What should I watch out for with solar power?

Solar power , this is the environmentally friendly and, thanks to targeted state subsidies, highly worthwhile alternative for homeowners to use their home as an investment form. The state here guarantees a maximum feed-in tariff for photovoltaic systems, so that, if the property is structurally suitable, energy costs are reduced and, additionally, the excess levy generates a financial benefit.

This article is intended to give you some indication, as well as reference A checklist makes it clear what matters here. After all, in any case, the first investment, then the years of leasing the roof area including the plant and then the increase in value that your property ultimately learns thanks to the sustainable technology.

The 10-point plan

1. Suitability of the roof

Fueled by the application of various providers, that a large part of the German real estate for the installation of photovoltaic systems is suitable, a detailed analysis is recommended. Roofs with a minimum slope of 30 degrees and south orientation are considered to be ideal for use. Orientations to the west or east may also be appropriate, but reduce the potential utility. According to widespread opinion, with appropriate techniques and installations, an efficiency of up to 90 percent can still be expected here. Incidentally, the south of Germany naturally provides better conditions than the north, since the annual hours of sunshine differ dramatically, so that it is important to pay attention to the basis on which the profit plan of your plant is calculated.

2. Diversification of the exporting supplier

Chinese plants, which, in particular, have lowered prices and increased competition, make it difficult to choose the appropriate supplier. It is therefore always recommendable to invite several consultants, so that you can compare. Especially with the investment costs as well as the calculated yield, but also with the contractual arrangements and the cost structure of the leases, there is a wide range of things to consider. Here it is advisable to ask in the neighborhood which provider has been chosen and what experiences have been made to possibly obtain preferences.

3. Knowing and considering value for money

The assessment of whether an offer is cheap or rather expensive is based on several points. In popular Internet forums, users and interested parties discuss technologies, providers and co., So that you can also post offers that users then objectively evaluate and assess based on their experience. Basically, it is so important here that the costs for a plant may be as high as the amount that is obtained through the feed-in tariff within 10 years. Currently, the price range per kWp installed (kilowatts / peak = maximum capacity) ranges from € 1,500 to € 2,500, depending on regional circumstances and the technology used and the efficiency class.

4. No approval requirement on the part of the building authority

Despite the current legal situation that no approval must be obtained for such installations on the roof, it is advisable to inquire with the responsible building authority. The clerks look more closely at listed buildings in particular, so that it can definitely lead to a negative assessment. In this sense, it is therefore advisable to make a written request in advance of a specific construction project in order to enjoy legal certainty.

5. Check funding opportunities

Banks providing loans in the field of solar energy generally require a minimum of & frac14; Equity. Here, you should particularly note the funding programs of the Kreditanstalt für Wiederaufbau (KfW Banking Group), which may imply additional reductions, especially in the current low-interest-rate phase. Their advantage here is that the Renewable Energy Law & ldquo; (EEG) provides for a feed - in tariff that relates to every kilowatt of solar power and is designed for a period of up to 20 years.

6. Calculating Profitability

An important factor in harnessing solar energy is that, in addition to the low cost of own electricity, you can get compensation that makes your investment profitable. Special calculators that you find on the Internet give you values ​​based on specific parameters and specifications, so you can calculate them for 15 or 20 years. Pay particular attention to tax peculiarities and the duration of the legally guaranteed maximum feed-in tariff by comparing your income with investment costs and debit interest .

7. Note Structural Events

For a profitable investment in photovoltaic systems, it is usually necessary to use a period of 20 years or more as a benchmark. Here it depends on the condition of the roof regularly, because by repairs could result in costs, which reduce the yield. Depending on the age and quality of the building fabric , it depends on whether you can use existing channels for necessary lines or not. To calculate the feed-in tariff, it is therefore necessary to install a second meter. If you additionally intend to use the produced energy separately, you will need another counter.

8. Check insurance

Although there are no significant risks associated with the installation and operation of photovoltaic systems, it may be useful to prepare for any damage. Due to your position as a taxable entrepreneur, you may need a so-called business liability insurance , which regulates damage due to severe weather on the facade, the plant itself or to third parties. Depending on the contractual situation, the photovoltaic system itself is covered by homeowners insurance. Pay particular attention to the sum insured, provided that your policy also explicitly applies to solar cells and Co. Depending on the size of the system, there are also so-called default insurance policies that replace lost revenues with feed-in, provided the system is damaged or otherwise impeded.

9. Check supplier's feed-in tariff

The named Act obliges network operators to pay fixed remuneration for solar power purchased. Often, these are above the prices charged by home users as they have been politically motivated to create an incentive for a contemporary energy supply . For this reason, you as a solar power generator conclude a feed-in contract with the network provider, which is not subject to any legal provisions. In particular, pay attention to rent costs for feed-in electricity meters and the distribution of liability assumptions, which have a big effect on the profitability of your system. Therefore, have them checked in advance and you should heed the above advice to compare several offers intensively.

10. Pay attention to VAT refund

The tax office then knocks on your door when the installation is complete and the operation of your system begins. In addition to the feed-in tariff, the network operators will refund you the Value Added Tax , which you must also pay to the tax office. Create a special folder because profits and losses within the eligibility period are tax-relevant and tax offices are happy to carry out examinations. This refers regularly to the contract structure and ownership of land and property, which is particularly relevant for large users such as farmers and the like.

Concluding remarks

Whatever your contract is designed, there are plenty of differences and thus the utilization of the system with the chosen supplier stands or falls. So use your friends 'and neighbors' experience, ask critical questions, and stay up to date on technical changes so that you can objectively assess the revenue opportunities with third parties.

As with real estate financing itself This is about long-term , and at the same time expensive investments that sometimes take years to yield. Too short to take revenge here quickly, because adjustments are associated with additional costs , which are at the expense of your earnings.
