Reduce Energy Bills - Solar Panels, Battery Storage and Avoiding Peak Time Usage.

Potentially your future dwelling could be 50% cheaper to run and 100% more sustainable thanks to a clever and innovative mix of solar, home storage batteries and computer software that will enable these systems to integrate seamlessly into your every day life.


Solar and battery-storage technologies are nothing new, it is the integrated software management systems that bring the real innovation. Due to the economies of scale driving down prices they are becoming more easily attainable for the man on the street. Great news for the would be energy saver and the green movement.


The basic system set up will include a solar/thermo panel system and a home-battery. The battery is charged directly using DC from the solar array, but an inverter will be required to facilitate movement of power between the battery and the grid. A software Management system will be necessary to decide how best to manage the generation and demand at any given time. Additionally to this, the management software may extend its reach to the control of E.V. charging and the use of other appliances around your home.


There are several ways financial savings can be achieved:


Solar and Battery Storage

The majority of the savings will likely come from you as a consumer, using more of the energy you produce from your solar panel system. Although solar panels provide return on investment by off-setting your normal energy bill and from the FiT, you generate most of the energy during daylight hours, when you are more likely to be out and unable to benefit from ‘free’ electricity. Consequently this power is exported to the grid and you receive payment of, for example, 5.24 p/kWh from the FiT scheme. When you arrive home and your household demand increases, you buy this power back at an increased rate of around 12.5p/kWh. This poses the question, who is benefitting most? This is where battery storage comes into it’s own and sways the benefit back in your corner. This will be even more significant when FiT payments stop in April 2019 as using stored energy and drawing less from the grid will make up for the loss of the tariff payments.


Avoiding peak times

Energy costs the most exactly when you want to use it, naturally, but the following tip will help you avoid using power at peak times.

If you charge your home-battery directly from the national grid at night time, when the price of energy is lower, then you can draw from this reservoir of cheaper stored power during the mornings, therefore allowing you to avoid the increased price. This method is referred to as ‘peak shaving'. This helps the energy network manage peak demand, whilst allowing energy produced by wind turbines at night, to be stored and used, instead of wasted. It should also reduce, ‘shave’ money off your energy bills.
