Bi-facial solar panels

SOLAR PANELS USED BY SOLARIGO

As a new innovation, Solarigo offers its customers the opportunity to purchase double-sided solar panels. The solar panels' own 21% efficiency, added to the 6% added by the two-sidedness, is a total of approx. 27% efficiency. The benefit is greatest when the background of the panel is as reflective as possible, such as white paint, light sand or snow. Ask our sales team for more information.

Panel systems that follow the sun

SOLAR PANELS USED BY SOLARIGO

With systems that follow the sun, it is possible to increase the power plant's production by up to 60% in summer. However, a rack that rotates around two axes consumes electricity and requires significantly more maintenance than a static installation. In practice, the increase in production would be around 30%. Taking into account the more expensive price of the stand, it is profitable to install a swivel stand solution only in places where the available space is very limited, but at the same time the greatest possible production is desired.

The rack, which rotates in the direction of one axis, enables more even electricity production around the clock and better production in cloudy weather. In this case, the better production of the rotating panel is combined with the operational reliability and cheaper price of the more static panel. Were you interested in rotating panels? Ask our designers for more information.

Solar panel alignment

SOLAR PANELS USED BY SOLARIGO

Naturally, solar power plants are always designed to be as productive and profitable as possible. In Finland, annual solar radiation on a horizontal surface in southern Finland is about 980 kWh/m2. By orienting the panels at an angle of approximately 45 degrees towards the south, the amount of usable radiation can be increased annually by 20-30%.

The production of the solar power plant can be equalized for different times of the day or during the summer months by orienting parts of the power plant to the southeast or southwest. As a rule of thumb, by orienting the panels to the southeast or southwest, the production decreases by about 7% and to the east or west by about 20% of the production of a system oriented directly south.

Can the power of solar panels vary?

SOLARIGON KÄYTTÄMÄT AURINKOPANEELIT

The power of the solar panel can vary. Solar panels installed on roofs are usually less powerful than panels used in large ground installations. In roof installations, the solar panels have a power of about 360 Wp (Wattpeak, i.e. peak power), an open circuit voltage of 30–40 V and a short circuit current of 9–13 A. In large ground installations, the panels are generally more than 500 Wp.

By connecting the panels in series, the voltage level can be raised to 1,000 V or even 1,500 V. Voltages of more than a thousand volts are practically only used in ground installations of industrial size.

Installation of solar panels on the roof, wall or ground

SOLAR PANELS USED BY SOLARIGO

Roof mounted solar panels

A solar power plant installed on the roof is the most common solution in local solar power plants, because the roof surfaces are often not actively used. The solar panels can be installed on a flat or ridged roof and on different surfaces such as a felt roof or tin roof. In ceiling installations, the angles of the panels are usually 15–30 degrees. In summer, a low-angle panel produces better electricity than a vertical wall installation. In cloudy weather, even indirect solar radiation is produced better with a low-angle roof or ground-mounted panel. The benefit of roof installation is on the one hand the utilization of the wasted surface area of the roof, on the other hand the challenges to be solved are the adequacy of the surface area, the orientation of the panels towards the sun and the durability of the roof.

Ground-mounted solar panels

In land installations, the solar power plant is installed on land that has no other important use. The power plant can be installed on flat terrain or gentle slopes. Ground installations are preceded by ground leveling. The advantage of ground installations is that you usually get to use a larger surface area, which means that the panels can also be placed at an angle that is optimal for electricity production (close to 45 degrees). A challenge to be solved in ground installation is reserving a suitable land area for the solar power plant.

Wall mounted solar panels

Wall-mounted solar panels are less common, but a possible solution. The wall panels are on the wall at an angle of 90 degrees, so the production is better in the autumn and spring months, when the sun is low and the snow does not settle on the surface as easily. The advantage of wall installations is that the wall surfaces of buildings often have no special function, and the challenge to be solved is that the installation work is often slower and a bit more expensive.
