Solar panels on the roof produce electricity that can be used directly in the house or building, before any surplus is supplied to the grid for use in the neighbourhood.
With solar electricity, you are a micro-generator of green electricity from a renewable energy source and contribute to a better environment while making a good investment. Solar electricity from solar cells always produces a significant surplus regardless of what heating you already have, wood burning, direct-acting electricity or district heating. The best solution is solar panels combined with a heat pump of some type.
When you produce your own solar electricity from solar cells, you produce renewable energy without any emissions, and without having to worry about rising electricity prices.
The cost of solar cell packages has fallen dramatically in recent years. Global demand has increased significantly and the production of panels with solar cells has been rationalised. In Europe, it is above all Germany and Denmark, where electricity prices are expensive, who have driven the development of solar panels. Thanks to this the cost of solar cell packages has fallen to a completely different level and has also become extremely interesting for the for the rest of the European Market.
In brief: the sun's rays hit the solar cells, they generate energy in the form of electricity (direct current), which is converted via an inverter into alternating current. The inverter is the only component of the solar cell package that is not located on the roof. It is positioned in a suitable location e.g. in an attic space, utility or boiler room and connected to the house's normal electrical distribution board, which in turn is connected to the grid. A solar electricity system does not require any water and, therefore, neither does it need an accumulator tank nor a pump station.
The electricity that the solar cells produce always takes the shortest route to the user. This means that it is primarily the house itself that uses the solar electricity produced by the solar panels. Any eventual surplus can be stored in batteries or sold to the national grid. From there, the solar electricity is used by your closest neighbours when they purchase electricity from their supplier.
The amount of kWh that can be produced by solar electricity depends on the geographical location, the number of solar panels, the angle of the roof and the weather. The output can also be affected by shade from trees, flagpoles, TV antennas etc. The solar panels are mounted on the roof with roof mounts and aluminium rails, which are included in our basic kit. Our solar cell package is suitable for houses and buildings with tiled roofs, sheet metal roofs, seamed sheet metal roofs and felt roofs.
Generally speaking, it is estimated that solar electricity production yields approximately 1000 kWh in the north, up to almost 2000kWh in the southernmost regions per kW solar cell package annually. However, the sun shines more or less, at different times during the day and the year, while electricity consumption follows its own pattern.
The proportion of solar electricity that is used directly in the home is ”free”. The saving is equivalent to the sum of the usage based costs of electricity. The solar electricity that you do not use yourself instead turns to income through sales.
Choose an electricity retail company with care, to ensure that you get a good deal for both the electricity sold and the electricity you need to buy. A house uses roughly half of the solar electricity and the other half is sold to the national grid. The fraction of energy sold increases with the size of the solar cell package.
Your NIBE solar cell package is estimated to last for at least 25-30 years, which is often as long as the roof tiles will last.
Do not clean your solar panels. There is a risk of scratching the glass. Let the wind and rain do the job. Do not remove snow from the panels if the roof itself doesn’t need the snow to be removed, it usually slides off by itself.
On an annual basis, you get the best possible benefit from your solar cell package when it is used together with a heat pump. The heat pump's energy consumption is often halved when supplemented with solar cells. Here are two examples for Swedish conditions:
A newly built house of 150 m2 with exhaust air heat pump NIBE F730 and a solar cell package of 3 kW. The heat pump's annual electricity consumption of approximately 6000 kWh is reduced by approximately 3000 kWh in northern Europe with the solar cell package, which gives a total consumption of only 3000 kWh/year.
An older house with an energy consumption of heat and hot water of approximately 27,000 kWh. After installation of the ground source heat pump NIBE F1255 and a 3 kW solar cell package the combined consumption is just over 3000 kWh/year in northern Europe.
NIBE is a package supplier of complete solar cell packages and we are continuously working to develop efficient and sustainable system solutions for your energy needs. Solar cells combined with other heating systems are one of the best investments you can make both for the environment and your personal finances.
The solar cell packages is available with five different basic outputs; 3, 6, 9, 12, 15, 18, 21 and 24 kW. A basic kit has ten panels. Panels can be added or removed in order to achieve a better and more attractive roof installation. This is what we call standardised flexibility. With the solar cell package you can use 10–80 solar panels and obtain 3–24 kW. For anything larger, we can be multiplied to the desired output. The solar panels can be mounted on most types of roof such as tiled, sheet metal, seamed sheet metal and felt roofs.
Solar cell packages contain
The solar panels are made of monocrystalline silicon cell panels using PERC technology for better performance in heat and low light with an output of 300 Wp. When the sun shines on the solar cells, they utilise even the smallest amount of sunlight and convert it into electricity. PERC technology is standard in our solar panels for the best results and the highest quality. The panel frame is black, is made of rigid anodized aluminium and meets the highest standards for stability and corrosion resistance. The areas for the basic packages are: 16,5 m2, 33 m2, 49,5 m2, 66 m2, 82,5 m2, 99 m2, 115,5 m2 and 132 m2 in each basic kit. The inverter has dual trackers enabling multiple strings and the solar system can be monitored using the NIBE Uplink app and the NIBE controls.
If you have another NIBE product that is supported by the NIBE Uplink app, it is possible to connect the solar panels. Uplink can give you a quick overview and the present status of solar cells on your property. You get an easy-to-grasp view, where you can follow and control the heating and hot water comfort.
