Dispelling the Myth:

While the upfront cost of installing solar panels may seem daunting, it’s essential to understand the long-term financial benefits and the factors that influence the overall cost.

Understanding Installation Costs:

The cost of installing solar panels can vary based on several factors, including your location in the UK, the chosen installer, and the type of panels selected.

Longevity and Maintenance:

Once installed, solar panel systems are designed to last for approximately 25 years with minimal maintenance required. Manufacturer warranties typically cover any faults that may arise, providing peace of mind to homeowners.

Inverter Replacement:

It’s important to note that the inverter, which converts direct current (DC) electricity generated by solar panels into usable alternating current (AC), may need replacement after 10 to 12 years. The cost of replacing an inverter averages around £800, depending on system size and manufacturer.

Financial Incentives:

Celtic Green Energy provides tools such as the solar panel calculator to help homeowners estimate installation costs and potential savings. Additionally, through initiatives like the Smart Export Guarantee (SEG), surplus electricity generated by solar panels can be sold back to the grid, further reducing energy bills and accelerating the payback period.

Factors Influencing Savings:

The amount of money saved on energy bills and the payback period for installation costs depend on various factors, including roof orientation, geographic location, and household energy usage patterns.
