An overview of the new California solar mandate

When comes to the solar generation power, there is no other state that can even think of beating California. California is the hub for solar power generations in United States. The second highest solar energy producer in the US is North Carolina which is having 4 times less installed capacity. California is the leading solar energy producer not because it is having abundance of sunshine, ya that’s also the reason but the main reason behind this is the California government policies that have made California achieve such heights in field of solar energy.

What is California solar mandate?

The California new solar mandate is a brand new building code introduced by the California Solar Initiatives (CSI) which says that all the new houses that is being constructed in California after January 1, 2020 will be having a solar photovoltaic (PV) system and this code will be applied to both the single and multiple family homes which are up to 3 stories high.

To meet the annual electricity usage of the building, the new solar panel system needs to be large enough. As determining the electricity usage of the newly constructed houses can be very difficult so, the builders are using an estimate for each and every property that is based on the house floor space and the weather around.

The California Solar Initiatives have provided some flexibility in terms of sizing the solar panels. The builders while constructing the building are allowed to decrease the size of the required solar panels by a margin of 25 percent. But it is only applicable if you are connecting your solar panel with any additional batteries inside the house and if you are doing it all right by connecting it into right battery then you are allowed up to 40 %.

Exceptions to the California solar mandate

The newly solar mandate introduced by the California Solar Initiatives has some exceptions with it as well. There are few types of house construction that have been excluded from the California solar mandate. The exemption works if your house roof is not enough big or strong to handle the Photovoltaic (PV) system then you can avoid installing that system without any problem. Or if your house is not getting proper sunshine throughout the season then also you can avoid installing the new Photovoltaic (PV) system on your roof.
