How do I design a photovoltaic and solar hot water system?

Provide an architectural drawing and riser diagram for the homeowner showing the planned location for future photovoltaic and solar hot water system components. Space requirements and layout for photovoltaic and solar water heating system components should be taken into account early in the design process.

Which DC isolator should be supplied by Viridian solar?

Provided by Viridian Solar The d.c. isolator must be double pole and rated for the system voltage and current deg increments. If required, this device could be supplied by Viridian Solar at extra maxima as calculated from the PV array. It should be load-break rated.

How much space does a photovoltaic system need?

Photovoltaic modules installed on the ground or on a flat surface occupy an area of approximately 20 m2/kWp, avoiding shading between the rows of modules. The design of a photovoltaic system, from the public operator’s network to the photovoltaic modules, requires careful planning and compliance with local regulations.

How much space does a photovoltaic module occupy?

Photovoltaic modules installed on a sloping roof or facade occupy an area of approximately 8 m2/kWp. Photovoltaic modules installed on the ground or on a flat surface occupy an area of approximately 20 m2/kWp, avoiding shading between the rows of modules.

What are the requirements of Viridian solar inverter?

Provided by Viridian Solar. The inverter must be treated as standard electrical apparatus and earthed as per BS 7671 if Class 1. It must carry a Type Test certificate to the requirements of Engineering Recommendation G83/1 or comply with all other parts of ER G83/1. must switch all live and neutral conductors.

How do you rated a PV inverter cable?

Cables must be rated, as a minimum, to the voltage and current ratings derived from the PV array. Standard de-rating factors must also be applied (BS 7671). Cables should be sized such that overall voltage drop at stc between the array and the inverter is <3%.
