Why You Should Overbuild Rooftop Solar for Future Needs

Are you considering installing solar panels on your roof? While sizing your system to match your current electricity usage is common, there are compelling reasons to think bigger.

Overbuilding your rooftop solar array can set you up for significant energy and cost savings as your needs evolve. This is especially true since Distribution charges increase and the cost of getting electricity to your home is worse every year.

Let's explore why going larger now can pay off in the long run.

‍

Anticipating Increased Electricity Demand

As we transition to cleaner energy solutions, many homeowners are making the switch to all-electric appliances and vehicles.

This shift can substantially increase your household electricity consumption.

By overbuilding your solar system now, you'll be prepared for these future energy needs without requiring costly system expansions later.

‍

Accommodating Efficient Heat Pumps

Heat pumps are becoming increasingly popular for their energy efficiency in both heating and cooling. However, they do require electricity to operate.

An oversized solar array ensures you have the capacity to power a heat pump system, potentially eliminating your reliance on fossil fuels for home climate control.

‍

Powering Electric Vehicles

Electric vehicles (EVs) are the future of transportation. Charging an EV at home can significantly increase your electricity usage.

With an overbuilt solar system, you can power your car with clean, renewable energy, further reducing your carbon footprint and fuel costs.

‍

Integrating Home Battery Storage

Home battery systems are becoming more affordable and popular, as evidenced by 50% of solar installations attaching a home battery in California.

An oversized solar array allows you to maximize the benefits of battery storage by ensuring you have excess energy to store for use during nighttime or cloudy days.

Economic Benefits of Overbuilding

Maximizing Available Roof Space

If you have the roof space, it makes economic sense to use it. The marginal cost of adding extra panels during the initial installation is often lower than installing a separate system later.

‍

Taking Advantage of Current Incentives

Solar incentives and tax credits may change over time. By installing a larger system now, you can potentially benefit from more favorable incentives that may not be available in the future.

The current incentive from the IRA is a 30% tax credit.

Hedging Against Rising Electricity Rates

As utility rates continue to rise, an overbuilt solar system provides a hedge against these increases. The extra energy you produce now could become increasingly valuable as electricity costs climb.

In terms of Net Metering, policies around the US are shifting. In some states like California, there's so much daytime solar pushed to the grid that the utilities cannot compensate homes and businesses with 1:1 credits any longer.

The new model of NEM 3.0 pays homes and businesses much, much less. This creates a different economic outlook for installing solar. Because of this, consumers are installing batteries to take advantage of time-of-use arbitrage (storing solar energy from the daytime and selling at night when electricity is more expensive).

If you overbuild your solar, you'll have more cheap electricity to power your life and may be able to pay your system off in as little as 4 years!

Considerations When Overbuilding

While overbuilding your solar system offers numerous benefits, it's essential to consider a few factors:

1. Check Local Regulations: Some utilities or municipalities may have restrictions on system sizes or net metering policies.
2. Assess Your Roof's Capacity: Ensure your roof can structurally support additional panels.
3. Evaluate Your Long-Term Plans: Consider how long you plan to stay in your current home and your future energy needs.
4. Consult with Solar Experts: Work with reputable solar installers to design a system that balances your current and future needs with local regulations and technical constraints.

Conclusion

Overbuilding your rooftop solar system is a forward-thinking strategy that can yield significant benefits.

By anticipating future energy needs, you can save money, increase your energy independence, and contribute to a cleaner environment.

As you plan your solar installation, consider the advantages of going bigger – your future self may thank you for the foresight.
