In the Netherlands, new feed-in fees introduced in August 2024 are significantly affecting solar system owners. One homeowner in southern Holland has demonstrated how to reduce the impact using solar-powered heating.
A German farmer uses his abundant surplus from his photovoltaic array to heat water with a heating rod. He manages completely without electricity from the grid – even in winter. Read about how it works.
The i-Shelter protects inverters, a new PVT combi module as well as a curved solar roof tile and an integrated roof module. These are our top products of the week.
Soblue's combined photovoltaic and thermal modules, PVT in short, are now certified according to the Solar Keymark and thus qualified for the most important subsidy programmes. The test was conducted by the KIWA testing institute.
The company Maustronik from Kassel in Germany has developed a new concept to utilise the heat under the solar modules efficiently. The new PVT principle is very promising: Roof heat exchangers are installed underneath the modules at the top and bottom ends of a photovoltaic system.
In the spring of 2023, Vitramo's VH series heating elements were tested by the Technical University of Dresden in accordance with the IEC 60675-3 standard - and they all passed.
In Schallstadt, southwest of Freiburg, architect Rolf Disch has constructed buildings that generate more energy than they consume. Solar modules in the facade provide most of the solar power for heating and mobility.
The owner of a detached house has switched to solar-electric heating. Two power controllers from My PV control the energy flows - including for the hot tub in the garden.
Elio offers planning, consulting and key components for solar-electric buildings. The overall concept for a highly independent energy supply in new and existing buildings is based on digitally controlled infrared heaters, a domestic hot water heat pump and photovoltaics.
In addition to a photovoltaic module, new PVT heat pump collectors from Consolar and Triple Solar have an air-brine heat exchanger on the underside of the collector.
The Solteq solar roof is more than an aesthetic solar installation where the photovoltaics are invisible. It is also a solar thermal system that spans the entire roof.
Many of My PV's products that were sold out in recent months are now available again. The expansion of production capacities is bearing fruit.
SMA and Samsung will link their communication. This will allow heating devices such as heat pumps from Samsung to be integrated into SMA's energy management system.
The company Tado is expanding its product portfolio and introducing a heat pump control with the Heat Pump Connector and the Balance Heat Pump app function.
More than 2,000 parabolic mirrors generate the heat Avery Dennison needs for the production of pressure-sensitive adhesive products. A storage unit and a control platform ensure that the solar heat is available at all times.
With Tempusvolt Pro, the German company Herotec refines its portfolio of electric floor heating systems. In the new screed heating mat, the heating conductors with a robust outer sheath are fixed to a self-adhesive glass fibre fabric. This allows quick and easy installation.
The Austrian company My-PV presents the AC Elwa 2 electric heating rod, which converts surplus solar energy into hot water.
The performance after one year of the first completely solar-electric building has surpassed all expectations. The new company building of My PV is not only supplied with 60 per cent of its own solar power, but actually made almost 16,000 euros in profits.
My PV has further developed its AC Elwa-E solar electric heater. It has been enhanced with new features, a Wi-Fi interface and a display.
Data centers are often perceived as power guzzlers. However, beyond digitization, they can generate further added value for the environment and society.
The opportunities and challenges of a renewable local heating supply and the move away from fossil - Russian - gas became clear at an on-site meeting in Potsdam. One hurdle is suitable land for more solar thermal power plants.
The principle of heat pumps is simple: with a certain amount of electricity, they raise the temperature of a low-temperature heat source to a higher, usable level. In this way, they generate much more heat than would be the case if electrical energy were converted directly into heat.
With the new Home Energy Package from LG Electronics, homeowners generate renewable energy and use it around the clock in the entire home.
The PV supplier is becoming a total energy service provider. Because the PV market and customer needs are changing, customer orientation is becoming a major issue in the energy industry. A software solution helps installers and customer consultants stay on the ball. A practical report from Eturnity.
A new series of three-phase inverters, some integrated solar roof tiles, a heat pump with PVT collectors and a new half-cell module for European market. These are our top products of the week:
