For a spacious 5 bedroom house, an adequately sized solar array is crucial to powering all electrical needs including EV charging. Most homes this size require between 15 to 27 panels for full solar capabilities. But the ideal number depends on roof space, panel wattage, electric usage and EV charging needs.
Careful load calculations must factor in total kWh used for lights, appliances, heating/cooling and vehicle charging. While gas appliances and efficient lighting help minimize usage, large houses still have high demand. EVs add substantial charging loads. Collections of panels are then sized to meet total energy requirements.
Standard residential panels today output anywhere from 250 to 400 watts. Higher capacity panels mean needing less of them. But available roof space is also key. South-facing sections of the roof with full sun exposure all day are ideal panel locations.
Also consider future energy needs. A growing family may add more appliances and vehicles requiring more power. Oversizing a system slightly builds in buffer capacity. Inverters and wiring should support additional panels in the future.
For a large 5 bedroom home, a good starting estimate is around 20 solar panels. Depending on the home, this may range from 15 to 27. Using higher output 350-watt panels reduces the total number required. We recommend getting quotes for multiple panel quantities to find the ideal system size.

With robust capacity, a properly sized array can completely offset electric bills while powering daily EV charging. Careful system design maximizes solar energy usage before pulling from the grid. This saves households substantial money while reducing environmental impact.
In addition to the panels, adequate supporting equipment such as inverters, racking and wiring are vital for large installs. A seasoned solar contractor will include all required components for a complete, high-performance system. Minimal roof penetrations also preserve structural integrity.
For maximum savings, households can even consider pairing solar with a home battery. Stored solar energy powers the home and EVs when the sun isn’t shining. Batteries also provide backup electricity during grid outages.
In summary, installing 15 to 27 solar panels is recommended for large 5 bedroom homes needing ample power. Careful solar design and quality equipment ensure a system that meets all electric needs, including multiple EVs, for optimal energy independence.
