If you are thinking about installing solar panels in your home, you should know that you will save up to 75% on your electricity bill. Furthermore, photovoltaic installations are very quick and easy to carry out. However, it is normal that you have doubts about how many plates you need to enjoy clean and sustainable energy. At svea solar we help you calculate how many solar panels you need based on the characteristics . How do I determine how many solar panels I need for a home? To know how many panels your home needs, we must take into account various factors that will determine the amount of sunlight that can reach your location. Below, we list each of them: how wide is your roof? First of all, you will need to know how many solar panels you can place on your roof. If we understand that this is an ordinary country house roof, it will be between 40 and 60 m2. Example: let's say your roof has an area of 60 m2 and a solar cell panel has an area of 1.65 m2. So, your roof can accommodate about 36 solar panels.
Calculations: 60 m2 / 1.65 m2 = 36 solar panels how much electricity do you consume per year? Next, calculate how much electricity your home uses each year. This will give you an idea of how much energy your solar panels must produce to meet your current energy consumption. Calculations: 36 solar panels 270 watts 1000 = 9720 kwh in other Phone Number List words, solar panels would produce almost half of all the electricity consumed in your home each year. Calculations: 9720 kwh / 20000 kwh = 0.486 = 49% approx. Quality and performance of photovoltaic panels the quality of the panels is essential for their performance when producing energy. Higher quality systems have a slightly higher cost. However, they make better use of sunlight and are capable of producing more electricity. The higher the quality of the solar panels, the less quantity you will need to install on your roof. Furthermore, as it is an investment, the good performance of the solar panels will pay off the installation more quickly. Type of solar panel according to cell type the technology used when manufacturing the cells of a photovoltaic panel will directly influence its performance.
Depending on the technology used, three types of solar panels can be distinguished: monocrystalline: black in color and rounded corners. They are mainly used to produce solar energy in homes and adapt perfectly to the spanish climate, since they are capable of generating energy with minimal amounts of sunlight. Their cost is high due to their complex manufacturing process, but they retain 80% of their efficiency 25 years after installation. Polycrystalline: they have a lower efficiency than the previous ones, which implies a lower production cost and a more economical price. They also retain 80% of their efficiency after 25 years from their installation. Amorphous: they are the cheapest but the useful life of this type of solar panels is shorter than that of crystalline ones. Installation power the power of the solar panels will indicate the amount of electrical energy they are capable of producing. The total power of the installation is the sum of the power of all the plates that make it up. Calculation: number of plates * power of each panel (wp) = installation power (wp) roof orientation and inclination specifically in spain, the optimal orientation of solar panels is south facing.
