The smart collaboration between a battery system and solar panels

Learn more about how iwell’s battery system works together with solar panels and the benefits it brings to your business.

Reliable and continuous power supply

Our smart battery system, also called Cube, stores the power generated by the solar panels, for example, when the sun is shining and the solar panels are running at full capacity, but the solar power cannot be used immediately. During the night or on very cloudy days, when the solar panels generate less or no electricity, you can use the stored energy from the batteries to still run your business on renewable power. By doing so, you reduce the mismatch between solar power generation and consumption.

Less dependency of the energy grid

Some grid operators might start to limit the amount of solar energy that a company can feed-in. We see this happening already in the Netherlands, where the energy grid is way over capacity due to the rapid decentralisation of production and increase in demand of energy. Chances are that other countries might follow in the footsteps of the Netherlands when it comes to this overcapacitated grid. This will affect the contracted power you on which have agreed upon with your grid operator and will make you dependent of the capacity of the grid for feeding-in your solar energy. A smart battery system will give you the flexibility to store solar energy when it’s abundant and use it when you need it, without needing the energy grid to back you up.

No need to invest in bigger grid connection

Apart from your contract power, the physical grid connection is a factor in how much power you can draw from or feed-in to the grid. It’s the actual cable that connects your company to the energy grid. This connection varies in capacity and usually was commissioned at a given moment in time for a certain address or location based on the power needs. When for example (additional) solar panels generate more power than you are currently using, the excess electricity is fed into the grid. Especially with large solar installations, it may be necessary to have a heavier connection to handle this extra power. But a heavier connection also means higher grid management costs, besides the costs of the installation of the bigger grid connection.

Besides expanding your grid connection, you can also start using energy more locally. By adding a smart battery system to the mix, you can store solar energy and use it when needed. This doesn’t require a bigger grid connection as the energy is managed internally without using the grid connection for either feeding-in or consume energy from the grid. It will also save you so-called transportation costs of energy. Since you are using your grid connection less, the grid operator has to transport less energy through your grid connection.

Automatic optimal usage

A smart battery system can proactively control solar panels. This functionality is important when feed-in prices for solar energy become less interesting, as we are seeing happening in some markets. This happens when energy prices are low and it’s increasingly interesting to consume energy from the grid rather than feeding-in to the grid. Additionally, if there is the phenomenon of frequent and/or high imbalance on the grid, it can be very interesting to sometimes stop solar energy production in order to help balance the grid. A smart battery system can take care of all these things while guaranteeing you from your daily needed energy. It takes your usage into account and knows what buffers remain to use for things like imbalance trade.

Charge smarter

Want to expand your sustainable minigrid with EV chargers? Our smart battery systems enable this energy expansion without the need of extra investments in your grid connection. The smart battery system functions as the mediator between solar panels and chargers. It can maximize the usage of clean energy which was generated by your own solar panels. This will reduce CO2 emissions caused by your energy usage and will also reduce energy costs, since your are using your self-generated energy. A more advanced feature can even enable the battery system to be linked to a route planning tool through our API, which enables you to optimize your company process while becoming more self-maintaining.

Additionally, in many countries charging EVs through solar energy can generate emission certificates. These certificates are country specific and have various specifications and even names. But the essence is the same; charging EVs with (solar) energy can generated tradable certificates which represent a monetary value.
