Solar equipment

Generating electricity from the sun is handled by both complete kits and individual components for homes, cabins, motorhomes or boats. Solar equipment here covers photovoltaic panels, charge controllers, inverters, batteries matched to photovoltaics and additional accessories for wiring the whole installation together. You'll find gear for off-grid and hybrid setups, from small portable sources to more powerful solutions for year-round operation. The individual parts differ in power, voltage and mounting type, so it's easy to build a system to suit your actual consumption and location.

Solar equipment

Producing your own electricity from the sun rests on a few basic parts that together form a working whole. At the heart of every setup are solar panels, which convert sunlight into direct current. They differ in power and cell technology, most often monocrystalline and polycrystalline, with monocrystalline modules usually offering higher efficiency in a smaller area. You can choose anything from small portable panels for travel to more powerful modules for a fixed installation.

The generated energy needs to be regulated and adjusted. Solar charge controllers manage the flow of current to the batteries and protect them against overcharging and deep discharge; they differ mainly in PWM and MPPT technology, with MPPT drawing noticeably more energy from the panels. The controllers are followed by inverters, which convert direct current into 230 V alternating voltage for ordinary appliances. Depending on the wiring, a distinction is made between off-grid inverters for independent systems and hybrid models that work together with the grid.

To store surpluses, batteries built for frequent charging and discharging are used. Most often these are lithium (LiFePO4) batteries as well as gel or AGM lead types, which differ in service life, weight and usable capacity. Capacity and depth of discharge determine how long a setup covers consumption when the sun isn't shining, and in larger setups they depend on the number of appliances and the required operating time.

The individual parts are linked by accessories such as solar cables, MC4 connectors, fuses, brackets and mounting frames. Solar equipment makes sense for cabins without a connection, in motorhomes, on boats and as a backup source for the home. When choosing, it is sensible to start from daily consumption, the space available for mounting and the system voltage, most often 12, 24 or 48 V, so that the components match in power and the whole system works reliably.
