What is meant by the cost of solar energy?
The cost of solar energy is determined by the size of the solar power system, the number of hours of power produced, and the number of incentives and discounts given by the government. Larger solar-powered systems will generally cost more to install and consume more electricity. There are various rebate and incentive programs that can help offset system installation and power conversion costs.
The most expensive cost of solar energy is the installation and maintenance of solar panels. A solar power system captures sunlight captured from the panels and covers it with electricity, which is routed through an electrical panel and into the building’s existing electrical wiring. The meters keep track of the building’s electricity consumption and its share of solar energy. In the United States, electricity use is typically measured in kilowatt-hours.
Electric companies generally have a predetermined rate per kilowatt-hour that they charge their customers. Additional charges and surcharges may be included in the total bill; However, the amount of kilowatt-hours used is the primary way to calculate the cost. The cost of solar power is largely determined by the use of kilowatt-hours. Meters are read to determine the amount of energy used in a given period of time.

There may be special rates for the kilowatt-hours generated by the use of solar energy. Some jurisdictions and local governments offer generation incentives to reduce solar energy costs. With these incentives, a building owner’s installation of a solar power system is more cost-effective, as the kilowatt rate is often significantly lower than that of standard electricity. Unlike standard tariffs, the tariff applied to solar energy can remain relatively stable.
Discounts are generally available for building owners who wish to install solar energy systems. It is an additional saving tool that can help offset the cost of solar power. Since these systems require a large outlay of money, the rebate puts those funds back into the hands of the owner. The overall installation cost is reduced and homeowners can enjoy the long-term benefits of avoiding utility rate increases.
One of the main cost factors is the size or quantity of solar panels required to meet the building’s electrical needs. Usually, a large building requires a larger system than a small structure. Some building owners choose to convert only a portion of their electricity needs from solar energy and can afford to install a smaller system.

Determination of Photovoltaic Costs and its Advantages
Obtain free energy from the sun and be independent of the major electricity providers: this wish can be fulfilled with a photovoltaic system. But before the electricity comes from your own roof, you need to invest in the necessary technology.
Are the system and installation paid for with your own money or is the financing necessary? What funding opportunities are there and what returns can you expect as the operator of the PV system? These and other questions need to be answered.
If, on the other hand, you would like to know exactly what your personal PV project will cost, you can obtain a free, non-binding offer here.
What costs have to be taken into account when building a photovoltaic system?
Like any investment, the cost of solar energy is calculated by buying a PV system is only worthwhile if it recovers its costs within a reasonable period of time. The current price for electricity is around 30 cents / kWh. According to a study by the Fraunhofer Institute for Solar Energy Systems, the production costs (costs for generation) of a kWh of solar power for small systems under 30 kW are between 5.81 and 8.04 cents in southern Germany and between 7.96 and 11.01 cents sunnier north (as of 2021). The electricity production costs for small-scale PV systems with battery storage are between 8.33 and 19.72 cents / kWh and are therefore still well below the costs for grid electricity.
The investment cost of solar energy for economical small-scale PV systems with 5 to 15 kWp should be estimated at 1,000 to 1,800 euros per kWp . A 10 kWp system costs around 15,000 euros, a price that can be reduced through subsidies and tax optimization. Thanks to the savings in electricity costs, the investment will pay for itself within about 10 years. The lifespan of a photovoltaic system is at least 20 years, Solarwatt gives a 30-year guarantee on the durability and performance of all glass-glass modules.

kWp – what does that mean?
KWp or kilowatt peak describes the electrical power output by solar modules under standardized test conditions (STC). The unit is used to compare different solar cells under standardized test conditions.
kWh – what does it mean?
kWh or kilowatt-hour is a unit of electrical energy. A kilowatt-hour corresponds to the energy that a device with an output of one kilowatt (1,000 watts) consumes (or generates) in one hour.
When looking at the costs, it quickly becomes clear that the age of fossil energy generation is inevitably drawing to a close. Not least from a cost-benefit analysis, regenerative energy sources are becoming increasingly important – not to mention the positive effects on the environment and climate.
All areas of our life are affected:
- Private households
- public sector
The energetic change – away from fossil fuels towards renewable energies – is accelerating. Photovoltaics and solar systems already offer the possibility of significantly reducing CO 2 emissions when generating energy.
Modern photovoltaic systems – also referred to as PV systems, solar generators or solar power systems, are often an attractive option in our part of the world, with which houses, commercial properties as well as industrial plants or public areas can be supplied with regenerative energy. The advantages of this technology are obvious: In terms of their performance, solar and photovoltaic systems are very affordable. The technology is mature and has long since outgrown its niche existence.
