Resident & Developer Solar Resources
If you’re thinking about investing in solar panels on the roof of your home or business, or are considering a larger project, you may have a number of questions. Select from the list below and use the + sign to expand the content.
The “Right to Light” is an interesting discussion. No laws at the federal level protect a landowner’s ability to access sunlight or to develop solar energy on their property. In Connecticut, there are not State laws to this effect either. In fact, there may be a number of legal barriers to ensuring your access to light: municipal zoning or forestry regulations that prevent the cutting down of trees, a height ordinance that rooftop panels would violate, or homeowner’s association rules meant to standardize the appearance of homes. To complicate matters, sometimes the obstruction of sunlight comes from structures or trees on a neighbor’s property. Although Connecticut does not guarantee “solar rights” in the traditional sense, we encourage homeowners to work with their neighbors and their local land use office to come up with creative solutions.

- Although the report linked above was published in 2007, CT OLR has verified that the information “is still accurate, though we have not done any research into whether other municipalities in the state have enacted zoning provisions that specifically apply to solar access since then.”
While you don’t need to be an expert in the solar industry to get panels installed, every consumer should know enough information to protect themselves. Online resources on the subject range from a high-level checklists to comprehensive guides. The links below are in order from simplest to most detailed.

A list of solar PV installers located in one of NVCOG’s member municipalities can be generated from the Energize CT Contractor Database. Select “Home,” “Business,” or “Town,” depending on your needs. Then select “Solar PV Service.” Click “Submit.” The first column in the list will have an address for the company. There are a number options within the NVCOG region.

Project Sunroof leverages Google Maps’ GIS technology to help residents across the U.S. calculate potential savings after installing solar panels. The algorithm is based on a number of factors, including:
- Roof orientation and size
- Annual hours of sunlight exposure
- Tree cover
- State and federal incentives
All you need to do is enter your address and provide the average cost of your monthly electric bill! Even if you’re unsure about solar, consider making use of this tool and seeing how much you could save. Click below to get started:
Just as access to unobstructed sunlight impacts the siting of solar projects, so does the land use of the subject and surrounding properties. Some land uses are particularly well-suited to solar. Below are resources to guide the development of solar based on the principal land use of the property.
