Should I invest in more batteries or solar panels?

There are several factors to consider when deciding between investing in more batteries or solar panels for your solar power system. One of the most crucial factors is the available space.

How to choose a solar panel battery?

The battery's capacity ought to be adequate to store any extra energy the solar panels produce, ensuring a constant power supply at night or during periods of low sunlight. Similarly, the efficiency of solar panels should be maximized to generate the maximum amount of energy during daylight hours.

What are batteries and solar panels in a solar energy system?

Before we dive into the specifics, let’s first understand the roles of batteries and solar panels in a solar energy system. Solar panels, also known as photovoltaic (PV) panels, capture sunlight and convert it into electricity. They are the primary components responsible for generating solar power.

Do solar panels need more batteries?

If you’re already generating large amounts of energy from your solar array with the majority being sent to the grid, more batteries will help your own energy efficiency and reduce your personal energy waste. Solar panels have a longer lifespan (25-30 years) compared to batteries (10-15 years).

What is the difference between a battery and a solar panel?

Solar panels generate clean, renewable energy, whilst batteries only store energy generated by solar panels or from the grid. If you have a large battery but are not filling it up regularly with solar energy, adding more PV panels is more advisable to maximise the battery’s potential.

Should I add a battery to my solar panel system?

By storing solar electricity onsite in a battery, you can avoid pulling expensive electricity from the grid when your solar panel system isn't generating enough power to meet your needs (like at night). Resiliency is another good reason to add a battery to your solar panel system.
