Solar Panel Maintenance Guide for Maximum Efficiency

Solar Panel Maintenance Guide for Maximum Efficiency

Solar Panels can withstand a lot, but they still require maintenance. Proper solar panel maintenance ensures that you will get the most out of your solar panel system. 

Keeping your solar panels repaired, clean, and free of debris extends their lifespan and keeps them functioning at the highest level. 

Let’s dive into solar panel maintenance to find out everything we need to know about properly maintaining solar panels and maximizing efficiency.

Solar Panel Maintenance: What You Need To Know

Going solar is a great way to offset energy costs and do something good for the environment, and well-maintained solar panels will guarantee that you get the most out of your investment. 

Maintaining solar panels includes routine cleanings and inspections. Checking the panels and wiring for damage or general wear and tear is necessary. Likewise, cumulative dirt and debris that block the ability of panels to absorb maximum sunlight should be removed. 

There are, however, a few things you need to know before cleaning your panels to avoid potential damage.

Inspecting Solar Panels

It is a good rule of thumb to schedule an annual, professional inspection. Even if you routinely perform maintenance checks yourself, an experienced technician will be able to more thoroughly assess the situation and catch potential issues you may have missed.

Maintenance Frequency

While some manufacturers recommend annual to quarterly maintenance, there really isn’t an exact science. How often you clean your panels is up to you, and most homeowners with solar panels clean them twice a year. 

If you are inspecting and cleaning them yourself — and there have been no drastic changes in productivity — chances are you will not require significant maintenance.

Maintenance Indicators

A key indicator that your solar panels require maintenance is performance. If you have noticed an extended period of low energy production — sans any substantial seasonal changes — a cleaning, debris check, or professional inspection could be required. 

Monitor and track your energy output. If your panels are still relatively new, fluctuations in output likely indicate an immediate issue that needs to be addressed. 

Additionally, if you have experienced any amount of severe weather, it is a good idea to check out your solar panels regardless of productivity to ensure there is no superficial or structural damage that may compromise your system.

Solar Panels for Your Roof: What You Need to Know

Solar Panels for Your Roof: What You Need to Know

As solar panels are fast becoming a familiar home feature, some homeowners have concerns about the installation process and potential roof damage. These worries, however, are easily allayed as rooftop solar is not only safe when installed correctly, they offer benefits they can extend the lifespan of your roof. 

Take a look at this breakdown of the installation process and hidden benefits of installing solar panels on your roof. 

How Are Roof Solar Panels Installed?

The average person is not an expert on the solar installation process, so it is reasonable to have reservations about adding large pieces of equipment to your roof.

The roof installation process, however, is safe and simple. While drilling holes is necessary for most solar roof installations, installers follow strict measures to make sure that installation area remains sealed and solid. 

Holes are drilled into the roof for lag bolts to support racking that secures the solar panels. These bolt fixtures are weather resistant and sealed with a tar flashing under the roof tile and a subsequent outer sealant for extra protection. 

Residential installation of solar panels

Are Solar Panels Damaging to Your Roof?

No, solar panels are not harmful to your roof when installed properly by experienced installation experts. The structural integrity of your roof will remain safe and sound during and after the solar panel installation process. 

Other than the well-sealed holes required for bolt fixtures, homeowners will likely worry about the extra weight that is being added to the roof. The average residential roof, however, is able to hold between 20 and 100 pounds of additional weight per square foot, which is much more than enough structural strength to support up to 30 solar panels.

What is the Average Lifespan of a Roof?

Regular roof maintenance and materials generally determine the lifespan of a roof. On average, residential asphalt shingle roofs last around 15 to 30 years, however, roofs made with more expensive materials can last much longer with diligent inspection and maintenance habits.

Can Solar Panels Make Your Roof Last Longer

Yes, one of the lesser acknowledged benefits of installing solar panels on your roof is that they add protection from harmful sunlight and damaging weather that shorten the lifespan of your roof. 

Solar panels absorb harmful sun rays that can quickly age your roofing materials. They also allow airflow between the panels and roof while blocking the sunlight from heating your shingles, which helps to keep your home cooler in the hot summer months. This is a nice, extra benefit to offset your already reduced energy bills.

If you live in a cold climate that experiences regular annual snowfall and ice, your solar panels can shield your roof, protecting it from ice damage and overexposure to moisture from snowmelt.

Get Your Roof Solar Panels Today!

Now that you know your roof will not only be unharmed by solar panels, but that they can actually make your roof last longer, the decision to go solar has never been easier. 

If you still have concerns about the installation process or other potential benefits, give Gurr Brothers Energy a call today for all the info you need on rooftop solar panels!

Solar Panels and Cloudy Weather

Solar Panels and Cloudy Weather

One of the key concerns surrounding solar panel systems is weather. Do they work well, if at all, on cloudy days? Potential panel purchasers wonder how overcast conditions will affect their overall investment while new panel owners worry about energy production during days without direct sunlight. 

Well, all uneasiness can be allayed as, yes, of course solar panels are still productive in less-than-ideal weather conditions. Let’s examine exactly how solar panels are affected by cloudy weather.

Do Solar Panels Work on Cloudy Days?

The short answer is yes, panels are still productive on cloudy days. Their level of efficiency, however, will be determined by the quality of the solar panels and cloud density. Considering all variables, panels will operate at around 10 to 25 percent of their normal capacity. If any amount of sunlight is getting through, then solar panels will still generate energy.

Solar panels on house rooftop

Do Solar Panels Work on Rainy Days?

Again, solar panels can work on rainy days, but the level of cloud coverage is a factor. Dense rain clouds will significantly restrict sunlight, resulting in little to no energy production, however, a benefit of rainfall is that it cleans your panels of dust and debris, making them more productive when the clouds clear.

What Kind of Solar Panels are Best for Cloudy Weather?

Solar panels that utilize monocrystalline silicon cells yield the highest level of efficiency. They are also long-lasting and require less space than other types of solar panels. 

Other exciting solar innovations on the horizon — like Axial Graded Index Lenses (AGILE) and ultralight fabric solar cells — promise to increase solar panel efficiency and productivity.

Don’t Forget About Net Metering and Energy Storage

Whether you are considering going solar, or are a new system owner with concerns about energy production during cloudy conditions, remember that there are surplus mechanisms in place to ensure that you are energy secure through periods of low productivity. 

During sunny days, your panels will likely produce excess energy. If your panel system is connected to a grid — as most residential solar panel systems are — you can benefit from net metering, which credits surplus energy to the power grid for later use when your panels are less productive. This comes in handy during periods of bad weather, or if your panels require repair. 

Another option to offset cloudy weather is battery storage. Solar battery technology is improving exponentially, and many solar users prefer to go completely off grid. Lithium-ion batteries are the most common batteries for residential systems. Rather than sending surplus energy back to the grid, it can be stored for use when your panels are not producing energy.

The Silver Lining

Don’t let clouds cast doubt on your decision to go solar. While gray skies can prevent solar panels from producing at full capacity, the good news is they still generate energy from any penetrating sunlight and will typically create a surplus during days of direct sunlight that can offset occasional gloomy weather. Get your head out of the clouds and contact Gurr Brothers Energy today to learn more about going solar!

Solar Innovations to Look Out for in 2023

Solar Innovations to Look Out for in 2023

Innovations in the solar industry have been increasing exponentially, and 2023 is poised to present some pretty awesome advancements in the solar panel industry. Photovoltaic (PV) cells are becoming lighter, cheaper, and more efficient. 

Let’s check out some of the solar trends and innovations to look out for in 2023.

Ultralight Solar Fabric Cells

At a weight one-hundredth that of standard solar panels, researchers at MIT have developed ultralight fabric solar cells that can convert just about any surface into an efficient source of energy. 

 

These ultralight fabric solar cells are paper-thin, tough as nails, and can generate almost 20 times the power per kilogram of conventional PV panels and — due to their durability, transportability, and easy installation — the possibilities for integration are endless.

Solar Panel

Transparent Solar Panels

The prospect of transparent solar panels is an exciting one indeed. Consider the applications! All glass on buildings and cars could be actively generating energy, but how do they work? Well, transparent solar panels can generate energy in a couple of ways: 

  • Quantum dot technology utilizes a light-absorbing insert between glass panels that reflects absorbed energy to the energy-generating edges of the installation. 
  • A transparent coating that absorbs infrared and ultraviolet light can be applied to windows to generate energy. 

Some electric vehicle companies are already integrating solar panels as a standard feature, and while charging stations will still be necessary, car panels could definitely offset charging intervals. Transparent panels are developing rapidly and could be available for residential and commercial use this year!

Axial Graded Index Lenses (AGILE)

For maximum efficiency, standard solar panels require direct sunlight, making them less productive during certain times of the day or under cloud cover. Some people have opted for expensive automated systems that track the sun throughout the day for optimal surface sunlight angles. Well, engineers at Stanford have designed a pyramidal optical concentrator that researchers refer to as AGILE. It collects and concentrates sunlight from any angle.

The ingenious design of these lenses allows for circuitry and cooling in the narrow areas of the pyramidal shape and reduces overall costs by requiring a smaller surface area than standard solar panels.

A Shift in Materials

Silicon, the foundational material of photovoltaic panels, could be replaced by organic photovoltaic (OPV) solar cells and halide perovskites. Scientists are hopeful in these materials for their efficiency and low cost.  

Some benefits of OPV and Halide Perovskites include: 

  • Low manufacturing cost and material abundance 
  • Wide range of applications / flexibility 
  • Lightweight and easy to install

What You Need to Know About Commercial Solar

What You Need to Know About Commercial Solar

Commercial solar — also known as Commercial and Industrial solar (C&I) — is sandwiched somewhere between utility-scale solar and residential solar. There are, however, some crucial characteristics that differentiate C&I from residential. 

Let’s dive into commercial solar and find out what you need to know about getting solar for your business.

What is Commercial Solar?

Typically much larger installations than residential solar panel systems, commercial solar covers a wide range of customers including: 

  • Small businesses 
  • Large corporations 
  • Nonprofits
  • Universities and schools
  • Governments
Top view Solar Cell on Warehouse Factory. Solor photo voltaic panels system power or Solar Cell

How is Commercial Solar Measured?

Solar is measured in kilowatt hours (kWh). Between 1,000 kWh and 2,000 kWh are generated by a 1 kW system. One megawatt (MW) is equal to 1000 kilowatts. An average residential solar panel system needs about 5 kW to 8.5 kW per day while a commercial system may require several MW. 

You can calculate your hourly panel energy production requirements by dividing the necessary average hourly wattage by your area’s daily peak sunlight hours. On average a medium-sized business requires a 70-panel solar system.

How Much Does Commercial Solar Cost?

There are many factors to consider when figuring the costs of commercial solar with prices ranging from $50,000 to $600,000. The size of the panel system needed will depend on the requisite kilowatts to cover daily energy consumption. Before applying federal solar tax incentives, the price per watt for commercial panels is between $2.50 and $3.22.

Let’s break down some of the average commercial prices with the 30% federal tax credit: 

 

Kilowatt Hours (kWh) Average Price

25 kWh system

$50,000
50 kWh system
$100,000
100 kWh system
$300,000
250 kWh system
$600,000
Solar panel station

What Are the Benefits of Commercial Solar?

With the average business owner’s monthly power bill coming in at just under $2,000 per month, commercial solar panels have been shown to reduce that by 75 percent. It is important to remember that solar is a long-term investment. It may take a little time to offset initial costs, but the pros of converting your business to solar are worth it. Some of the immediate benefits include, but are not limited to:  

  • Tax Credits: You can get some money back at the end of the tax year thanks to the extension of the Solar Investment Tax Credit (ITC).  
  • Energy Independence: You are no longer at the mercy of the power company, and with billing mechanisms like net metering, they may end up owing you energy! 
  • Reduces Overhead: Installing commercial solar panels can substantially reduce regular maintenance and operating costs.

Increases Value: Commercial buildings that are already equipped with solar panels are in high demand.

Tax Credits Claim Return Deduction Refund Concept

What You Should Know About the Solar Tax Credit Extension for 2023

What You Should Know About the Solar Tax Credit Extension for 2023

The Solar Investment Tax Credit

The Solar Investment Tax Credit (ITC) has been creating jobs and helping the solar industry grow since 2006. It was set to drop to 22 percent at the end of 2022, but will instead see a 30 percent increase for the next 9 years thanks to the August 2022 signing of the Inflation Reduction Act. 

Under section 25D of the tax code, the 30 percent credit is available for residential installations and is also redeemable for panels put in during the 2022 tax year. New wage and apprenticeship standards will drop the commercial solar rate to 6 percent with an additional 24 percent on tap after new labor standards are met.

How Does it Work?

If you installed a solar panel system in 2022, or plan to do so in the next 9 years, you will be able to reduce your income tax for that year by 30 percent of what your solar panel system cost. For example, if you install a $15,000 panel system, you can pay $4,500 less in income tax for that year.  

Eligibility for the ITC is quite simple and depends on a few factors.

  • Your solar panel system must be new and installed during the active credit period. 
  • You must own the home or property where the panels are installed (Non-primary residences also qualify). 
  • You must own the solar panel system or be financing it through a loan (Leased systems do not qualify). 

To claim your tax credit — if you are eligible to receive the ITC — you must file Form 5695 with your taxes for the installation year.

What Expenditures Does the ITC Cover?

Many facets of your solar panel system — including solar batteries, additional equipment, and labor fees — are covered by the ITC. Additional equipment refers to things like mounting gear, inverters, and wiring while labor fees encompass general installation, site prep, permits, and inspections.

Tax Credits Claim Return Deduction Refund Concept

Does the Unused Credit Carry Over?

Yes! Another helpful financial feature of the ITC is that remaining credits can carry over to the next tax year. If you owe less on your federal taxes than the amount of your solar reduction percentage, the remainder rolls over to the following year and so on, until you have fully used your solar credits.

When Does the Extension Expire?

The 30 percent rate will run until 2033, so there is plenty of time to take advantage of the incentive. In 2034 it will drop to 26 percent and phase out by 2035. There is, however, potential for another extension, which is likely as this policy has been wildly successful at creating new jobs and expanding the solar industry.

Take Advantage of the Solar ITC Credit

The ITC has been a crucial policy in incentivizing green energy in the United States. This extension serves as an excellent impetus to contact Gurr Brothers Energy and go solar in 2023. The growth of solar will be exponential in the coming years, so everyone should take advantage of this cost-effective credit while they can and become part of the green energy future!

Net Metering: What Is It and How Does It Work?

Net Metering: What Is It and How Does It Work?

What is Net Metering?

With the advancements in solar panel efficiency, more energy can be generated during daylight hours than is actually needed. Net metering or net energy metering (NEM) allows excess energy — 20 percent to 40 percent on average — to be sent from net-metered homes back to the grid on credit. During periods of low energy generation, the grid will send energy back. The difference can be calculated monthly or annually, and the homeowner is billed for their net usage, which can often result in no bill at all.

How Does Net Metering Work?

Most solar panel systems will be connected to a grid unless the homeowner opts for battery storage, which gives them total control over their own energy. Batteries, however, run out and are expensive to replace. Many homeowners prefer net metering as a failsafe billing mechanism. 

Smart Energy Meter In Kitchen Measuring Energy Efficiency With Figure In Background

Once your net-metered solar panel system is installed and overproducing, that extra energy will be sent to the grid. As you send excess energy to the grid, your meter will run in reverse, building credited energy for later use when your panels are producing less energy. NEM helps to balance fluctuations in seasonal and regional energy generation for a consistent and reliable year-round power supply.

Common Net Metering Misconceptions

The power company sending you actual money is a common misconception about net metering. As nice as it may sound, there is unfortunately no monetary exchange for excess energy. However, the more surplus energy sent to the power grid from your net-metered system, the more your meter runs backwards and accumulates credited energy. This will more often than not result in your net energy usage being less than what is produced and sent back to the grid, and therefore, bye bye energy bill. 

Another misconception about net metering is that it is federally regulated. While NEM is federally mandated, there are state-level variations in regulations. Some states require customers to haggle with utility companies while other states are actively developing alternative strategies that favor utility companies.   

Additionally, many homeowners with solar systems are under the impression that net metering is the only form of surplus solar solatium, but several states — Hawaii, New York, and Louisiana to name a few — have other renewable remuneration solutions that do not involve NEM at all.

Does Net Metering Make Solar Worthwhile?

Overall, yes, net metering helps make solar a smart investment! NEM is a foundational aspect of the solar industry that is still in the process of being perfected. Power companies are facing an inevitable future that involves an ever-relinquishing grip on energy allocation, so 2023 is a great year to contact Gurr Brothers Energy and get your net-metered or battery storage solar panel system up and running.

The Solar Industry’s Bright Future

The Solar Industry’s Bright Future

The Direction of Solar

Thanks to steadily decreasing solar costs and federal tax credits, solar installations around the country are on the rise. However, even with increased efficiency and falling solar prices, only about half of Americans are willing to foot the full bill, making solar subsidies an imperative benefit for the industry heading into 2023.

Observable Solar Trends of 2022

The Solar Industries Energy Association (SEIA) states that from 2022’s first quarter 1 to fourth quarter saw a decrease in overall installations of solar panels when compared to 2021, although, residential installations have had a record-breaking Q1, and observable quarterly increases over 2021’s residential solar panel installations.

First to Fourth Quarter Total Solar Installations

In the first quarter of 2022, solar decreased by 24% compared to Q1 2021 while fourth quarter of 2022 installations decreased by 52% when compared to the fourth quarter of 2021.

Workers installing solar panel on roof framework of new home, Netherlands

First to Fourth Quarter Residential Solar Installations

In the first quarter of 2022, residential solar increased by 30% compared to the first quarter of 2021 while the fourth quarter of 2022 residential solar installations increased by 5% when compared to the fourth quarter of 2021.

Factors in Fluctuations

While several factors have influenced a decline in overall solar installations — most notably supply chain issues related to the pandemic, unemployment rates, and an era of international inflation — the increase in residential installations is invigorating and statistically signifies a people’s enthusiasm for renewables. Newly-passed legislation is also set to support the renewable energy industry going into the first quarter of 2023, and the future of solar is looking bright!

What Will 2023 Bring

An Optimistic Take

Residential installations are expected to increase in 2023 as homeowners continue to benefit from solar subsidies. California is going a step further than other states by requiring all solar panels on all new residential builds, and as battery storage technology becomes increasingly more efficient and energy suppliers become more decentralized, energy storage will likely become an important asset for grid systems in securing reliable, widely available, and adaptable energy solutions. This will influence investors going into 2023 and almost certainly lead to an increase in solar installations.

A Pessimistic Take

PV modules and solar shipments coming from South East Asia could be disrupted by tariffs and possibly cause a drop in the industry, however, there is no certainty of tariffs or how long they will last, and US agreements with South Korea could make the United States a top superconductor producer. Likewise, an increase in polysilicon manufacturing by the end of the year could facilitate a decrease in 2023 solar prices.

Solar panel

Should We All Go Solar?

Yes! Solar panels are in all of our futures as there is a desperate need to reduce global carbon emissions. The pros of solar panels overshoot the cons — and with the exception of a few possible geopolitical speedbumps — 2023 will be a critical year for the solar industry. 


Installing solar panels will not only help to heal mother nature, but it will assuredly save you money over time and raise your property’s value.
