Additional Enhancement to solarSunda

[dpinney]

TODO

• Change tilt code to 1 box, "-" makes tilt equal the latitude formula from Sunda spreadsheet. Otherwise it's the degrees the user specifies.
• Put in dash logic for "System Array Size (kW-DC)". If dash then use SUNDA multiple of system output size (kw-AC) (it's like 1.3809. it's in the excel). Otherwise use number value in there.
• Port the tilt "-" logic to the other solar models.

QUESTIONS

• Collapsible sections for construction costs?
• Inspection and permits - make it 20*panelSize instead of fixed amount? See Doug's notes? We need Paul and Doug to agree on a formula.

Re: Inspection and permits - make it 20*panelSize instead of fixed amount.

This cost is definitely not linear. Maybe partially linear. Could be try something like:

Permit cost = x (fixed cost) + y*panelsize (variable cost)

Paul could probably figure out what the fixed and variable components should be to make sure it matches with the spreadsheet. Maybe 3/4 fixed and 1/4 variable for the 1 MW template sized system.

Not a critical issue -- just an idea.

Mannan is working on the TODO section. More clarity needed on questions.

A few minutes away from having this imported to all models.

Future TODO: Use a regex that makes sure a degree < 90 is entered; currently a degree > 90 crashes the Sunda model. After testing PVwatts, I expect all the models will similarly crash.

[dpinney]

Inside the tag use

pattern="^(90|[1-8]\d|\d)?$"

Worked like a charm. Was there a reason solarRates currently doesn't have a tilt selection?

[dpinney]

Nah. Tilt=latitude is good for that one. Manual tilt is overkill there.

[mannanj]

Done.
