California to require solar panels for new homes by 2020


On Wednesday, the California authorities adopted a paper that requires installing solar panels on the roofs of all new homes from 2020. Local experts believe that this measure will allow each family to save about $ 40 monthly on electricity and heating bills.

Local energy department approved the building norm on the mandatory installation of solar panels in all new homes in the US state of California since 2020. As it follows from the agency's statement, by this date all builders must necessarily switch to energy efficiency standards adopted in California in January (standards are recommendatory in nature for the time being).

The department believes that installation of such batteries in a state with an average of 146 days of sunshine a year will reduce greenhouse gas emissions equivalent to the amount emitted annually by 115,000 cars with an internal combustion engine.

According to the authorities, the amount of energy consumed from traditional sources will be reduced by 30% after the introduction of new energy efficiency standards only in the non-residential sector of the state.

It is predicted that for an apartment house, taken in a mortgage for 30 years, the mandatory installation of solar panels will add an average of $ 40 to the monthly payment for the house, but for electricity, heating and air conditioning, owners will pay monthly $ 80 less. Thus, the net savings will be $ 40 per month.

Under the new standards, batteries will be installed on all new residential and non-residential buildings, apartments and condominiums with a height of no more than three floors. The only exceptions are buildings that are located in the shade of trees or tall buildings. These cases require an assessment of appropriateness of a house, depending on its actual insolation. The adoption of the new rule was pleasant to environmental organizations but caused mixed reactions among developers. "I'm very disappointed," Ian Gill, managing partner of the local Silvergate Development company, said in an interview with The Sun Diego Union Tribune. He believes that the new rule will have a bad effect on home sales for the middle class. "These houses are sold here for $ 450-500 thousand, so an additional $ 10-20 thousand (for solar panels) will significantly reduce their availability for customers," - said the developer.

Economist of the American Enterprise Institute, James Pethokoukis, also expressed a similar point of view on the CNBC channel: "This is good for wealthy homeowners, but for everyone else this may a reason to refuse to go to California or leave it as soon as possible." At the same time, Director of the California Association for the Development of Solar Technology, Kelly Knutsen, believes that all categories of homeowners will benefit from the transition to new standards. "Less well-off families pay electricity and heating bills more proportionately (to their incomes) than others. Therefore, the installation of such panels will be a good investment for all residents of the state," the expert believes.
