What does LCOE mean?
LCOE is a short form for levelized costs of electricity. It is a ratio between all the costs of a power plant and all revenues for electricity. So, the LCOE take costs of building, operating and dismantling of the plant as well as possible fuel ...
What is BOS?
BOS stands for "Balance Of System". Most of the time it includes all the components of the PV system except the modules (mounting systems, inverters, cables, fuses, disconnecting devices, weather sensors, monitoring sensors...). When we calculate the ...
Is negative grounding required?
Negative grounding, although recommended by the module installation manual, is not mandatory. Furthermore, negative grounding of transformerless "TL" inverter is not allowed. For more information on our products, please visit : ...
Can the modules be installed horizontally? Does this have an impact on the warranty?
Generally there is no impact on the warranty but this should be checked for each manufacturer. However, horizontal installation does impact performance negatively as the modules get dirty more quickly due to water stagnation on the modules. This can ...
Can I drilla hole in the frames of my modules?
Drilling additional holes as part of the module reduces the mechanical resistance of the module. Unless otherwise advised by the manufacturer, drilling holes in the frame and any other physical modification is prohibited and will void the product ...
Can I protect 2 strings of modules with the same fuse?
The calculation rules of standard UTE C5712 make it possible to define the maximum number of chains per protection device using the maximum return current of the Irm module and the short-circuit current Isc. This information is generally given on the ...
What rules should I follow to install my modules?
UTE C15712 standards and the manufacturer's installation manual contain all the information necessary to properly implement your PV modules. For any specific questions, please contact us. For each manufacturer, refer to the manual available in the ...
What is a good bifacial project? What should I watch out for?
While designing a bifacial project we can distinguish 3 main parameters. 1 / the bifaciality coefficient which is intrinsic to the cell technology used. It is the ratio of rear power to front power. FYI, polycrystalline (~ 65-70%), monocrystalline ...
What is eco participation?
Eco participation is the application of the European directive on Waste Electrical and Electronic Equipment (WEEE) which already existed for televisions, refrigerators and other consumables which is now applied to photovoltaic panels. A given amount ...
