installation of Solar PV and EV charging at Price Fencing, Merthyr

ScopeDesign a Grid Tied 36.86 kWp Photovoltaic Array and EV Charging Stations for Price Fencing & Landscaping Limited, Maesgwynne Industrial Estate, Cefn Coed, Merthyr Tydfil, CF48 2SD. The PV Inverter and PV/EV Distribution Board to be located in storage room at rear of front reception area.PV System Design.The PV system will incorporate the following points within the design.• Inverter must have minimum 12-year warranty• Type 2 surge protection built into the inverter.• Tier 1 Monocrystalline Modules with a Module Efficiency greater than 20%• Modules to have a 12 Year Warranty for Materials and Processing.• Modules to have 25-year Power output Warranty (Power Output Tolerance - ≤2% Year 1 & ≤0.55% years 2 to 25)• Safe Touch voltage technology built into the design to reduce DC voltage at loss of inverter power.• Optimisation to mitigate all types of module mismatch-loss from manufacturing tolerance to partial shading.• Optimisation to ensure maximum generation of the PV modules at panel level, minimum one for two panels.• Inverters and optimisers be manufactured from the same company• Firefighter safety switch interconnected with the onsite fire alarm panel. Safety switch to reduce string voltage to below safe DC touch voltage on alarm.• Modbus meter with CT’s at intake position to monitor Import / Export via online monitoring system.• For ease of maintenance, module level monitoring is to be included with connection to internet• By isolating the AC supply the DC circuit must reduce below DC touch safe level• Inverter selection must have built in arc fault detection according to UL1699B• Arc fault detection must reduce DC current and DC voltage.• Trapezoidal Sheet mounting system.• G99 Application for connection.• MCS registration.EV Charge PointsThe Electric Vehicle Charge points will incorporate the following in the design.• 1 x Twin 7.4kW Type 2 Mode 3Charge Point.• 1 x Single 22kW Type 2 Mode 3 Charge Point.• Key activated charging.• Built in PEN Fault Detection (No Earth Rod Requirements)• Smart Charge Point Regulations 2021 Compliant.• OZEV approved.• Warranty – Minimum 3 yearsElectrical InfrastructureA new 3 phase distribution circuit to be installed tapping off the existing Bus Bar Chamber supplying a new 3 phase PV & EV Distribution Board installed within the Storage Room. The new submain cable will have a fused switched isolator at connection to Bus Bar for isolation. The new PV & EV Distribution Board will supply power to all new components. All distribution circuits to be supported with independent containment and bracketry.AccessAccess to be supplied via scaffold with edge protection to all areas of the roof where proposed PV array is to be installed. Scaffold to have all safety permits and certificates in place before access to work granted.A site visit to site is recommended to confirm design requirements prior to pricing.NOTE: To register your interest in this notice and obtain any additional information please visit the Sell2Wales Web Site at https://www.sell2wales.gov.wales/Search/Search_Switch.aspx?ID=123221.
