Wind Power
The energy potential from wind is caught by vertical or horizontal rotor-blades and transformed into electric energy by a generator within a mechanical process. Small wind turbines are used in residential areas. These can generate energy independent of weather conditions and seasons. A wind power system is a real alternative to photovoltaics.

Solar Heat
The sun (solar) is pure energy. Parts of this can be transformed into warmth (thermal). Solar collectors capture the warmth of the sun on a concentrated surface and introduce it into a thermal cycle so that it can be used (in the household, for example).

Photovoltaics
The photovoltaic (PV) effect, which is also known as photovoltaics, is a process during which visible irradiation from the sun (light particles or photons) are transformed into electric energy (volt). About 60 elementary solar cells constitute a PV module. Environment-friendly electric energy can be generated with a few modules which have been integrated into a system.

Solar Carport
A solar carport is more than a protection for your vehicle against weather conditions. Equipped with PV it becomes an energy generating system. This way, it is possible to provide an electrically powered vehicle with direct environmentally friendly energy. The energy can also be used in the house or fed into the public electricity grid.

LED Light
The LED technology is a very efficient electric lighting technology. With an optimized temperature management LEDs are expected to work in conditions of normal usage for about 50,000 hours. VOLTPOOL relies on good and robust components which also anticipate the design for all areas of use.

Infrared Heater
An infrared heater makes use of a very effective technology to produce warmth from electric energy. Immediately after switching on the device heat is discharged through radiation and reflection without warming the air. As opposed to common heaters, the infrared heater is an efficient way of heating with electricity.

Heat Pump
A heat pump is a thermo-mechanical system which extracts low temperature thermal energy from the surrounding air, water or ground and emits it with a higher temperature after processing in a cycle. A heat pump is an excellent solution for the use of warm water or for supporting the heating system.

Charging Station
A charging station is a piece of electro-technical equipment, i.e. an enlargement of a solar carport. The battery of an electric vehicle can be charged with locally produced energy. A charging station can also be used independently of a solar carport. VOLTPOOL generally relies on components which use the advantages of renewable energy sources.

Hot water storage tank
A hot water storage tank is a container which is thermally highly insolated. It is suitable for the storage and output as well as the production of warm water. Depending on the thermal source other names such as buffer storage, electric boiler etc. can be applied. VOLTPOOL relies exclusively on technologies that use renewable energy sources such as solar collectors or heat pumps.

Energy Management
The ideal organization of (optimally) self-produced energy helps to use this energy in an economic and consumer-optimized way. A gentle use of energy resources contributes to CO2 reduction and protection of the environment.
Learn more
Inverter
In order to use electricity produced by photovoltaics and some wind systems in the household it needs to be transformed directly after it has been generated. The inverter is a device which transforms direct current into alternating current and renders it applicable for local electricity consumption. It also regulates the optimal network integration into the power grid.
Battery storage
A battery enables an effective storage of electric energy from renewable sources. This way electric devices can be provided with green energy even at times when energy production is impossible or insufficient. VOLTPOOL relies on three battery technologies: lead, lithium and vanadium.

Location consulting

We can advise you of conditions to produce optimum yields

The returns of own PV energy generation depend on different factors which can influence the optimal working process in a positive or negative way. These are, among others, solar insolation and the amount of sunny hours, i.e. those hours in which the sun shines onto the surface of the earth without any distraction by clouds, for example.

Orientation

The optimum orientation of a roof is southwards; the sunshine duration/ day is longest here. Westward or eastward orientations can also be exploited with PV technologies. Weaker irradiation, however, is most probable here.
 

Roof inclination

In Germany the optimum roof tilt is between 30° and 60°. In the North the sun is lower than in the South. Modules should be installed with slightly steeper tilts there. In the summer the sun is higher than in the winter, returns are therefore higher in the months of the summer when the modules have a flatter tilt. During winter higher power returns can be generated when the modules have a steeper tilt due to the flatter radiation angle. The performance loss of a system which has no southward orientation is higher, the steeper the roof is. Differences in orientation and thus losses of an optimum performance can be balanced with a higher number of collectors and the optimized use of equipment with specific capacities.

The slanting roof is most adequate for the technology of photovoltaics. Other roof types can also be equipped with PV, they just need more thought as to how modules can be fixed. With on-roof systems the modules are attached with metal constructions. This system is more cost efficient, the wind cools the modules. With roof-integrated systems the modules are attached to the roof-construction, i.e. integrated into the roof. This system is more elegant and the modules are protected better from weathering. It is more complicated and expensive to fixe modules into an integrated system than it is with on-roof systems.

Flat roofs can also be exploited for PV technology.  The collectors are attached with metal carriers. Due to shadowing conditions the modules are fixed with bigger distances to each other. For this a big surface is necessary. The modules are fixed with the ideal angle for irradiation, their surface is exposed to the wind.

Shadowing

Shadows on the collectors of a PV system can influence the returns to a large extent. Before installing a PV system, it is necessary to check whether the surface, on which the collectors are supposed to be fixed, is free from shadowing throughout the year. Shadow casters are chimneys, roof windows but also trees, mountains and neighboring houses etc. Usually a PV system is installed to last for about 30 years. It might be worth inquiring whether the neighbours have plans to extend their house which could then become a shadow caster to your PV system or to what extent trees will grow. If you are planning to cut down a tree, please contact your municipality, you often need a special permission for this kind of activity. For optimum energy yields the direct sun irradiation is needed. This means that when the sun shines directly onto the collectors of your PV system, this is an optimum condition for high energy yields. Shadowing, however, can often not be prevented, for example if there are clouds in the sky. In this case solar irradiation is indirect. Green energy can still be generated, the conditions are, however, no longer optimal.

 

 

Irradiation

The optimum angle of irradiation of the sun onto PV modules is 90°. This angle can be reached in the summer when the modules are flatter (ca. 30° tilt) as the sun is higher. When the irradiation angle of the sun is flatter in the months of winter, the collectors need to be positioned in a sharper angle (ca 60°) for optimum yields. During installation tracking systems can be fixed, which adapt the angle of the modules automatically to that of the solar irradiation. This system can, for example, balance an unfavourable angle of the roof. It is necessary to check individually to what extent the investment into a tracking system makes sense. We recommend this kind of system for professionally used plants.

Small wind turbines

In order to guarantee the profitability of small wind turbines, certain location criteria need to be fulfilled. We measure and analyse the wind potential for the generation of electric energy for your location. The conditions of the location are elementary: wind power restrictions due to trees, neighboring houses etc. can occur. We are happy to advise you to the conditions of your location. Contact us.
