Which solar cells do you need?
With the nine different solar cell sets, varying from 110Wp to 960Wp that can be found at the bottom of the page, we offer a suitable set for every situation. But which one suits you best? We list the right package solution for your needs below.
110 to 190 Wp sets
The 110 Wp, 160 Wp and 165 Wp sets are ideal for all trucks. Total power consumption per day is around 0.50 kWh. Looking at the figure below, you can see that you actually almost always generate more than you consume. The 190 Wp set is ideal for inner-city transporters. The total consumption on a day in a transporter is about 0.96 kWh.
220 Wp set
The 220 Wp set is ideal for craft vehicles. A craftsman normally uses 2-3 batteries with a consumption of 0.10 kWh per battery per working day. Since different craftsmen use a wide variety of power tools, the exact calculation of the power required is complex and has to be done on site. In our experience, however, a 220 Wp set is usually sufficient. For optimal use of the solar system, we recommend the additional installation of a consumer battery in combination with an isolating relay and a 2000 W inverter, which provides the necessary 220 V.
380 Wp set
The 380 Wp set is ideal for vehicles with lifting platforms. One lift and descent with a duration of three minutes costs about 0.12 kWh. So when you lift and lower 15 times daily, it costs about 1.80 kWh. Fluctuating charging voltages damaging battery capacity: With the introduction of Euro 6, modern battery management systems can cause problems under certain conditions. A solar system supporting the battery may be the solution and is especially popular in inner-city distribution transport. Fossil vehicle: We recommend a consumer battery connected to the vehicle battery via a separate isolating relay. If the lift already has a battery, it can be used. Electric vehicle: For an off-grid system, we recommend a larger battery, such as a lithium battery LAR 200 or Green Energy’s original T-Box system. The system can be expanded at any time with several solar panels.
640 Wp set
The 640 Wp set is ideal for city buses. City buses have many electrical components such as ventilation systems, various light sources, destination displays inside and outside the bus, and radios and cameras.
All the systems mentioned work with electricity from the vehicle’s battery, which has to be charged by the generator. For buses with diesel engines, our CIGS solar cell system provides 600 kWh for the battery from experience. This means savings of around 600 litres of fuel per year.
The condition is that the solar energy produced is used constantly. In an E-bus, the 24 V system has the same consumption. By eliminating the generator, the battery can be charged more efficiently, increasing the performance of the battery and increasing the range of the bus.
960 Wp set
The 960 Wp set is ideal for coaches. Like city buses, the power consumption of coaches is also very high. There are also additional consumers such as microwaves, refrigerators, coffee machines, hot water tanks and USB connections per seat.
Since coaches usually have multiple generators relieved by the solar cell system, the fuel savings can be much higher than for city buses. In our experience, our solar cells can generate 1,000 kWh. This means savings of around 1,000 litres of fuel per year. We recommend: Installation of a consumer battery and a 4,000 W inverter.
