Guide to Solar Panel Maintenance (2024) 

How can I tell if my solar power system is performing well?

Here are some key ways to tell if your solar power system is performing well:

Monitor Production:

  • Solar Meter: Most solar systems come with a solar meter that tracks the total kilowatt-hours (kWh) your panels generate. This is the most crucial data point. Ideally, you should see the kWh number steadily increasing during daylight hours. If the kWh isn’t increasing or the increase is minimal, it might indicate a problem.
  • App Monitoring: Many solar providers offer apps to monitor your system’s performance remotely. These apps can provide detailed data on daily, weekly, monthly, or even yearly production.

Compare to Historical Data and Weather:

  • Track Trends: Keep track of your solar power generation over time. You can create a spreadsheet or use your monitoring app’s historical data function. Normally, your solar panels should produce a certain amount of electricity on sunny days. By checking your system’s monitoring data, you can compare how much power it’s generating right now to how much it made on sunny days in the past. If you see a big drop in power generation compared to those sunny days, it could mean there’s a problem with your panels.
  • Weather Impact: Solar panels naturally produce less energy on cloudy or rainy days. However, they still generate some power. If you notice a substantial drop in production that doesn’t correlate with bad weather, it’s a cause for investigation.

Physical Inspection:

  • Visual Check: Perform a periodic visual inspection of your solar panels. Look for any signs of physical damage, such as cracks, discoloration, or bird droppings that might be blocking sunlight.

Electric Bill:

  • Lower Bills: Solar panels are great because they can help you lower your electric bill. But if your electric bill hasn’t gone down much after using solar panels for a while, there might be something wrong with them. Just remember, how much electricity you use can change throughout the year, so that might affect your bill too.

Pay Attention to System Alerts:

  • Error Codes: Some solar panel boxes (inverters) have lights or even show error messages. If you see any red blinking lights or confusing messages, check your solar panel manual first. If that doesn’t help, call the company that installed your panels for advice.

Don’t Hesitate to Consult Your Solar Provider:

  • Professional Expertise: That’s a perfect and clear conclusion! It reminds the reader of the final step if they’ve gone through the troubleshooting tips and have lingering concerns. They’re the experts and can help you figure out what’s wrong and fix it.
  • To see how well your solar panels are working, you can check a few things:
    • Look at how much power they’re making now and compare it to sunny days in the past. See if your electric bill has gone down since you got solar panels (but remember, how much electricity you use can change throughout the year). Give your panels a quick look to see if anything looks broken or dirty. Check the box that converts solar power to your home power (inverter) for any flashing lights or error messages. By keeping an eye on these things, you’ll know if your solar panels are working their best.

What are solar panel soft costs?

  • Solar panel costs can be broken down into two main parts: hardware and soft costs. Hardware costs are the physical parts you can see, like the solar panels themselves, the wiring that connects them, and the mounting system that holds them in place. Soft costs are all the other expenses that go into getting your solar panels up and running, but they aren’t physical things. These can include things like:
    • Permits you need from the government to install solar panels
    • Designing your solar system to fit your roof and energy needs
    • The work of installing the panels
    • Inspections to make sure everything is safe and working properly
    • Financing your solar panel system (if you don’t pay for it all upfront) They encompass a variety of factors that contribute to the price you pay to go solar. Here’s a breakdown of what soft costs typically include:
  • Permitting and Inspections: Permits. Local hassle. Fees. Waiting. Get solar panels anyway.
  • System Design and Engineering: Figuring out how many solar panels fit on your roof and how to make them work best needs a pro.
  • Sales and Marketing: Solar companies spend money on ads, explaining solar power to people, and finding new customers.
  • Installation Labor: Paying a pro to put in your solar panels safely and quickly.
  • Financing Costs: If you opt for financing your solar system, there might be loan origination fees and interest rates to consider.
  • System Monitoring: Some solar companies can watch how your panels are doing for you, like a subscription to a service. This might cost extra.
  • Interconnection Fees: The utility company might charge a fee to connect your solar system to their grid.

The impact of soft costs can be significant. Solar panel costs include more than just the price of the panels themselves. There are additional fees like permits and installer work that can add up to a significant portion of the total cost. This is in contrast to the cost of the solar panels and hardware itself, which has seen a significant decrease in recent years.

Not all of the cost of solar panels is for the panels themselves. There are extra fees like permits and paying the people who install them. Knowing about these extra costs can help you decide if solar panels are right for your home. Get quotes from a few different solar companies and ask them to explain their pricing so you know exactly what you’re paying for.

Here are the sources you can use for the information on solar panel soft costs:

  • National Renewable Energy Laboratory (NREL): NREL is a leading U.S. Department of Energy laboratory for renewable energy research. Their website is a valuable resource for solar energy information. Look for reports or articles related to solar photovoltaic (PV) system costs.
    • You can likely find the specific statistic about soft costs being over 65% of the total cost in a recent NREL report or on their website.
  • Solar Energy Industries Association (SEIA): The SEIA is the national trade association for the solar energy industry in the United States. Their website offers resources and publications on various solar energy topics, including solar PV system costs.
    • SEIA publishes a report titled “Solar Market Insight Report” which might discuss the breakdown of solar system costs, including soft costs.
