Key policies affecting the solar industry in 2022 include:

Net metering allows solar energy system owners to receive credit for excess electricity generated and fed back into the grid. As of 2022, 38 states and the District of Columbia have mandatory net metering policies in place, while several other states have voluntary utility programs according to Database of State Incentives for Renewables & Efficiency. Net metering policies can significantly impact the financial viability of solar projects for SMBs, as they can offset electricity costs and provide a return on investment.

RPS policies require utilities to source a certain percentage of their electricity from renewable energy sources. In 2022, 30 states and the District of Columbia had enforceable RPS policies, with varying targets and timelines as reported by National Conference of State Legislatures (NCSL). RPS policies can drive demand for solar energy and create market opportunities for SMBs in the solar industry.

Interconnection standards govern the process of connecting solar energy systems to the grid. These standards can impact the ease and cost of connecting solar projects, affecting the overall project economics for SMBs. In 2022, the Interstate Renewable Energy Council (IREC) released its updated Model Interconnection Procedures, which aim to streamline the interconnection process and reduce barriers for solar energy system owners.

In the solar energy industry, revenue recognition is guided by accounting principles such as the Financial Accounting Standards Board's (FASB) Accounting Standards Codification (ASC) 606, which outlines the criteria for recognizing revenue from contracts with customers. Key considerations in revenue recognition for solar projects include project completion milestones, performance obligations, and long-term service agreements. For instance, revenue may be recognized upon meeting specific milestones, such as the installation of solar panels or the achievement of a particular energy output. Additionally, performance obligations, such as warranties and maintenance services, must be accounted for separately, with revenue recognized over the service period. Long-term service agreements further complicate revenue recognition, as they often involve multiple performance obligations and variable consideration, requiring careful allocation of the transaction price. Key aspects include:

Assessing the return on investment (ROI) of solar projects helps businesses evaluate the financial benefits of solar adoption. In 2022, the average payback period for commercial solar installations in the United States ranged from 3 to 7 years, depending on factors such as system size, location, and available incentives [source: EnergySage]. By calculating the ROI, SMBs can determine the potential profitability of solar projects and make informed decisions about whether to invest in solar energy.
Properly depreciating solar assets can optimize tax deductions and improve project economics. Under the Modified Accelerated Cost Recovery System (MACRS), businesses in the United States can depreciate solar assets over a five-year period, allowing them to recover a sizable portion of their investment through tax deductions. In 2022, the bonus depreciation rate was 100%, enabling businesses to deduct the entire cost of eligible solar assets in the first year as stated by Internal Revenue Service (IRS). By understanding and applying depreciation rules, SMBs can maximize tax benefits and enhance the financial viability of their solar projects

Developing accurate financial models can help businesses forecast cash flows, assess risks, and make informed investment decisions. Financial models for solar projects typically include variables such as system costs, energy production, electricity rates, incentives, and financing options. In 2022, tools such as the National Renewable Energy Laboratory's (NREL) System Advisor Model (SAM) were available to help SMBs create detailed financial models for their solar projects.
