How to carry out its solar installation?
Solar panels are the solution for producing your own electricity for free. Our online site offers you the possibility of installing your own solar panel. Whether you're an individual or a professional, you'll get the lowest price on the market.
To complete this project, you must first measure your roof. You can measure it yourself or use Google Maps. This software allows you to remotely measure the length and width of your roof. Whether you decide to install them on a flat roof or on the ground, the process is the same.
Next, you must choose whether to install them with or without storage. Indeed, solar batteries offer a competitive solution for achieving €0 on your electricity bill. Solar batteries are recharged during the day, when you're away from home, and discharged at night. This way, you no longer use electricity from the grid.
To help you make the right choice, we can guide you through different inverter types and solutions.
How much does it cost for a 100sq house?
Installing a solar panel and producing your own energy at home is possible. You have a 100m² house and are looking to understand how much it could cost? We'll help you better understand.
There are different configurations for installing solar panels. A 100sq house doesn't necessarily mean 100m² of roof space or available floor space. First, you select the location where you want to install your photovoltaic modules. If you can carry out the installation yourself, the cost will decrease by approximately 30 to 50%. If you have the photovoltaic installation carried out by a solar panel installer, the quote may be higher. Also determine whether you want to store your solar energy or not. The choice between a standard inverter and a hybrid inverter influences the final price. With all these technical elements in mind, we can finally give you a precise and reliable answer.
Your 100m² house can be equipped with photovoltaic solar panels at the lowest cost. For a 30sq roof, for example, the cost will be only €6,000. For a 50m² surface, you'll be at around €10,000. The installation price on a 100sq (or 150sq) house isn't a straight line. A solar panel installer can spend the same amount of time installing 20 or 30 panels. This means that the more solar power you install, the lower the price per m² will be.
