CheckWatt extends business to Africa

African countries face the need to meet a fast-growing energy demand but its nations can pick from a portfolio rich in renewable energy sources, including water, sun and wind, among others. Building on experience gathered around the globe Africa can design it’s energy sector for the future.

Half of the continent has solar radiation intensities of more than 7000 kWh/m2/day, the perfect premise for utilizing solar power. Renewable energy sources offer additionally more independence from fossil material, improved resilience and sustainability.

CheckWatt, one of CNets subsidiaries, offers configurable energy related solutions for different needs. In the last year CheckWatt has extended their business to Europe. The companies expertise and experience is leading in the Swedish market and internationally competitive. CheckWatt is proud to announce that they have entered their first contract in Kenya, which entails the deployment of a new solar energy installation in Kenya.

CheckWatt adds energy storage services

CNets spin-off company CheckWatt is expanding services with solutions to store energy and manage usage intelligently.

The fast growing market of private solar installations and electrical vehicles are followed by extended needs regarding the electrical infrastructure but also offer new possibilities for utilization. In 2019, the market for electric grid ancillary services was approximately 1.5 billion SEK. Svenska Kraftnät forecasts that it will double twice by 2023, driven by the growing share of intermittent power production (solar and wind) within the electricity mix and an increased integration within Europe (regulating power as an export product). Meanwhile the fees for the electrical network infrastructure grow significantly without smarter network solutions, so smart solutions that avoid unnecessarily future costs are needed, a conclusion that the European trade association has come to: “Smart storage and control before cable!”

With already more than 200.000 electrical vehicles registered in Sweden, each about 10 kW on average, these have already the same peak power as 2 nuclear power plants.
Electric cars are fundamentally changing the energy system, and they are rather an asset than a burden. The advantage of electric cars is that they do not have to be fully charged all the time. The effect can be adapted to the needs of the electricity network, cushioning peaks through utilizing off times.

EMS (Energy Management System) is a service for energy-related data and smart control for hybrid inverters (photovoltaic systems with connected battery storage for example) and electric car chargers that can minimize power-related costs locally in the building and perform frequency regulation for Svenska Kraftnät, which generates revenue for the owner.

CheckWatt enters cooperation with Car chargers

CNets spin-off company CheckWatt is expanding its product portfolio to meet the growing popularity and needs of electrical vehicles (EVs). Sweden is ranking among the world’s top ten market for best-selling plug-ins since 2015.

In December 2020 a total of 217,704 plug-in vehicles have been registered, 148,889 plug-in hybrids, 62,870 all electric cars and 5,945 all electric vans have been registered in Sweden since 2011. As EVs are actively supported by the government with financial grants and charging at home is cheaper than petrol, diesel or public charging more home owners are looking for smart solutions. CheckWatt does not only want to offer homeowners a solution to charge their cars, but also to manage their electrical home installations, solar installations and to maximize savings reducing power-related costs. Solutions enable users to visualize charging together with other energy-related data. For starters CheckWatt initiated a collaboration with EpSpot and Zaptec, further collaborations are being negotiated.

EnergyInBalance News

EnergyInBalance has published this week a Newsletter with new releases and the latest news in the Energy sector. Based on an algorithm that takes into account the history of over 4000 solar installations that are represented by CNet’s spin-off company Checkwatt, a unique “fingerprint” for each plant is created. Based on this fingerprint derivations in the performance of each installation can be detected fast and without knowing local conditions such as slope, direction and local shading it can detect abnormal electricity production that is likely due to a fault in the plant.

The service offers owners the detection of real-time operational disruptions and notifications about even small deviations, minimising the effort for maintenance and shortening the time of production losses. The service will be launched in autumn and requires no additional equipment.

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.

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.
