Part 1: The Growing Market of Solar for New Construction
1. California’s Title 24, mandating solar on all
new homes in the state starting in 2020
a. Similar requirements for
commercial buildings possible in
coming years
2. Similar policies, for residential and
commercial buildings, emerging across U.S.
3. Other countries have also mandated solar
on new construction (France, Spain,
Bahrain)
This market is poised to grow due to a variety of factors
In Context: Why Solar for New Construction Is Increasingly Important
● May 2018: California became first state to
mandate solar PV systems on all new
homes
○ Official approval December 2018
● Applies to all low-rise single-family and
multi-family housing (three stories or fewer)
● Requirements take effect January 1, 2020
(buildings permitted before then are
exempt)
California’s Title 24: Solar Required on All New California Homes Starting in 2020
● Estimated to create 800 MW of new
residential PV demand from 2020-2023 (Wood Mackenzie Power & Renewables Solar
Market Insight Report 2018 Q2)
● Expected to account for the majority of
growth in the state’s residential market
● By 2023, solar for new homes is expected to
account for 20% of residential installed
capacity
How large will the new construction market be?
Expansion of California’s Solar Market
● Watertown, MA—solar required on all new commercial buildings 10,000 sq. ft. and up,
and new residential buildings of 10 units or more
● South Miami, FL—new homes required to have 2.75 kW solar for every 1,000 sq. ft.
● Tucson, AZ—new homes and duplexes must either have PV installed or be “solar
ready”
A number of other similar policies have been adopted across the U.S.
Not Just California, Not Just Residential
France
Beyond the U.S. similar measures have been adopted in several other countries
Not Just California, Not Just Residential
Spain Bahrain

Part 2: What Are the Challenges of Designing Solar for New Buildings?
h t t p s : / / w w w . a u r o r a s o l a r . c o m /
To Serve the New Construction Market, Solar Contractors Must Adapt
Designing solar for new buildings differs from traditional PV design in several key ways
Determining system size & placement
Analyzing shading & estimating production
Forecasting building energy consumption
Visualizing the design for clients
1. Determining How Many Panels Will Fit and Where to Place Them
When traditional approaches like onsite measurements and satellite imagery aren’t viable, as is the case when the building is not yet constructed, new options are needed

2. Assessing Shading and Irradiance Values, Forecasting Production
Shading analysis, and therefore production forecasting, is complicated by the lack of existing building
3. Forecasting Load Without Historical Data
Without historical energy consumption data, new tools are needed to estimate energy consumption

4. Showing the Client What the PV Design Will Look Like
New options are needed to create compelling visuals for the client for sales purposes
