​PV modules

​A PV module consists of many PV cells wired in parallel to increase current and in series to produce a higher voltage. The module is encapsulated with tempered glass (or some other transparent material) on the front surface, and with a protective and waterproof material on the back surface. The edges are sealed for weatherproofing, and there is often an aluminum frame holding everything together in a mountable unit.

PV panels include one or more PV modules assembled as a pre-wired, field-installable unit. The modular design of PV panels allows systems to grow as needs change. 

Half-cell modules have solar cells that are cut in half, which improves the module’s performance and durability. When solar cells are halved, their current is also halved, so resistive losses are lowered and the cells can produce a little more power. Smaller cells experience reduced mechanical stresses, so there is a decreased opportunity for cracking. Half-cell modules have higher output ratings and are more reliable than traditional panels.

​Photovoltaic Benefits

• Solar power lower utility bills and insulate  from utility rate hikes and price volatility due to fluctuating energy prices.
• Installing a solar system increases property value and home resale opportunities
• A solar power system allows to take advantage of available tax and financial incentives.
• Because they don't rely on miles of exposed wires, residential PV systems are more reliable than utilities, particularly during bad weather.
• PV modules have no moving parts, degrade very slowly, and boast a life span that isn't fully known yet, but is measured in decades. Lebensdauer, die noch nicht vollständig bekannt ist, aber in Jahrzehnten gemessen wird.
• Solar electric systems are quiet, reliable, fossil-fuel free.
• Unlike mobile power generators, solar energy avoids greenhouse gas emissions.

Inverters

​An inverter is one of the most important pieces of equipment in a solar energy system. It’s a device that converts direct current (DC) electricity, which is what a solar panel generates, to alternating current (AC) electricity, which the electrical grid uses. In DC, electricity is maintained at constant voltage in one direction. In AC, electricity flows in both directions in the circuit as the voltage changes from positive to negative. Inverters are just one example of a class of devices called power electronics that regulate the flow of electrical power.

Fundamentally, an inverter accomplishes the DC-to-AC conversion by switching the direction of a DC input back and forth very rapidly. As a result, a DC input becomes an AC output. In addition, filters and other electronics can be used to produce a voltage that varies as a clean, repeating sine wave that can be injected into the power grid. The sine wave is a shape or pattern the voltage makes over time, and it’s the pattern of power that the grid can use without damaging electrical equipment, which is built to operate at certain frequencies and voltages.

​Storage systems

Solar batteries store energy generated by your panels for use when you actually need it. Solar batteries are an alternative (or addition to) feeding energy back to the grid and can help you make your house or facility somewhat immune from power outages and even help take it off-grid entirely.

Inside the solar battery, chemical reactions take place to store the surplus electricity as potential energy. So, when electricity is needed when the sun isn’t shining, such as during nighttime or overcast days, the stored energy is converted back into usable electricity and readily supplied to your home.

By allowing home or business owners to maximize their solar energy consumption, solar batteries increase the reliability of solar power systems and decrease dependence on the conventional power grid. The ability to store and utilize solar energy even during periods of limited sunlight makes solar power a more practical and efficient choice for renewable energy.

​E-mobility

Electromobility is the principle of using electric propulsion for a wide range of transportation types. This includes cars, buses, trucks and off-road vehicles, as well as ships, ferries and other sea going vessels.

E-mobility allows us to move away from CO2-emitting fossil fuels towards energy supplied from electrical power sources which are, in turn, charged through the electricity grid. By decarbonizing the transport sector, electromobility will create a cleaner, healthier and more affordable future for everyone.

Electric vehicles cost less to run over their lifetime than traditional cars with combustion engines. This reduced cost stems largely from taxation regimes, fewer moving parts, and lower fuel costs.
