For the majority of homeowners in Cheltenham solar panel installation is a long-term commitment and until now homeowners have struggled to get a clear idea of when the numbers will start to work in their favour.
Typical Payback Period
A typical domestic solar panel system will take around 8-12 years to repay its initial outlay in full. This repayment time is determined by a number of factors including; the size of the solar panel system, the purchase price of the system, and the amount of the electricity which is actually used by the homeowner.
Reducing Your Electricity Bill
How Solar Can Cut Your Annual Electricity Bills. For most people the core benefit of solar power is reducing their annual bills by paying for the electricity they generate with the electricity they generate. This saving can amount to up to £700 in a year for a typical 4kW solar panel system.
The Smart Export Guarantee
Exported energy is paid for by the utility company at rates typically between 4p per unit (for band 1 tariffs) and 15p per unit (for band 3 tariffs), paid by the supplier chosen by the installer. Smart Export Guarantee rates vary by tariff.
Adding Battery Storage
The money in your pocket with a battery, as it can save you up to £200 – £400 a year, by using energy you would have otherwise exported or lost, at the relevant evening grid rate.
Long-Run Degradation
However, panels do degrade over time with around 0.5% fall in production each year. In twenty years time a quality installation could fall to around 90% of original output but still provide very good returns in the long term.
