How Does Solar Work?

Solar energy is tricky business – but you have the best team on your side to get everything just right. Explore the image here to understand the role that each piece plays.

HowSolarWorks Panels — Centauri Systems

Solar Panels turn sunlight to DC energy

An electrical field is created when sunlight hits the solar panels. The product is direct current (DC) electricity which is not used by most homes and appliances.

HowSolarWorks Inverter — Centauri Systems

Micro-inverters convert DC to AC

Electricity flows to the micro inverters that are installed on the roof under the solar panels. Here the DC (direct current) electricity is converted to AC (alternating current) that homes and business use.

HowSolarWorks InverterToEnvoy — Centauri Systems

Enphase Envoy sends energy to your home or the grid

The envoy box decides when to send power to your home to power your lights and gadgets. If there is no demand for energy in your home, it will be sent to the grid and credited to your utility account.

HowSolarWorks Meter — Centauri Systems

Electrical meter records energy moving to and from the grid

The AC electricity travels through the meter to the main electric panel, which then delivers electricity throughout your home.

HowSolarWorks Battery — Centauri Systems

Solar energy charges batteries to be used as you decide

Batteries store the extra energy your panels produce during the day. This stored energy powers your home when the sun isn’t shining, like at night or on cloudy days. Batteries also provide backup power during outages, keeping essential appliances running and adding resilience to your solar system, without a backup system you will not have power during grid outages.

HowSolarWorks GridToMeter — Centauri Systems

Use what you need, send the rest to the grid

Power your home with clean solar energy as it is produced. Any unused electricity will flow back through your meter, creating a credit on your utility bill. During times of low or no production, you will still be able to pull electricity from the grid.

Solar Power is a Smart Investment

Owning solar gives you immediate and lasting financial benefits, greater energy security, and independence, breaking free from ever-rising payments to your local utility monopoly.

Energy Cost Increase Graph — Centauri Systems

Protect Yourself from Rising Energy Costs

Solar locks in energy savings and shields you from skyrocketing utility rates. If the trend continues as it has for 25+ years energy prices will only continue to increase.

Take Control with Energy Ownership

Stop renting your power—solar gives you equity, predictability, and independence.

Boost Your Home's Value and Marketability

Solar systems make homes sell faster and for more, while building long-term equity. Check out ths article for more on how solar panels increase home values.

GridOutages 1 e — Centauri Systems

Secure Your Energy Future Amid an Aging Grid

Solar ensures reliability and protection from potential grid failures or price increases.

Invest in Clean Energy Before Costs Rise Even More

Take advantage of current 2025 policies and incentives before potential tariffs or legislative changes increase costs.

Solar Power to Protect Our Planet

By switching to solar energy, homeowners can significantly reduce their carbon footprint, combat climate change, and contribute to a cleaner, greener future.

Cleaner Air and Water for Healthier Communities

Solar energy reduces harmful pollutants, protecting the air we breathe and the water we drink.

Combat Climate Change with Renewable Energy

Lower greenhouse gas emissions by switching to a sustainable energy source like solar.

SolarForThePlanet — Centauri Systems

Preserve Finite Resources for a Greener Future

Solar’s reliance on the sun reduces the strain on nonrenewable resources like coal and gas.

Build a Sustainable Legacy for Future Generations

Choosing solar ensures a healthier, cleaner planet for those who come after us.

What Is Net Metering?

Net metering allows homeowners to earn credits on their utility bills when their solar panels produce more electricity than they use, causing the utility meter to run backward during the day. These credits can offset electricity costs at night or when solar production is low.

4 Most Important Factors

when choosing a solar installer

Solar Installer Decision Factors

Product Quality & Technology

Not all solar panels are created equal. Understanding the products being offered is crucial for long-term satisfaction and performance.

  • Panel Efficiency: Higher efficiency panels produce more power in less space
  • Panel Grade: Tier 1 manufacturers offer better reliability and warranties
  • Inverter Quality: String, micro, or power optimizer systems each have advantages
  • Mounting System: Quality racking ensures proper ventilation and durability
  • Component Matching: Properly sized systems maximize efficiency and savings

      Why Racking Matters

      A good racking system should:

      • Secure your panels for 30+ years
      • Be built to withstand wind, snow, and storms
      • Have fewer attachments = fewer roof penetrations
      • Support long-term warranties and protection
      • Prevent costly repairs down the road
