Electricity Storage for Solar Systems

What is Electricity Storage?

Electricity storage, often realized through battery storage systems, acts as a repository for excess energy produced by photovoltaic (PV) systems. During periods of high solar production—typically midday when sunlight is abundant—but low consumption, the surplus energy is diverted to these batteries. This stored energy can then be utilized during the evening, night, or early morning hours when solar production is low or non-existent but the demand for electricity remains.

Advantages of Battery Storage

• Independent Power Supply: With a battery storage system, households can significantly reduce their reliance on the grid. This autonomy is particularly valuable during power outages or in remote locations where grid power is unreliable or unavailable.
• Reduced Dependence on Electricity Prices: By generating and consuming their own electricity, homeowners can shield themselves from fluctuations in utility prices. This becomes increasingly important as energy prices continue to rise globally.
• Emission-Free Electricity: Solar energy, combined with battery storage, provides a clean, renewable power source. This significantly reduces the household’s carbon footprint, contributing to the fight against climate change.
• Round-the-Clock Solar Energy Use: Perhaps the most direct benefit, battery storage ensures that the clean energy produced by your solar panels isn’t wasted. Instead of selling excess power back to the grid (often at a lower rate than what you would buy it for later), you can store and use it, achieving greater energy self-sufficiency.
