Integrating Solar Power with Your HVAC System

Solar power and HVAC systems are natural partners. Your air conditioning represents one of your home's largest electricity consumers—perfect for offsetting with solar generation.

Why Solar + HVAC Works

Peak Alignment:

AC runs most during hot, sunny days

Solar panels produce most during same periods

Generation matches consumption naturally

Cost Savings:

Offset highest-cost electricity usage

Reduce or eliminate cooling costs

Potential for net-zero energy homes

System Sizing Considerations

Calculating HVAC Load:

Typical 3-ton AC: 3,000-3,500 watts

Running 8 hours daily in summer: 24-28 kWh

Monthly cooling: 720-840 kWh

Solar Panel Requirements:

Average California panel: 350-400 watts

Each panel produces ~1.5 kWh/day

Need 16-20 panels for cooling alone

Whole-Home Approach:

Most homeowners size solar for total electricity needs, not just HVAC. This provides year-round savings.

Maximizing the Synergy

Smart Scheduling:

Program your HVAC to pre-cool during peak solar production, reducing evening grid demand.

Battery Storage:

Store excess solar for evening AC use when panels aren't producing.

Efficient HVAC Equipment:

Higher efficiency equipment means smaller solar array needed.

Heat Pumps and Solar

Heat pumps are ideal solar partners:

Efficient cooling and heating from one system

Lower electricity consumption than resistance heating

Year-round use maximizes solar investment

Financial Considerations

Incentives:

Federal solar tax credit (30%)

California solar incentives (varies)

Net metering credits

HVAC efficiency rebates

Payback Period:

Combined solar + high-efficiency HVAC typically pays back in 6-10 years, with decades of savings after.

Bay Area Solar Potential

Our region enjoys excellent solar conditions:

250+ sunny days annually

High electricity rates maximize savings

Strong net metering programs

Mature solar installation market

Pairing solar with efficient HVAC is one of the smartest investments California homeowners can make.
