Embracing solar power technology is a practical and cost-effective way for you to join the sustainability revolution, ‘go green’ and cut the cost of your power bill. Putting a solar photovoltaic array (or solar panels) on your roof means energy particles from the world’s never-ending supply of sunlight are turned into power you can use that is also sustainable, clean and non-polluting.
Are solar panels suitable for my roof?
“Solar panels are rugged and durable, but are they suitable for my home?” This is a common question asked by many people who are considering ‘going solar’.
The answer is almost certainly “yes’”. Modern solar panels are designed to be fitted to almost every type of roof, from completely flat to very sloping. So whether your home is brand new or your roof is quite old, installing solar panels will actually help to protect it for a long time into the future. The panels are designed to last for several decades and, at the same time, they will shield and protect your roof from ageing damage caused by light, bad weather and heat. In fact, solar panels can produce a roof insulation effect, regulating the temperature in the rooms directly below them and further cutting down your heating and cooling costs.
How heavy are solar panels?
Others wonder if the installation process of putting solar panels on their roof might damage their roof, causing leaks and letting water in when it rains. But installers are highly qualified and pay special attention to ensuring that the panel installation is not only sound but completely waterproof, using sealants and other materials to protect your roof and home.
So even if your roof is old, solar panels are not heavy enough to cause it any problems. On average, the panels plus any mounting equipment will not weigh any more than between 10 – 20 kilograms per square metre, which is light enough for your roof to easily support – and much lighter, for example, than the weight of a person walking on the roof. Installers will also take care to distribute the weight evenly across the array when installing your panels.
