Solar power purchase agreements (PPAs)

A solar power purchase agreement (PPA) is a contract between a business and a solar energy provider. The provider installs, owns, and maintains the solar panels on the business’s property. The business then agrees to purchase the electricity generated by the panels at a predetermined rate. This option requires little to no upfront cost for the business. For example, a large hotel chain in California entered into a PPA with a solar company. The hotel was able to reduce its electricity bills by 30% within the first year of the agreement.
Pro Tip: When considering a PPA, carefully review the terms of the electricity rate. Make sure it includes provisions for future rate adjustments based on inflation or other factors.

Solar leases

Solar leases are similar to PPAs, but instead of purchasing the electricity, the business pays a fixed monthly fee to lease the solar panels. This option also has low upfront costs. A small office building in Texas leased solar panels and was able to offset 80% of its energy consumption. This not only reduced their energy bills but also improved their corporate social responsibility image.
Pro Tip: Check the lease agreement for any maintenance responsibilities. Ensure that the leasing company is responsible for repairs and upkeep.

Energy services agreements

Under an energy services agreement, an energy service company (ESCO) provides a comprehensive energy solution to the business. This can include solar panel installation, energy management systems, and efficiency upgrades. The ESCO is paid based on the energy savings achieved. A large warehouse in Florida partnered with an ESCO. The ESCO installed solar panels and optimized the warehouse’s lighting and HVAC systems. As a result, the warehouse achieved a 40% reduction in energy costs.
Pro Tip: Look for ESCOs with a proven track record and certifications in energy efficiency and solar installations.

Tax equity financing structures

Sale leasebacks

In a sale leaseback arrangement, the business sells its solar panel system to an investor and then leases it back. This provides the business with upfront cash while allowing them to continue using the solar panels. A large hospital in New York used a sale leaseback to finance its solar panel installation. The hospital received a lump sum payment from the investor and was able to offset a significant portion of its energy costs.

Partnership flips

Partnership flips involve a partnership between a business and an investor. The investor provides the upfront capital for the solar panel installation, and the partners share the tax benefits and profits. Once a certain financial milestone is reached, the ownership structure "flips," and the business takes over a larger share of the ownership.
Pro Tip: Consult with a tax professional when considering tax equity financing structures to ensure compliance with all tax laws.

Cash or loan purchases

Some businesses may choose to purchase solar panels outright with cash or through a loan. Cash purchases eliminate the need for ongoing payments and allow the business to fully own the solar panel system. A commercial real estate company in Arizona purchased solar panels for its office buildings using cash. This decision not only reduced its long – term energy costs but also increased the value of the properties.
A solar loan, on the other hand, allows businesses to finance up to 100% of the solar panel installation. Many financial institutions offer competitive rates and no dealer fees on solar loans.
Pro Tip: Compare loan offers from multiple lenders to get the best terms and interest rates.

Interaction with government incentives

Grants for direct purchase

Governments around the world offer various incentives to encourage the adoption of solar energy in the commercial sector. Grants for direct purchase are one such incentive. In the United States, for example, some states offer grants to businesses that purchase and install solar panels. A school district in Colorado received a government grant to install solar panels on its schools.

Understanding how to calculate solar energy generation is crucial for commercial entities looking to make the most of this sustainable energy source.

General approach

Factors considered

When taking a general approach to calculating energy generation from solar panels in commercial buildings, multiple factors come into play. One key factor is the location of the building. For instance, a warehouse located in a sunny desert region will generate more solar energy compared to one in a cloudy coastal area. The tilt and orientation of the solar panels also matter significantly. Panels that are tilted at an angle that maximizes sun exposure and oriented towards the sun will produce more energy.
The efficiency of the solar panels is another important consideration. High – efficiency panels, though often more expensive, can convert a greater percentage of sunlight into electricity. For example, in a large office building in Phoenix, using high – efficiency solar panels on the rooftops led to a 20% increase in energy generation compared to standard panels.
Pro Tip: Conduct a detailed on – site assessment of your commercial property. This will help you accurately determine the ideal tilt, orientation, and panel efficiency based on your specific location.

Specific calculation methods

Based on basic factors

To calculate solar energy generation based on basic factors, you start by determining the size of your solar panel system (in watts). Then, you need to consider the average sunlight hours your location receives per day. Multiply the system size by the average sunlight hours, and then factor in the panel efficiency.
Let’s take a hotel in Miami as a case study. Suppose the hotel has a 100 – kilowatt solar panel system. Miami gets an average of 6 sunlight hours per day, and the panels have an efficiency of 80%. The daily energy generation would be calculated as follows: 100,000 watts x 6 hours x 0.8 = 480,000 watt – hours or 480 kilowatt – hours per day.
Pro Tip: Use online solar calculators that can take into account your specific location’s sunlight hours, panel efficiency, and system size to simplify the calculation process.

Using the daily peak – sun – hours method

The daily peak – sun – hours method is a more refined way of calculating energy generation. Peak – sun – hours are the number of hours when the sun’s intensity is at its maximum. This method provides a more accurate estimate as it focuses on the high – productivity hours of sunlight.
First, determine the peak – sun – hours for your location (this data can often be found from local meteorological services). Then, multiply the peak – sun – hours by the system size and the panel efficiency. As recommended by PVWatts, a popular industry tool for solar energy calculations, this method can offer a more realistic projection of energy generation.
For a large retail store in Las Vegas, which has around 7 peak – sun – hours per day, a 200 – kilowatt system with 85% efficiency would generate 200,000 watts x 7 hours x 0.85 = 1,190,000 watt – hours or 1190 kilowatt – hours per day.
Key Takeaways:

• Calculating solar energy generation for commercial buildings involves considering factors like location, panel tilt, orientation, and efficiency.
• You can use basic factor calculations or the more accurate daily peak – sun – hours method.
• Utilize online calculators and industry – recommended tools for accurate and simplified calculations.
