Roof Solar Panels
Introduction to Roof Solar Panels
The popularity of alternative energy sources is increasing as more and more people are looking into ways that will save them money on their monthly bills. When it comes to finding better methods of generating electricity, one option sets apart from all the others: roof solar panels. This technology appeals to many homeowners as it generates power in a convenient, long lasting form, most solar panels being built to last for approximately 25 to 30 years.
The Location of Roof Solar Panels is Important
Roof solar panels need light from the sun in order to meet their purpose, therefore, prior to installation, finding the best location is highly important for gaining as much electricity as possible. Roof solar panels need to be placed in such a way that they get plenty of sunlight, so if you live in the northern hemisphere, the roof side that will comprise the solar panels has to face south.
Types of Roof Solar Panels
Aside from the obvious differences in manufacturing companies, size and shape, there is also a significant difference when it comes to solar panels that are placed on top of the roof. Thus, there are regular roof solar panels that are mounted on the roof’s shingles, and there are also solar roof shingles that not only protect the roof, but they also generate electricity.
The former technology requires a larger investment compared to regular roof solar panels as the cost of solar shingles is higher per watt, the exact expense depending on the providing company, on the size of your system and the amount of work you’re willing to do as solar roof shingles can be installed by regular homeowners who have the skills and the knowledge of handling this type of challenge.
The Advantages and Disadvantages of Roof Solar Panels
One benefit of having roof solar panels installed on top of your house is that this technology is meant to last for years and years to come. The process of producing energy is completely silent and ecologic, and the use of this alternative source of energy will save you money in the long run. Roof solar panels require very little maintenance, and they also provide shade for your roof, resulting in a slightly cooler attic.
The disadvantage of this kind of technology is obvious if you’re planning to move. If you do intend to leave your house, you won’t be able to take the solar power system with you. Also, the amount of electricity generated through the sunlight will never be 100%, therefore homeowners usually integrate roof solar panels as part of a bigger system, backed up by additional batteries, wind turbines and an emergency generator. Not to mention the fact that this technology is completely based on the sun. If you’re planning to do some roofing work, you will need to remove the solar panels and remount them, this activity requiring additional costs and effort. Although pretty durable, some roof solar panels might not stand a chance against a serious hail shower so make sure you purchase a residential solar power system that is anti-hail resistant.
When it comes to roof solar panels, there will be always ups and downs, yet the continuous advancements in the field make them an appealing offer for many homeowners.
