What will solar panels and battery storage do for you?

There has been scepticism of solar panels and people do question if it really works!  Callidus has been installing solar since the beginning of the feed-in-tariff and has installed many thousands of systems.

The truth is that solar does work and offers greater opportunities to reduce your energy bills and making you money at the same time.  The below is to demonstrate how solar and battery storage can be a great way to reducing your increasing energy bills and make a profit in doing so. The below is for your information, however, Callidus when visiting your home carries out a detailed survey and asks the right questions, in order for us to build this type of analysis for you.

The graph on the left-hand side shows the typical usage profile of a UK household per month over a 12 month period i.e what we buy from the grid, electricity usage varies from day to day, week to week or month to month.

For instance in the week during the day, your usage will be different to later that night, and again typically that will be true for weekends and when you are on holiday.

According to OFGEM Below table are the typical usage profiles of a UK household in kWh

The below system has been built using PV Sol Premium 2018 which is a specialist Solar specification software designed to show returns or generation and system compliance. The hardware used was eighteen Qcell 290 Watt Solar Panels with a Solaredge inverter and optimisers, facing due South, using the weather data from Meteosyn, using Plymouth Mount Batten weather data, with no shade. The battery is a Pylontech x 3 and using a Sofar AC inverter. The consumption data has been taken from PV Sol and is classed as a typical house usage throughout a 365 day period, using 4000kWh per year at a unit rate of 16pence per kWh.

The graph below shows if you are generating or buying from the grid or storing it:

So you will see from the graph below that it has four main colour coded areas, the grey colour highlights the overall usage of the property and what you would normally pay for if you didn’t have solar. The yellow colour shows the solar generation and self-consumption i.e.  Using the solar power directly into the home when the panels are generating. The blue is what you purchase from the grid and green is what you haven’t used at the time of solar generation and has been sent to the battery to be used later to i.e.  Overnight. 

Energy Storage

Selecting the correct battery for you is vital, you need to be very careful to select the battery that suits your needs. You also need to ensure that the battery is going to last the test of time.

There are a number of home storage battery solutions on the market and Callidus endeavours to only supply the best systems available.
