“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..
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
- 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
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
Note - special purpose entity mave have issues in obtaining ITC tax credits because of it recuries taxable income members.
- 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
- sample budget for community solar
- 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
ENERGY, N.C., 50States. 24th Jan 2017
- US Distributed Solar Market
- Net Metering Policy Changes
- Community solar Policies
- Proposed Charges on Residential Solar Customers
- Third- party solar ownership
- Utility-led Rooftop Solar Program Updates
- Questions answered with this:
1. How are state regulatory bodies and legislatures and electric utilities addressing fast growing markets for distributed solar PV?
2. What changes to traditional rate design features and net metering policies are being proposed, approved, and implemented?
3. Where are distributed solar markets potentially affected by policy or regulatory decisions on community solar, third-party solar ownership, and utility-led residential rooftop solar programs?
- Report include actions on:
1. Significant changes to state or utility net metering laws and rules, including aggregate caps, system size limits, aggregate net metering rules, and compensation rates for net excess generation.
2. Changes to statewide community solar laws and rules, and individual utility-sponsored community solar programs arising from statewide legislation.
3. Legislative or regulatory-led efforts to study the value of solar, net metering, or distributed solar generation policy, e.g., through a regulatory docket or a cost-benefit analysis.
4. Utility-initiated rate requests for charges applicable only to residential customers with solar PV or other types of distributed generation, such as added monthly fixed charges, demand charges, stand-by charges, or interconnection fees.
5. Utility-initiated rate requests that propose a 10% or larger increase in either fixed charges or minimum bills for all residential customers.
6. Changes to the legality of third-party solar ownership, including solar leasing and solar third-party solar PPAs, and proposed utility-led rooftop solar programs.
The growth in solar PV market is expected to continue, particularly due to the recent extension of the federal investment tax credit. The credit, which was previously set to expire for residential systems at the end of 2016, will be available at its current 30% level through 2019, then will step down over the next several years and expire at the end of 2021. The credit will remain at 10% permanently for commercial systems after 2021. GTM Research estimates that the extension of the federal investment tax credit will increase residential solar PV installations by 35% between 2016 and 2020 compared to a scenario without the extension.
- The solar PV system is located at a residential location in the U.S.
- You own the solar PV system (e.g., you purchased it with cash or through financing – but are not leasing it or in
an arrangement to purchase electricity generated by a system you do not own).
- The solar PV system is new or being used for the first time. The ITC can only be claimed on the “original
installation” of the solar equipment.
- It is not a necessity to be a homeowner to claim the tax credit. A tenant-stockholder at cooperative housing corporation and members of condominiums are still eligible for the tax credit if they contribute to the costs of an eligible solar PV system.
- OFF-SITE COMMUNITY SOLAR PROGRAM: There is an example for this. "For example, one arrangement is the creation of a “Special Purpose Entity,” where community members form and invest in a business that operates the community solar project. If your participation is limited to investing in the community solar project and you do not participate in the operation of the project on a regular, continuous, and substantial basis, you are constrained in taking advantage of the ITC because you are considered a “passive investor.” IRS rules require that a tax credit associated with a passive investment only be used against passive income tax liability, which only applies to income generated from either a rental activity or a business in which the individual does not materially participate. Many homeowners will therefore not have passive income against which the ITC can be claimed."
How solar+storage Could Protect Multifamily Affordable Housing from Power Outages at little or no net Cost 
1. Between $17.9 billion and $23.3 billion of electricity value alone would flow into these communities, if all low-income households went solar.
2. The installation and operation of a full low-income solar build-out would also contribute an additional $18.7 billion of local economic output each year, resulting in roughly 138,376 jobs.
3. The 49.1 million households that earn less than $40,000 of income per year make up 40 percent of all US households but only account for less than 5 percent of solar installations. Lower income households face key barriers that are difficult to overcome.
4. Lower income households are less likely to own their roof due to higher rates of living in multi-family buildings and being renters (49.1 percent of households with incomes less than $40,000 are renters versus 21.8 percent of households with incomes greater than $40,000).
5. Electricity costs account for 5.7 percent of the median low-income family’s budget, while they only account for 1.9 percent for other families.
6. A typical low-income family consumes roughly 10,060 kilowatt-hours of electricity at a cost of $1,272 per year. Other, more affluent families consume roughly 11,720 kilowatt-hours of electricity on average, at a cost of $1,558 per year. Nevertheless, low-income families do use less electricity overall and use only 22 percent of the electricity used in American homes despite accounting for roughly 25 percent of all housing units.
7.The federal government spends billions of dollars each year on energy for low-income households:
- In fiscal year 2014, the federal government provided states with $3.4 billion through the Low-Income Home Energy Assistance Program (LIHEAP) to assist low-income families with their home energy bills. Historically, these LIHEAP dollars only cover about 15 percent of all eligible low-income households.
- The U.S. Department of Housing of Urban Development (HUD) expends about $6.3 billion on energy costs each year for federally assisted housing.

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.
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

Abstract - Method is used to estimate hourly, global, diffuse solar radiation for horizontal surfaces and total solar radiation on inclined and vertical surfaces at different orientations with greater accuracy for any location.
- Hourly global & diffuse solar radiation is measured to calculate the direct radiation from the total solar radiation
- The hourly solar radiation has also been calculated and compared using two methods: 1. Gueymard daily integration
approach from the measured daily solar radiation data & 2. model to estimate global solar radiation using temperature and sunshine hour data has been developed (Chandel et al.) which is used to calculate the hourly solar radiation Data.
- Total solar radiation on the inclined surfaces and vertical surfaces for different orientations have also been estimated.
Abstract -It is by now familiar that in the deployment of solar photovoltaic (PV) systems, the cost dynamics of major system component like solar cell/module is subjected to experience curve effects driven by production learning and research and development at the supplier side. What is less clear, however, is the economics of system integration or system deployment that takes place locally close to the user, involving other market players, in the downstream solar PV value chain. Experts have agreed that suppliers of solar PV system must customize their flexible characteristics to address local unique users’ and applications requirements and compete on price/performance basis. A lack of understanding of the drivers of the economics of system customization therefore is a deficiency in our understanding of the overall economics of this renewable energy technology option.

Abstract Community is a much used word that is readily attached to projects, initiatives and policies as part of the discursive politics of modern governance. In this viewpoint, we consider the way in which community has become attached to renewable energy projects in the UK, both in grassroot action and in mainstream energy policy. We ask what those involved have seen as distinctive about community renewable energy projects that makes them different from other renewable energy installations. We identify a diversity of understandings and interpretations that revolve around questions of both process (who the project is by) and outcome (who the project is for). We evaluate the implications of this diversity, identifying the importance of the process of project development for realising the catalytic and learning effects of meaningful and substantial local involvement.
- Ways in which word community is interpeted
- Participation of Local and openess in project helps.
- diversity in income different opportunities for financing.
Abstract This paper on community-owned means of renewable energy production and use, reviews experience to date in the UK and the incentives for and barriers limiting current and future growth. A broad view is taken of what the meaning of ‘community-owned production and use’ might constitute, as there are different models of community ownership, different notions of community and different degrees of connection or disconnection between production and use.
- models of ownership 1) cooperative model 2) community charities 3)development trusts 4)shares owned by local community
- incentives for community projects
- Barriers w.r.t to community projects
The transformation of southern California's residential photovoltaics market through third-party ownership
Third-party photovoltaics (PV) ownership is a rapidly growing market trend, where commercial companies own and operate customer-sited PV systems and lease PV equipment or sell PV electricity to the building occupant. Third-party PV companies can reduce or eliminate up-front adoption costs, reduce technology risk and complexity by monitoring system performance, and can repackage the PV value proposition by showing cost savings in the first month of ownership rather than payback times on the order of a decade. We find that the entrance of third-party business models in southern California residential PV markets has enticed a new demographic to adopt PV systems that is more highly correlated to younger, less affluent, and less educated populations than the demographics correlated to purchasing PV systems. By enticing new demographics to adopt PV, we find that third-party PV products are likely increasing total PV demand rather than gaining market share entirely at the expense of existing customer owned PV demand. We also find that mean population demographics are good predictors of third-party and customer owned PV adoption, and mean voting trends on California carbon policy (Proposition 23) are poor predictors of PV adoption.
- Third party ownership details not retailed to community.
Abstract What explains the galvanising of communities to participate actively in energy projects? How do groups mobilize to overcome the often formidable barriers highlighted in the existing literature? Drawing on original qualitative research of 100 community energy groups in Scotland, including six in-depth case studies, we explain how effective mobilization occurs and the political dynamics surrounding such mobilization. To capture these dynamics, we adapt theories offered by literature on social movements, with a particular focus on resource mobilization theories. Applying our adapted framework, we identify two particular sets of resources shaping community energy mobilization: (i) structural resources, which refer to the broad political context structuring and constraining opportunities for community energy mobilization; and (ii) symbolic resources—less tangible resources used to galvanise participants. We investigate to what extent our case study groups were able to draw upon and exploit these resources. We find that structural resources can either facilitate or hinder mobilization; what matters is how state resources are exploited and constraints mitigated. The use of symbolic resources was highly effective in aiding mobilization. Each of the groups examined – despite their considerable variation – effectively exploited symbolic resources such as shared identity or desire for strong, self reliant communities

Three is a crowd? Exploring the potential of crowdfunding for renewable energy in the Netherlands
Abstract There is a huge gap between demand and supply of finance for energy transitions, and the financial and economic crisis have had a negative impact in the already meagre funds for transforming the energy system towards renewable sources. In this paper we explore whether crowdfunding for renewable energy, as a novel sociotechnical practice developed in a niche, has the potential to break through and transform both the energy and the financial regimes, utilising the Multi-Level Perspective theory. We empirically investigate crowdfunding platforms linked to renewable electricity projects in the Netherlands. The main conclusion is that the volume of crowdfunding today is low, but the dynamic of these projects holds potential. There is limited indication of learning processes until now, as well as limited support from regime actors, pointing at a low level of niche stabilization and break-through potential, which may however be related to the early stage of development of crowdfunding in the Netherlands. On the other hand, the heterogeneity of crowdfunders is very promising. Platforms dedicated to renewable electricity exclusively, and with an investment based business model seem to be the most successful. We show how governmental market regulation and support mechanisms are shaping crowdfunding as a business model, and discuss the implications for other countries.
- The volume of crowdfunding for renewable energy projects is low, but its dynamic holds potential.
- There is limited support of crowdfunding for renewables from powerful actors.
- Crowdfunders exhibit a variety of normative, gain and even hedonic motivations.
- Governmental market support and regulations are shaping crowdfunding as a business model.

Business model innovations for deploying distributed generation: The emerging landscape of community solar in the U.S.
Abstract Increasing penetration of residential photovoltaic (PV) systems has intensified concerns over the related impacts on utility revenue and the equity of deployment subsidies. Community solar (CS) has surfaced as an alternative deployment model for PV that could potentially mitigate these concerns, while integrating distributed solar PV. Given the potential that CS holds in stabilizing the customer-utility relationship amid deeper penetration of distributed solar, in this paper we combine four complementary datasets to analyze how policy, regulatory, and market factors impact the deployment of CS. Specifically, we present a detailed assessment of CS deployment in the United States, including pertinent insights relating to nameplate capacity, billing models, propensities of off-taker utilities to adopt different types of CS, and local market and policy drivers. We find that accounting for both underlying demand and policy/regulatory conditions is essential for understanding the nuanced connections between utility strategy and CS adoption. A particularly interesting finding, stemming consistently across the multiple data streams we analyze, is that utilities are motivated to develop CS not only to satisfy consumer demand or regulatory requirements for renewable energy, but also to alleviate revenue losses related to residential solar PV.
- survey of the utilities and how they feel about CS.
- Main concern of Utilities is that the maintaince of transmission grid is not fairly compensated in Pv rooftop solar.

Guidebook for community solar programs in Michigan Communities (2014)
- The Act required Michigan electric providers to ramp up their use of renewable energy in order to obtain 10% of their electricity sales from renewable resources in 2015.
- Cherryland Electric Cooperative and Traverse City Light & Power, initiators of Michigan’s first Community Solar project.
- The modeling tools consist of the DOE’s “Systems Analysis Model” (SAM), economic modeling software for renewable energy projects, and the newly created “Michigan Community Solar Analysis Tool”, an Excel spreadsheet-based tool that uses data from the SAM modeling tool to analyze various Community Solar configurations. These tools enable Michigan utilities, businesses, neighborhood associations, citizens’ groups, and others to analyze the financial effects of using various structures and configurations in the development of their projects.
- Despite having less access to solar radiation than Michigan, Germany is setting the global record for solar power production. Community solar programs need to be accelerated.
- Michigan-based Dow Chemical Company is currently manufacturing a shingle product, which protects roofs like a standard shingle and contains solar cells that can power a home.
- The AEPPTE expired on December 31, 2012, leaving the state without a property tax incentive, although there have been several attempts to reintroduce legislation that would continue the exemption and clarify the real versus personal property issue.
- Michigan does not currently have any solar access laws.
- For a comprehensive list of resources Appendix III
- Colorado (followed by Arizona) has the most Community Solar projects.
- Four main business model :Buy PV power, Lease PV panels, Purchase PV panels, Invest in a PV project
