Solarday is a historical Italian module manufacturer, specialized in high-end products and customized PV Solution, located in Lombardy. In 2018, the international expansion towards European markets began. Their Italian factory plus their variety on EU suppliers, allow them to have a pure European module, on minimum production time, and being flexible on demand. As well as the PV market, Solarday keeps its growing plan and expansion for 2021 opening a new subsidiary in Spain, covering the Spanish and Portuguese markets. Solarday was recently awarded with the Top Brand PV Modules Italy 2021 Seal from EUPD Research, a leading certification body in the PV industry.

Easy Engineering: What are the main areas of activity of the company?

SOLARDAY: Solarday’s production know-how stands for many years of experience, new impulses and innovative new developments. Our core business is to produce PV modules, as well as integrated PV solution, such as All in one solution, on PV Roofs, as well as colored solar roof tiles. PV is progressively entering within the alphabet of contemporary architecture and architects, similarly to any other building material.

E.E: What’s the news for 2021 about new products?

SOLARDAY: We are making the same evolution as the market, adapting our machinery to new cells, and half cut modules. For a long time, photovoltaic systems are not always considered aesthetically enhancing to a building. But if BiPV is properly considered since the early design phase, the architectural design can become the way for ensure a better integration of PV from the aesthetic, constructive, energetic and economic perspective.

E.E: What are the ranges of products?

SOLARDAY: From old modules, still using 5 inch cell, to M12, also finding solutions on BIPV and integrating modules on historical and monumental cities or neighborhoods, please check the interview with the Italian architect Lorenzo Drago (ACME Milano): 

E.E: At what stage is the market where you are currently active?

SOLARDAY: Strong position in Italy, expanding to EU, and as strategy opening facilities in Spain. Solarday announces the opening of a new office in Valencia, Spain, with the aim of continuing to ensure presence and support in Europe.

The opening of a new office in Spain is a major step in the internationalization process undertaken by Solarday.

E.E: What can you tell us about market trends?

SOLARDAY: It is already on the market the cells cut in one third (1/3), this is going to become the following trend, and mass production will follow. However, modules can get more efficient, but no sense in getting bigger and bigger as they need to be handled by 2 installers. Solar modules and its production are becoming a mature product market, where from now on, we will see differentiation strategies from PV manufacturers.

E.E: What are the most innovative products marketed?

SOLARDAY: This year we started to produce smart modules, by assembling our modules with microinverters and optimizers too. A microinverter will take full advantage of the production of each individual panel. It will convert the power generated by each panel to the grid voltage. Each solar panel and microinverter combination can “do their best” and contribute as much power as they can.

Solarday group controls the development of technologies at all levels in-house.

E.E: What estimations do you have for 2021?

SOLARDAY: We have increased our revenue by 30% compared to last year, We could reach that position thanks to the investments carried out in this sector and, as well, thanks to the favorable economic conditions of the last year.

After a consolidation phase following the first full feed-in tariff based European solar boom, the Continent’s largest economy’s solar sector has been experiencing a second boost as of 2018. This is due to a combination of self-consumption with attractive feed-in premiums for medium-to large-scale commercial systems ranging from 40 kW to 750 kW.
