Many homeowners in the UK are considering the value of adding solar panels to their property. But this technology seems to be in a state of constant evolution and there are many common questions or conditions that homeowners need to ask before jumping into this project.
Without getting into too much detail, here are the basics of residential solar panel installation and product selection.
Will Solar Panels Be Effective in Typical British Weather?
It's a common misconception that solar panels require massive amounts of sunlight to be effective. In fact these products collect energy from the daylight, which is an important difference. The typical weather in the UK at all times of year will provide plenty of energy to make a solar panel installation worth it.
Will the Panels Affect the Overall Stability of the Roof?
Although there may be issues with panels that have been improperly installed on aging roof systems, for most solar energy systems the answer is no. They are lightweight and designed to be mounted without a problem on homes of any size and age.
Does the Roof Material Need to Be Removed Before Installation?
Solar panels can be easily installed as a flush fit on new builds and with extensive renovation on older homes, but the systems are designed to work well as a surface mount. In that case the roofing materials can remain as they are and the panels will be fitted on top.
Is It Necessary To Have Planning Permission?
It depends entirely on where your home is located, but in general a trip to the Local Building Control will help you to find out. In certain areas where conservation is a concern the panels may need to follow specific guidelines and be designed a special way, but in most other cases the standard systems work fine.
Do the Panel Systems Need to Cover the Whole Roof to Be Effective?
The amount of power you want to collect will determine the size of your panel system. A basic panel is usually 2m long and 1.5 wide, although that can also vary by the manufacturer. Many UK residents start small with just a few panels and then build onto the system as they gain confidence in the technology.
How important is Location?
Where you mount the solar panels is extremely important, as they need to be facing south in order to capture the most daylight and be the most effective. South, southeast or southwest facing panels are recommended and no major barriers should exist in that line of sight.
Consider installing the panels on a frame in the garden if there isn't a clear line of sight from your rooftop.
