Our Batteries

There are many factors to take into consideration when shopping for solar batteries for your home solar power system. Two things to keep in mind are the type of battery you’re looking for and what exactly you want to get out of your battery.

There are four types of solar batteries:

  • Lead acid batteries
  • Lithium ion batteries
  • Nickel based batteries
  • Flow batteries

Do I need Battery?

As we know Ireland is not known for its hot sunny weather, however, it is visible light that drives solar PV cells, not the heat from the sun. You would typically think that when the sun is not out, there wouldn’t be much solar energy.

 Thankfully this is not the case. Even cloudy Irish days have very good visible light levels and this resource is substantial. 

The other big advantage that Ireland has is that when seasonal intensity of visible light is at its peak, we have long hours of daylight.

Batteries Explained

The Step-By-Step Breakdown

Phase 1: Solar Power Generation

When solar panels have been installed on the roof or ground, their solar cells trap visible light from the sun and convert it to electricity. This electricity, in its raw form, is DC electricity or direct current. This electricity is converted by the inverter to AC electricity, which is then supplied to the home, and excess energy is stored in the battery.

Phase 2: The Battery Charges

On several occasions, solar panels produce more electricity than the home currently consumes. This excess electricity is then channelled to the solar battery or batteries (if multiple solar batteries were installed to store ample amounts of electrical energy). The amount of excess energy going to the battery determines the charging speed. Another factor that will determine the charging speed is the size or capacity of the solar power system.

Phase 3: The Battery Discharges

The solar battery discharges renewable energy on two occasions. There is a power outage, and the battery has to provide backup power, or the panel is no longer getting energy from the sun, or the battery has to take over the electricity supply from its storage capacity. The second scenario is the battery is used to store energy which is later used to the owner’s benefit for time-of-use rate plans.

Solar Battery Costs

A solar panel battery costs between €1,500 to €4,000. Fortunately, you can benefit from SEAI grants that can help fund your solar panel. Prices vary from property to property taking individual constraints into consideration. Please contact us today to get a quote

Battery FAQ's

Yes. But it would be expensive and depend on your usage, PV generation, and battery.

It would depend on multiple factors like your consumption, consumption patterns, battery manufacturer, battery type, battery size, solar energy system size, and amount of sunlight.

30% of daily usage is average 4 to 9 consumption

Typically 5KW to 8KW demand loads.

Yes, it can if your battery has an “islanding” capability.

No. The solar panels capture sunlight and charge batteries with PV.

Yes, technology has made leaps and bounds. But should be appropriately installed, permitted, and meet the NFPA (National Fire Protection Association) code. The biggest concern is thermal runaway.
