battery will serve as your backup source of power at night or days with bad weather. Our solar battery at Enopte even comes with a diesel-powered generator to minimize power outages.

Can I Add A Solar Battery To My Existing System?

Yes. But before you add a solar battery to your existing system, you have to first check the following:

  • Production capacity: Compare your solar energy production versus your consumption. If you are not producing enough electricity to cover your home or business’ consumption, then you won’t need a solar battery.
  • Solar panel setup: Talk to us about your current solar panel setup. We’ll help you assess if you need to add more solar panels to increase your energy production. That way, you can produce enough energy to store for future use.
  • Time of consumption: Check the time you use electricity. If you mostly use electricity at night, then it would make sense to get a solar battery. This will allow you to use the power that your solar panels generate during the day.

Choosing The Best Battery For Your Solar Energy System

There are a number of factors you should consider when picking the right solar battery. In this section, we’ll help you understand how to choose the right battery for your home or business.

Types Of Solar Batteries

Batteries are classified depending on their chemical composition. Typically, you can find the following:

  • Lithium ion: Most solar energy systems, including the Enopte Power Station, use lithium-ion batteries. These have a longer lifespan and have a higher depth of discharge.
  • Lead acid: Lead acid batteries are best for those who are looking for a low-cost system. However, keep in mind that their battery life is shorter than lithium ion batteries.
  • Saltwater: Saltwater batteries use saltwar electrolytes instead of heavy metals to maintain its charge. That makes them more environmentally friendly and simpler to recycle.

Solar batteries come with different storage capacities, which are measured in kilowatt-hours (kWh). You can opt to purchase one battery or “stack” multiple ones to get extra capacity.

You can select one based on how much electricity you consume and how large your property is. At Enopte, we give you the option to choose from the following:

  • Home – 7.5 kWh
  • Small Business – 15 kWh
  • Medium Business – 30 kWh
  • Large Business – 45 kWh

A battery’s capacity tells you how much energy it can store, but it won’t tell you how much energy it can deliver one time. For that, you’ll have to look at the battery’s power rating, which is measured in kilowatts (kW).

Having a battery with a high capacity and low power rating would be able to supply a low amount of electricity to your property for a long period of time. You can use this to power crucial appliances, like your computer or your lightbulb.

Meanwhile, a battery with a low capacity and a high power rating can run all the appliances in your property, but only for a short period.

Round-trip efficiency refers to the amount of energy that you can use compared to the amount of energy that the system spent to store it. A higher round-trip efficiency means you’ll be able to get more power out of your battery.

For example, if you store 10 kWh of electricity to a battery that has an 80% round-trip efficiency, you’ll only be able to use 8 kWh of useful electricity out of it. The remaining 2 kWh was spent storing the rest of the electricity.

Most types of batteries need to retain a certain amount of electricity at all times to avoid getting discharged. For example, if you have a laptop or a smartphone, you shouldn’t wait until it reaches 0% before you charge it. The same concept works for solar batteries.

When shopping for solar batteries, it’s best to look for one with a higher DoD. This allows you to use more of your battery’s capacity before you’re required to begin charging it. If you keep using up the full capacity of the battery past its depth of discharge, then you risk shortening its lifespan significantly.

All batteries go through a “cycle” of charging and draining. However, a battery’s ability to hold a charge decreases over time. With that said, solar batteries have a limited number of cycles. 

When shopping for a good solar battery, you should look for one that can last 5,000 cycles or more. This usually means that it can last for about 10 years.
