Add a Solar calculator with offline NASA POWER data
Estimates a solar array's typical-year production from a location and the
panels; everything else has defaults under an optional "Fine-tune" section.

The model works from 12 monthly averages: Klein's average day per month, the
Erbs monthly diffuse fraction, Collares-Pereira & Rabl / Liu & Jordan hourly
split, HDKR transposition for fixed, single-axis and dual-axis arrays, then
PVWatts' ASHRAE incidence loss, SAPM cell temperature, DC power, system
losses and optional inverter.  "Best for the year" and "Best for winter" sweep
the tilt.

Sunlight, diffuse, albedo and temperature come from NASA POWER's 2001-2020
climatology on a 1 degree grid, packed into app/public/data (3.1 MB, ~1 MB
gzipped) by scripts/build_solar_climatology.py and fetched only when the
calculator opens.  Users can replace it with their own monthly values.

Every setting lives in the URL, with defaults left out, so the Share button
shares the whole configuration.

Against PVWatts v8 for a 1 kW fixed array: Phoenix +0.6%, Seattle +8.8%,
Anchorage +8.0% annually; these are recorded as tests.

Getting Started with Create React App

This project was bootstrapped with Create React App.

Available Scripts

In the project directory, you can run:

npm start

Runs the app in the development mode.
Open http://localhost:3000 to view it in your browser.

The page will reload when you make changes.
You may also see any lint errors in the console.

npm test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

npm run build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

npm run eject

Note: this is a one-way operation. Once you eject, you can't go back!

If you aren't satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.

You don't have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
