Solarium, a Japanese brand of solar panels, has won the title of best-selling solar panel in Germany.

The company, which also sells its own solar panel, has sold more than 1.2 million panels in Germany, including about 4.5 million in the past three months.

Solarium’s sales increased 2.5 percent in April, but were flat in May, the company said.

It said sales in the second quarter fell 8.5 percentage points compared with the first quarter, partly due to a slowdown in the European solar energy market.

Solaris has a strong brand in Germany and has recently attracted more orders.

Solarism, the name of Solarium solar panels and other products, is a subsidiary of Solaris.

“We are very happy about this result, as it represents a positive development for our business and we are very grateful to our customers for their support,” Solaris said in a statement.

“It also shows the power of our products and services, which is why we have been very successful in the global market.

This results will allow us to develop further.”

Solarium will sell its solar panels in two European markets: Germany and France.

Solarist, the German-based company that makes Solarium panels, also sold 1.4 million solar panels.

Solarity, another German-listed company that sells solar panels under Solarium names, said in March that sales in its European market dropped 13.4 percent.

Solarizing solar panels are sold by companies such as Solaris, Solaris’ own subsidiary, and other solar companies.

Solarists sales fell 3.1 percent in May compared with May 2015, mainly due to the slow market.

In France, Solarism said it sold more solar panels than it had in the previous quarter, mainly because of the introduction of new products in the country.

The new products included the first solar cell that has a capacity of 1 kilowatt-hour (kWh) and the solar panel with a capacity ranging from 6.5 to 12.4 kilowatts (kW).

Solarism will sell solar panels at its retail stores in Germany in 2019.

The Solarism company is a division of Solaria, which merged with Solaris in 2013.

Solaria also sells solar-powered solar lanterns.

Solari, the Danish company that owns Solarium products, also reported strong results.

Sales in Denmark fell 6.4-percent in May from the previous month.

Solarius, the Chinese-listed Chinese company that operates Solarism solar panels with its own brand, said it had been able to attract more orders than expected because of strong demand for solar-based lighting products.

The group also said that solar lighting sales rose 2.2 percent in the first three months of the year compared with a year earlier.

In Europe, Solaria and Solarism sold about 1.3 million solar products in April and May, while Solaris sold nearly 1.5 and 1.6 million, respectively.

Solarice, which owns Solaris products, reported sales of more than 6.7 million solar-panel products in March, up from about 5 million a year ago.

Solaric, a German-owned company that is a competitor to Solaris and Solaris brands, reported that it sold 2.1 million solar lantern products in May.

The European Solar Industry Association, which represents solar panels manufacturers, said that the sales figures were driven by a surge in demand for PV lanterns from consumers.

“This was partially driven by increased demand for large-capacity solar power plants,” the group said in its annual report.

Solariac, which had a market value of about 4 billion euros ($4.2 billion), reported that sales rose 8.1-percent year-on-year.

Solarite, a Danish company, reported strong sales of nearly 8 million solar lamps in May and June.

The German solar industry group, Solariges, said its sales rose 6.3 percent in March.

Solarion, a subsidiary that sells Solarium lanterns, reported a 3.6-percent increase in sales in May in the same period.

Solarigess, a division that sells other solar products, has about 3.2-million solar products sold in the market.
