Solar Hot Water Systems

This product category applies to PVRS credit RE-R1: Minimum Energy Performance and can assist for the optional credit RE-3 Renewable Energy to achieve a higher Pearl Rating. These credits require detailedcalculations of the renewable energy generation potential along with drawings and schematics of the proposed solar hot water systems.

RE-R1 Requirements

RE-R1 Minimum Energy Performance requires 50% of the total yearly hot water energy usage (kWh) associated with hot water generation for all the villas including staff usage to be generated from renewable sources.

Submission Process

In order to demonstrate compliance with the credit requirements, project teams can either use the standard submittal templates with all supporting documentation or the EVPD Submittal Template : Solar Hot Water Systems below.

• EVPD Submittal Template : Solar Thermal Hot Water Systems

This spreadsheet contains a complete schedule that is automatically generated including all relevant information for inclusion for the PW-R1 submission as follows:

• Manufacturer

• EVPD and Manufacturer Reference Numbers

• Flow Rate at Required Pressure

If you want to use a product that is not on the EVPD, please follow the Conventional Villa Product Selection Pathway.

Estidama Villa Product Database - Solar Hot Water Systems

The UPC is currently working with manufacturers and distributors to develop standard sizes of solar thermal panels for 4, 5, 6, 7, 8, 9 and 10 bedroom villas. All of the systems listed in the Estidama Villa Product Database (EVPD) - Solar Thermal Hot Water Systems have been deemed compliant by the UPC irrespective of their actual contributions to the yearly hot water energy usage. Where villas exceed 10 bedrooms, the design and development team should contact the manufacturer directly to select the appropriate product.

The specific detail of the design must always be completed in conjunction with the respective manufacturer/ distributors recommendations; however, collector sizes are not permitted to vary under the EVPD program.

The system designs are based on the following:

• 2 people for the first bedroom and then 1 person for subsequent bedrooms (e.g. a 4 Bedroom villa will have an occupancy of 5)

• 50 litres/person of hot water demand is required per day

• Cold Water Inlet Temperatures: Winter 14oC / Summer 30oC

The Estidama Villa Product Database (EVPD) - Solar Thermal Hot Water Systems provides the following information:

• Manufacturer name

• EVPD Reference

• Solar Thermal Hot Water System Type

• Manufacturer's product reference

• Solar System Panel Area & Tank Volume

• Standard Warranty Period

• Expected Lead Times

• Contact Details (including approved distributors)

Estidama has also ensured that distributors have system schematics, layout drawings, system simulations, detailed product data etc. for their listed products (as listed in the EVPD). For simplicity links to the system's schematics / layout drawings relating to the published Solar Hot Water Systems are organized in the following table.

The links provided in the table below contain the EVPD of the various solar hot water systems that have been deemed "technically compliant" with the PVRS requirements:

Notes:

(1) This file contains the following information : EVPD reference, number of bedrooms, system type, manufacturer product reference, panel area, hot water storage volume, calculated solar hot water contribution, standard warranty, expected lead times, schematic / layout drawing filename, sales / distributor contact details.
