Homes across Ireland
Solar panels and a battery, planned together.
Plan solar panels and a battery together around what your roof in Ireland can produce and when your home uses electricity.

Choose the panels and battery from the same information.
WRB looks at battery storage as part of your whole setup. We match the amount it can store and the power it can deliver to how you actually use electricity.
Your roof affects how much solar electricity you can produce. When your home uses electricity affects whether saving some in a battery will help.
WRB checks both options alongside your electrical system and any plans for EV charging or electric heating, so every part has a clear purpose.
What a good plan should help you do
- Balance likely solar output with your home’s electricity use
- Choose how much the battery should store and supply
- Make the solar equipment, battery controls and electrical system work together
What we need to know
You do not need every detail before getting in touch. Share what you know and we’ll tell you what matters next.
Storage and power are not the same
Battery capacity tells you how much energy it can store. Power output tells you how much it can supply at once. We check both against what your home or site actually needs, rather than choosing from a product headline.
Decide when the battery should run
A battery can store spare solar electricity or charge when electricity rates are lower. Agreeing what you want it to do helps us choose the right equipment and settings.
Choose a safe, practical location
Ventilation, access, manufacturer instructions, cable routes and your existing electrical system all affect where a battery can go. We check these before recommending a location.
Common questions
Is there an Irish grant for a home battery?
SEAI currently offers a €600 grant for eligible home batteries of at least 5kWh. Approval is needed before work begins. Check the current conditions in our grants guide.
Do I need a battery with solar panels?
Not always. A battery is useful only if it matches when you use electricity, how much solar electricity you produce and what you want it to do.
What do battery capacity and output mean?
Capacity is how much energy the battery can store. Output is how much power it can supply at once. Both need to match the equipment you want the battery to support.
Can a battery charge from the grid?
Many batteries can charge from the grid, depending on the equipment, your electricity rate and its settings. We agree how you want the battery to work before choosing the equipment.

Installing solar in Ireland
Plan the paperwork with the system.
For grant-supported work, check the contractor’s relevant SEAI registration and wait for the grant offer before installation. Agree the applicable ESB Networks connection route, electrical certification and commissioning records in your proposal.
A domestic SEAI solar installation also needs a post-works BER before grant payment. Your handover should explain the equipment, controls and support arrangements.
