Yan zhao door in 2020, household photovoltaic become residential 'mandatory' standard of California!

According to the requirement of the California 2019 building energy efficiency standards, since January 1, 2020, all in California to build new homes include three floors below single-family or apartment will be required to install residential pv system. The regulation is the California energy commission new part of building energy efficiency standards in 2019, aiming to reduce greenhouse gas emissions.

rules and regulations, if the house covered with trees and other buildings or roof is too small and cannot build photovoltaic components, can apply for a waiver or furnish make use of the energy storage system for energy saving. In addition to increasing photovoltaic modules, the new California home also must conform to the latest insulation standards. In addition, still need to be able to minimize the ventilation system of outdoor and indoor air pollution.

according to TestPV statistics, every year new 7 in California. 5 - 8. About 1 00000 homes. 50000 will be installed with photovoltaic (pv), old house with 10 every year. 50000 homes using photovoltaic (pv). Since 2020, California new housing households with photovoltaic (pv) from 1 every year. 50000 soared to 80000.

for every new residential pv installations, standard requirements: home solar system must & other; Appropriate size & throughout; , solar energy, based on the area of the building, room number and climate zones where cover housing use of electricity in a year. In this way, Not excessive installation) Adjust the system size, to keep more than reasonable system costs and reduce electricity on the Internet is very important.

according to the journal of the American academy of environmental research and policy center ', the analysis of household electricity use, general families need 9 kw photovoltaic system can meet the demand of the electricity consumption. Considering the general housing size, if installed per 4 - 6 kw to calculate, increase 260 - new residential California alone 400 mw photovoltaic demand, household photovoltaic installations of California market will usher in explosive eruption, aggregate demand will reach 600-2020 900MW。

and, more importantly, the national 100 cities announced the schedule, renewable energy to meet 100% of its energy needs, some of the city is already considering their own blueprint version of California. If California officially implemented and successful application of solar energy equipment, solar portal, the policy will soon spread to other states across the country.

according to the California energy commission, insist on building energy efficiency standards in 2019 will make the cost of building an ordinary bridal chamber increase about $9500, but in the next 30 years will reduce energy and maintenance costs $19000. In addition, the commission estimates, based on the 30-year mortgage, homeowners pay for ordinary housing about 40 dollars a month, but can save $80 a month of heating, cooling and lighting costs.

the California energy commission prepared 2019 building energy efficiency standard q&a, follow the manual the California 2019 households in the house, the 2019 residents of California and non-residential building energy efficiency standards.

California, estimated that solar power network, in the next 10 years, suitable for most family homes and many commercial buildings solar new rules that would save hundreds of millions of dollars for California residents and enterprises of the energy costs. In the range of California single-family construction, only 15% at present 20% installed solar systems.
