Host Site Considerations1. Do you have a good site?

http://solar.maps.umn.edu/app/2. Term of lease – 25 years or longer3. Form of payment - $ / month? $ / year? In

form of a subscription?4. How much do you need to be paid to make

it worth it?5. What costs might you

incur for site prep, maintenance or restoration?

6. Roof or ground mount?

Page 24: Minneapolis Neighborhoods Community Solar Presentation

Host Site Considerations

Land Lease• How much space? 1 MW

needs around 5-8 acres. • Zoning code issues? • Site prep, maintenance,

restoration: Who does it? Who pays for it?

• Special site concerns regarding access, view shed, etc.?

• Could the land be used for a high-value purpose?

Roof Lease• How old is your roof? 25

year term (or longer)• How much space do you

have? 1 MW system needs around 150,000 sq ft.

• Penetrating or not? If it does, does it violate roof warranty?

• Maintenance and Access?• Whose insurance covers

what? • Site restoration?
