Sites Suitability
Installing solar on the roof may seem straight forward, however, a number
of factors will need to be taken into consideration such as the roof
condition, structural conditions, site alignment and electrical configuration.
Similarly for wind generation, consideration needs to be given to the wind
conditions at the site, zoning requirements and the availability of space for
installation. Engaging an experienced professional to assess the suitability
of the site for renewables should be the first step in assessing whether
renewables are an option for your site.
Building Ownership
If the company is the sole owner of the building or site this is pretty
straight forward. However properties (mainly in the commercial space)
often have complicated building ownership structures or tenancy and
lease agreements such as via limited companies which may make it more
difficult to sign agreements for solar. In addition to this tenants who
wish to obtain the benefits of installing onsite renewables may not be in
a position to do this due to their current lease arrangements with their
landlords. The U.S. Department of Energy’s Better Buildings Alliance
program has recently published a report Promoting Solar PV on Leased
Buildings Guide (Benefits, Barriers and Strategies) that provides guidance
to landlords and tenants who wish to install solar on the building they own
or occupy.
Financing Options
There are now a number of financing options available for RE projects. If
the finance is available, it is an option to purchase the system up-front.
By owning the system, it is possible to take advantage of tax incentives,
grants and in some instances to offset the systems cost with Renewable
Energy Credits. Where the up-front capital is not readily available to
purchase the system outright other options available include.
Three Onsite Energy Renewables
There are a number of onsite renewables available such as solar, wind, biomass,
geothermal heat pumps and fuel cells. Solar PV is by far the most popular due
to the increasingly affordable installation costs, good return on investment and
low maintenance requirements. However, there are some things to consider when
assessing the suitability of the site. This includes:
