How to Optimize Your Solar Savings

Whether you're considering going solar or already enjoying the benefits of a Sunrun system, there are several ways to maximize your energy savings and strengthen your environmental impact. Here's how you can ensure you're making the most out of your solar investment.

1. Monitor your energy usage:

Keeping track of your energy consumption is crucial, especially after installing solar panels. As the #1 residential solar company, we commonly see that homeowners increase their energy usage after going solar. 

If you already have a Sunrun solar system (with a Powerwall, Shift or CT Clamp installed), you can easily monitor your usage through the Sunrun app. 

2. Use your appliances wisely:

Timing when you use your appliances can lead to significant savings, especially during peak energy cost hours from 4-9 PM. Here are some examples of high-energy appliances and how to efficiently use them: 

Air conditioning:
Best: Pre-cool your home up to 6-7 degrees before 4 PM, then use fans or open windows.
OK: Keep the AC on a higher setting until 9 PM after pre-cooling.
Avoid: Running the AC from 4-9 PM.

EV Charging:
Best: Charge mid-day when energy demand is lower.
OK: Charge after 9 PM.
Avoid: Charging during peak hours (4-9 PM).

3. Make energy-efficient upgrades:

Consider making energy-efficient upgrades to your home to complement your solar system. This could include installing energy-efficient appliances, improving insulation, or updating lighting systems.

4. Plan for seasonality:

Understanding and planning for the seasonal variations in solar production can help you manage energy use more effectively throughout the year. Here are some tips:

Summer 

• Increased home cooling needs (A/C usage) can offset savings, potentially leading to higher bills.

• Peak solar production occurs due to long daylight hours and direct sun exposure. Homes with net metering may build up credits during sunny days to offset future usage.

Winter

• Shorter days and lower sun angles reduce solar energy production. Increased heating usage may lead to higher electricity bills, especially if heating systems are electric. 

• Homes with battery storage or net metering can benefit from stored energy or previous credits to offset costs.

Summer/Fall

• Lower energy usage in mild weather can result in surplus energy being sent back to the grid, reducing bills or building energy credits.

By monitoring your energy use, managing appliance timings, making home efficiency upgrades, and understanding seasonal solar changes, you can significantly increase your savings and reduce your carbon footprint with Sunrun.
