Why SEDI PV Modules?
SEDI PV modules weigh as low as 2.5 Kg/m2 compared to conventional glass top modules which can weigh up to 30 Kg per module. Conventional modules additionally require heavy metal supports to mount them on.
Our special manufacturing process ensures that our solar panels are only 2-3mm thick. Conventional panels are around 50mm thick, and when installed on their metal support structure, can be as high as 300mm, making them unsuitable for windy conditions, mobile solar, or discrete installations.
The SEDI Modules are very flexible, allowing them to conform to the contour of the substructure of the building or project, unlike glass top conventional modules that are brittle and fragile and therefore more prone to micro-fissures and cracks.
Shock absorbing, fully laminated surface provides SEDI modules a very high level of durability against weather, accidents or malicious attempts. Unlike conventional panels that are extremely brittle, fragile, heavy and are easily damaged during transportation and installation.
All SEDI modules are designed with mono-crystalline half cut Tier 1 cell technology and offer much better yield in low light and shadow by virtual of a unique nano-surface lenticular structure allowing light refraction. Also the nano-layering gathers diffused light more efficiently.
All SEDI modules are designed with mono-crystalline half cut Tier 1 cell technology and provide better energy yield in any orientation*, by virtue top quality components, revolutionary polymer lamination and more efficient utilization of sunlight by the refractive effect generated by the lenticular surface.
SEDI modules can be glued, screwed or riveted onto the surface of any building, roof or structure. As long as direct sunlight hits the panel it can be mounted in any inclination as well. It does not need any additional metal support rails or substructure. SEDI reduces cost and time of installation greatly.
SEDI modules are able to extract heat very efficiently on the surface of the module itself, unlike conventional modules which can only dissipate heat from the underbelly of the module. This allows flat installation of SEDI modules on surfaces without loss of efficiency or degradation.
SEDI modules have no Aluminium framing on them, unlike conventional panels. Hence conventional panels critically must be grounded at regular intervals, to protect installers against electrical current leakage on a string. SEDI modules do not require any grounding and are intrinsically much safer to install and maintain. Being lighter and non-glass, professional and third party insurance for installers is much lower.
SEDI modules can be manufactured in any size* or color** in order to customize them to fit the demands of a project. Certain minimum order quantities and efficiency degradation allowances must be considered by the installer in these cases.
SEDI technology offers superior performance and offers an unsurpassed 25-year product warranty and 40-year linear performance warranty.
SEDI PV modules compared to conventional PV modules
Nearly 95% of PV Modules made today worldwide are based on the above architecture with minor improvements in crystals, perc, diodes, silicon impregnation techniques, busbars.
Conventional PV modules weigh between 25-30kg per module. In addition, the underlaying steel/Al rail support structures required to keep these modules at the perfect tilt and position add another 7-12Kgs per sqmtr. This weight implies that conventional modules may not be suitable for lightweight, old or heritage roof structures or even structures having sensitive surfacing like insulation or waterproofing.
Conventional PV modules employ a thick tempered glass surface to allow sunlight to hit the solar cells below. Glass by nature is brittle and fragile and can be easily cracked during transportation or installation. Further sand storms, hail storms and even birds can cause abrasion, cracks, micro-fissures or breakage to the glass surface, rendering the solar module inoperable.
Conventional PV modules require higher maintenance due to their fragile nature. Micro-fissures and hotspots develop more often. Cleaning the surface regularly with costly distilled water is essential. Dusty conditions need more frequent cleaning since glass is inherently static and attracts dust particles on its surface. Cost of maintenance is relatively high.
Solar technology, though termed as clean energy, is inherently an inefficient energy source, providing only 20-22% output. This implies very large areas of land required to generate even moderate amount of energy. At an average 6-8 acres are needed to create 1MW solar energy. With cost of real estate escalating, and solar farms replacing conventional forests and farmland, this is a hard balance to maintain.
Conventional PV modules have to be handled with care and installed accurately. Cost of installation is high considering transportation, mechanized lifters at site, installation of steel/Aluminium structural supports, civil works for foundation, soil survey, electrical grounding, and sometimes reinforcement in case of existing load bearing structures.
Solar modules inherently degrade through their lifetime. Depending on ambient conditions the average life of a solar module is 15-25 years. Factors that speed up degradation in Solar modules are heat, humidity, dust, PIDs effect and quality of maintenance. Conventional panels tend to degrade faster in hot climates due to the combination of glass top and Al framing which is believed to accelerate degradation.
Solar technology worldwide in the 2020s have reached a plateau in terms of efficiency. The average efficiency of Tier1 conventional monocrystalline PV modules today ranges within the 19-22% bandwidth, in-spite of a number of innovations in composition, and design. Also, this level of efficiency is only achieved under optimal operating conditions in terms of angle of tilt and orientation, temperature, humidity, air quality etc.
Testing
SEDI Solar PV Modules are tested rigorously to meet international standards and especially German standards of safety and performance. SEDI Modules are certified for IEC 61215/61730/61701/62804-1/62716, EN-13501-5 In addition, SEDI Modules undergo rigorous physical testing to ensure its flexibility and ruggedness is sustainable even in the most adverse conditions throughout its guarantee period.
