Renewables
The sectors in which we operate
Over the years, we have specialised in various areas in addition to photovoltaics. This is to give you an all-round service in the field of renewable energy, for your home and your business. Find out how we can help you and do not hesitate to contact us.
Corporate/Residential Photovoltaics
The photovoltaic sector in Italy has reached maturity thanks to the 18 GW already installed. Thanks to the strong know-how acquired through the installation of more than 500 systems of all sizes (from 3 kWp to 9.7 MWp) for a total of more than 100 MWp, and also through Regran-lab (a company laboratory where the best performing products on the market and different technologies have been tested since 2007) Regran is now able to offer turnkey construction and after-sales services at extremely competitive prices, proposing the most advantageous solution for the end customer.

Concentrating solar power
Concentrating solar technology involves the use of mirrors (reflection) or lenses (transmission) that concentrate the radiation incident on a large surface into a smaller one occupied by the photovoltaic cells, increasing the intensity of the radiation incident on the modules. It works mainly with direct radiation. This technology requires the use of an automatic tracking system on one or two axes, which aims to maximise the energy and economic efficiency of the photovoltaic modules installed on the system; CPV modules, thanks to the special optics of the glass, are able to further increase the efficiency of the system. Regran installed a 1 MWp concentrating solar power plant in 2012 and has therefore developed a strong know-how on this technology.
Solar thermal
Thermo-dynamic solar
The function of the thermodynamic solar system is to concentrate solar energy on a receiver system to heat a heat transfer fluid to high temperatures. The hot fluid is stored in reservoirs, allowing the collected thermal energy to be accumulated. Water, or alternatively molten salts, silicone or diathermic oils can be used as the heat transfer fluid. The thermal energy will then be transferred from the carrier to a special system which will convert it into electrical energy by means of an oil-free Organic Rankine cycle.
Mini-Wind
Biomass
Cogeneration
A thermoelectric plant that produces electricity using high-temperature heat as its primary source necessarily also produces heat at a lower temperature, which is generally released into the environment. When it is possible to recover part of this heat, which is used by a thermal consumer, a cogeneration system is created, which improves the thermodynamic efficiency of the system. Through such a system, primary fuel energy savings are achieved compared to the separate production of the same quantities of electricity and heat. Such cogeneration systems vary in size from a few kWe up to a few hundred MWe and come in the form of various technologies, the most common of which are:
- Internal combustion engines
- Gas turbines and microturbines
- Steam turbines
