With the energy crisis in Europe and the Canadian government subsidizing the installation of solar energy, don't you want to install a rooftop solar energy? Commonly, there are flat roofs, and European pitched roofs. What kind of solar energy is suitable for European pitched roof?  Do you know around 300watt solar panel for european roofs is the best choice? Why? Let’s see together!

Ⅰ. Why are most of European roofs pitched roof, not flat roofs?

Most of the European roofs are pitched roofs. The main reason is both drainage and aesthetics. On the one hand, the climate of most of the European region within the temperate oceanic climate, temperate continental climate. This climate is characterized by the temperate zone is dominated by the influence of the sea, mild and rainy throughout the year. The United Kingdom, for example, rainfall throughout the year and evenly distributed, no rainy season dry season, the climate is mild, in which the rainy season of up to 113 days a year, an average of every three days is a day of rainy weather. Then their houses are designed as sloped roofs, which are naturally conducive to drainage, there is no platform on the roof, there is no water storage space, drainage is smoother, and it will not cause water seepage and leakage, cracking and other problems after living for a long time. Flat roofs can not provide this function. On the other hand this kind of roof designed as a slope looks more beautiful and stylish in design than flat roofs.

Ⅱ. How to select suitable solar panels for European pitched roof?

Suitable solar panels for European pitched roof need to fulfill the following characteristics

A. High cell conversion rate, sufficient for domestic power generation

The conversion rate of the batteries determines how much power the incoming light will be converted into for household use. The original purpose of installing rooftop solar for homes is to reduce the cost of electricity. Therefore a certain quality of solar panel is required. Currently there are three popular battery technologies: HJT, TOPcon, and PERC, and the conversion rate of the batteries decreases in turn. the conversion efficiency of TOPcon batteries is higher, although lower than that of HJT batteries, but higher than that of PERC batteries, and belongs to the intermediate product, which is able to reach about 22%. It is very suitable for European rooftops to generate electricity.

SUNKEAN's three types of around 300watt solar panels specifically designed for European rooftops all use TOPcon battery power generation technology, and the conversion rate of power generation is around 22%. They meet the demand for high power generation.

B. Lightweight

Unlike installing solar panels on the ground and on flat roofs, general European pitched roof do not have the space to assemble each solar panel into a system on the roof and need to climb up to the roof to install the solar panels. So if the PV panels are heavy, lifting them onto the roof can be a challenge, especially if you are working independently. Generally as a rule of thumb, full size panels weigh between 18-35KG, it varies depending on the products used by the manufacturer. Solar panels suitable for installation on European pitched roof are generally chosen to be fine at less than 25kg.

SUNKEAN's three around 300watt solar panels specifically designed for European rooftops all weigh less than 20kg, are lightweight and have a conversion rate of around 25%. The 240w solar panel size is 1152 x 954 x 30 mm with a mass of 11.5kg, the 280w solar panel size is 1336 x 954 x 30 mm with a mass of 13.2kg and the 340w size is 1616 x 954 x 30 mm with a mass of 16kg.

C. Medium size

Roofs are different from floors in that the installation area is limited. Especially on European pitched roof, because of the inclination, the area for installing solar energy is much smaller than on flat roofs. Therefore, the choice of large size panels is not suitable for installation on European roof buildings, generally choose the size of less than full-size solar panels are more suitable.

Traditional solar panels come in two common configurations: 60 and 72 cells. The solar cell is the smallest unit of photovoltaic conversion, and the common size is usually 156mm x 156mm. The operating voltage of a solar cell is about 0.5V, and it cannot generally be used alone. When solar cells are packaged in series and parallel, they become a photovoltaic module. A single solar cell is a 156mm x 156mm square. 60 panels are arranged in a 6x10 grid. 72 panels are arranged in a 6x12 grid and they are about 3 to 4 centimeters high.

SUNKEAN's three types around 300watt solar roofing panels for Europe are 60, 70 and 85 respectively, so you can choose the right size of roofing panel according to the usable area of your roof.

D. Moderate power: around 300 watt solar panel and 400watt are the best choice

At present, the household PV market generally uses high-power modules, such as 490w, 535w, 550w and other models. The use of high-power modules in the limited roof space improves the utilization rate and increases the power generation revenue per unit area. But at the same time the power is determined by the number of cells in the panel, the higher the power, the larger the panel size will be. Obviously, the above high power panels are not suitable for European pitched roof.

The profitable area of the roof determines how much capacity of PV power plant you can install at most. According to the current power calculation of PV parts, you need about 8 square meters to install 1kw; if you want to install 15kw PV power plant, you need about 100 square meters of roof area.

Medium power solar panels, such as around 300 watt solar panel and 400watt solar panel are recommended for installation on European pitched roof. SUNKEAN's three types of solar panels for European rooftops are corresponding to round 300 watt solar panel or 400watt solar panel, Their power is 240w, 280w, 380w respectively. They are suitable for being installed on European pitched roof.
