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):

How is a PV array sized for a stand-alone system?

The PV array for stand-alone systems is sized to meet the average daily load during the critical design month. System losses, soiling and higher operating temperatures are factored in estimating array output. The system voltage determines the number of series-connected modules required per source circuit.

What are the sizing principles for grid connected and stand-alone PV systems?

The sizing principles for grid connected and stand-alone PV systems are based on different design and functional requirements. Provide supplemental power to facility loads. Failure of PV system does not result in loss of loads. Designed to meet a specific electrical load requirement. Failure of PV system results in loss of load.

How to design a PV array?

The PV array design will be dependent on the inverter style and the chosen system layout. Safety requirements, inverter voltage limits, federal regulations, and the maximum and a minimum number of modules per string will need to be calculated.

What factors limit the size of a solar photovoltaic system?

There are other factors that will limit the size of your solar photovoltaic system some of the most common are roof space, budget, local financial incentives and local regulations. When you look at your roof space it is important to take into consideration obstructions such as chimneys, plumbing vents, skylights and surrounding trees.
