Solar Mandate In California Will Save 

California has a long lasting connection with the sun.   Many memorable moments have to do with the sun, and with California.  History is history,  and on May 9, 2018, antiquity was made yet again. The California Energy Commission collectively established the requirement that all new houses and low-rise apartments built from 2020 onwards incorporate solar panels. The approval was supported by builders, utilities, and solar manufacturers. Now, that is some super duper news! 

The establishment provided a model solar panel system. A photovoltaic solar roof installation of 3,015 watts with nine modules rated at 335 watts each will produce about 133,630 kWh ~(3.015)(365)(30)(4.7) / (1 + (0.5%)^(30)) over a period of 30 years. The cost of such a system is calculated at $3,381 ($1.12)(3,015). This indicates that the price per kilowatt will be $0.025 ($3,381 / 133,630). The daily energy generation was averaged throughout California with an annual solar panel degeneration of 0.5%, and it is measured to produce 12.2 kWh (133,630) / (30)(365) daily per roof. This is almost two-thirds of the daily electricity demand of an average California residence.

Typical Solar Price Per Watt

The average power price per kWh in California is $0.193. This indicates expected savings of $0.168 ($0.193 – $0.025) per kWh offered on-site or $22,410 ($0.168)(133,620) saved beyond 30 years at a fixed energy price. Moreover, it is expected that every installation will save $9,500 in power expenses per building over 30 years, which is in position with what we have discovered.

The monthly lease payments will add $24.81 per month to the cost of each building. This will add $8,931 ($24.81)(360) in contract expenses (principal and interest) to the building’s mortgage. It will save $62.25 per month in energy costs or $22,410 in energy cost savings over 30 years. The effect is a net savings of $37.44 per month or $13,479 after paying for the energy producing facilities.

The California Energy Commission estimates that 117,000 new single-family homes and 48,000 multi-family units will be built in 2020. I calculate that this will add almost 735 gigawatts of additional power in 2020. This is similar in capacity to two one gigawatt utility plants (735 / 365).

Solar Price Drop 

The reason that the cost is so low for the solar system discussed before is due to the expected system cost decreases by installing it at the time of construction. Supplementary savings are anticipated from a large number of installations. A survey of some of the reasons for this reduction in costs is discussed several articles around the internet. Nearly every division of expenses are expected to decrease with the new requirement.
