Community Solar

“community shared solar” is defined as a solar-electric system that provides power and/or financial benefit to multiple community members.

David Feldman, Anna M. Brockway, Elaine Ulrich, and Robert Margolis,"Shared Solar: Current Landscape, Market Potential, and the Impact of Federal Securities Regulation" NREL,April 2015.[1].

Restrictions on Community solar

  • Uncertainty about the applicability of Securities and Exchange Commission (SEC) requirements i.e when and how shared solar program is considered as "security".
  • subject to regulation State and local laws.
  • uncertain tax credit applicability such as 25D for residential purposes only upto 30% which restricts off site solar plant users. Section 48 for business have ventures have similar difficulties.

What is security?

A security is an investment instrument issued by a corporation, government, or other organization that offers evidence of debt or equity. Any transaction that involves an investment of money in an enterprise, with an expectation of profits to be earned through the efforts of someone other than the investor, is a transaction involving a security. Community shared solar organizers must be sure to comply with both state and federal securities regulations, and avoid inadvertently offering a security.

There is a need of no action letter from SEC for shared solar project

To pass as Federal security there is a Howey Test criteria:

  • An investment of money
  • In a common enterprise
  • Based solely on the efforts of a promoter or a third party
  • For which there is an expectation of profits

To pass as state security there is Risk capital test criteria:

  • Funds are being raised for a business venture or enterprise
  • The transaction is offered indiscriminately to the public at large
  • The investors are substantially powerless to affect the success of the enterprise
  • The investors’ money is substantially at risk because it is inadequately secured.

Even if a project is classified as security there are exemptions

States having shared solar policies

  • Group net metering or VNM: California, Connecticut, Massachusetts, Maine, New Hampshire, Vermont
  • Statewide shared energy program: California, Colorado, Delaware, District of Columbia, Massachusetts, Minnesota
  • Incentives: Washington

Potential of Shared solar

It is estimated that 49% of households and 48% of businesses cannot host a PV system of adequate size on their property or virtually net meter an entire system themselves. By opening the market to these customers, shared solar could represent 32%–49% of the distributed PV market in 2020, growing cumulative PV deployment in 2015–2020 by 5.5–11.0 GW and representing $8.2–$16.3 billion of cumulative investment.


Jason Coughlin, Jennifer Grove, et al., "Guide to community solar: Utility, private, and non-profit project development"U.S. Department of Energy, 2011.

  • Great Overview of community shared solar
  • Three different models – group members to be located within the same utility service territory, require solar array. Also talks about some main methods of implementation - Comparison between three main models (Utility,Special purpose entity & Non profit)
  • Includes Various state policies to support community shared solar

Billing methods – Group billing, virtual net metering and joint ownership 1.Group billing – master metering, net metering ((total from utility – PV generation)/total participants) based on agreement 2.Virtual net metering – Credits appear on each individual customer’s bill, Colorado best example, Few examples of California, Colorado, Massachusetts, Delaware’s community solar program 3.Joint ownership – joint ownership between customer/owner and utility, businesses etc, Example of Maine and Washington’ s program

  • Tax policy & incentives
  • Security compliance – security laws are intended to protect individuals who provide financial support for a project with an expectation to receive profits from the efforts of others or with the expectation to receive a valuable benefit when the investor does not have control over managerial decisions of the venture.
  • Basic step by step guidelines for community solar program

Abstract - Combination of a Geographic Information System(GIS) and tools or multi-criteria decision making(MCDM) methods in order to obtain the evaluation of the optimal placement of photovoltaic solar power plants in the area of Cartagena(Region of Murcia),in south east Spain. The use of MCDM the criteria or factors are weighted in order to evaluate potential sites to locate a solar plant. Analysis and calculation of the weights of the factors are conducted using Analytic Hierarchy Process(AHP). The assessment of the alternatives according to their degree of adequacy was carried out through the TOPSIS method (Technique for Order Preference by Similarity to Ideal Solution). .

  • Detailed method for the evaluation of solar farm location.
  • Analysis and calculation of the weight of all relevant factors are conducted using Analytic Hierarchy process (AHP). AHP method was used to determine the importance of the different criteria used in the process.
  • Assessment of the alternatives is carried out through the TOPSIS method (This method ends with the calculation of the relative proximity to the ideal solution of each alternative that will be called Ranking.
  • Main criteria for selection of PV Farm with weight: Location(48.625%), climate(28.562%), Orographical(17.259%),Environmental(5.553%).
  • Complete case study for south-eastern Spain using Geographic Information System(GIS) system with Multi criteria decision making methods (GIS-MCDM).

Solar Power Prediction for Smart Community Microgrid (2016)[3]

Abstract - Microgrids will enable the integration of distributed renewable energy such as roof top solar panels within smart city communities. For microgrids to operate reliably and efficiently, prediction algorithms are important because of the fluctuation of solar energy and its dependence on weather. This paper presents a machine learning based algorithm, which learns a regression tree model with time of the day and humidity as main parameters.This work shows that solar panel prediction in Houston is heavily dependent on humidity of the region.

  • Application of regression tree algorithm for solar power prediction.
  • Various solar energy prediction techniques were discussed like Numeric weather prediction method (NWP), persistence method, Auto regressive Model, Support vector machines, Neural network technique etc.
  • Most Important variable to predict power are humidity, time of the day and sky condition etc.
  • Historical data for various variables for model learning through NOAA(The National Oceanic and Atmospheric Administration) are temperature, humidity, pressure, wind speed and wind direction
  • solar power production is inversely proportional to the humidity.


User-centered design for smart solar-powered micro-grid communities(2014)[4]

Abstract - CoSSMic (Collaborating Smart Solar powered Micro-grids) is an EU funded project aimed at developing a system for smart management and control of solar energy. The system must be relevant to a community of end-users and other stakeholders. Two processes are described to contribute in meeting this aim, user-centered design and lean startup product design. Iterative approach to the design of the system which incorporates these two processes are described.

  • Two feasibility studies are conducted in Konstanz, Germany and the Province of Caserta, Italy. Both trial locations are quite different in terms of population, solar irradiation, available equipment and electrical consumption.
  • Iterative approach with an emphasis on user-centered design and lean startup product design.
  • Establishment of workshops to design the model and strucure.
  • quite successful in building up relations between potential users and the project teams
