FAQ about solarpanels

What is a solar panel?

A solar panel or PV panel (from the English “Photo-Voltaic”) is a panel that convert solar light into electricity. For this purpose, a large number of photovoltaic cells is assembled onto a panel. Our Solar cells are made from silicon, the most important part of a conventional photovoltaic cell is the piece of semi-conductive material which contains an interface between p-type and n-type doping (photo diode), the electric current can only pass through the solar panel in a direction. If there is sun light (electromagnetic radiation) is incident to the solar cell, electrons are released. Thus start to move in the desired direction. The movement of all detached electrons together, the electric current that runs through the solar cell. A solar panel supplies DC power. It can be connected to a converter to get AC. The multiplication of the voltage of the cells with the current intensity, the power of the solar panel yields.

What is the difference between mono and poly panels?

Polycrystalline silicon, and silicon are monnokristallijn namely both made from the same raw material silicon sand. The difference is in the editing process of the silicon sand. When single crystal silicon is one, in contrast to the polycrystalline silicon, to affect the polarization of the crystals during the solidification, so that they all come to lie in the same direction. Monocrystalline solar panels giving a slightly higher efficiency, longer, but are more expensive. The quality and the guarantee for both mono- and poly panels are identical. We offer a 10 year product warranty, also we give to 10 years 90% power guarantee and even after 20years 80% power guarantee.

Solar panels work even on cloudy days?

Our solar panels are also effective in cloudy weather, of course, with a lower yield. Clouds only a portion of the sunlight. In addition, the yield of solar panels is dependent on several factors: loction, placement, angle of inclination, etc. etc.

It’s important to minimize shading because solar panels operate at optimal output when their entire surface is fully exposed to direct sunlight. The system will still produce energy if it is shaded but its output will lessen.

What cost solar panels?

The cost of a complete system with panels composed of several elements: type of solar panels, solar panels quality, number of solar panels, inverter, wiring, mounting frame, installation costs and any other costs such as meter adjustments. The assembly of solar panels on a flat roof is also generally cheaper than on hell duck roof such as a tiled roof. Even more important than the cost, the yield of the solar panels and the associated payback. Only then can you determine what produce solar panels in places they cost.

What does the term watt peak mean?

Watt peak (Wp) is a metric to indicate the maximum power of a device or installation. For example, in the case of photovoltaics, it is the unit that is used to indicate the ability of a solar cell or solar panel.

It is measured internationally established standards:

  • of the light strength, 1000W / m2
  • direction of the incident light
  • solar spectrum (air mass)
  • Temperature: 25 ° C

The Watt peak value is used to compare solar panels together.

With an irradiance of 1000 watts per square meter, this means that a solar panel of 1 m² has a capacity of 100 to 170 watts peak. Our solar panels have a maximum power of 270 watts peak, which is 170 Watt peak per m2.

What is an inverter?

A power inverter, or inverter, is an electronic device or circuitry that changes 12 volt direct current (DC) to 220 vol alternating current (AC).
