You need to make sure you replace the solar inverter every 10 years or so, which will leave you around £1,000 out of pocket, unless you want your whole system to go kaput.īy keeping your solar panels in pristine condition, you can increase their efficiency by up to 3-5%. Solar panels are relatively low maintenance. So, if you’re after the more affordable renewable energy, stick to solar power.
The typical cost of a 2.5kW system is between £9,900 and £19,000, whereas a 6kW system will cost you between £21,000 and £30,000. The energy capacity of each turbine will also add to its price. Since building-mounted turbines need to sit comfortably on a roof, they also need to be much more dainty – meaning they’re unable to generate as much energy as their pole-mounted acquaintance. Of these two turbines, building-mounted turbines are cheaper – but as with most things, a cheaper price tag can mean a less efficient product. Pole-mounted turbines are free-standing and must be in a high up, exposed area, whereas building-mounted turbines are much smaller and can be installed on the roof of your home. The cost of wind turbines fluctuates much more than solar panels, since you have two options to choose from: pole-mounted or building-mounted turbines. The type of solar panel you’re going for.
Solar panel costs also fluctuate depending on: In fact, according to Which?, the average price for a 4kWp solar panel system before 2015 was more than £9,000, compared to the average cost of £6,600 in 2018.
Solar’s rising popularity has led to a gradual decrease in price over the past decade. The average cost of a solar panel system for a three-bedroom house is £5,420, whereas a wind turbine can cost anywhere between £9,000 and £30,000. However, solar is much cheaper upfront, and is typically lower maintenance. There’s no denying it: both of these options can strain the purse strings.
