California To Become First US State Mandating Solar On New Homes (ocregister.com)

OCRegister reports that "The California Energy Commission is scheduled to vote Wednesday, May 9, on new energy standards mandating most new homes have solar panels starting in 2020." From the report: Just 15 percent to 20 percent of new single-family homes built include solar, according to Bob Raymer, technical director for the California Building Industry Association. The proposed new rules would deviate slightly from another much-heralded objective: Requiring all new homes be "net-zero," meaning they would produce enough solar power to offset all electricity and natural gas consumed over the course of a year. New thinking has made that goal obsolete, state officials say. True "zero-net-energy" homes still rely on the electric power grid at night, they explained, a time when more generating plants come online using fossil fuels to generate power. In addition to widespread adoption of solar power, the new provisions include a push to increase battery storage and increase reliance on electricity over natural gas.

      Solar PV Cells degrade over time expected life 20 years

      No, Solar panels have a derating over 25 years.

      They continue functioning just fine, but with a reduced power output.

      A typical solar installation will cost about $25 per kwH per month. at $0.10 per kwH, that is the equivalent of about 20 years repayment time assuming two things: 1st, the cost of electricity does not go up over that 20 years, and 2nd, there is no subsidy on the cost of the panels.

      The panels themselves will still produce 70% of their rated power after 30 years, so at some point around the 30 years mark it becomes financially beneficial to replace old solar cells, but make no mistake, over the actual life of a home, it will be cheaper to put new panels on the roof every 30 years, than it will be to pay for electricity for those 30 years, and that is assuming no government subsidies for solar power at all.

      At the rate that panels are reducing in cost, and the cost of energy is rising, the subsidies for solar will be completely unnecessary in less than 10 years, maybe even as short as 5 years.

    In this pathological social construct we call civilization the rich elite have convinced the masses that by removing a person's inherent ability to construct a house for themselves and ensuring a monopoly for the construction companies they are somehow protecting people.

    What? I can only conclude one of two things from the tone of your post:

    Option A, you have never actually tried to build your own home and so have no idea what the process actually entails

    Option B, You actually tried to build your own home, but your own ineptness caused you to fail so miserably that the local building department put a stop to you, probably saving your life in the process.

    I have built 1 house completely from scratch, and renovated almost a dozen others in the course of my life. I am not a builder by trade (Software engineer currently). I do not have any professional certifications or licenses in the building trades, and I live in NY state, second only to California when it comes to building regulations. In spite of that, I have never had undue trouble with the building department or the building inspector. On the very first house, I did have to hire an architectural engineer to draft the plans for the renovation I wanted. They didn't know me from adam, and they wanted some assurance that the walls I was planning to move weren't just going to fall over. All of my other work was very straight forward. I did all of the plumbing and electrical myself. The inspectors all came through and sometimes asked for some changes for relatively minor things, but never made me take anything out or completely redo anything. Truth be told, the most trouble I ever had was with a lineman from the electric utility. He didn't like the electrical entry I had planned, and was of the opinion that it did not meet code in spite of the requisite signatures from the building inspector. I had to spend about 2 days playing phone tag with the chief building inspector and the utility supervisor before the whole thing finally got straightened out.

    If you want to get along with your local building department, seek them out before you start work on anything, and be sure to do your homework as far as what regulations apply so that you can have plans in place to address them appropriately. The first time you deal with them, expect to have to pay somewhat extra for certain engineering related costs, but once they know you, and trust you are not a nitwit, they will start working with you to help you save money on the things you don't need. If you go in with a combative attitude in the first place, you can expect the most miserable and expensive process imaginable, and you will deserve every minute of the pain you get for being a douche.

    Why do you suppose that is? Is there not enough room for housing in California? What makes California so different from other states that housing is so expensive?

    The reality is scarce availability is a direct result of out of control NIBYism implemented by those with power over the states regulatory regime. This solar thing is just one more drop in California's massive over-regulation bucket that is hurting real people in order to protect those with money/power by erecting even more barriers.

    One need only look at the epidemic of "illegal" additions where single family dwellings are being converted into mini-apartments and the growing homelessness epidemic (Home to 1/4th of the countries homeless population) to see that California's legitimacy has been eroded by insane racist policies that disproportionately disadvantage the poor.

    Since when has decentralized generation ever amounted to anything other than inefficient token gestures? Has always been the case much better results and higher efficiency are realized with large scale industrial production. Edison lost this fight a century ago.

    It would be better policy and more environmentally sound simply to levy some kind of tax on power consumption to support large scale solar projects vs piecemeal rooftop installations operating at low efficiency power conversion that won't be professionally maintained or tracked. It isn't like there is no space in California for solar farms. Mojave desert by itself has more than enough land area to supply the energy needs of the entire country.

    Agreed. In addition, about half the cost of rooftop solar is the installation, which should be significantly cheaper if it is done as part of the construction.

    Also, the cost issue is bogus. The FHA is offering 3% down mortgages to first time buyers, at less than 6% APR, and the cost of solar can be part of the mortgage. Since solar in California (where power costs are high, and sunshine is plentiful) has an ROI of about 8%, this means the house with solar has LOWER monthly payments than the same house without.

    You are dismissing an entirely valid line of thinking. In this specific case, the real goal is to make houses energy efficient, or carbon-neutral, or something like that. There's many ways to do that other than solar panels. Maybe someone wants to use a geothermal energy system, or a wind turbine. Or maybe they don't want to connect to the grid at all. Maybe they want to use a passive cooling design and a green roof. Often times regulations that tell people *how* to solve the problem are really corporations trying to use the regulations to steer people toward their products. Like requiring a particular safety valve, that only one company has a patent on. This prevents other companies from innovating by developing similar products.

    This has not always to do with HOAs. There are also historical districts that set strict rules. Most codes are more practical in nature, such as how many windows a house can have. That matters for fire safety especially in densely built neighborhoods.Or the pipe coming from a sump pump, it is usually not allowed to be connected to the sewer line, but has to dump outside and away from structures. That is to protect the sewer system during a rain storm. There are other codes such as no longer allowing aluminium, iron, or knob and tube cabling, no lead water or drain pipes, have cabling in conduits up to 30 ft high, working smoke alarms in multi-unit dwellings.... That all costs money, not only for new construction, but also for remodels. Those rules exist for a reason. Adding solar panels will increase cost, but there is a general benefit to the community. The lack of affordable housing has many other reasons, mainly that municipalities shy away from being landlords and that those who already live in an area are typically strongly opposed to have any affordable housing in their area. Administrators and politicians deciding otherwise tend to be looking for a new job soon after. Companies are not bound to turn a big profit on affordable housing either. The housing crisis is not due to cost, but because we as a society don't want low income households next door. Once that attitude changes and profit maximization is not the core focus, the issue can be resolved in rather short time.

    I'm not familiar with CA building codes, but I wonder which requirements they have for insulation. Preventing from heat to come into the house will significantly lower the power consumption for cooling and thus lower the power needs of households...which, by the way, are on average three times higher in the US than in Europe.
