Understanding the numbers
When we do your free survey we'll provide you with a full breakdown of the numbers and explain everything.
But for now, let's look at an example estimate to understand the headline numbers.
Number of solar panels = 16.
The more panels you can fit on your roof, the more electricity you can generate,
the more money you can make.
Size of system = 4 kW.
A 16 panel (4 kW) system is estimated to produce 3,400 kilowatt hours of electricity per year.
This would satisfy the needs of an average household.
Cost = £5,985.
This is the total cost, supplied, installed and certified. There are no hidden extras.
VAT is only charged at 5% as it's a green product.
We feel it's important to let you know that the inverter will last about 10 years
and at that point you will need around £800 to replace it.
Electricity bill savings per year = £260.
This is based on the assumption that you use half the electricity that you generate.
Remember though, you are allowed to use all the electricity you generate during daylight hours for free,
and if you do the higher your savings will be.
Total financial benefit over 20 years = £22,200.
This is the sum total of your income plus your savings.
We are members of The Renewable Energy Consumer Code (RECC)
and follow their strict code of practice to calculate your financial returns.
This code is backed by the The Trading Standards Institute.
This income is tax free for homeowners.
Total financial benefit per year = £1,100.
So on average, you'll benefit by over £1,000 tax free per year.
Payback time of your investment = 6.5 years.
This is the estimated time it takes to pay back your investment.
So, in this example, it's 6 and a half years to pay back your initial outlay,
then the income in the next 13 and a half years is clear profit.
Average return on your investment per year = 14%.
This is based on the whole 20 year period, and is the average rate of return you'll receive per year.
