Lithium-ion battery cost has fallen since 2010 and it highly benefits the electric vehicle and renewable energy storage markets. Although Lithium-ion battery costs have fallen considerably, they are still not affordable for many home and business owners. Even if lithium-ion solar battery cost doesn’t fit in your current budget, planning for a solar system with energy storage will be a good idea for the future and save your money in the long run.
Why Install Batteries?
Grid-tied systems are required to shut down during blackouts, even when the sun is shining. This is a regulated safety design feature of grid-tied solar energy systems intended to prevent workers from getting electrocuted while performing repair work on power lines. Unless solar PV system has battery storage, solar system owners cannot use the solar power from the grid-tied solar PV system during power outages.
Installing batteries also enables the use of solar energy when the sun isn’t shining-night and cloudy days. Some utilities also charge higher rates during peak hours and for peak power consumption. Installing batteries allow customers to use stored solar energy instead of more costly grid power during peak hours and reduce peak power consumption. This option is becoming very popular in Hawaii and California, where cost of electricity associated with peak hours is very high.
If you are in the process of installing a solar panel system and want the option of battery storage in the future, it will be helpful to plan accordingly. If the solar system is designed considering storage option in mind, it will be relatively easy to add the batteries to the system in the future.
It is more difficult and more costly to add battery storage in the future if the solar system is not battery ready. Choosing a solar system with an inverter that has battery storage capabilities is one way to prepare for adding batteries in the future. This would enable the solar system to operate only as a grid-tied solar panel system until batteries are added. Therefore, it will be beneficial to consult a reputable solar PV system designer to avoid unnecessary expenses in the future. New Dawn Energy Solutions will work with you to design your storage ready solar PV system.
