Power-to-gas and other chemicals-based storages are often suggested for energy systems
with high shares of variable renewable energy. Here we study the North European power …

The profitability of a rooftop solar photovoltaic (PV) system depends on several factors, such
as the retail price of electricity, the load profile of the building, and orientation of the solar PV …

The amount of installed solar power in Finland is increasing as a result of decreasing
photovoltaic (PV) system component prices. The growth is especially noticeable in …

There are several barriers to achieving an energy system based entirely on renewable
energy (RE) in Finland, not the least of which is doubt that high capacities of solar …

Domestic hot water (DHW) heating is one of the most energy-consuming activities in a
typical household. Photovoltaics (PV) connected with a ground source heat pump (GSHP) …

Electrofuels, including hydrogen, methane and ammonia, have been suggested as one
pathway in achieving net-zero greenhouse gas energy systems. They can play a role in …

Large number of photovoltaic (PV) installations can lead to the network constraints'
violations that comprise the voltage level outside the statutory limits and equipment ampacity …

The increasing use of solar photovoltaic (PV) systems supports the growth of renewable
energy sources but introduces challenges to distribution networks, such as voltage rise …

Aurinkosähköjärjestelmät ovat lisääntyneet Suomessa huomattavasti viime vuosina.
Asennusten nopean lisääntymisen vuoksi myös aurinkosähköjärjestelmien asennuksessa …

The object of the study was to create a model for estimating energy efficiency improvement
investments and for comparing profitability of the investments. The technologies studied are …
