Without an inverter, your solar panels would not be able to power your home.

There are two main types of inverters that dominate the market today: string inverters and microinverters.

  • String inverters connect multiple solar panels together in a series and then send the power to a single inverter. While they are efficient and cost-effective, their performance can be compromised if even one panel is shaded or underperforming.

  • Microinverters are installed on each individual solar panel, optimizing the energy output from each panel separately. This design maximizes efficiency, especially when panels are affected by shading, dirt, or dust. The microinverter pros are numerous, as each panel operates independently, minimizing the risk of power loss.

In the Enphase vs Fronius debate, understanding these two types of inverters helps us appreciate why one might be a better fit than the other based on your home’s unique requirements.

How to Increase Solar Panel Efficiency: 10 Proven Ways to Maximize Output and Minimize Energy Loss

As energy prices rise and sustainability becomes a priority, knowing how to increase solar panel efficiency is no longer just a technical detail—it’s essential knowledge for any solar system owner. Whether you’re installing new panels or have had a system for years, improving efficiency helps you boost output, cut costs, and reduce energy loss over time.

In this comprehensive guide, you’ll discover 10 proven strategies that show you exactly how to increase solar panel efficiency—from proper installation techniques to maintenance tips and advanced upgrades. These techniques are applicable to residential rooftops, commercial installations, and even off-grid systems.

Let’s dive in and uncover how to get the most from every ray of sunshine hitting your panels.

Understand How Solar Panels Work

Before exploring how to increase solar panel efficiency, it’s important to understand the basics of how solar panels generate electricity. Solar panels contain photovoltaic (PV) cells that convert sunlight into direct current (DC) electricity. This is then converted into alternating current (AC) by an inverter, which powers your home.

However, not all sunlight that hits the panels is converted into electricity. A portion is lost due to:

  • Heat buildup

  • Electrical resistance in wiring

  • System design flaws

  • Dirty panels or shading

By identifying where these losses occur, you can take informed steps toward improving overall system performance and ensuring minimal energy loss.

Optimize Your Panel Angle for Maximum Exposure

Your panel angle significantly affects how much sunlight your system can capture throughout the day and across different seasons.

  • The ideal angle is generally equal to your location’s latitude. For example, in Brisbane, it’s around 27°, while in Melbourne, it’s about 37°.

  • A steep angle works better in winter, while a flatter angle captures more energy in summer.

  • Adjustable mounts can help you adapt throughout the year.

Correctly adjusting the panel angle is one of the simplest and most effective ways of how to increase solar panel efficiency across all conditions.

Clean Solar Panels to Prevent Build-Up

Dirt, dust, leaves, and bird droppings may seem harmless, but they can cause significant power loss over time. A thin layer of grime can block sunlight and reduce your system’s effectiveness.

  • Light dust may reduce output by up to 5%

  • Sticky substances like bird droppings can cause 15% or more energy loss

  • Industrial pollution or pollen buildup can cut efficiency by over 20%

Knowing how to properly clean solar panels is key. Use a soft brush with water—avoid abrasive tools and harsh chemicals. For hard-to-reach rooftops, consider professional solar cleaning services.

If you’re serious about learning how to increase solar panel efficiency, start by keeping those panels clean year-round.

Eliminate Shading on Panels

Even minimal shading—like from a tree branch or nearby building—can have a major impact on your panel’s performance. This is because most solar panel systems are wired in series, meaning one shaded cell can reduce the output of the entire array.

  • Regularly trim surrounding trees and remove obstructions

  • Consider installing microinverters or optimizers to reduce impact

  • Plan your system layout during installation to avoid future shading

Reducing shade is a powerful tactic if you’re trying to boost output and minimize energy loss, especially in urban areas with lots of potential obstructions.

Upgrade to High-Efficiency Solar Panels

Not all solar panels are created equal. Older or budget models typically offer 14–16% efficiency, while modern high-performance panels deliver up to 23% efficiency.

Brands like Trina, Jinko, and Risen—available through Esteem Energy—offer high-output monocrystalline panels that outperform older technologies.

By upgrading, you:

  • Maximize energy generation per square meter

  • Reduce overall system size for the same output

  • Improve performance in low-light or cloudy conditions

This is a long-term investment for homeowners wondering how to increase solar panel efficiency for the next 25 years or more.

Maintain Inverters and Electrical Connections

Your inverter plays a critical role in overall system performance. If it’s not functioning efficiently, even top-tier panels can underperform.

  • Check for warning lights or error messages on your inverter

  • Ensure cables and connectors are not corroded or loose

Can You Add Solar Panels to an Existing System? A Complete Homeowner’s Guide to Solar Expansion

If you’ve ever wondered, “Can you add solar panels to an existing system?”, the good news is that it’s absolutely possible! As energy demands grow or your current system proves insufficient, many homeowners are exploring solar system upgrades to increase their energy independence. Whether it’s for a new electric vehicle (EV) or to reduce ever-increasing electricity bills, expanding your existing solar system can be a smart choice.

In this guide, we’ll dive deep into the steps involved in adding panels to your system, what to consider during the process, the costs associated with system expansion, and much more. So, if you’re asking yourself, “Can you add solar panels to an existing system?”, let’s get you all the answers you need.

Why You Might Need to Add More Panels

There are many reasons why homeowners look into adding panels to their solar systems. These include:

  1. Lifestyle Changes: If you’ve recently purchased an electric vehicle (EV), added new appliances, or even begun using a solar battery, your energy demand may have grown beyond what your current solar setup can handle. System expansion allows you to adjust your solar capacity to meet these new needs.

  2. Rising Electricity Bills: If your energy bills are climbing and your existing system isn’t generating enough power to cover your household’s needs, adding panels can help you capture more sunlight and offset the rising costs of grid electricity.

  3. Undersized Original System: In some cases, when the initial solar system was installed, it may not have been sized appropriately for the home’s energy requirements. System expansion provides a simple way to upgrade the system without completely replacing it.

Is Your Existing System Compatible?

Before you proceed with adding panels to your existing solar system, it’s essential to determine if your current setup is compatible with the new additions. Here’s what to consider:

1. Inverter Limitations

The inverter in your system plays a critical role in converting the energy generated by your panels into usable electricity. However, not all inverters are capable of handling the added capacity of additional panels. To assess if your inverter is compatible with a solar system upgrade, you’ll need to check its size and efficiency. If the inverter cannot handle more panels, it may need to be replaced.

2. Age of the Original System

Older systems may have less efficient components that struggle to work optimally with newer, high-performance panels. Adding panels to an outdated system could also result in reduced energy production. You may want to consider upgrading your system’s components (such as the inverter and battery) when adding new panels.

3. Panel Brand/Model Matching

Solar panels are designed to work within a specific brand or model system. If your existing panels are from a different manufacturer than the new ones, they may not work efficiently together, leading to mismatched voltage and output. Always ensure that any new panels match the specifications of your existing setup for optimal performance.

4. String vs Microinverter Considerations

If your system uses string inverters, adding more panels may present a challenge. String inverters combine multiple panels into one group or “string” for energy conversion, which can reduce efficiency if the panels have different characteristics. However, microinverters, which allow each panel to operate independently, offer more flexibility when adding panels to an existing system.

Cost of Adding Panels to an Existing System

Expanding your solar system isn’t free, and the cost of adding panels depends on several factors. Let’s break down the typical expenses:

Average Cost-Per-Watt

The price per watt of solar panels can vary depending on the brand and efficiency of the panels. On average, you can expect to pay between $0.70 and $1.50 per watt for new panels. The cost of installation, including labor and additional equipment, can bring the total price up, but it’s still a cost-effective solution when you compare it to the long-term savings on electricity bills.

Additional Installation or Equipment Fees

Besides the cost of the panels themselves, there are additional fees to consider. These may include installation costs, inverter upgrades, wiring, and mounting systems for the new panels. Depending on the complexity of the installation and the components needed, these costs can range from $500 to $2,000 or more.

Government Incentives and Rebates

Many regions offer financial incentives, rebates, or tax credits for homeowners looking to expand their solar systems. For example, in some areas, adding panels may qualify you for local rebates or federal tax credits. Be sure to research any available incentives to help lower the cost of your solar system upgrade.

~2.4 kW

Benefits of Expanding Your Solar System

Expanding your solar system by adding panels can have significant long-term benefits. Here are just a few of the reasons why more homeowners are opting for system expansion:

  1. Increased Savings on Energy Bills: More panels mean more power generated by your solar system, reducing your reliance on grid electricity. This can lead to substantial savings on monthly energy bills.

  2. Battery Storage Compatibility: If you’re considering adding a solar battery in the future, expanding your solar system can help charge it more efficiently. The added panels will provide the necessary energy to store for later use.

  3. Future-Proofing Your Home’s Energy Needs: With energy demand continuing to rise, system expansion ensures your solar system is capable of handling future increases in electricity consumption. It also provides flexibility to power new technologies like EVs and home appliances.

Potential Challenges to Consider

While expanding your solar system can be beneficial, there are some potential challenges that homeowners should be aware of:
