How to Make New Buildings Truly "Solar Ready"

Going further than the state-mandated requirements can save you cost and effort down the road.

by Sage Renewable Energy Consulting


Since 2013, the State of California has mandated that all new renovation and construction be “solar-ready.” According to their guidelines, buildings designed to be “solar ready” can install solar faster, with less complexity, and at lower cost to complete.   

Here's a primer on Title 24 of the California Energy Code.

But simply complying with the minimum requirements for “solar-ready” buildings is not the same as having a comprehensive, forward-thinking energy plan to meet financial and environmental goals. It’s important that your architects look at your project holistically, with options for solar, energy efficiency, energy storage and electric vehicle charging in mind. This small, up-front investment in energy planning will pay for itself and make the process easier when you commit to clean energy.

A few simple measures you can recommend to your architect can reduce the uncertainty, cost and complexity of implementing energy solutions throughout the life of your new project:  

Flat roofs require additional weight to ballast the PV system.

1 - Include a solar PV system in the structural design of the building.

2 - Reduce roof parapet heights and make as few roof penetrations as possible to maximize the available space for solar panels. 

3 - Where possible, use sloped metal roofing for easy installation and no roof replacements over the 25-year life of the system. 

4 - For flat roofs, plan for additional weight for ballasted PV systems.

Design parking lots to accommodate solar shade canopies.

5 - Design parking lots for solar shade structures: south-facing, double-rowed, with perpendicular (not slanted) stalls.

6 - Make sure to plant low vegetation in and around future parking canopy areas, and plan for under canopy lighting in parking lots.

7 - Leave space for energy storage and electric vehicle charging stations.
