Make the most of your solar energy production

Use more of your locally generated energy on-site. Designed for businesses and organizations, Cactos battery energy storage systems help you maximize the use of your solar energy and avoid selling surplus at low prices.

Unlock the full potential of your solar power

Use more of your production locally
Sunny moments don’t always align with your energy needs. By storing excess solar electricity for cloudy days, you can use more of your locally produced energy on-site.
Sell surplus when it’s profitable
When your solar panels produce most, so do others—driving prices down. Instead of selling surplus at low spot prices, Cactos lets you store it and sell later for a better price.
Lower your electricity bills
By saving your solar energy for later use, you reduce the amount you buy from the grid. Additionally, you can shift consumption to cheaper hours and minimize demand charges.

How does Cactos store solar energy?

When your solar power system produces more energy than you need, Cactos automatically stores the surplus—if it’s the most cost-effective option. Later, for example, after sunset, you can use the stored energy instead of buying it from the grid. All this happens automatically, so you don’t have to do a thing.

Maximizing the profitability of solar energy storage

Solar electricity storage based solely on optimizing production and consumption is not always enough to be economically viable. So how can you store solar energy in the most profitable way? By participating in ancillary service markets.

With Cactos, you can support the stability of the national electricity grid and earn compensation for doing so. Read more about profitable solar energy storage on our blog.

Oulun Baari maximizes its solar energy use

The family-run service station Oulun Baari installed a Cactos battery energy storage system to support its 1,000 m² solar panel system. This allows them to use their self-generated energy more efficiently while supporting the needs of their EV fast-charging station.
