Solar Roof Tiles Installation Costs

Material Costs, Labour Fees and Time Frame Estimates for Solar Roof Tiles Installation


Solar roof tiles can be a great option if you’re not too keen on solar panels. Designed to look more subtle, many people love how they don’t appear obtrusive when fitted into the roof. More importantly, they also offer the same renewable energy benefits that solar panels are known for. Many people often have second thoughts when it comes to solar panels usually because of the way they look. This isn’t an issue with solar tiles as they easily blend into the rest of the other tiles very well.

The fact that they can pave the way for lower emissions os carbon and cheaper bills make them a huge plus. It’s important to note though that performance-wise and in terms of costs, solar tiles may not be that impressive as that of traditional solar panels. 

Aesthetically Ideal

Many homeowners these days prefer to go for solar tiles instead of conventional panels due to the fact that they’re more aesthetically pleasing. Solar tiles are also known for offering the same benefits in terms of renewable energy minus the property suffering from the rather ghastly appearance than conventional panels tend to cause. Solar tiles can be used as a roof covering— making them ideal to fit in for those instances when your roof requires replacing. For traditional properties and listed buildings, the only option is solar tiles. 

Straightforward Installation

Getting solar tiles fitted in is a pretty straightforward process. Whichever existing roof tiles need replacing will have photoelectric panels fitted in their place and they look very much like any roof tile. It can take around 2 to 4 days for roof tiles to be completely installed in a typical home.

The installation process usually involves the use of scaffolding and follows the same process involved in a regular roof replacement job. Once installed, the tiles get connected to an inverted where they are then wired and tapped into the property’s electric supply and meter.

It’s important to remember that the roof must be in tiptop shape for roof tiles to be installed. If your roof has rotten battens or damaged timbers, they need replacement first. Other roofing timbers including the soffits, guttering and fascia boards may be best replaced as well especially since the job requires the building of scaffolding to make the most of it.

Also, if it has been two decades since you’ve had your electrical system installed or if your fuse-box is still the old-fashioned one, it would be ideal to include the complete rewiring of your system in the process. Fitting in a new consumer unit isn’t a bad idea either.  

More Expensive Option

Before installing solar tiles, it’s important to remember that whilst they’re really pleasing to the eyes, the costs may not be as impressive especially since they can be very expensive. They actually cost more than regular solar panels. Since they are still a newly-introduced technology, they are not as efficient as regular panels. Currently, they are only about 80% to 90% efficient. Generally, these tiles are often used in many new-build structures where the tiles can just be fitted on the roof even without having any of the existing tiles removed. 

DIY Prospects

People are advised against installing solar tiles on their own. As a new technology, there’s a need to get them fitted only by those who are well-versed about how they work and function. This is to ensure that future problems can be easily avoided. There is also a Feed-in Tariff System which you can be a part of, but to do so, your solar tiles must be purchased from one of their accredited suppliers. You’ll also need to get the MCS certificate of the installer after the work has been completed to process a claim.

Once this is done, you may take advantage of incentive schemes from the government. This entitles you to tax-free payments, which you’ll receive for the next two decades. 

These are non-taxable payments and will also not be counted as personal tax allowance. However, going for cheap tiles which you can probably purchase online and then choosing to have them fitted in yourself will mean you’ll miss out on this particular incentive. Generally, you can get up to £12,000 over the next two decades and that basically pays for the overall cost of a professional installation. So, whilst a DIY option may seem to cost less initially, it may actually end up costing you more over time. 

Costs for Solar Roof Tiles Installation

Average costs on materials for the installation of solar roof tiles will bank heavily on the size that is appropriate for your home. For average properties, 4kw or 3kw tiles may be more ideal to ensure that the energy usage of that particular household gets effectively covered. If there are only one or two people in a property, then the 1kW-2kW tiles would be more than enough.

However, it is important to note that if you ever want to sell the property in the future and a large family is interested in the property, the low capacity solar tiles on your roof might be a hindrance for closing the sale. 

Most roof specialists will charge a daily rate of £100 to £200. They usually do the work with a pair to ensure a timely and correctly done job. They could take about a couple of weeks at the most to get the tiles installed— although the dimensions of your roof will have to be factored in. 

Cost Breakdown

For installing 3kW solar tiles, individual costs could add up to £11,000. Material costs will usually be around £8250, tradesmen fees are £2200, and the remaining £550 is for the scaffolding and waste removal costs
