An easier way to start the battery decision

Build a clearer battery brief for your home

Answer a few practical questions about your home and plans. Get a clearer brief, then connect with suitable specialists when you’re ready to compare your next steps.

Start the battery calculator

Battery size is only part of the decision. Keep evening use, future loads and backup expectations in view. Use your result to ask better questions of the right specialist.

A home battery decision starts with a simple question: what do you want your home energy system to do? Perhaps you want to make better use of your solar, shift more of your household’s electricity use into the evening, prepare for a home that will soon charge an EV, or understand whether storage deserves a place in the plan. The battery calculator helps you explore that decision using your household information. It is a starting point for a better conversation—not a promise of savings, a final design or a substitute for property-specific advice.

Begin with the household, not the hardware

Battery capacity can sound like a technical shopping exercise. In real life, the useful question is what happens at home after the sun goes down. Dinner is cooked, the television is on, devices are charging and the air conditioner may still be working. A battery is relevant only in relation to those patterns.

Think about the hours when your home is active, the appliances that matter most and the changes you expect over the next few years. A household that is quiet during the day may be making a very different decision from one with someone working from home, a pool pump running or an electric car returning each afternoon.

Which parts of your electricity use happen in the evening?
Are your household routines likely to change soon?
Do you want to explore storage for everyday energy management, backup considerations or both?

What the battery calculator is helping you investigate

The calculator is designed to turn a broad question—‘Would a battery suit us?’—into a more considered starting point. It can help you organise the information that matters before speaking with an energy professional and highlight the questions that need a closer look.

Treat the result as an indication rather than a verdict. A calculator can work from the information entered. It cannot see every detail of your roof, electrical setup, existing solar system, network requirements, installation conditions or future household plans.

The household habits behind that direction
Questions to take to a suitably qualified supplier
The details that still require property-specific confirmation

The inputs that make the result more useful

The quality of the conversation depends on the quality of the picture. Use the information the calculator requests as carefully as you can, and avoid filling gaps with optimistic guesses. If you are unsure about a figure, make a note of it rather than quietly treating an estimate as fact.

Your electricity bills, solar information and a clear sense of when the home is occupied can all help frame the decision. So can a little forward thinking: an EV, heat-pump hot water, home office, induction cooking or a growing family may change the shape of your future electricity use.

Recent electricity information, where available
Your existing solar or energy setup
Typical daytime and evening routines
Large appliances or equipment that affect household use
Likely changes to the home over the next few years

Read the result as a conversation starter

A calculator result should make the next question clearer, not close the case. Look at what the result appears to assume, which information you supplied and which details remain unknown. If the outcome feels surprising, that is useful: it may reveal a gap in your data or a difference between what you imagined the battery would do and what you actually need.

Pay particular attention to the distinction between using stored energy during ordinary household routines and expecting a battery to provide backup during an outage. Those are related considerations, but they are not automatically the same thing. Ask the supplier to explain what any proposed system is designed to do and what equipment or configuration that would require.

What household behaviour is the result based on?
What assumptions should be checked?
Does the result reflect what you want the battery to do?
Which parts need confirmation at your property?

A battery is one part of an evolving energy plan

Your home may not stay electrically familiar for long. A second EV, a new air conditioner, electric cooking, a workshop or a change in working arrangements can alter when and how much electricity you use. That does not mean you should buy for every possible future immediately. It does mean the decision deserves a little room for what is genuinely likely.

The most useful plan connects the battery question with the life it is meant to support. It considers today’s pattern, plausible next steps and the professionals needed to assess the property properly. The calculator helps with the first part of that thinking. I LOVE SOLAR can help you take the next step by matching your situation with appropriate energy suppliers to investigate the details.

Separate what you need now from what you may add later
Ask how future equipment could affect the plan
Confirm technical, installation and backup details with the relevant professional
Compare recommendations by fit and explanation, not just by headline price

Before you act on a calculator result

A number can be helpful and still be incomplete. Before making a purchase decision, have the proposed system reviewed against your home, existing equipment, electricity use and intended outcome. Ask for clear explanations of what is included, what is not, and which claims depend on assumptions that may change.

You should also be clear about the role of the professional you speak with. I LOVE SOLAR does not install batteries. We help households frame the decision and connect with suitable suppliers for the next conversation. The aim is less guesswork, fewer awkward surprises and a plan that belongs to your household rather than a standard package.

Keep the calculator result and your source information together
Request a property-specific assessment before committing
Ask how the recommendation changes if your household changes
Confirm any current pricing, incentives, technical requirements or network matters directly
