Assens Fjernvarme new solar cell/heat pump combination for the the future

Assens Fjernvarme

By combining existing technologies in a landmark way, Assens Fjernvarme, in collaboration with Solar Nordic, has succeeded in drawing a sketch for the green energy production of the future.

Few people are probably aware that at Assens Fjernvarme a heat pump is being installed these days in combination with a 50,000 sqm. The large solar park may prove to be the crucial piece in future energy production and a CO2 neutral Denmark. The complete puzzle consists of a biomass cogeneration plant, a wind turbine, a heat pump, and a solar park from Solar Nordic – all on the same plot.

The four plants together constitute a flexible production capacity that optimizes the production of heat and electricity in an economical and sustainable way.

Green transition now and for the future

It is estimated that the new solar park will be able to reduce the need for biomass by approx. 50%. And it is extremely important for 2 reasons.

  1. Recent research shows that the climate accounts in relation to the use of biomass are far more complex than first assumed. More and more problems are being seen in connection with an increasing need for biomass at an international level. The notion that biomass is CO2 neutral in line with the wind and solar is in sharp decline.
  2. There has recently been an increasing number of political announcements that biomass is a transitional solution. Therefore, it can not be expected that the use of biomass will remain tax-free in the future. In the end, it will be the consumer who will pay any. rising taxes.

The need to reduce both the use and the need for biomass in energy production can therefore not be emphasized enough if one wants to secure the future of the energy sector.

“With the new photovoltaic systems from Solar Nordic, we ensure that we can produce the heat efficiently and at the same time utilize the varying prices on the electricity market to buy and sell electricity, respectively, when it is most advantageous. The choice of Solar Nordic is based on best quality, knowledge, and price and because they had several good inputs to optimize the solar park ”.

“It is simply the best and most advanced I have seen. If you can live out the potential that has been set up, then it will be a place people come to see. ”

Data for the solarpark

The size of the solar park is 5.4 MW.

The annual production will be 4,560,000 kWh, which corresponds to the electricity consumption of 1,100 households.

The mounting system is self-developed, designed, and produced in Europe for Solar Nordic.

The inverter is from Huawei.

The transformer is from ABB.

Solar Nordic is responsible for everything from the first idea and design to the finished connected solar park.

Special for this park are:

  • The panels face east/west and not as usual to the south. South-facing plants provide the overall highest production but with high peak production.
  • East/west facing panels, on the other hand, give a flatter production curve from early morning to late evening.
  • 30% greater capacity in the same area.
  • The park is east/west designed so instead of 0.8 MW / ha, the effect is up to 1.1 MW / ha. Electricity production has increased net by 22% compared to a normal south-facing solar park.
  • 100% European Modules
  • 95% of all solar parks use Chinese modules, but Assens has chosen the Spanish manufacturer Eurener, which provides a 20-year guarantee against the usual 10-12 years.

The solar park creates new economic opportunities

The primary function of the solar park is to supply power to a heat pump. This is expected to produce 40-50% of the total heat demand. That is because the COP value of heat production is almost 4. The value of the electricity produced in the solar park is also worth 4 times more. This gives Assens Fjernvarme some unique opportunities to act both environmentally and financially appropriately:

With increasing demand and high prices in the electricity market, the electricity produced from the solar park can be advantageously resold. furthermore, the heat pump can also be powered by biomass.

When the electricity price is low. The heat pump can be operated using the solar park, which is designed to halve the consumption of biomass on an annual basis.

This means not only increased competitiveness as a result of a cheaper consumer price. Although it has a much greater flexibility as well as increased access to the electricity market’s system regulation.
