In addition to solar, the proposed energy rules would require additional improvements to insulation in the walls and attics of new homes as well as more efficient windows, water heaters and other appliances.
She noted in an interview that deploying solar as part of the home building process will normalize the technology for tens of thousands of families, in a positive way.
As it is, it's going to be incredibly expensive and hard to overhaul the energy system, so researchers stress that it's crucial to follow the most cost-effective paths possible (see: "At this rate, it's going to take almost 400 years to transform the energy system").
McAllister said he believed the solar industry is now mature enough and ready for the mandate.
The average cost of constructing a single-family house was estimated to go up by $10,538 - although solar contractors in the San Diego area put the costs of a solar installation at about $20,000, depending on the size of the home.
The CEC estimates the move will reduce greenhouse gas emissions by 700,000 metric tons over the course of three years. It painted the solar requirement as a major step toward lowering utility bills and ridding California of "gas-guzzling homes". Alameda County is also considering a solar requirement. In the alternative, a homebuilder told the Orange County Register that the additional costs in play would make homes less affordable for many buyers. "Adding more things to the cost is probably not a good thing".More news: Justin Thomas can join rare company with Jack Nicklaus this week
Residential solar system. Author: mjmonty. Meanwhile, non-residential dwellings will achieve energy savings of 30%, the Energy Commission estimates. "This solar decision could be yet another win for America's energy independence". "California is way ahead of the curve", said Gudell.
Solar panels, said Redfin agent Kalena Masching, are "rarely on anyone's list".
Although unprecedented in many ways, the solar panel requirement will be incremental.
Borenstein notes these savings are effectively subsidized by other ratepayers without solar panels, net metering and solar tax credits.
Anne Hoskins, chief policy officer for solar provider Sunrun, said transfers of leases should not be an impediment to home sales.
Utilities uniformly applauded the commission's solar rules which were 12 years in the making.
The California Building Industry Association, which represents new homebuilders, has expressed reservations about the new rules, saying it wished the state would have postponed the regulations for two years. "The best form of marketing".
