What Affects the Cost?
System size (measured in kW) is the primary cost driver—larger systems cost more upfront but generate greater savings. Roof condition and pitch affect installation complexity; weak or south-facing roofs may require reinforcement. Electrical upgrades, such as new consumer units or underground cabling, increase costs. Distance from the grid connection point, local building regulations compliance, and inverter type (string vs. hybrid) all influence final pricing. Dunstable's location in Bedfordshire offers good solar irradiance, making most installations viable.
Money-Saving Tips
Get multiple quotes from MCS-accredited installers to compare system designs and warranties. Consider a smaller system now with battery storage later—battery costs are declining rapidly. Check eligibility for government VAT exemptions on retrofit systems and the Smart Export Guarantee to offset installation costs through energy sales to the grid.
