Checkwatt reaches 3000 installations

Within just 9 month Checkwatt has increased the number of solar installations they manage from 2000 to 3000 customers. This significant increase underlines Checkwatts leading role as provider for complete solutions to monitor energy production and energy consumption.

The CNet spin-off company Checkwatt offers solutions and services for measuring and visualising electricity production from solar energy and enables homeowners to trade energy certificates.

Checkwatt is proud to announce 3000 finished system installations based on the IoT gateway developed by CNet.

Checkwatt reaches 2200 installations

With spring approaching the weather is more suitable to install solar power systems. Within the brief period of spring, Checkwatt has already gained over 200 new customers and the CNet spin-off company proudly announced breaking the mark of 2200 finished system installations.

With the currently installed number of systems Checkwatts maximum capacity of electricity as reached 48.361 kW/h. A significant share of Swedens solar energy production.

Checkwatt expands

CNets spin-off company Checkwatt offers solutions and services for resource efficiency through information, measurements, and visualization. CheckWatt AB offers products and IT services within the fields of renewable energy and energy efficiency for both private and corporate customers.
With a fast-growing customer base in Sweden Checkwatt aims now to extend its customer base to other countries within Europe and extend its services to the demands of changing electricity systems and markets. The growing number of consumers installing solar panels and contributing to the electricity production create the opportunity to reduce CO2 emissions to mitigate climate change but also have new demands on the grid. Structures need to decentralize to meet the requirements of the changing market. In most European countries the grids consist of central gigawatt-scale generating units, thousands of miles of high voltage transmission lines, minimal energy storage and carbon-based fossil fuels or nuclear energy as a primary energy source. The possibility to deploy growing numbers of intermittent renewable generating sources offers the possibility to decentralise the market and create so-called microgrids as a flexible architecture for deploying distributed energy resources.

Checkwatt reaches 2000 installations

With prices of solar installations reducing, production efficiency increasing and more and more aesthetically options to choose solar panels are on the rise in Sweden. The number of homeowners and companies which equip suitable surface areas with photovoltaic systems is steadily growing.

More and more homeowners decide to invest in a solar installation. Sweden has sufficient sun exposure to generate renewable energy with solar installations. Investment costs of a solar installation are usually retrieved by state subsidiaries, savings in energy costs and selling surplus electricity within less than 15 years. Considering that manufacturers offer usually a 25-year performance guarantee on solar panels, installed systems provide free electricity after writing off the investment. Our spin-off company Checkwatt offers solutions and services for measuring and visualising electricity production from solar energy, and trading with energy certificates.

Checkwatt is proud to announce to register the 2000th customer this month.

With Sweden as a fast growing and dynamic market for photovoltaic installations, the numbers of PV installation and the production capacity steadily increases. Checkwatt as leading provider in Sweden for complete solutions in energy production and energy consumption for both private and corporate customers continues to increase its customer base and market share.

By combining electricity meters, electricity certificate meters and user-friendly visualization, our spin-off company Checkwatt helps its customers to keep track of the entire energy production chain and supports the certification of energy produced and fed into the grid.

Checkwatt achieves 1.600 installations

Since 2007 the number and capacity of Photo Voltaic installations in Sweden has significantly increased. Declining prices of photovoltaic equipment, as well as the introduction of the direct capital subsidy system in 2006 and a revision in 2009, make photovoltaic installations competitive. The number of roof-mounted systems installed by private persons or companies built on self-consumption business models has steadily increased and reached a new record in 2017.

Checkwatt, which is a spin-off company from CNet, provides complete solutions in energy production and energy consumption for both private and corporate customers has also significantly increased its market share. By combining electricity meters, electricity certificate meters and user-friendly visualization, Checkwatt helps its customers to keep track of the entire energy production chain and supports the certification of energy produced and fed into the grid.

Checkwatt is proud to announce to have reached 1.600 finished system installations today.

CNet one of finalists in Fortum AI Hackathon

There are four global megatrends that shape the energy sector: climate change and resource efficiency; urbanisation; new technologies and digitalisation; and active customers. These megatrends will bring profound changes not only to how energy is produced and sold to customers, but also to how it is consumed in our daily lives. Fortum is now looking for novel AI-assisted services for customers’ homes and have organised a hackathon challenge AI Comes Home. CNet has been selected as one of the finalists for this hackathon that will take place 7-8 December. We will participate with a intelligent digital assistant that combines both video and voice input to guide consumers in living a more sustainable life.

CNet delivers Energy Efficiency solution in Amazonas


The IMPRESS project had its final review in April. It took place in Brazil. The use case has been the famous opera house Teatro Amazonas in Manuas in Brazil. In the project CNet has developed deployment tools for installations of large scale IoT applications. Also a set of development tools, including an IoT Resource and Service Catalogue and an IoT event debugging tool have been developed. The project was carried out by a consortium of European and Brazilian partners.

EnergyInBalance Solar Energy App Expands User Base

Our Solar Energy app marketed by the EnergyInBalance service has now reached 500 users with solar energy installations. The Solar Energy app uses Internet of Things technology to measure the ongoing energy production from a solar panel installation. The solar energy production is visualised in realtime in an iOS and Android smart phone appp. The EnergyInBalance Solar app also aggregates the total ongoing production from all available installations in Sweden and displays it in realtime to the users.
