House 15kVA Solar System with Solar Panel 250W

Product Description40W 50W 80W 100W 150W 200W 250W 300W Photovoltaic Poly Solar Panel Module with Ce TUV ISO IECBrief Introuction Mono Solar PanelTo produce a monocrystalline silicon cells, absolutely pure semiconduction material is necessary. Monocrystalline rods are extracted from melted silicon and then sawed into thin plates.This production process guarantees a relatively high level of efficiency silicon and makes monocrystalline panels one of the most efficient, producing smaller solar cells, and therefore smaller panels. Monocrystalline works very well in bright cool conditions.Poly Solar PanelPolycrystalline solar panels are also made from sillicon.However,instead of using a single crystal of silicon,manufacturers melt many fragments of silicon together to form the wafers for the panel.Polycrystalline solar panels are also referred to as "multi-crystalline"or many-crystal sillicon.Because there are many crystals in each cell,there is to less freedom for the electrons to move.As a result,polycrystalline solar panels have lower efficiency ratings than monocrystalline panels.ApplicationsOn-grid residential roof-topsOn-grid commercial/industrial roof-topsSolar power plantsOff-grid systemOther on-grid applicationsTechnical data: Electrical Parameter Standard Test Conditions (STC)TypeWW-250s6Maximum power (Wp) 250wpMaximum power voltage (V) 30.2Maximum power current (A) 8.27Open circuit voltage (V) 36.7Short circuit current (A) 8.84Number of cells (Pcs) 60Size of module (mm) 1640*990*40mm( 156x156mm cell)Maximum system voltage (V) 1000Temperature coefficients of Isc (%) 0.065+/-0.015%/ºCTemperature coefficients of Voc (%)-(2.23+/-0.1)mv/ ºCTemperature coefficients of Pm (%)-(0.5+-0.05)/ ºCTemperature coefficients of Im (%)+0.1/ ºCTemperature coefficients of Vm (%)-0.38/ ºCTemperature Range-40ºC~+85ºCTolerance Wattage (e.g. +/-5%) +/-3%Surface Maximum Load Capacity30m/s(200kg/sq.m)Allowable Hail Load steel ball fall down from 1m heightWeight per piece (kg) 18.2Junction Box Type Pv0805Length of Cables (mm) 90Cell Efficiency (%) >17.5%Module Efficiency (%) >17%Output tolerance (%) +/-3%Frame (Material, Corners, etc.) AluminumStandard Test ConditionsAM1.5  100mW/CM2/ 25'CWarranty 10years product warranty and 25 years 80% of powerFF (%) 75%PackingAccording to customer's requirementPacking and ShippingProject  Customer Question & AnswerWhy Choose Wind Wing SOLAR1) Excellent quality, competitive price, prompt delivery, on-time service and good reputation.2) Fast sample delivery3) Low minimum order4) Fast shipment in 15~20 days on receipt of your payment.5) We handle all the components needed for utility-connected systems, or for powering independent homes and remote industrial sites.6) We offer knowledgeable tech support before and after the sale.7) We pass the authentication of ISO, RoHS, TUV, and CE approvalFAQ1.
