The great solar debate

The Great Solar Debate: String vs. Microinverters: Making the Right Choice for Your Solar System

When planning your solar installation, choosing the right inverter technology is crucial. The inverter serves as the heart of your solar system, converting DC electricity from your panels into AC power that your home can use. Let's dive into the two main types of inverters and help you make an informed decision.

Understanding Solar Inverters: The Basics

Before comparing options, let's understand what inverters do:

  • Convert DC (direct current) from solar panels
  • Transform it into AC (alternating current) for home use
  • Enable grid connection and power management

The Basics

String Inverters: The Centralized Solution

What Is a String Inverter?

A string inverter is a centralized unit typically installed on the side of your house or in your garage. It handles the power conversion for multiple panels connected in series (strings).

Important Note: All hybrid inverters (like SolarEdge, EG4, and Tesla Powerwall 3) are string inverters, but not all string inverters are hybrids.

Advantages of String Inverters

  1. Cost-Effectiveness
    • Generally less expensive than microinverters
    • Better budget option for larger systems
    • Lower component count
  2. Simple Installation and Service
    • Fewer components to install
    • Ground-level access for maintenance
    • Easier troubleshooting
  3. Future Expansion
    • Easily add more panels (within capacity limits)
    • More battery integration options
    • Flexible DC and AC coupling choices

Disadvantages of String Inverters

  1. Reduced Efficiency in Heavy Shade
    • May need power optimizers for heavily shaded installations
    • Best performance in full sun conditions
  2. Single Point of Failure
    • System-wide downtime if inverter fails
    • Requires prompt repair/replacement
  3. Limited Panel Monitoring
    • Basic string-level monitoring
    • Individual panel monitoring requires additional hardware

Microinverters: The Distributed Approach

What Are Microinverters?

Small inverters attached to each individual solar panel, converting DC to AC at the panel level.

Advantages of Microinverters

  1. Improved Shade Tolerance
    • About 3% improvement in significant shading conditions
    • Individual panel operation
    • No string effect
  2. Panel-Level Monitoring
    • Detailed performance data
    • Easy problem identification
    • Quick troubleshooting
  3. Minimized Downtime
    • Single panel failures don't affect others
    • Distributed risk
    • Continuous system operation

Disadvantages of Microinverters

  1. Higher Initial Cost
    • More expensive per watt
    • Multiple units required
    • Higher component count
  2. Maintenance Considerations
    • Roof access required for repairs
    • Higher labor costs for service
    • More components to potentially fail
  3. Limited Scalability
    • Potential compatibility issues with future upgrades
    • Limited battery integration options
    • AC-coupled battery systems only

Making Your Decision

Consider these factors when choosing:

System Size

  • Under 10kW: Microinverters might be cost-competitive
  • Over 10-15kW: String inverters often more economical
  • 20kW+: String inverters typically best choice

Installation Location

  • Heavy Shade: Consider microinverters or string + optimizers
  • Full Sun: String inverters work well
  • Ground Mounts: String inverters ideal

Future Plans

  • Battery Addition: String inverters offer more options
  • System Expansion: Consider future compatibility
  • Monitoring Needs: Evaluate required detail level

The Battery Factor

An important consideration often overlooked: when adding battery storage, the "single point of failure" argument against string inverters becomes less relevant. Why? Because all battery systems require additional components (transfer switches, gateways, combiners) that create their own potential failure points.

Debunking Common Myths

The "Christmas Light Effect" myth (one shaded panel affects all panels) is outdated. Modern string inverters with bypass diodes handle partial shading effectively. Don't let this old misconception drive your decision.

Conclusion

The best choice depends on your specific situation:

Choose String Inverters If:

  • Installing a larger system (10kW+)
  • Planning future battery addition
  • Working with minimal shading
  • Prioritizing cost-effectiveness
  • Installing ground mount system

Choose Microinverters If:

  • Installing a smaller system
  • Dealing with significant shade
  • Requiring detailed panel monitoring
  • Prioritizing maximum energy harvest
  • Working with multiple roof orientations

Remember: Consult with qualified installers and consider your specific needs before making a final decision.

Everyone gets this wrong

You have no idea how often I get a call from one of my customers who is confused about their solar billing. I mean the day I recorded this video I had 2 calls with homeowners and we were going over the bill after solar and their solar production. I decided its time to get this video out there! I do hope the title will be easy enough for those who are looking for guidance to find it, if it was not, do share what you think the title should be??? I guarantee you there are so many people out there who are not my clients who have no idea how to properly understand how their system works. You are promised this amazing dream of your bill offsetting your usage and a zero-dollar bill and then.... the bubble bursts. You get a high electric bill and you wonder if your system is even working... you do not trust the utility company and if they are actually paying you for all that you sell to them... and no wonder you dont get this...

YOU DONT KNOW WHAT YOU DONT KNOW! So let's go over 2 of my electric bills! Let's review how all of this works and hopefully help you verify if your solar system is broken... if something is not working properly!

PLEASE let me know in the comments if my explanation made sense to you and if it was helpful!

THANK YOU SO MUCH FOR BEING HERE!!! If you are looking to install a solar system for your home, I truly hope that my videos will become a guide for you. You can also reach out to me for help or a quote ( I only install in DFW, but do consultations and quotes review if you are not in DFW!).

Understanding Your Solar Electric Bill: A Complete Guide

Have you recently installed solar panels and found yourself confused by your electric bill? You're not alone. Many homeowners look at their first post-solar bill and think, "This can't be right!" Today, let's decode the mystery of solar billing and help you understand exactly what those numbers mean.

The Basics: Your Two Power Sources

When you go solar while staying connected to the grid (which most people do), you have two sources of power:

  1. Your solar system
  2. The utility company

Most homeowners choose to stay grid-tied because going off-grid is extremely expensive. Plus, having the utility as a backup power source for nights and rainy days is both important and cost-effective.

How Solar Power Flows

Here's what happens with your solar power:

  1. Solar panels generate electricity on your roof
  2. The inverter converts DC power to usable AC power
  3. This power FIRST feeds your home
  4. Only excess power goes back to the grid

The Crucial Part Many Miss

 The Crucial Part Many Miss

Here's the key point that often confuses homeowners: The meter only shows excess power that wasn't used by your home. Let's break this down with an example:

If your solar system generates 20 kWh in a day:

  • Your home directly uses 12 kWh
  • The remaining 8 kWh goes to the grid
  • At night, you might need 5 kWh from the grid
  • Total daily consumption = 17 kWh (12 from solar + 5 from grid)

Reading Your Bill

Your utility bill will show two main figures:

  1. Charges (or "delivered" power) - What you bought from the utility
  2. Credits - What you sold back to the grid

Pro Tip

Request your utility provider to change your billing cycle from the first to the last of the month. This makes calculations much easier!

Real-World Example

Let's look at two billing cycles from my personal solar system:

Spring (March-April)

  • Total Solar Production: 1,268 kWh
  • Sold to Utility: 911 kWh
  • Direct Solar Usage: 357 kWh (1,268 - 911)
  • Bought from Utility: 392 kWh
  • Total Home Usage: 749 kWh (357 + 392)

Summer (July)

  • Total Solar Production: 1,161 kWh
  • Sold to Utility: 394 kWh
  • Direct Solar Usage: 767 kWh (1,161 - 394)
  • Bought from Utility: 1,082 kWh
  • Total Home Usage: 1,849 kWh (767 + 1,082)

Tips for Maximizing Your Solar Benefits

To get the most from your solar system:

  • Use more power during daylight hours
  • Run appliances like washing machines and dishwashers during peak sun
  • Start cooling your home before sunset
  • Charge EVs during solar production hours

Monitoring Your System 

Modern Systems

Many newer systems come with CT (Current Transformer) monitoring, which measures power flow automatically.

Older Systems

For older systems without monitoring, you can add third-party options like:

  • Solar Sense
  • Emporia monitoring device These cost less than $200 and can provide valuable usage data.

The Bottom Line

Remember: Your utility bill only shows what you exchange with the grid - what you buy from them and what you sell to them. It doesn't show your total solar production or home consumption. Understanding this distinction is key to making sense of your solar investment.

The Bottom Line

How to Check if Your System is Working Properly

Compare the same months year over year:

  • Check total production
  • Compare grid purchases
  • Look at excess solar sold
  • Consider usage changes (new appliances, more people at home, etc.)

This way, you can spot any significant changes that might indicate a problem with your solar system.

Note: This guide covers grid-tied systems without batteries. Stay tuned for our upcoming guide on systems with battery storage!

Need More Help?

If you're still unsure about your solar billing, start by:

  1. Downloading your solar production data
  2. Gathering your utility bills
  3. Comparing the numbers using the formulas above
  4. Reaching out to your installer if something doesn't add up

Remember, understanding these numbers helps you maximize your solar investment and ensure your system is working as intended.
