Organise your contracts and documents most efficiently with the Solarganizer powered by Milk the Sun

Running a PV system has many advantages. You potentially save a lot of money when self-consuming your solar power – plus, you can even earn money by selling the green energy you generate. However, owning a solar plant involves quite a bit of bureaucracy, too.

Over time you will accumulate a large amount of documents: from construction and leasing papers, to maintenance, insurance, financing, optimisation contracts, additional warranties, yield reports, bills, bookkeeping and tax documents. With all this paper work, it may easily happen that you forget maintenance and cancellation periods. Or you end up overpaying for existing contracts or even lose important receipts.

What you should not forget is that as a PV system owner you automatically become an entrepreneur. This means you are obliged to preserve all records regarding your solar plant and organise a thorough bookkeeping of your PV documents.

The Solarganizer powered by Milk the Sun provides the best solution for PV system owners. It is a digital organiser that allows you to manage and organise all contracts and documents according to a standardised pattern – completely free of charge. It also professionally evaluates your existing contracts. Its automatic reminders alert you in advance of an important date such as cancellation periods, warranty and insurance periods as well as remind you of deadlines for tax and bookkeeping issues.

Your documents will be permanently and safely stored via SSL-encryption on German servers.
