How Much Solar Energy Can be Stored in Solar Panels?


It is an understatement to say that solar energy is being recognized by the world. It has been prevalent among homeowners for quite some time now. In fact, the government incentivizing its use has also helped in boosting its popularity. Despite this, a majority of onlookers are still skeptical.

There are folks who want to use solar panels but doubtful of its risks and complexities. One of their most common questions is about storing solar energy.

How much solar energy can be stored in solar panels? The answer is none—solar panels can’t store energy. For you to store solar energy, you need to invest in energy storage devices.

Energy storage

Back in the days, electricity generation primarily consisted of burning fossil fuels. And because this proved to be dangerous for the environment, governments and advocates turned to renewable energy sources like solar power and wind power. Since then, off-grid electrical use has spread to mainstream markets.

Indeed, solar power and wind power bring many benefits. However, that doesn’t mean they don’t have any limits. Wind power, in general, is uncontrolled; meanwhile, solar power is affected by cloud cover and unreliable at nighttime, obviously. This is where energy storage devices come in.

Types of energy storage devices

Energy storage devices, also called batteries or accumulators, store electricity and release it when needed. As most countries use renewable energy sources, energy storage devices also become in-demand among homeowners and businesspersons.

With the help of your solar panels, you can store solar power in various energy storage devices. Here are some examples.

Solar power batteries

Solar batteries convert the DC power produced by your solar panels into AC power you can use later. If you own a large property that requires more power, then you should opt for a battery with a higher capacity. As for longevity, lithium-ion batteries have longer shelf lives compared to lead-acid batteries.

Hot water tanks

If your family, community, or tenants use resistant-based heating, then you can benefit from installing solar panels and hot water tanks. The latter is a viable medium for storing surplus solar energy. It’s akin to using batteries, however, the stored energy is in the form of heated water, which is stored in an insulated tank.

Ice tanks

Ice tanks convert solar energy into power for cooling and refrigeration. In some areas, refrigeration suppliers sell freezers with an add-on ice tank. If you have solar panels and you operate a facility that relies on cooling devices, you can definitely opt for units with add-on ice tanks.

Upon having this option, you can be more self-reliant and save more on power costs. The ice you have can also be melted for space cooling purposes.

Final notes

Now that you have these ideas about energy storage devices, it’s time for you to start exploring local solar panel suppliers. When finding local providers, you should hire one who offers solar panels and storage devices. Once you find a reliable supplier, make sure they can cater to your house’s or property’s requirements.
