The very first action in discovering a suited photo voltaic vitality storage program is identifying your wants. It is essential to think about every little thing, such as the number of appliances you are going to want to run.

Battery-primarily based photo voltaic storage techniques want about 5 hours of daylight for every day for best performance. If you have adequate sunlight publicity, this should not be an issue. But if you live in a spot with regular cloud include, it might be worth taking into consideration an different alternative.

2. Choose a Battery

There are a few distinct sorts of batteries you can decide on from when you’re setting up your photo voltaic electricity storage method. These incorporate:

  • Lead-acid
  • Lithium-ion
  • Saltwater

Lead-acid batteries are the cheapest selection, but they also have the shortest lifespan. They also need far more servicing. The worst component is that they drop their demand if not used.

Lithium-ion batteries are the total opposite. They work well above prolonged intervals. Also, they don’t normally want much routine maintenance, but they cost far more than direct-acid batteries.

Saltwater batteries are new on the industry but are a lot more cost-powerful than lithium-ion batteries.

3. Connect Your Battery to Your Inverter

All photo voltaic panels appear equipped with an inverter. It requires the immediate recent generated by your panels and modifications it into alternating current. This way, you can use it in your house.

Connect your inverter to the grid. This way, you can switch amongst the energy produced by your panels and energy from the grid as needed.

4. Charge Your Storage Device

The fourth stage in harvesting photo voltaic energy is charging your storage device. You require a way to keep the strength you make due to the fact you cannot use all of it as it’s generated.

Charging the battery is best carried out with an onboard charging circuit created for the specific variety of battery. There are a lot of varieties of batteries. Each demands different demand voltages, recent, and manage circuits.

Also, set a cost controller amongst your solar panels and battery. It will avoid overcharging your system.

5. Turn Off Non-Essential Appliances

An superb way to guarantee you make the most out of your solar strength is to turn off all non-important appliances. It will help you save and retailer solar power to use when essential. You are going to also decrease your reliance on the national grid.

Alternative Methods of Storing Solar Energy

Besides storing solar energy in a battery, there are several other ways of solar energy storage. These include:
  • Thermal Solar Storage: Solar thermal technologies convert sunlight into heat. It’s the same concept used to heat water. Thermal storage systems use a solar collector to heat a liquid or air to high temperatures and store that heat for later use. There are two options for thermal storage (medium-temperature systems and high-temperature systems). The material is heated to around 100°C in a medium-temperature system. You can use this system to heat water. High-temperature systems use materials that can be heated to over 800°C. These systems are expensive and are not in widespread use.
  • Mechanical Storage System: Mechanical storage systems can use flywheels to store excess energy that you can use later when needed. These systems use fewer materials than batteries. Also, they are more efficient because they lose little to no energy in the storage process. On the downside, mechanical storage systems aren’t as reliable as batteries. It’s due to their sensitivity to temperature changes. Also, they lose energy through friction.

Mechanical storage comes in three systems including:

  • Pumped Hydro: A mechanical storage system uses solar energy to move a large object that stores potential energy when raised. When you want to use the stored energy, lower the object, and it’ll power a generator as it falls. The most common example of this is a pumped hydro system. In this system, water is pumped up into a tank at a higher elevation when there’s excess solar energy available. Then, when you need electricity, the water flows down from the elevated tank through a turbine that generates power.
  • Compressed Air: This method compresses air using excess energy produced by a solar panel. Then, it stores it in an underground cavern or tank. When there is an increase in demand, the compressed air drives a turbine. Then, it produces electricity. A compressed air storage system has many benefits. One of them is being able to store a lot of energy in small spaces. Also, it provides electricity when needed without emissions compared with other methods.
  • Flywheel: The flywheel system is an inverter. It converts electrical energy into mechanical energy to store it. In this system, you can control the input power by controlling the voltage and frequency of the electrical source that charges the wheel. When there is excess power from solar panels, you can use this energy to charge the flywheel. Flywheels have been used as energy storage devices since early times.

Stage to Be aware: You can use pumped hydro and compressed air for commercial solar vitality storage.

Advantages of Storing Solar Energy

Even though solar vitality is cleaner and greener, it is even now not conveniently accessible. Storing solar strength takes time. As soon as you change it into electricity, it will be of wonderful support as it will save funds, time, and hard work.

Storing solar energy is helpful in many ways. Below are some of its benefits:
  • Balancing Electric Loads: Many people who buy solar panels are often interested in reducing their utility bills. On the other hand, many of these same individuals are also hesitant about investing in solar power. It’s because the energy generated by these systems is not always available for use. For example, during the night and on cloudy days when the sun is not shining, the energy generated by the solar panel will not be usable. You may need to draw electricity from the utility grid in some cases. This way, they’ll pay higher utility bills than they would like. One of the best ways to overcome this issue is using energy storage solutions. They allow you to store energy for later use. Also, you can use it when your solar panel isn’t generating as much power as needed.
  • Energy Resilience: Solar energy can provide a reliable, safe, and affordable energy source for homes and businesses. While solar energy helps save money on energy costs, it also improves the power grid’s resilience. Solar energy provides a cleaner source of electricity. It can help consumers be less reliant on the electric grid during peak demand times or when outages occur. Even with a small solar system, homeowners can remain self-sufficient. If there’s an outage, you’ll still have access to electricity while your neighbors are without power.
  • Reducing Costs: Storing excess solar energy can reduce strain on the electric grid by providing a buffer between supply and demand. It reduces the need for extra power plants to be constructed or activated to meet demand during peak times. It can also reduce costs. Also, it allows utilities to use cheaper electricity at off-peak times.
  • It Reduces Carbon Footprint: Solar energy doesn’t produce emissions. So, storing the solar energy generated reduces our carbon footprint. It prevents it from being released into the atmosphere. It helps us all breathe easier. Also, storing solar energy reduces pollution from burning fossil fuels such as coal and natural gas.
  • Stops Annoying Noise: Solar power provides clean energy. It can eliminate noisy generators that produce power through combustion. For example, diesel generators are often used as backup power sources. They provide electricity when the primary source fails, but they are noisy. Solar panels are quiet when producing energy compared to these generators.


But there are moments of the day when our need for this power exceeds the sum presented by way of traditional implies. That is the place solar electrical power arrives in.

When it arrives to photo voltaic vitality, there is no denying the exciting prospects of what the long term holds. Now you can harness this free of charge source of electrical power.

Solar strength storage techniques are widely needed to equilibrium offer and demand. Solar batteries paired with other solar vitality storage methods allow you to carry on your strength use even when the sun goes down.

In addition to, these vitality storage systems can minimize the expanding variety of power surges and outages.
