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.

Does proficad support photovoltaic circuit diagrams?

ProfiCAD supports the drawing of photovoltaic circuit diagrams. In addition to the common electrical engineering symbols, the library includes symbols such as solar cells, photovoltaic panels, solar collectors, inverters, etc. Should you need more symbols, you can create them in the symbol editor. Some sample drawings (click for full size):

What are the design criteria for a grid connect PV system?

The actual design criteria could include: specifying a specific size (in kWp) for an array; available budget; available roof space; wanting to zero their annual electrical usage or a number of other specific customer related criteria. Determining the energy yield, specific yield and performance ratio of the grid connect PV system.

How do I design a PV Grid connect system?

The document provides the minimum knowledge required when designing a PV Grid connect system. The actual design criteria could include: specifying a specific size (in kWp) for an array; available budget; available roof space; wanting to zero their annual electrical usage or a number of other specific customer related criteria.

How do you calculate a derated output power of a solar module?

A solar module has an derated output power = Module power @ STC x Derating due to manufacturers tolerances x derating due to dirt x derating due to temperature. The actual DC energy from the solar array = the derated output power of the module x number of modules x irradiation for the tilt and azimuth angle of the array.

How do I choose a solar inverter?

Determine where the inverter will be located. Determine the cabling route and therefore estimate the lengths of the cable runs. Full Specifications of the system including quantity, make (manufacturer) and model number of the solar modules and inverter. An estimate of the yearly energy output of the system.
