The cost of solar panels
To put this into more relatable figures, to power a standard three-bedroom house in the UK, you’ll need a 3-4Kw solar system which will set you back between £5,520 and £6,040 for installation. In addition, this will need at least 20 square metres of suitable roof space for a 3Kw system and 25 square metres for 4kw. In terms of the returns on investment, for a 4Kw system you can expect to be paid about £79/year by feeding your excess generated electric into the national grid. Combined with the savings to your existing energy bills, a standard repayment time is between 13 and 17 years in the UK. Given that the lifespan of solar panels is between 25 and 30 years, this will provide you with a conservative estimate of 8 years of profit, with a potential of up to 17 years!
Carbon emission savings
From an environmental perspective, this 4Kw solar system will be avoiding the release of around 1.5 tonnes of carbon dioxide yearly. This reduction of carbon emissions combined with the growing financial savings on offer makes the prospect of renewable energy more appealing than ever before. For this reason, with current predictions, the installation of these blue silicon panels will become more and more common as we head into the next decade.
