The best area to place solar panels at home is one where the exposure to sunlight is the maximum. That is why the covers, whether flat or inclined, are the right solution, especially if they are free of obstacles and shadows.
The optimal conditions occur when the photovoltaic solar panels are placed facing South and with an inclination of approximately 30º. However, if the conditions are not optimal, it is still profitable to install photovoltaic solar panels. In this way, you will see how your electricity bill decreases, your savings increase, and your carbon footprint is drastically reduced.
In the hypothetical case that the roof of your house is not suitable for installing solar panels, you can always fix the land available on your property.
In other countries, there may be geographical areas where it is not unusual to install solar panels at home
To obtain optimal conditions, the roof must face the South. If your roof is oriented in an East or West direction, there would be losses due to orientation of between 5% and 15%. Even so, with your solar panels for self-consumption in your home, you will continue saving on your electricity bill and helping the environment.
To place the photovoltaic solar panels in your home, the inclination of your roof must be between 15º and 45º. In case your roof is flat, it is necessary to place structures with a suitable angle of inclination.
Cover size and shape
Regarding the shape, you can say that to put solar panels in your house, the more regular and square, the better the cover. Concerning size you can use the approximation shown in the table:
In a detached house with 40 m2 of the roof, you have more than enough space to install photovoltaic solar panels for self-consumption.
When determining the size of the roof, you should not consider obstacles such as elevator shafts, attics, fireplaces, and air conditioners.
Whenever possible, you should put solar panels at home in shadow-free areas. Usually, it is the trees and adjoining buildings that cause shadows on the roof at some time during the day. Although you can’t do anything with buildings, trees can be pruned to reduce the effect of the shadow, which in turn causes environmental benefits. To avoid this, it is best to hire an experienced solar panel installer and guarantees like the ones we have at Solar company Tucson.
The lifespan of photovoltaic solar panels is 25 years or more. Conveniently, your roof is in the conditions that allow it to last at least the same as the installation of solar panels. If your cover is not in good condition, it is recommended to perform a ratcheting before the solar installation.
Types of tile
The photovoltaic solar panels are compatible with almost all types of roofing, including tiles are wood, concrete, composite, tar, gravel, slate, and metal. Clay, wood, and slate tiles are less resistant and, therefore, more prone to breakage.
