Discover how solar panels, battery storage and intelligent energy management can help households reduce electricity costs.

When Electricity Prices Spike, a Home Battery Helps

On 14 September, electricity prices in southern Sweden exceeded SEK 11 per kWh, compared with around SEK 2.50 per kWh overnight.

“It was a record, but not an accident. These price swings are the market now,” says Peter Mårtensson Florea, Regional Manager Nordics at Solis.

That evening, a Solis-equipped home in Skåne used stored solar energy instead of buying electricity at peak prices, demonstrating how battery storage can help households manage volatile electricity costs.

How Does Solis AI Optimise Energy Use?

Integrated into SolisCloud, Solis AI analyses electricity prices, weather forecasts and household consumption patterns to optimise battery operation.

“Every 15 minutes, it asks one question: What makes the owner the most money right now? Use the power, store it or sell it,” Peter explains.

By coordinating solar generation, battery storage and household consumption, Solis AI helps homeowners make better use of solar energy and respond to changing electricity prices.

Can a Home Battery Generate Additional Revenue?

Where available, grid-support services offer another potential revenue stream. Through local partners and the Solis app, homeowners can participate in services that help support grid stability.

“There is money in it, but the payment varies, so count it as a bonus, not the base,” Peter says.

Actual returns depend on local market conditions and service availability.

Is Solar a Good Investment?

Peter recommends evaluating a solar-plus-storage system over a full year.

“A solar system is a financial product. Read it the way a loan officer would,” he says.

Before investing, homeowners should ask three questions:

●What is the total annual cost?

●What are the expected annual savings and potential revenues?

●Will the investment pay for itself before the warranty expires?

Electricity savings depend on consumption, tariffs, solar generation and system configuration. A full-year calculation is more meaningful than focusing on a single month. Peter advises homeowners to ask installers for the complete financial assessment, not just the final figure.

Smarter Energy Management with Solis

Solar panels generate electricity, batteries store it, and intelligent energy management helps determine when it delivers the greatest value.

As Peter puts it, “You are not spending money. You are moving it from the power company to your own roof.”

Solis develops solar inverters, battery storage solutions and intelligent energy management software for households and businesses.
