Solar panels are large panels that contain a number of solar cells. These are the most common option when it comes to designing a solar system for a home or for any other type of property. They allow for the use of many solar cells, are fabricated off site for easy installation, and come in a variety of dimensions.
You can choose whether to have your solar panels fitted on top of your roof or have them built into the roofline. Those that sit on top of the roof are less expensive but they do protrude from your existing roofline. Integrated solar panels, on the other hand, will cost more because they will require a new roof in most cases but they look less conspicuous once they are on your roof.
Another alternative is to have solar tiles or PC tiles installed. These take the place of typical slate tiles and while they are usually a little larger than slate tiles and fit against one another they can provide the best looking solar option. Except under close inspection they are barely noticeable which means that you can still enjoy a good looking roof while also benefiting from having a solar system in your home.
An average system will usually cost between lb10,000 and lb12,000 but you should expect to pay more for larger systems and those that use more advanced features. Similarly, if you only have need for a smaller system you may not have to pay as much as this and prices will vary depending on which fitter you use to have your solar panels and solar system installed.
