Large Home Solar PV with Battery in Mansfield.
Larger properties with high occupancy are perfect for solar panels and battery storage. This property substantially reduced their bills with solar and maximised the performance with a battery.
Project Overview
This large family home in Mansfield has 2 large roofs and benefited from the installation of high-efficiency N-type panels by McConnells Green. The system, with a peak power of 15.225 kW, generates over 12000 kWh per year, contributing to 36% of the total electricity usage. With the addition of two 5.3 kWh battery (total of 10.6kWh), this contribution more than doubles to 77%.
Environmental and Financial Impact
The system will reduce the property’s carbon emissions by over 65 tonnes over its lifetime and save more than £77,981 over the next 20 years.
Multiple roofs – One inverter
This property has a main house roof and an separate garage roof. The 2 buildings are separated by a garden and paths. McConnells Green were able to run steel wire armoured DC cabling from the main property to the garage to enable both roofs to be serviced by 1 inverter and 1 set of batteries. This helps to optimise the system performance and saves installation cost.
Sunsynk Max 16kW Single Phase
Most domestic homes have single phase power so accommodating 16kW of power is a big ask. McConnells Green supplied and fitted the largest single phase inverter available worldwide. Combined with a pair of Sunsynk L5.3 batteries this property is ready to take full advantage of the free solar energy.
This level of power also required specialist permission from the network operator which was all handled by McConnells Green.
