How Solar Battery Storage Is Sized for Cheltenham Homes – Too Small is Throw Away Money, Too Big is Bins of Money that Never Gets Spent.
Daily Consumption Drives the Calculation
Now we have an idea of your daily consumption, we need to work out what size of a battery will meet your needs. The daily average of your annual household usage is a good starting point for calculating the right size of a battery for your home.
Your Solar Array Sets the Ceiling
The capacity of a battery is only limited by the amount of power your solar panels can generate during the day. As previously stated, a typical sized roof for a semi in Cheltenham (3-4m wide) would have a 4 kWp array on it. The array would produce around 3,400 kWh of electricity each year.
Usage Patterns Can Push Capacity Up
A number of factors influence the required capacity of Solar Battery Storage systems. Factors such as EV charging overnight, high evening demand and Smart Tariff off-peak electricity charging all influence the required capacity of Solar Battery Storage for homes in Cheltenham. The typical amount of usable capacity required to service a family in a typical Cheltenham home is in the range of 5kWh to 10kWh.

Usable Versus Nominal Capacity
10kWh is not the same as 10kWh usable. Typically lithium batteries allow 80% – 90% depth of discharge. Here’s a more detailed overview of the possible ways to size solar battery storage for Solar Battery Storage Cheltenham.
Physical Space Affects Your Choices
Space on walls is a key consideration. There must be clear wall space of about 0.6m² for wall mounted battery storage systems, which have to be within a specified temperature range. Thus, a warm boiler cupboard would not be suitable for some models. Check the amount of wall space available for the units on the market before deciding on a specific product.
Plan for Future Demand
It is likely to be more cost effective to purchase a larger battery now, rather than having to purchase and install a second battery in a few years time when you have added a high draw appliance such as an EV, a heat pump, etc. to your demand.
