What you need to know about Solar Energy in Maryland

While citizens in Maryland belonging to municipal electric systems and rural cooperative systems cannot choose their electricity supplier, this is not the case for most residents. Even though local electric companies are still the ones in charge of delivering electricity to most homes, you can now choose which company generates the electricity you consume.

Some of the biggest electricity companies in Maryland are First Energy, Baltimore Gas and Electric Company (BGE), Delmarva Power & Light Company, Potomac Electric Power Company (Pepco), The Potomac Edison Company, and others. Most of the companies that distribute electricity in Maryland are required by the Maryland Public Services Commission (PSC) to regulate their utility rates, charges, and rules, following the PSC mandates.

Considering these regulations, most of the companies have similar electricity rates. Therefore, it is important for Maryland residents to correctly choose their electricity company depending on what is best for them. While some companies have fixed electricity rates, others vary their rates on a monthly basis.

Maryland residents usually pay electricity bills 20.56% more expensive than the national average. This state has an average electricity rate of 12.84 ¢ per kilowatt-hour consumed, 8.08% higher than the national average, positioning MD as the 15th state in the national rank.

Considering that using renewable energy reduces greenhouse gas emissions and decreases electricity bills, solar energy is on-demand in this state. As a result, many Maryland residents are currently opting to install rooftop solar systems that provide enough energy to supply part or all of their household energy consumption.

Are solar panels worth it in Maryland?

Due to high-cost electricity rates, elevated energy consumption, and the overall cost of monthly electrical bills in Maryland, going solar can be extremely beneficial for residents in this state.

Maryland counts with an excellent potential to produce solar energy, being a state listed as the 17th in the Solar Power Potential Ranking according to the NDEE-Energy & Assistance Division.

With an average cost of 12.84 ¢/kWh, Maryland's electricity rates are 32% higher than those in states like Washington, Idaho, Arkansas, or Louisiana. The state electricity rates are even 8.08% more expensive than the national average. An average electricity bill in Maryland can cost around $127.92, which is 26% higher than bills in California, 35% than those in Washington, and even 69% higher than Utah.

The average Maryland home consumes up to 1000 kilowatts-hour a month and 12,000 kilowatt-hours per year. Maryland ranks as the 40th state in the Energy Consumption Ranking, with average residential power consumption that can be 11.3% higher than the national average, 903 kWh/month.

An average 5 kW DC solar system installed at a home in Maryland can generate up to 7,000 kWh/year, supplying enough solar energy to cover 58% of the power needs for residents in the state. According to the NREL (National Renewable Energy Laboratory) database, an 8.7 – 9 kW DC rooftop solar system is the perfect fit to provide enough solar power for Maryland's average home power consumption.

For rooftop solar systems of 8 – 9 kW DC, the price may vary from $22,079 to $23,913 before incentives. After the ITC incentive, the price reduces to $16,339 – $17,696. Still, you can reduce the overall cost even further after local incentives for residential photovoltaic (PV) systems in Maryland. The payback period for a system this size can be as fast as 6.1 to 7.5 years; you will still be saving money after the investment return date.

Considering the lifespan of a solar inverter which is the heart of your solar system, the average PV system can last around 25 years. So for an energy PV system of 8 kW DC after 25 years, you would have saved on average up to $38,000, which is 232% of the cost of your solar system after incentives.

If you are considering going solar in Maryland, the time to decide is now. The most remunerative federal incentive gives you a 26% dollar-for-dollar reduction from the overall cost of your solar system. Still, this incentive is reduced to 22% by 2023 and 10% for future years. So Maryland residents who go solar by 2021 or 2022 will enjoy more profitable incentives than those who do it 2 or 3 years later.

How much energy can your solar system produce?

When deciding to go solar in Maryland and sizing your rooftop solar system, it is important to factor in the solar radiation levels. According to NREL, Maryland receives 3.05 – 6.4 kilowatt-hours per square meter a day depending on the month and geographical location within the state, positioning Maryland as the 17th state in the Solar Power Potential Ranking.

The solar radiation levels measured in Maryland can be translated as 3 to 4.6 full hours of solar generation at maximum efficiency by your rooftop PV system. For example, an 8.7 kW DC solar system in Maryland can provide an annual power generation of 11,590 kWh up to 12,594 kWh in AC energy.

On average, Maryland homes consume around 12000 kWh per year. For this power consumption rate, a medium-size solar residential system such as the 8.7 – 9 kW DC one can provide enough solar energy to supply the home's electrical needs for the whole year. A rooftop PV system this size may ensure yearly savings of $1,488.15 up to $1,617.06 in electrical utility bills.

Maryland allows for a wider size in solar system installations than other states do. Maryland residents can install solar systems that generate as much as 200% of their annual electricity consumption. With Net Metering, your excess generated power will be credited at full retail price for other electrical bills throughout the year. At the end of the 12-month billing cycle closing in April, you will be compensated for the excess power generated at the average annual commodity electricity rate.

Maryland PV system payment options

When deciding to install a rooftop solar system in Maryland, you can choose from several payment options. Depending on the payment plan you choose, you might be eligible for federal and local incentives that provide you with many remunerative benefits. To help you choose the best solar plan for you, we will break down each payment option available for Maryland residents.

  • Solar purchase/cash: A simple solar purchase with cash is the most straightforward payment plan to obtain your PV generation system. You get full ownership of your solar system for this payment option and are eligible for federal and local incentives.
  • Solar loan: A solar loan is the best method to finance the purchase and installation of your solar system. When choosing this payment plan, you can pick a financial institution for your loan. In some cases, the solar company will provide you with a loan themselves. If you choose a solar loan, you should look for the choice that provides you with the most benefits.
  • Solar leasing: One of the most curious options to use solar energy is opting for Solar Leasing. In this method, you pay monthly rent or lease for the installed solar panels, with the price being calculated depending on the size of the rooftop solar system. You do not have ownership of the PV system for this option, nor are you eligible for local or federal incentives.
  • Solar Power Purchase Agreement (Solar PPA): A Solar PPA consists of installing a PV system in your home. At the same time, you make direct payments for the energy you consume as if the solar company was your electric utility company. This option allows you to consume energy free from greenhouse gas emissions at a lower ¢/kWh rate than the regular electric rate and without paying for installing the rooftop solar system.

What are the Maryland solar panel incentives?

Maryland is an ambitious player in the solar industry. It provides residents who install solar systems with regular federal incentives and some attractive local incentives.

We will break down each of these incentives to further explain to you what are the financial benefits of going solar in Maryland and which solar panel incentives Maryland offers.

Federal Solar Investment Tax Credit (ITC)

The Federal Solar Investment Tax Credit is the federal incentive for PV systems owners. This incentive provides a 26% dollar-for-dollar reduction of the overall cost of your solar system against your federal income tax, allowing you to roll over these tax reductions for several years.

The ITC will remain at 26% up to the end of 2022. The incentive reduction will be lowered to 22% in 2023 and 10% for future years, which is why we recommend going solar by 2021 or 2022.

Solar Energy System Property Tax Exemption

Upgrading a home regularly increases the overall value of the property, which in consequence increases the federal and local taxes of a property. However, with the Solar Energy System Property Tax Exemption in Maryland, homeowners installing solar systems will be exempt from increasing their federal home taxes and local property taxes.

Solar Panel System Sales Tax Exemption

When purchasing most products, Maryland residents pay the regular 6% in sales taxes common throughout the US. However, after applying for the Solar Panel System Sales Tax Exemption, MD residents are allowed to reduce the overall cost of their whole rooftop solar system by 6%.

This incentive can be seen as a 6% discount for rooftop solar systems in Maryland. Adding this discount to the ITC would mean an overall discount of 32% for residential solar systems. To be eligible for this incentive in MD, you must install the PV system in a residential property eligible for net metering.

Maryland Solar Renewable Energy Credits

The Maryland SRECs is a program that encourages residents to install PV systems at their homes and helps the state achieve its ambitious solar goals. The program allows rooftop solar system owners to earn 1 credit called SREC by every megawatt-hour (MWh) produced by their PV system. Credits can later be sold at the SREC trade.

Maryland SREC price and SREC trade

You can sell the earned credits at the SREC trade market at a set price; by March 2022, the SREC bid price is $58.50. For reference, Maryland SREC price was $79.50 in March 2021.

Residential Clean Energy Rebate Program (R-CERP)

The Residential Clean Energy Rebate Program (R-CERP) is an excellent opportunity to reduce the payback period of purchased solar systems of 1 – 20 kW DC in Maryland. The R-CERP allows residents acquiring new rooftop solar systems to be eligible for a $1000 solar rebate. Other installations like Geothermal and Solar Water Heating systems are also eligible for the R-CERP rebate.

MD Net Metering program

The Maryland Net Metering Program works in a slightly different way than in other states by the end of the billing cycle. This is a billing mechanism crediting homeowners with installed rooftop solar systems for the excess energy they produce. With the MD Net Metering Program, you reduce the excess generated kWh from the consumption for future electrical utility bills within the same 12-month billing cycle, closing each April.

Net-metered generators with excess credits in generated power at the end of each 12-month billing cycle will be compensated for the extra credit at the average annual commodity electricity rate. This means that for every kWh generated surpassing 100% of your consumption, you will be compensated for the credits at a rate lower than the full retail price.
