Energy management in the home
Combining renewable energy and battery storage to offer you greener, smarter, and cheaper electricity for your home.
HOW CAN WE HELP?
Energy prices are rising and we face an ongoing battle in the race against climate change as we strive towards becoming carbon neutral or NET ZERO. Most people know they know they need to do something, but don’t know where to start.
That’s where we come in! Our team of renewable energy management experts are here to help! We know that no two homes are the same and that is why we provide an energy solution that is unique to you and tailored to how you use your electricity.

RENEWABLE ENERGY
Generate your own energy.
So you can rest easy knowing that you are doing your bit for Climate Change and are well on the path to Net Zero.

BATTERY STORAGE
Store what you don't use.
Battery storage allows you to store the energy that is not being used for a time when you need it. Couldn’t I just sell my excess energy for extra income? Yes, however, the rate that you sell the energy back to the grid for is often rather low. For example;
You can sell your excess energy back to the grid at a rate of 7p a unit. However, when you return from a long hard day and sit in front of the TV you are consuming electricity at a rate of 34p a unit. With battery storage, you now can use that energy generated earlier in the day and keep it for yourself.

Family of 4: typical 9-5
This example is based on the typical 9-5 family household of 4 (2 Adults and 2 Children). Typically the adults and children are work/ school between the hours of 9am and 5pm this is when your solar panels are most effective and generate the most electricity, which is then stored in the battery for a time when you need it most.
A 4 kWh array of solar panels and 10 kWh sonnen battery have been used in this example.

The new normal - working from home
Working from home means that you’re consuming more electricity during the hours you would usually be working. Combining renewable energy and battery storage to generate, use and store electricity means the amount you consume from the grid decreases and your energy bills decrease.
This real life scenario highlights the savings of a residential property in the UK where three adults are working from home with a sonnen battery 10 and a 4 kWh Solar PV array installed. This household represents a high volume of consumption with 4,000+ kWh consumed during this period.

2 RETIRED ADULTS
The below scenario is taken from two retired adults in the United Kingdom. Retirement allows individuals the chance to relax and unwind with family and friends, and often this impacts the amount of time spent at home. The example below demonstrates the impact a 4kW PV solar array and 11kWh sonnen battery can have on mitigating the impact of increased electricity bills.
