When you’re in the market for solar power, it’s common to have a lot of questions and considerations. One of the most common questions we receive is, can solar power be used at night? The answer is simple, and it lies in solar energy storage solutions, namely batteries. Let’s look at how batteries enable you to use your solar power, long after sunset.

Can solar power be used at night? Understanding solar energy storage

How solar panels work

To answer the original question, we need to start with solar panels and how they work. Solar panels generate electricity by converting sunlight unto usable electrical energy through the photovoltaic (PV) effect. This process is carried out during daylight hours when the panels are exposed to sunlight. The electricity produced can be used to power your home, business, or any other facility during the day.

The challenge: Nighttime energy

It’s all well and good to have solar energy throughout the day, but it’s the nighttime when we most commonly inhabit our homes and therefore use the most electricity. This presents a problem for meeting energy needs during the nighttime, when the PV effect is not in swing.

The solution: Solar energy storage

To address the issue of solar power availability during the nighttime, solar energy storage systems come into play. These systems, such as a hybrid solar system, include solar batteries to store excess electricity generated by solar panels during the day.

How solar batteries work

Solar batteries are small energy-storage devices that are used in a hybrid solar system. They can also be attached to your existing solar system – making it an effective hybrid system. Simply put, batteries capture and store your surplus solar energy, instead of exporting it back to the grid, so you can use it later. Batteries are a stable source of energy that work well as a backup power source during blackouts, as well as the nighttime.

Benefits of solar batteries

Solar batteries take your solar system to the next level by offering the following advantages for you: 

  • System efficiency: By storing excess energy in a battery, rather than sending it back to the grid, you can reduce your amount of wasted energy, and use it in your home
  • Energy independence: Acting as a source to draw energy during the nighttime, batteries help to reduce your reliance on the grid and therefore achieve greater energy independence for you 
  • Backup power: Stay connected to your own source of power during grid outages so you can avoid stress and disruptions to your household routines 
  • Sustainability impacts: By using more of the solar energy your system is generating for you, you can reduce your carbon footprint even more, and play a bigger part in a more sustainable future
  • Cost savings: By using your stored energy for longer and taking advantage of it during peak hours, you can save even more money on your energy bills!

So, while solar panels don’t directly generate electricity at night, solar energy can indeed be used after the sunset through the use of a solar battery. These systems enable the storage and utilisation of solar power, providing you with energy independence and cost savings. As technology continues to advance, solar batteries are becoming increasingly accessible with many locals opting to maximise the benefits of solar power.
