What types of buildings can be solar powered?

Rooftop solar systems can be installed on most commercial, industrial, warehouse, retail and agricultural facilities. We will review your roof for suitability before finalizing a system plan. Ground-mounted and carport systems also offer excellent commercial solar options. PPM Solar has experience working with companies across Florida in various industries. PPM Solar has helped our commercial customers lower their energy costs with customized solar power systems to meet their needs.

What part of the solar installation process does PPM Solar manage?

PPM Solar has a dedicated commercial team that conducts project management from inception to completion. One of our solar experts performs an energy audit of your business. We then use that data to design a solar power system that fits your financial and energy needs. Once the system design is approved, PPM Solar begins the installation process. We use only highly qualified commercial PV panel installers. These installers work with various building and roof types and are trained to work with metal, asphalt, and TPO roofs. We take great care in roof protection and ensure no roof leak concerns.

How much does my business need to invest to own a solar power system on my property?

For customers who opt to self-finance their solar array, the solar power installation cost on your commercial property varies depending on the rebates and incentives available. Other factors include system size, how the roof is oriented toward the sun, roof type and location. PPM Solar has a team of experts who can show you how affordable solar energy can be. We will work with you to choose an efficient solar power system for your goals and budget. We can help arrange financing for your business to install a new solar power system with little or no upfront capital investment.

How do I estimate my company’s potential savings?

The design, system size, and how the panels are oriented toward the sun and the equipment you select will impact the output you can expect. Your energy demand and local utility rates are just some factors that will determine your total savings. As a premier solar installer in Florida for 14 years, PPM Solar has the expertise to evaluate your business’s property, from design to installation. A custom solar power system can effectively reduce your operating costs. This analysis is provided to you without obligation.

After rebates, how affordable is solar power for my commercial property? Why invest in solar power?

With generous federal rebates and incentives available, the total cost for a commercial solar power system is often much lower than expected. These cost-saving programs are:

  • The Federal Solar Investment Tax Credit (ITC)
  • Florida state sales tax exemption through Solar and CHP Sales Tax Exemption 
  • Florida Property Tax Abatement for Renewable Energy Property
  • Net Metering (sell your surplus energy back to the grid)
  • Government-backed Florida PACE (Property Assessed Clean Energy) Loan Program

Various financing options allow some businesses to install a new solar power system with no upfront capital expense and maintain a budget-neutral position, as energy savings are used in the short term to pay down any financing. After the note is satisfied, your solar power system’s energy drops right to your bottom line. In addition, your new solar power system will provide excellent price stability, safeguarding against future electricity rate increases. The experienced team at PPM Solar can show you how solar is often more affordable than staying with electricity from the grid.

Why invest now?

The cost of solar equipment, particularly solar panels, has been decreasing while the efficiency of solar panels has been increasing. Remember that some incentives, such as the Federal Investment Tax Credit (ITC), are scheduled to expire soon. The current Federal ITC for systems installed in 2022 is 26%. The ITC for installations in 2023 decreases to 22% and will expire in 2024, so don’t miss out by postponing action. PPM Solar is knowledgeable of current legislation in Florida and can help you understand the most advantageous programs that apply to your business’s project. The sooner you go solar, the sooner you begin saving.

Are rebates/incentives guaranteed?

While there are no statewide rebates in Florida, several cities have local rebates and grants. The rebates/grants amounts vary from city to city, and some require pre-approval for eligibility. Check with your local government before starting the solar installation process. Remember, there is no guarantee that a commercial solar incentive will be in effect in the future. However, PPM Solar guarantees to evaluate and access incentive programs in effect when you agree to have us install your new solar power system. Suppose an incentive program is eliminated after you have signed our agreement and before we have installed your system. In that case, we will either compensate you for the amount that incentive would have provided, or we will return your deposit, and you will not be obligated to move forward with your solar power project. PPM Solar wants you to be confident that you decided to install a new commercial solar power system with us.

In terms of financing, what loan options are typically available for commercial solar?

Florida has several options for commercial solar loans:

  • In-house financing through a solar installation company, such as PPM
  • Loans with banks, finance companies, credit unions, etc

   1. Small Business

   2. Secured Loans (with collateral)

   3. Unsecured Loans (no collateral)

What are the Commercial REAP (Rural Energy for America Program) and PACE (Property Assessed Clean Energy) programs?

REAP: Per, “REAP provides solar panel grant funding for up to 25% of new solar installation costs. The loan guarantees cover up to 75% of the solar project cost. These grants and loans are awarded on a competitive basis.”

PACE: Per, “The Florida PACE Program was created to facilitate and finance energy efficiency projects, renewable energy projects, and wind hardening projects for residents, organizations, institutions and businesses in participating municipalities in Florida, as authorized by Florida Statute 163.08.“ The PACE program is not a loan. It is a property assessment payback through your property taxes.

What size solar power system will my business need?

An energy expert at PPM Solar will meet with you to determine how much electricity your company uses and what space you have available for a solar power system. Based on that analysis and your budget, our in-house team of engineers will create a custom design for your facility that offers the best return on your investment. The optimum size of a solar array is not always the most extensive system but the most innovative system for your needs!

What manufacturers does PPM Solar use?

What happens to the excess electricity if my solar power system produces more energy than I need?

Any excess electricity generated that your business does not use may be useful to others in your community, so bi-directional meters are installed to allow for net metering.

What is a Net Metering?

Net metering is the process of providing a credit for any excess electricity your business’s solar power system produces and delivers to the power grid. While the state of Florida offers this program, the state’s net metering laws only apply to Investor-Owned Utilities (IOUs). Four companies currently cover 79% of statewide customers. 

  1. FPL- Florida Power & Light
  2. Duke Energy Florida
  3. TECO- Tampa Electric Company
  4. Florida Public Utilities Corporation

Municipal electric companies or rural electric co-ops cover the remainder of the Florida customers. 

PPM Solar’s experts can advise you about the programs available at your business location.

How long will my solar power system last?

In Florida, there are two types of solar panel warranties: 

  1. Performance-typically 10year 90% production and 25year 80% production
  2. Equipment Guarantee-typically 10-12 years


Testing and Certifications:

Solar systems manufactured or sold in Florida are required to comply with the Florida Solar Energy System (FSEC) standards.

The FSEC protects Florida consumers by working closely with the solar industry, research and development, and others to encourage using renewable energy sources.

What is an interconnection?

A Solar interconnection is the connection from your solar array to the utility grid. Most of the solar panels in the US are connected to the grid. Your utility company must approve this process. They will do an in-depth study to determine your system’s potential impacts on the grid.

What happens if the solar power goes out from a storm or rolling blackout?

In this case, your business solar power system will automatically turn off, and when the power comes back on, your solar system will turn itself back on automatically. Commercial property owners who want or need to have power available in storms or blackouts can invest in a battery backup system paired with their solar installation. PPM Solar can advise what energy storage options are available in this rapidly changing area related to solar power production. By installing batteries at the same time as solar, some or all of the battery costs may also be eligible for the Federal Investment Tax Credit.

How much sun does a solar power system need to generate electricity?

Two environmental factors are most significant in determining how much power your business’s solar energy system may generate: your position on the earth (latitude) and the history of weather conditions in your area. These factors are used to predict your business’s solar power system output. On average, Florida has 237 sunny days. The average length of each day and exposure to the sun in Florida is 5.67 hours, but solar panels still produce some power under cloudy skies. The seasonal variation of the sun is very predictable and well-documented. Most buildings in the northeast are well-suited for solar installations. PPM understands the factors that can influence your business’ solar output and can accurately predict what you can expect.

Can batteries be added to an existing commercial solar power system?

In a word, YES! The process is not as simple as just plugging in a new battery bank to the system, as most inverters are not designed to integrate with the battery bank. New Components will typically need to be added to make the batteries work with the existing inverter. Challenges can arise due to the strict guidelines for inverters and battery sizes. Adding new battery banks can be expensive, sometimes exceeding the cost of the solar system itself. 

  • During power outages, using AC Coupling allows you to charge the batteries. Essential appliances can be used if the need arises. 
  • DC Coupling uses a charge controller to connect the battery bank to the solar array directly. When using the DC Coupling, you must be on-site to turn on the solar charging to avoid drained batteries. The system will run, but the batteries will not recharge from solar unless the switch is manually turned on.
  • The most expensive option is to install a storage-ready inverter to replace the grid-tie inverter. While it is the most expensive option, it does work with all existing grid-tie systems, making this option the most flexible.

Does the Federal Investment Tax Credit (ITC) apply to new solar batteries?

If you are purchasing a new commercial solar power system and want it designed to include batteries, the entire cost of the new system may qualify for the ITC.  The IRS has ruled that taxpayers can claim a renewable energy tax credit to offset the cost of a battery system integrated with existing solar power equipment.  As tax regulations often change, PPM Solar strongly advises you to speak with your business’s financial advisers for tax advice before moving forward with your decision.

Can a battery replace my property’s generator?

One advantage of a commercial solar battery is that your business can draw from the stored power in the event of a blackout or system outage.  Depending on the size of the energy storage system and your business’s power requirements, it is possible to design a solar storage solution that could eliminate the need for your business to have a generator.

How much does a solar battery system cost?

Solar battery costs are widely varied and are higher for more significant batteries. Smaller lead-acid batteries can be purchased for as little as $200. Lithium-ion battery costs range from $7,000 to $14,000. Costs are also determined by kWh. For example:

  • $4,500-9,600 for 6kWh
  • $9,800-14,000 for 10kWh
  • $8,000-18,000 for 13kWh

These costs are for the batteries only. Installation is an added expense. PPM Solar’s experts can help you through the decision process to ensure you get the size battery needed for your business.

How long will my solar battery last?

How long a battery lasts is dependent on several factors. Major battery manufacturers rate the lifespan of their battery based on how often it is charged and discharged, and warranties are typically available that tie to that estimated lifespan. Speak with a PPM Solar battery expert to learn what battery system may best meet your business’s needs. The lifespan of the battery and warranties will be part of that conversation.
