Solar Power Plants
Private consumption is coming more and more frequently to the forefront here through the feed-in tariff becoming even lower due to the EEG (German Renewable Energy Act).
Production costs of solar generated energy is around 9 cents/kWh for small solar power plants in the meantime – and this is to last.
Most energy providers and resellers offer power at a price of at least 22 cents or more per kWh.
This means a saving of at least 13 cents a kWh for plant operators.
According to statistics from the German Federal Environmental Council and from the Fraunhofer Institute, around 25-30% of power produced is used by the plant operator in the private sector in a solar power plant adjusted to one’s needs.
This electricity must not thus be purchased at higher costs from an energy supplier.
This lowers costs and makes you at least partially independent from the constantly rising energy prices.
With suitable energy storages dimensioned economically and sensibly and designed with durability in mind, this rate can rise to approx. 80-90%.
This is almost complete independence which was achieved just with a one-off investment.
Electricity which is generated during a holiday or other explained absence and thus not used by the operator is automatically fed in and even compensated for. Through this, solar power plants also pay off when no one is at home.
Just think about the “aftermath” if your feed-in tariff agreement with your energy supplier comes to an end:
In the last 15 years, energy prices have more than doubled from approx. 19 pfennig [German penny prior to the introduction of the Euro] to an average of 23 cents.
What do you think the price per kWh will be in 20 years?
The German Federal Environment Council estimates the average price of electricity to be 50-60 cents per kWh in 20 years.
You will however continue to produce your electricity for only 9 cents/kWh.
It is in any case understandable that energy suppliers are against the further increased construction of solar power plants, as you, as a solar power plant operator, are a customer who will be lost to them forever!
Well, if that is not a wise investment for the future, I don’t know what is!
Industry has always been a pioneer of innovations and the newest developments.
Industry also recognised early on that production and operation costs can be stabilised through self energy generation using solar power, cogeneration units and even small wind energy plants.
Through one-off investments and solar power plants suited to your needs, electricity can be generated at a calculatory fixed price – a significant and important factor in cost calculation of the respective products.
In winter months, if the electricity yield by the solar power plant is not enough, cogeneration units make a considerable contribution to the generation of power as well as heat.
This is an optimum energy mix, which results in near independence from energy price hikes.
Cities, communities and local companies have increased their contribution to the turnaround in energy policy this year.
The feed-in tariff, which is criticised by many lobbyists, and which supposedly sends the price of electricity soaring for the end user in their opinion, completely takes a backseat here as it occurs less and less often.
The aim of local and public authorities is to offer a low-cost energy production through an ecologically healthy mix of energy.
The generation of electricity through solar power on otherwise unusable surfaces is likewise an important building block, like generation of heat by means of cogeneration plants which generate electricity at the same time as heat.
Large wind power plants continue to meet public resistance.
Because of this, many cities and communities think about using small wind power plants, the technical progress of which has been very widely developed in recent years.
Agricultural companies have been using solar power to generate energy for years.
Large roof surfaces on existing barns and tool sheds which are already available are put to ecologically friendly use through the assignment of solar power modules.
Due to the feed-in tariff which was still quite high a few years ago , investments amortised relatively quickly.
In the pig fattening sector especially there is a very high need for heat which is increasingly produced through cogeneration units.
These cogeneration units produce the required heat in those times whilst electricity is produced at the same time for free, especially in solar-poor phases.
This can be used in your own agricultural business.
The principle ‘Energy must be generated where it is used’ also applies here.
Free-standing systems were in the past principally erected by investors or investment companies as profit orientated financial investments.
However, these financial investments are increasingly losing appeal for this target group due to the starker and starker reduced feed-in tariff.
The strong expansion of the construction of free-standing systems at home and abroad contributed, for a significant part, to the cost of modules – and with them the cost of power plants – reducing very strongly in price however.
In times of tight purse strings, local authorities, communities and individual public utility companies recognise that solar power plants can be lucratively operated at current prices, even if the feed-in tariff is relatively low.
With a mix of renewable energy sources, such as solar power, cogeneration units and wind power plants energy, costs can be calculated in the long-term and be factored into the yearly budget.
Renewable energy sources thus create a sustainable contribution to independence from rising energy prices which can be further built upon with advancements in technology, for example storage media.
