More and more companies are turning to renewable energies and converting their operations, because energy consumption represents a significant cost factor in the company. Our team at MaxSolar will advise you individually and personally on the subject of photovoltaics in the commercial sector.
The energy production costs for the conversion of solar energy into electricity or heat continue to fall, thanks to optimised efficiencies and so-called economies of scale through mass production. Despite declining EEG remuneration, the first large PV plants are showing that they can generate green electricity economically and cost-effectively in Germany even without government subsidies.
We are pioneers in the market testing of subsidy-free plants in which the electricity produced is marketed by means of a long-term power purchase agreement (PPA) – Reference PPA [news: Link to Burhafe ground-mounted site]. For the year 2040, electricity production costs of 2 to 7 cents per kilowatt hour, i.e. below the costs for electricity from wind and fossil gas, can be assumed (source: Fraunhofer Institute ISE). The so-called peaks or load peaks for industrial and commercial electricity consumers are not only particularly relevant for grid stability, but also for electricity costs. A holistic storage system regulates these load peaks by means of peak shaving. The installation of charging infrastructure for the company's electric cars not only exploits all the possibilities of photovoltaics in the commercial sector, but also promotes the company's sustainable image.
In the case of special project requirements, personal contact persons weigh up commercial aspects, planning and contractual risks within the framework of a feasibility study thus providing a basis for decision-making through the feasibility and economic viability of the planned project on photovoltaics in the commercial sector. A reliable yield forecast is essential as early as the planning stage in order to be able to correctly dimension and technically equip the system. What matters here is a thoroughly thought-out concept.
At the beginning of our cooperation, we work with you to determine the local conditions and project-specific features of the PV project being planned in order to create the ideal conditions for an individual conceptual design. With the help of professional software, an initial layout plan including a yield forecast is then drawn up. Numerous factors for photovoltaics in the commercial sector are taken into account. In addition to the annual cycle of solar radiation based on climate and weather data from the DWD [German meteorological service], the annual yield of a PV power plant is influenced by the roof pitch and shading, the geographical location, construction type and installation angle of the modules, as well as the technical properties of the individual components such as the inverters and modules installed.
We not only advise on the yield-optimised size of the PV system, but also present you with the resultant refinancing in accordance with the current legal framework conditions, for photovoltaics in the commercial sector for example. Against this background, we will provide you with an individual solution with the optimised yield for your roof or open space. If desired, together with a corresponding solution for storage systems and charging infrastructure for electric vehicles.
In recent years, the acquisition costs for photovoltaic systems have fallen continuously. This also made it possible to significantly reduce the electricity production costs. More and more plants are being without subsides. The costs are influenced by the system size / number of modules and module type, the required transformer stations, the necessary route length and the number of inverters installed. In addition, there are the expenses for technical management (TBF). When calculating quotations for commercial photovoltaics, for example, we always focus on the economic efficiency of your system. The results from the profitability calculations of our professional software are incorporated in this.
PVSyst is the only yield calculation tool for commercial photovoltaics in Germany that is recognised by banks. Compared to other calculation programs, PVSyst considers the entire planned PV park. From the irradiation at module level to the transfer point to the grid.
This includes loss values in the transformer area as well as cable losses in the route planning and the transfer protection station. Operationally, these loss values are presented via a standardised input, which is repeatedly checked at irregular intervals against real system losses.
The result is a detailed report of the calculation of the specific annual yield and a loss diagram indicating where what power is lost in the planning of commercial photovoltaics. A 3D near-shading scenario takes into account all close-up shading objects in the vicinity (e.g. transformer stations, power poles, trees).
Power Purchase Agreements (PPAs for short) are private-sector supply and purchase contracts and an important component of energy transition. Once grid parity has been achieved, there will be further opportunities for ground-mounted photovoltaic systems outside the legally prescribed areas (e.g. along railway lines, motorways and conversion areas) in addition to the classic financial support via the renewable energy sources act.
MaxSolar is considered one of the industry leaders in the development, contract negotiation, financing, construction and operation of PPA plants. We offer our full service exclusively for projects such as photovoltaics in the commercial sector, which we accompany as project developers for our customers.
