What clients say about us


Yes! The Milk the Sun PV Returns Planner was developed to make various investment opportunities in PV systems easily comparable and to present such investments in a clear and understandable manner.
For this purpose, all evaluation criteria relevant for decision-making are shown transparently and clearly both in graphic and tabular forms. The Planner in this form can also be used to present a PV system in terms of yield and returns to investors not specializing in PV sector.
No, the Planner shows the cost structure, as well as the yield and returns situation, and can be used as the basis for deciding whether you need to optimize the yield, cost or funding factors.
However, the Planner does not provide any recommendation for action. If you want to have an expert opinion based on the PV Returns Planner, please contact us!
For your investment several comparative values are shown regarding your cost structure. For example, you can see how your insurance costs or the purchase price of the PV system compare to current market prices. To enable such a comparison we use market prices and standard assumptions.
There are many ways to optimize PV systems in order to influence the costs and yields of the system. The yields can be increased, for example, by means of cleaning, repowering or nanocoating. The costs can be optimized, for instance, through re-financing, changing insurance or adjusing the maintenance contract. The PV Returns Planner can serve as a decision-making tool, as the yield and returns structure are clearly and transparently presented.
Milk the Sun's Returns Planner includes all major factors that can help you to decide for or against investing in a particular PV system.
The planner estimates such factors as, inter alia: Fair Value, return on equity and return on investment, amortization, yields, cash flow (without taxes and depreciations) and sensitivities.
In the photovoltaic market investors have clear return expectations, which are used as the standard for determining the current value. It means that the current value can be determined on the basis of the given life cycle and fixed return. This gives you a benchmark that can be used for fair valuation by both buyers and sellers.
To simplify the input and to avoid implausible values, we make some basic assumptions for determining the PV return, such as a returns expectation of 6% and a remuneration period of 20 years. Each assumption is clearly marked as such in the Planner. One of these basic assumptions is the disregard of taxes and depreciation. A pure analysis of earnings before tax is carried out for you.
No. You can purchase the Planner only if you have a free Milk the Sun account. You can then easily download your planner from your personal free of charge Solarganizer.
The purchase price is a relevant factor for determining the returns of the photovoltaic system. When evaluating a system in operation, however, the purchase price may not be included in the analysis of the returns. Here only the future returns are important, and, for instance, an excessively high price already paid for the PV-System has no influence on future returns. However, even in this case you need to specify the purchase price, as this is an important variable for many background calculations. For example, the equity ratio is calculated on the basis of this input.
No. The Planner does not cover depreciation. The effects of an expense or, for example, special depreciation for PV-Systems on the individual tax burden are also not covered in the report.
Generally it is a pure pre tax consideration.
The Fair Value shown in the report provides both the investor and the seller or the operator of a PV-System with an indication for the valuation of the system in question based on the usual return expectation of an investor wishing to purchase a PV-System.
However, it must always be kept in mind that the actual price at which a photovoltaic system is sold or purchased depends on many factors that the PV Returns Planner can not reflect: actual technical condition of the system, evaluation of the components and of the design, personal preferences of an investor, negotiating skills of actors, seasonal effects and much more.
The following assumptions can be changed: the calculation date, the discount rate of 6%, the inflation rate of 0% and the start of the second loan which begins with the first loans.
