Initialize Wind attributes from a hash. Wind attributes currently are limited to power capacity.

parameters:

hash - Hash - A hash containting a :size_kw key/value pair which represents the nameplate capacity in kilowatts (kW)

def initialize(hash = {})
  hash.delete_if { |k, v| v.nil? }

  @size_kw = hash[:size_kw]
  @avg_energy_kwh = hash[:average_yearly_energy_produced_kwh]
  @size_class = hash[:size_class]

  # initialize class variables @@validator and @@schema
  @@validator ||= Validator.new
  @@schema ||= @@validator.schema

  # initialize @@logger
