It’s also important to note that in addition to the cost of purchasing solar panels for your home, the initial installation cost will need to be factored into your overall cost. However, this can be used to calculate the return on your investment over time.
System Size and Price
To calculate the costs for a solar panel installation for your semi-detached house, a 3-4kWp system is usually the best choice. These systems are usually equipped with a DC inverter, the solar panels and the mountings. For a system of this size you have to expect costs around £5,000-£7,000.
Adding Battery Storage
A home battery will cost £2,500-£5,000 on top of the cost of solar panels depending on the size of the battery which will typically be around the same size in terms of kilowatt hours (KWH) as your solar panel array. The purpose of a home battery is to store the energy that your solar panels are generating during the day, for use at night or on cloudy days when your solar panels are not able to generate as much energy.
Scaffolding and Labour
Scaffolding and the labour to install your solar panels can cost anywhere from £500 to £1,000. Check your quote to see if they are charging for this as a separate item or if it is included in the price of the panels and inverter.
The Smart Export Guarantee
The Smart Export Guarantee (SEG) is another aspect you need to consider when looking at solar panel installation. How the Smart Export Guarantee pays you for surplus energy details how you can receive payments for any surplus energy that your solar panels have generated and exported to the grid.
Getting Quotes Right
Make sure to ask for itemised written quotes for solar panel installation for individual costs for solar panels, the inverter, the mounting equipment, the scaffolding and the electrical work by individual trade contractors.
